Ordinance of September 5, 1979, on Road Signage (OSR) - Contents, Abbreviations, and Definitions (SSV)

This ordinance governs the signs, markings, and advertisements on roads and their surroundings, the signals and instructions to be given by the police, and determines the necessary measures and restrictions for traffic. In the context of this ordinance, the following definitions apply: a. DETEC stands for the Federal Department of the Environment, Transport, Energy and Communications; b. FEDRO denotes the Federal Roads Office; c. authority refers to the entity that is competent according to cantonal law to order the installation or removal of signs and markings; d. administrative procedure law is the Federal Law of December 20, 1968, on Administrative Procedure; e. LCR refers to the Federal Law of December 19, 1958, on Road Traffic; f. OCR is the ordinance of November 13, 1962, on the Rules of Road Traffic; g. OETV denotes the ordinance of June 19, 1995, regarding the technical requirements for road vehicles; h. SDR is the ordinance of November 29, 2002, relating to the transport of dangerous goods by road; i. ORN refers to the ordinance of November 7, 2007, on national roads.

The numbers placed in parentheses after the designation of a signal or marking refer to the figures listed in appendix 2. The term "within localities" or "in localities" refers to an area beginning at the sign "Beginning of a locality on a main road" (4.27) or "Beginning of a locality on a secondary road" (4.29) and ending at the sign "End of a locality on a main road" (4.28) or "End of a locality on a secondary road" (4.30). The term "outside localities" or "outside of localities" refers to an area beginning at the sign "End of a locality on a main road" or "End of a locality on a secondary road" and ending at the sign "Beginning of a locality on a main road" or "Beginning of a locality on a secondary road."

Complementary plaques are panels providing additional information related to the signals (art. 63). Highways and expressways are routes designated by the sign "Highway" (4.01) or the sign "Expressway" (4.03), on which specific traffic rules apply (art. 45, para. 1). Main roads are those designated by the sign "Main road" (3.03), on which drivers, as an exception to the right-hand priority provided by law (art. 36, para. 2, LCR), have priority at intersections (art. 37, para. 1). Secondary roads are all roads whose beginning is not specifically signaled and on which general traffic rules apply (e.g., right-hand priority according to art. 36, para. 2, LCR). Roads allocated to general traffic are all roads located within localities, primarily designed to meet the requirements of motorized traffic and intended for safe, efficient, and economical transport.

...

Unless otherwise specified, the signals and markings apply to all road users.

The signals and markings are defined in Annex 2.

The signals and markings that govern not specific categories of vehicles but traffic in general must also be observed by riders and drivers of horses or other large animals, with the exception of the signal "General prohibition of passage in both directions" (2.01).

Special provisions concerning military road traffic are reserved. Art. 101, paragraphs 8 and 9, regulate the yellow and black signals addressed exclusively to military road users as well as the white and orange direction indicators addressed exclusively to civil protection personnel.

The indication signs "Parking Allowed" (4.17), "Parking with Parking Disc" (4.18), and "Parking for Payment" (4.20) as well as regulatory signs can appear as zone signs (2.59.1) on a white rectangular panel bearing the inscription "ZONE."

Zone signage is only permitted on roads located within localities.

The rights and obligations indicated by means of a zone sign apply from the start of the zone signage until the sign marking the end. The end of zone sign indicates that the general traffic rules are valid again.

A zone sign can indicate a maximum of three traffic regulations.

The signs "Zone 30" (2.59.1), "Encounter Zone" (2.59.5), and "Pedestrian Zone" (2.59.3) are only permitted on secondary roads not assigned to general traffic.

When the speed is limited to 30 km/h on a road section designated for general traffic in accordance with the requirements of Art. 108, para. 1, 2, and 4, it is possible to integrate this section into a 30 zone.

As a general rule, warning signs take the shape of an equilateral triangle with a red border and feature a black symbol on a white background. When dealing with matrix signs, the background may be black and the symbol white.

Their installation will only be ordered in locations where a driver unfamiliar with the area might not notice a danger or notice it too late.

Subject to derogatory provisions applicable to certain signs, warning signs shall be placed: a. within localities, just before the dangerous spot; if they are placed more than 50 meters ahead, the distance will be indicated on a "Distance Plate" (5.01); b. outside localities, between 150 and 250 meters before the dangerous spot; if it is impossible to comply with this rule, the distance will be indicated on a "Distance Plate"; c. on highways and semi-highways, at the dangerous spot or at most 100 meters before; as advanced signs, they will also be placed between 500 and 1000 meters before the dangerous spot and will be supplemented by a "Distance Plate."

The length of a hazardous section may be indicated on a supplementary plate "Section Length" (5.03). When this length is significant, warning signs will be repeated at appropriate intervals and may be supplemented by a "Reminder Plate" (5.04) as necessary.

Turn signals announce turns, the configuration of which (e.g., lack of banking, sharp or irregular curvature of the roadway) requires a reduction in speed.

Depending on the layout of the location, the signals "Right Turn" (1.01), "Left Turn" (1.02), "Double Turn, the first to the right" (1.03), or "Double Turn, the first to the left" (1.04) should be used.

When several turns follow each other at short distances, the signal corresponding to the first turn or the double turn shall be supplemented with an additional plaque "Length of the Section" (5.03).

As a general rule, no turn signal will be placed within localities.

The sign "Slippery Roadway" (1.05) indicates roads with particularly slippery surfaces, grooves, or sections of road particularly prone to freezing.

When the "Slippery Roadway" sign is used to indicate ice or slippery snow, it should be accompanied by the additional plaque "Icy Roadway" (5.13). This sign and its additional plaque must be removed or covered as soon as there is no longer a risk of ice formation or the presence of slippery snow.

The "Road Bump" sign (1.06) indicates road surface irregularities (e.g., bumps, depressions) that may cause dangerous jolts to vehicles or make them lose road grip.

...

The sign "Road Narrowing" (1.07) indicates that the road narrows on both sides, making crossings difficult. The sign will not be placed before construction zones signposted as such (Art. 9).

The signs "Road Narrowing on the Right" (1.08) and "Road Narrowing on the Left" (1.09) indicate that the road narrows on one side or that obstacles dangerously encroach on the edge of the road, making crossings difficult. Such obstacles will be marked in accordance with Art. 82.

The elimination of a traffic lane on a roadway comprising several lanes in the same direction will be announced with the plaque "Traffic Lane Layout" (4.77).

The width of the road at its narrowest point will be indicated, if necessary, by the supplementary plaque "Road Width" (5.15).

The signs "Dangerous Descent" (1.10) and "Steep Climb" (1.11) indicate sections with a slope of at least 10%; the maximum slope of the descent or climb will be indicated on the sign.

The "Gravel" sign (1.12) announces the presence of small stones on the roadway.

The "Falling Rocks" sign (1.13) warns drivers of falling rocks or the presence of rocks on the road. The symbol may be laterally inverted depending on the location configuration.

The "Works" sign (1.14) announces either works being carried out on the roadway (e.g., construction, surveying, marking), obstacles that result from such works (e.g., material deposits, wide-open holes), or roadway irregularities or narrowings. The signage for construction sites is additionally governed by Art. 80.

This sign will also be placed to announce works being carried out in the immediate vicinity of the roadway, when they are likely to impede traffic.

The signals "Barriers" (1.15) and "Level Crossing without Barriers" (1.16) are used to indicate level crossings as specified under arts. 92 and 93.

The "Barriers" signal may also indicate the perimeter of an aerodrome, etc.

...

The signal "Tramway or Road Railway" (1.18) indicates the presence of railway vehicles on the road, particularly intersections traversed by such vehicles.

The sign "Pedestrian Crossing" (1.22) indicates crossings that cannot be seen from a distance of at least 200 meters. It can only be placed outside of built-up areas and at approaches to pedestrian crossings that comply with recognized road safety standards.

The sign "Children" (1.23) indicates that the presence of children on the roadway is often to be expected. It will be placed near schools, playgrounds, etc.

The sign "Cyclists" (1.32) indicates that cyclists and moped riders frequently enter or cross the road; it should only be placed outside intersections.

The sign "Wildlife Crossing" (1.24) indicates that there is a likelihood of wildlife on the roadway. Generally, the length of the section where this danger exists will be indicated by the supplementary panel "Length of Section" (5.03).

The "Animals" sign (1.25) indicates the presence of unattended animals on the roadway; the silhouette of the animal indicates the species of animals primarily concerned. This sign will be placed in grazing areas where no regulation requires fencing; furthermore, during the ascent to or descent from pasture, it will be placed as long as herds are moving on the roadway. If necessary, it will be placed on major roads frequently used by herds.

The Federal Roads Office (OFROU) may authorize the use of other animal silhouettes in accordance with Art. 115, para. 2.

The sign "Two-Way Traffic" (1.26) informs drivers that they should expect vehicles coming from the opposite direction.

The "Two-Way Traffic" sign shall be placed: a. on highways, when a traffic lane is reserved for vehicles coming from the opposite direction (e.g., due to roadworks or accidents on the opposite carriageway); b. at the beginning of expressways, after the "Expressway" sign (4.03) when they follow onto a highway; c. ... d. at the end of one-way roads, as soon as they are followed by a section open to two-way traffic.

The signal "Traffic Lights" (1.27) indicates a traffic light installation before which the driver must stop if necessary. It shall be placed before traffic light installations located outside of urban areas and may be used as an advance signal to announce traffic lights used to temporarily close certain traffic lanes (Art. 69, Para. 4); within urban areas, it may be placed on high-speed roads or other roads where the traffic light installation cannot be seen in time.

and 3 ...

The signal "Traffic Jam" (1.31) warns drivers of the presence of stationary or slow-moving queues of vehicles. It is only permitted to place it permanently at locations where traffic jams are likely to occur frequently.

The "Other Dangers" sign (1.30) warns drivers about the presence on the roadway of dangers for which no specific sign is provided. If necessary, the nature of the danger will be indicated on an additional plaque or, if it is a short-term signage, by means of folding signs, under the symbol, within the field bordered in red.

The "Other Dangers" sign will be placed, if necessary, before police interception posts (Art. 31, para. 2); furthermore, outside of localities, it will be used to announce that the traffic is controlled by the police.

Art. 65, para. 7, applies when it comes to warning road users against noise unexpectedly caused by artillery pieces.

Mandatory signs indicate an obligation or a prohibition; they generally have the shape of a disc. Prohibition signs typically have a red border and a black symbol on a white background; if they are matrix signs, the background may be black with a white symbol. Mandatory signs have a narrow white border and a white symbol on a blue background. If the signage is intended for short-term use, mandatory signs can be displayed on a foldable white signal of triangular shape.

Subject to any exceptional provisions regarding certain mandatory signs, the announced requirement applies at the location or from the location where the sign is placed until the end of the next intersection; at this location, the sign will be repeated if its validity needs to extend further. The signs "Maximum Speed" (2.30), "Minimum Speed" (2.31), "No Overtaking" (2.44), "No Overtaking by Trucks" (2.45), "No Stopping" (2.49), and "No Parking" (2.50) must be observed until the corresponding end of prescription sign (2.53, 2.54, 2.55, 2.56, 2.58) but at most until the end of the next intersection. The sign "Maximum Speed 50, General Limit" (2.30.1) applies throughout compactly built-up areas within localities (Art. 22, para. 3; Art. 4a, para. 2, OCR).

When a mandatory sign announces a requirement that must only be observed farther ahead, a "Distance Plate" (5.01) must be added; when a requirement is repeated, a "Reminder Plate" (5.04) must be added to the sign. Traffic prohibitions as well as weight and dimension limitations will be announced early enough to allow drivers to take a detour.

On long stretches, mandatory signs will either be repeated as needed at appropriate intervals, equipped with a "Reminder Plate" (5.04) for this purpose, or supplemented by the "Section Length" plate (5.03).

Exceptions to the requirements indicated by signs (e.g., "Residents Allowed," "Allowed with Special Written Permission") shall be mentioned on a supplementary plate according to the provisions of Articles 63 to 65.

The use of supplementary plates, which make the signaled requirements more stringent, is only permitted if the regulation cannot be signaled otherwise.

When there is a traffic prohibition or a limitation on weight or dimensions, the inscription "Residents Allowed" means that it is permitted to deliver or pick up goods for the residents or on neighboring properties, that the residents and their visitors, as well as people performing work on neighboring properties, may make trips there, and that third parties may transport these persons there.

The signal "General prohibition of traffic in both directions" (2.01) indicates that traffic is, in principle, prohibited in both directions for all vehicles.

When, at an intersection, access to a road is blocked by the signal "General prohibition of traffic in both directions," but an exit is still possible to a limited extent (e.g., for local residents), the priority of exiting vehicles will be canceled by the signals "Stop" (3.01) or "Yield" (3.02).

The signal "No entry" (2.02) indicates that no vehicles are allowed to pass, but traffic in the opposite direction is permitted. At the other end of the road, the signal "One way" (4.08) will be placed.

The signals "General prohibition of traffic in both directions" and "No entry" do not apply to: a. handcarts with a maximum width of 1 m; b. baby carriages; c. non-motorized wheelchairs; d. motorized wheelchairs and electric scooters, provided they are used by persons with reduced mobility; e. bicycles, provided they are being pushed; f. mopeds, provided their engine is turned off and they are being pushed; g. two-wheeled motorcycles, provided their engine is turned off and they are being pushed.

If access to a road is prohibited by the signal "No entry" (2.02), the authority provides an exception for bicycles and mopeds, unless lack of space or other reasons prevent it. It can provide other exceptions, particularly for public line traffic vehicles.

To indicate that one-way traffic is alternately allowed in one direction or the other, the signal "No entry" will be accompanied by an additional plaque mentioning the authorized access times, the length of the section, and the time generally required for vehicles to complete this route.

...

Partial traffic bans prohibit passage to specific vehicles; they have the following meanings: a. the sign "No Entry for Motor Vehicles" (2.03) pertains to all multi-track motor vehicles, including motorcycles with sidecars, with the exception of mopeds; b. the sign "No Entry for Motorcycles" (2.04) pertains to all motorcycles; c. the sign "No Entry for Bicycles and Mopeds" (2.05) prohibits circulating with bicycles or mopeds; the sign "No Entry for Mopeds" (2.06) prohibits circulating with heavy or fast mopeds; d. the sign "No Entry for Trucks" (2.07) pertains to all heavy motor vehicles used for transporting goods; e. the sign "No Entry for Coaches" (2.08) pertains to all coaches; f. the sign "No Entry for Trailers" (2.09) pertains to all motor vehicles towing a trailer, except for agricultural trailers and trailers for bicycles or mopeds; the weight specified on an additional plaque indicates that trailers whose total weight registered on the circulation permit does not exceed the weight indicated by the sign are not subject to the ban; fbis. the sign "No Entry for Trailers Other Than Semitrailers and Trailers with Central Axles" (2.09.1) pertains to all motor vehicles towing a trailer, except for semitrailers and trailers with central axles. The weight indicated on an additional plaque signifies that trailers whose total weight registered on the circulation permit does not exceed the weight indicated by the sign are not subject to the ban; g. the sign "No Entry for Vehicles Transporting Dangerous Goods" (2.10.1) pertains to all vehicles that must be signaled in accordance with the ADR; in tunnels, it also applies to all transport units that the ADR equates with said vehicles. For tunnels, the tunnel category according to appendix 2 ADR must be indicated on an additional plaque using the corresponding letter; h. the sign "No Entry for Vehicles with Loads that Could Pollute the Waters" (2.11) pertains to all vehicles transporting dangerous goods in the sense of appendix 2, number 2.2 ADR; i. the sign "No Entry for Animals" (2.12) prohibits the traffic of draft, saddle, and pack animals as well as the driving of livestock.

Two symbols indicating prohibition, or three symbols in the case of minor secondary roads (art. 22, para. 4) or roads within localities, may appear on a sign, such as "No Entry for Motor Vehicles and Motorcycles" (2.13) "No Entry for Motor Vehicles, Motorcycles, and Mopeds" (2.14).

The sign "No Entry for Pedestrians" (2.15) prohibits access to pedestrians and users of devices similar to vehicles.

The sign "No Skiing" (2.15.1) prohibits skiing in all its forms and the sign "No Sledding" (2.15.2) prohibits sledding in all its forms. These signs must be removed at the end of the winter season.

The sign "No Entry for Devices Similar to Vehicles" (2.15.3) prohibits the use of such devices.

The sign "Maximum Weight" (2.16) prohibits the movement of vehicles and vehicle combinations whose actual weight exceeds the indicated figure. The actual weight is the real weight of the vehicle or vehicle combination with its occupants and load at the time of weighing (art. 7, para. 2, OETV).

When an additional plate added to the "Maximum Weight" sign authorizes a higher weight for vehicle combinations, the weight of each vehicle within the combination must not exceed the number indicated on the sign.

The sign "Axle Load" (2.17) prohibits the movement of vehicles whose axle bears a load greater than that indicated. When axles are less than one meter apart, the load they bear together must not exceed the indicated amount.

The sign "Maximum Width" (2.18) prohibits the circulation of vehicles whose width, including the load, exceeds the indicated figure; the use of roads marked with a maximum width of 2 m 30 by certain wider vehicles is governed by Art. 64, para. 2, OCR.

The sign "Maximum Height" (2.19) prohibits the circulation of vehicles whose height, including the load, exceeds the indicated figure. It will be placed near the obstacle itself before underground passages, tunnels, galleries, covered bridges, constructions protruding over the roadway, etc., when vehicles with a height of 4 m cannot pass safely at that location.

The sign "Maximum Length" (2.20) prohibits the circulation of vehicles and vehicle combinations whose length, including the load, exceeds the indicated figure.

The signs "Maximum Speed" (2.30) and "Maximum Speed 50, General Limit" (2.30.1) indicate in km/h the speed that vehicles must not exceed even if the road, traffic, and visibility conditions are good. The obligation to adhere to the posted maximum speed is lifted by the sign "End of Maximum Speed" (2.53) or "End of Maximum Speed 50, General Limit" (2.53.1).

When it is necessary, on a high-traffic road, to significantly reduce vehicle speed (art. 108), the permitted limit will be gradually decreased.

The beginning of the general 50 km/h speed limit (art. 4a, para. 1, letter a, OCR) will be announced by the sign "Maximum Speed 50, General Limit" (2.30.1) as soon as there is a densely built-up area on one side of the road. The end of the general 50 km/h speed limit will be indicated by the sign "End of Maximum Speed 50, General Limit" (2.53.1); this sign will be placed where neither side of the road is densely built-up.

Signs announcing the beginning or end of the general 50 km/h speed limit are not necessary on less important secondary roads (such as roads that do not directly connect towns or outer districts, agricultural service roads, forest paths, etc.; art. 4a, para. 2, OCR).

On semi-highways, the general speed limit (art. 4a, para. 1, OCR) will be indicated by signs.

The sign "Zone 30" (2.59.1) designates roads, located in neighborhoods or housing developments, on which drivers are required to drive in a particularly cautious and considerate manner. The maximum speed is set at 30 km/h.

The "Shared Zone" sign (2.59.5) designates roads located in residential or commercial areas, where pedestrians and users of devices equivalent to vehicles may utilize the entire traffic area. They have the right of way but must not unnecessarily obstruct vehicles.

The maximum speed is set at 20 km/h.

Parking is permitted only in places designated by signs or markings. The rules governing parking in general apply to the parking of bicycles and mopeds.

The "Pedestrian Zones" (2.59.3) are reserved for pedestrians and users of devices analogous to vehicles. When an additional panel exceptionally permits limited vehicle traffic, such vehicles may proceed at no more than walking pace; pedestrians and users of devices analogous to vehicles have the right of way.

Parking is only authorized in areas designated by signals or markings. The rules generally governing parking apply to the parking of bicycles and mopeds.

The "Minimum Speed" sign (2.31) indicates in km/h the speed below which vehicles must not circulate when road, traffic, and visibility conditions are favorable. Vehicles that cannot or are not allowed to operate at the indicated speed (e.g., due to the characteristics of the vehicle or the load) are not permitted to continue their course. The obligation to observe the indicated minimum speed is lifted by the "End of Minimum Speed" sign (2.54).

When the minimum speed must be observed across the entire roadway, it must be announced early enough to allow drivers to take an alternative route (Art. 16, para. 3).

To indicate the mandatory direction that drivers must follow, the following signs shall be used: a. "Mandatory Direction to the Right" (2.32), "Mandatory Direction to the Left" (2.33): the driver must turn to the right or to the left before the sign; b. "Obstacle to be Bypassed on the Right" (2.34), "Obstacle to be Bypassed on the Left" (2.35): the driver must bypass the obstacle on the right or the left at which the sign is placed; c. "Proceed Straight Ahead" (2.36): the driver may not turn to the right or to the left.

The signs "Turn Right" (2.37) and "Turn Left" (2.38) require the driver to turn right or left at the specific location and, on highways, to cross to the opposite carriageway in the indicated direction.

The signs "Turn Right or Left" (2.39), "Proceed Straight Ahead or Turn Right" (2.40), as well as "Proceed Straight Ahead or Turn Left" (2.41) require the driver to take, at the specific location, one of the indicated directions.

The sign "Roundabout" (2.41.1) indicates the direction of the circular movement that vehicles are obliged to follow in roundabouts; it is placed before the entrance, under the "Yield" sign (3.02), and may be repeated on the central island. Combined with the "Roundabout" sign, the "Yield" sign indicates to the driver that they must give priority to vehicles approaching from the left in the roundabout.

When used with the sign "No Entry for Vehicles Carrying Dangerous Goods" (2.10.1), the sign "Mandatory Direction for Vehicles Carrying Dangerous Goods" (2.41.2) indicates the direction that vehicles subject to this restriction are obligated to take.

The signs "No Right Turn" (2.42) and "No Left Turn" (2.43) indicate that turning right or left at the specified location is prohibited.

These signs shall not be placed when the direction to be taken can be unequivocally indicated by the signs "Turn Right" (2.37) or "Turn Left" (2.38).

The sign "No Overtaking" (2.44) prohibits drivers of motor vehicles from overtaking vehicles with wheels placed side by side, trams, and road railways when these vehicles are in motion.

The sign "No Overtaking by Trucks" (2.45) prohibits drivers of heavy motor vehicles used for the transport of goods and heavy work motor vehicles from overtaking motor vehicles with wheels placed side by side, trams, and road railways when these vehicles are in motion.

These two signs do not prevent drivers from overtaking, provided there is no danger, vehicles whose maximum speed is limited to 30 km/h (single-axle vehicles, hand carts with motor, motor carts, work carts, agricultural motor vehicles; Art. 11, para. 2, letter g, 13, para. 3, letter b, 17 and 161 to 166, OETV). Trams and road railways in motion may be overtaken on the right.

The overtaking prohibitions indicated will be lifted by the signs "End of No Overtaking" (2.55) and "End of No Overtaking by Trucks" (2.56).

The sign "No U-turn" (2.46) prohibits vehicles from turning on the road at the indicated location.

When the prohibition applies to a specific section, the length of that section will be indicated by an additional plaque "Length of Section" (5.03).

The "minimum distance" sign (2.47) requires drivers of motor vehicles and articulated vehicles, whose total weight indicated in the registration certificate exceeds 3.5 t, to maintain the indicated minimum distance between each other.

...

When the regulation applies to a section of a certain length, the sign will be equipped with the supplementary plate "Length of Section" (5.03).

The sign "Mandatory Snow Chains" (2.48) means that multi-track motor vehicles may only use the section in question if at least two driving wheels on the same axle, or one per side in the case of twin wheels, are equipped with metallic snow chains; this provision applies, by analogy, to motor tricycles. Similar devices made from other materials, which are authorized by the Federal Roads Office (OFROU), are also permitted.

The sign will be removed as soon as good tires are sufficient to travel on the section.

The requirement indicated will be revoked by the sign "End of Snow Chain Requirement" (2.57).

The signs "No Stopping" (2.49) and "No Parking" (2.50) respectively prohibit the voluntary stopping of vehicles or their parking on the side of the road equipped with such a sign. Parking of a vehicle is defined as a stationary position that is not solely for the purpose of picking up or dropping off passengers or loading or unloading goods (Art. 19, para. 1 ROSR).

When the "No Stopping" sign (2.49) is located by the roadside, the prohibition also applies to the adjacent sidewalk.

The beginning, reminder, or end of the prohibition will be indicated by the "Start of Regulation Sign" (5.05), the "Reminder Sign" (5.04), or the "End of Regulation Sign" (5.06). Depending on local conditions, the scope of the prohibition may also be indicated using the "Direction Sign" (5.07).

Temporary exceptions to the stopping prohibition will be announced by the supplementary plaque "Exception to No Stopping" (5.10) and temporary exceptions to the parking prohibition by the supplementary plaque "Exception to No Parking" (5.11) (Art. 65, para. 2).

The signal "Stop Near Customs Post" (2.51) requires drivers to stop near the customs office. If customs authorities temporarily waive customs checks, drivers shall pass through the customs area at a speed of no more than 20 km/h.

The signal "Police" (2.52) with the inscription "Police" instead of "Customs/Zoll" requires drivers to stop. It is placed by the police; Art. 15, para. 2, applies to advance signage using the "Other Dangers" signal (1.30).

...

The signs "End of Maximum Speed" (2.53), "End of Maximum Speed 50, General Limit" (2.53.1), "End of Minimum Speed" (2.54), "End of Overtaking Prohibition" (2.55), and "End of Truck Overtaking Prohibition" (2.56) indicate that the previously signaled prohibition is lifted.

The "Free Passage" sign (2.58) indicates that multiple previously signaled traffic restrictions imposed on moving vehicles end and the general traffic rules are valid again. On highways, the end of roadworks is announced by this sign, provided that no signaled restrictions remain or begin. Existing restrictions that remain valid must be repeated.

The "End of Obligation to Use Snow Chains" sign (2.57) indicates that snow chains are no longer mandated.

Partial circulation bans on certain lanes are lifted using the end of prohibition signs (2.56.1).

...

The sign "Bicycle Lane" (2.60) requires cyclists and moped riders to use the lane indicated to them by this sign. The place where the bicycle lane ends may be indicated by the sign "End of Bicycle Lane" (2.60.1). Articles 15, paragraph 3, and 40, of the Road Traffic Regulations (OCR) govern issues of right of way and the use of the bicycle lane by other road users.

The sign "Pedestrian Path" (2.61) requires pedestrians to use the path indicated to them by the sign. The sign "Bridle Path" (2.62) requires riders and persons leading a horse by rein to use the path indicated to them by this sign. Other road users are not allowed on these paths or alleys; articles 41, paragraph 4, 43a, paragraph 1, 50, and 50a of the OCR are reserved concerning pedestrian paths.

To direct road users to a bicycle lane, a pedestrian path, or a bridle path that is located on the opposite side of the road, the corresponding sign accompanied by a "Directional Plate" (5.07) with an arrow pointing in that direction will be placed.

When a path is intended for two categories of users (e.g., pedestrians and cyclists or pedestrians and riders) and a dashed or solid line (art. 74a, paragraph 5) allows a distinct travel area to be allocated to each of the two categories of users, the corresponding symbols separated by a vertical line are shown on the sign (e.g., "Bicycle Lane and Pedestrian Path, with shared travel area"; 2.63); each category of users is required to use the part of the travel area allocated to them by the corresponding symbol. When a path without separation markings is intended to be used jointly by two categories of users, the corresponding symbols are depicted on the sign (e.g., "Bicycle Lane and Pedestrian Path without shared travel area"; 2.63.1). Cyclists and moped riders, as well as riders, must show particular consideration for pedestrians and adjust their speed to the situation. When safety requires it, they must warn pedestrians or even stop.

The sign "Roadway Reserved for Buses" (2.64) indicates a roadway reserved for public line buses, which must not be used by other vehicles; exceptions mentioned on additional panels are reserved.

When a specific lane is marked to indicate that it is reserved for the use of public line buses (Art. 74 b), the signage may be supplemented in the following manner if the yellow markings on the roadway alone are insufficient. The following may be placed: a. above the lane, the sign "Roadway Reserved for Buses" (Art. 101, para. 4) or, b. at the edge of the roadway, the "Lane Arrangement Panel Announcing Restrictions" (4.77.1), which must be presented in accordance with Art. 59; the sign "Roadway Reserved for Buses" will appear in the middle of the arrow indicating the bus lane.

Priority signals inform the driver that they must yield the right of way to other vehicles or that they have the right of way over them.

Priority signals take the form of danger signals, regulatory signs, or information signs; the principles established in chapters 2, 3, and 5 apply by analogy.

The "Stop" sign (3.01) requires the driver to come to a complete stop and give priority to vehicles traveling on the road they are approaching. Article 75, paragraphs 1, 2, and 5 apply concerning the stop line (6.10) accompanying the sign.

The "Yield" sign (3.02) requires the driver to give priority to vehicles traveling on the road they are approaching. Article 75, paragraphs 3 to 5 apply concerning the waiting line (6.13) accompanying the sign.

At intersections equipped with traffic light installations, the "Stop" and "Yield" signs should only be observed if the traffic is not regulated by traffic lights.

The signs shall be placed on the right side of the roadway, shortly before intersections. On roads marked with multiple lanes in the same direction, the signs shall generally be repeated on the left.

If the signs need to be placed more than 10 meters back, the distance will be indicated by a "Distance Plate" (5.01). The placement of the "Yield" sign at the entrances to highways and semi-highways is governed by Art. 88, para. 1.

The signs may be placed by the authority on rural roads, bicycle paths, and exits of factories, yards, or garages, at the exits of parking lots, gas stations, etc., when it is necessary to clarify priority rules (Art. 15, para. 3 OCR).

The "Stop" sign should only be placed where a stop is indispensable due to lack of visibility. It cannot be placed before railroad crossings without the authorization of the OFROU.

On a main road that loses priority to another main road, the "Stop" or "Yield" signs can be placed as advance signs before the intersection with that road. Signs equipped with a "Distance Plate" (5.01) will be placed on the right edge of the roadway, outside localities at a distance between 150 and 250 m from the intersection, and within localities, at around 50 m. On roads marked with multiple lanes in the same direction, the signs will generally be repeated on the left edge of the roadway.

The "Main Road" sign (3.03) designates priority roads and informs the driver that the right-of-way rule provided by law (Art. 36, para. 2, LCR) is nullified at upcoming intersections. The traffic regulations specifically concerning main roads (e.g., Art. 19 OCR) apply to such roads.

The "Main Road" sign shall be placed at the beginning of a road of this category and repeated, within localities immediately before the intersection, outside localities immediately after. It is not necessary to place this sign near insignificant intersections.

The signage of main roads that change direction is governed by Art. 65, para. 1.

National roads which, due to their infrastructure, are neither highways nor expressways, shall be marked as main roads.

The sign "End of Main Road" (3.04) indicates that the road loses its priority status and that the right-of-way rule prescribed by law (Art. 36, para. 2, Road Traffic Act) applies again at intersections.

The "End of Main Road" sign shall be placed on the right side of the roadway, and on roads with multiple lanes in the same direction, generally on both the right and left sides of the road, shortly before the intersection. Accompanied by the "Distance Plate" (5.01), it shall also be placed as an advance sign, between 150 and 250 meters from the intersection outside localities and approximately 50 meters within localities.

The "Intersection with a Non-Priority Road" sign (3.05) informs drivers traveling on secondary roads that they will have the right of way at the next intersection. When multiple intersections occur at short distances, the length of the section where the driver has priority may be indicated by the supplementary sign "Length of the Section" (5.03).

Within localities, it is not necessary to place the "Intersection with a Non-Priority Road" sign where the driver is able to notice in time that vehicles emerging from the right do not have the right of way, such as in cases where there is a "Stop" sign (3.01) or a "Yield" sign (3.02), a stop line (6.10), or a waiting line (6.13).

The "Intersection with Right-of-Way Priority" sign (3.06) indicates, on secondary roads, an intersection where the right-of-way priority prescribed by law applies (Art. 36, para. 2, LCR).

The "Intersection with Right-of-Way Priority" sign will only be placed: a. if the driver does not have the possibility to see in time the road emerging from the right; b. if an intersection where the legally prescribed right-of-way priority applies follows several intersections equipped with the "Intersection with Non-Priority Road" sign (3.05).

The sign "Give way to oncoming traffic" (3.09) requires the driver traveling in the direction of the red arrow to yield to oncoming traffic where the road narrows. This obligation does not apply to vehicles whose wheels are positioned one behind the other, where drivers can determine they have enough room to safely pass oncoming vehicles. At the opposite end of the narrowed passage, the sign "Priority over oncoming vehicles" (3.10) should be placed.

The sign "Priority over oncoming vehicles" (3.10) indicates to the driver traveling in the direction of the white arrow that they may continue driving where the road narrows, and that vehicles with side-by-side wheels must wait until the passage is clear. If these vehicles are already engaged in the narrowed passage, it is incumbent upon them to wait.

Indication signs that involve rules of conduct are rectangular or square. Generally, they feature either a white symbol on a blue background, or a symbol depicted in a white median field on a blue background.

Subject to exceptional provisions applicable to certain signs, they will be placed at the beginning of the route to which the indication pertains. If necessary, the length of the section to which the indication relates will be announced on the supplementary plate "Length of the Section" (5.03).

If advance signs are necessary or prescribed, they will be placed, with a "Distance Plate" (5.01), before the beginning of the section to which the indication pertains, as follows: a. in localities at least 50 m; b. outside localities at least 150 m; c. on highways and semi-highways at least 500 m.

The signs "Motorways" (4.01) and "Semi-Motorway" (4.03) designate roads reserved for motor vehicle traffic (Art. 1, Para. 3, OCR), to which the rules specifically provided for motorway and semi-motorway traffic apply (Art. 35 and 36 OCR); these signs remove all previously indicated restrictions. The signs "End of Motorway" (4.02) and "End of Semi-Motorway" (4.04) indicate that the general traffic rules are applicable again. Art. 85 applies to the placement of the signs.

The sign "Mountain Postal Route" (4.05) designates roads on which drivers must observe, when it is difficult to pass or overtake, the signs and indications given by drivers of public vehicles in line traffic (Art. 38, Para. 3, OCR). The sign "End of Mountain Postal Route" (4.06) is placed where this obligation ends. ...

The sign "Tunnel" (4.07) designates a section that passes through a tunnel and to which the rules specifically provided for traffic in tunnels apply (Art. 39 OCR and Art. 13, Para. 3 SDR). The sign will be placed at the entrance of the tunnel and, additionally, as an advance sign (Art. 44, Para. 3). On motorways and semi-motorways, the name of the tunnel will be indicated near the sign placed at the entrance of said structure.

The sign "One-way" (4.08) indicates roads on which vehicles may only travel in the direction shown (Art. 37 OCR). At the other end of the road, the sign "No Entry" (2.02) will be placed.

The sign "One-way with Restricted Traffic in Opposite Direction" designates one-way streets on which certain types of vehicles are allowed to travel in the opposite direction; a symbol or an inscription indicates the type of vehicle in question (e.g., "One-way with Cyclist Traffic in Opposite Direction"; 4.08.1).

The sign "Dead End" (4.09) designates roads with no exit. If a road ends with a pedestrian path or a cycle track, the sign may be supplemented with appropriate symbols ("Dead End with Exceptions"; 4.09.1).

The sign "Water Protection Zone" (4.10) designates an area where a driver transporting a load that could harm the water must exercise particular caution. The length of the section where increased caution is required will be indicated by the supplementary plaque "Length of Section" (5.03).

The sign "Location of a Pedestrian Crossing" (4.11) highlights the presence of a pedestrian crossing (Art. 77). It shall always be placed in front of crossings located outside urban areas and, within urban areas, in front of those that are unexpected or difficult to see. A single visible sign for both directions of traffic is sufficient if placed on the refuge of roads equipped with one, or at the edge of the roadway on narrow secondary roads. Art. 11 applies to advance signaling using the "Pedestrian Crossing" sign (1.22).

The signs "Pedestrian Underpass" (4.12) and "Pedestrian Footbridge" (4.13) shall be placed before the passages arranged below and above the roadway, which pedestrians must use (Art. 47, para. 1, OCR) but which are prohibited for vehicles. The symbols may be laterally inverted depending on the site configuration. When not placed near the passage arranged below or above the roadway, the sign must indicate the direction and distance to the underpass or footbridge.

The sign "Hospital" (4.14) indicates that a hospital, convalescent home, or similar facility is nearby. The driver must proceed with particular care.

The sign "Passing Place" (4.15) designates places where drivers of slow vehicles must pull over to allow faster vehicles to overtake them (Art. 10, para. 3, OCR); voluntary stopping and parking are prohibited.

The sign "Breakdown Parking Area" (4.16) placed on highways and semi-highways without an emergency lane designates areas for stops compelled by circumstances (Art. 36, para. 3, OCR); voluntary stopping and parking are prohibited there. The sign will be installed near the parking area and, additionally, as an advance warning sign (Art. 44, para. 3).

The sign "Escape Lane" (4.24) designates a lane marked with a red and white checkerboard, followed by a stopping bed where drivers can bring their vehicle to a halt in the event of a braking system failure.

Parking areas are indicated by the signs "Parking Allowed" (4.17), "Parking with Parking Disc" (4.18), or "Paid Parking" (4.20).

The parking regulations and restrictions concerning the parking duration are displayed on an additional plaque.

When parking is time-limited, vehicles must leave the parking area no later than the moment the authorized parking duration expires, unless it is permitted, according to the instructions on the parking meter, to pay an additional fee before the end of the authorized time.

The restriction of the authorization to park to specific user groups or certain categories of vehicles is indicated in the blue field of the parking sign or on an additional plaque. Alternatively, it may also be indicated by a mark on the parking space. The restriction of the authorization to park by means of a mark is governed by Art. 79, para. 4.

If parking areas are specifically intended for drivers who wish to use public transportation, the type of public transportation may be indicated in full letters or symbols in the blue field of the parking sign (4.25).

If the distance and direction to a parking area need to be indicated, the corresponding information will be displayed in the blue field of the "Parking Allowed" sign (4.17) or on an additional plaque.

If the area where parking is permitted is covered, the blue field of the parking sign can be supplemented with a stylized roof (e.g., "Covered Parking" sign, 4.21).

The sign "Parking with Parking Disc" (4.18) indicates parking areas where a parking disc according to Annex 3, Sec. 1, must be used. These parking areas can be used by motor vehicles, other multi-track motor vehicles, motorcycles with sidecars, and other vehicles of similar dimensions, excluding multi-track mopeds.

The sign has the following meaning: a. without additional indication of a time limitation (blue zone): on working days, the parking duration is limited for vehicles between 8 a.m. and 7 p.m. If the limitation is also valid on Sundays and public holidays, this must be indicated on an additional plate. Parking durations are regulated by the parking disc provided in Annex 3, Sec. 1; b. with additional indication of a time limitation: vehicles may be parked for a maximum duration as specified on the additional plate. The limited parking time must be at least half an hour.

Anyone parking their vehicle in a parking area marked in accordance with para. 1 must set the arrow on their parking disc to the mark following their actual time of arrival. The indications given by the disc must not be altered before the vehicle departs.

The parking disc must be placed visibly on the vehicle, behind the windshield if it is a car.

The sign "Paid Parking" (4.20) designates parking lots where vehicles can only be parked upon payment of a fee and in accordance with the instructions displayed on the parking meters. These instructions may require the payment of an additional fee before the authorized time expires.

The indication "Multiple-Bay Meter" on an additional plate attached to the "Paid Parking" sign (4.20) indicates that a parking meter is intended for several parking spaces. If this device issues a ticket upon payment of the parking fee, the ticket must be placed visibly behind the windshield of the motor vehicle.

On place name signs, direction signs, advance direction signs, and preselection signs (Art. 50 to 53), the names of localities shall be inscribed in the language spoken in the announced localities; with regard to municipalities where two languages are spoken, the language spoken by the majority of the inhabitants must be chosen. If the name of a locality is written differently in two languages, the front of the place name sign will carry both spellings, provided that the linguistic minority represents at least 30% of the inhabitants.

Direction signs, advance direction signs, and preselection signs will primarily mention localities; if necessary, they can announce important local destinations (e.g., the train station, the center, the hospital). Art. 54, para. 4 applies to “Company” direction signs, and para. 9 of the same article applies to tourist signage and direction signs for hotels. The symbols used on the direction signs, as well as their meanings, are listed in Annex 2, sec. 5.

The provisions of Art. 84 to 91 apply to direction signs, advance direction signs, and preselection signs placed on highways and expressways.

The direction signs, advance direction signs, and preselection signs on highways and expressways may only mention the localities designated by the DETEC.

Locality signs with white lettering on a blue background ("Start of Locality on Main Road"; 4.27; "End of Locality on Main Road"; 4.28) are placed on main roads. Locality signs with black lettering on a white background ("Start of Locality on Secondary Road"; 4.29; "End of Locality on Secondary Road"; 4.30) are placed on secondary roads. There are no locality signs on motorways and expressways.

The front of the locality sign functions as the signal "Start of Locality on Main Road" or "Start of Locality on Secondary Road"; it displays the name of the locality and, below it, when the locality is situated in the border area between two cantons, the abbreviation of the canton on whose territory the sign is located.

The reverse of the locality sign functions as the signal "End of Locality on Main Road" or "End of Locality on Secondary Road"; it displays, in the upper space, the name of the next agglomeration and, in the lower space, the name of the nearest destination center as well as its distance. If a bifurcation occurs after the sign, two destination centers may be indicated.

The signals "Start of Locality on Main Road" or "Start of Locality on Secondary Road" will be placed where the zone of dispersed dwellings begins; they must not be placed after the signal indicating the beginning of the general speed limit within localities (Art. 22, para. 3).

Where two localities meet, the locality sign represents the signal "Start of Locality on Main Road" or "Start of Locality on Secondary Road" on both sides.

To designate mountain passes, locality signs should be used that display, on both sides, the name of the pass, completed if necessary by the words "Summit of the Pass" and the indication of altitude.

Direction indicators with white inscriptions on a green background show the route to follow to reach motorways and semi-motorways ("Direction indicator for motorways and semi-motorways"; 4.31). Direction indicators with white inscriptions on a blue background indicate that the announced destination can be reached primarily via main roads ("Direction indicator for main roads"; 4.32). Direction indicators with black inscriptions on a white background indicate that the announced destination can be reached primarily via secondary roads ("Direction indicator for secondary roads"; 4.33).

Multiple localities situated in the same direction will be mentioned on the same arm of the indicator; an arm can include a maximum of three lines.

It is possible to add corresponding symbols to the names of localities equipped with a civil airfield or a vehicle loading dock on the rail or a ferry, according to annex 2, ch. 5.

When a region is served by only one motorway or semi-motorway, or a bypass motorway, the direction indicators for motorways and semi-motorways can be replaced, where feeder roads intersect with secondary roads, by green background direction indicators that carry the white symbol of the "Motorway" (4.01) or "Semi-motorway" (4.03) signals but do not announce a destination.

When local conditions require it, a "Table-shaped direction indicator" (4.35) can be installed. At intersections, it can be mounted above the roadway and combined, notably, with a light signal installation. The first paragraph applies concerning the color of each section of the table.

...

Advanced direction indicators with white inscriptions on a blue background will be placed on main roads and on secondary roads connecting to main roads ("Advanced Direction Indicator on Main Road"; 4.36). Advanced direction indicators with black inscriptions on a white background will be placed on significant secondary roads ("Advanced Direction Indicator on Secondary Road"; 4.37). Destinations accessible by a highway or a semi-highway are indicated on a green field, those accessible mainly by main roads on a blue background or blue field, and those accessible mainly by secondary roads on a white background or white field.

Outside localities, advanced direction indicators will be placed between 150 and 250 meters from the intersection; within localities, between 20 and 100 meters, but no later than at the start of the section used for lane pre-selection.

A single advanced direction indicator may suffice for several intersections located less than 300 meters from each other.

The direction of the road will be represented by lines corresponding to the layout of the roadways after the intersection. Before roundabouts, the "Advanced Direction Indicator for Roundabout" (4.54) signal may be used.

The "Advanced Direction Indicator with Lane Allocation on Main Road" (4.38) or the "Advanced Direction Indicator with Lane Allocation on Secondary Road" (4.39) can be placed at the beginning of a section used for lane pre-selection. Each traffic lane will be indicated by a separate arrow; the first paragraph applies regarding the color and arrangement of the fields.

On the advanced direction indicators, it is possible to announce traffic restrictions valid for one of the indicated sections (e.g., width or weight restrictions) by reproducing the corresponding regulatory signal ("Advanced Direction Indicator Announcing Restrictions"; 4.40).

The silhouette depicted on the "Aircraft" signal (1.28) may be added to the names of localities with a civil aerodrome.

Preselection panels placed above the roadway, prior to intersections of multi-lane roads, indicate the specific destination to which each lane leads ("Preselection Panel above a Lane on a Main Road"; 4.41, and "Preselection Panel above a Lane on a Secondary Road"; 4.42). The arrow pointing downward indicates the center of the lane. The provisions governing advanced direction indicators (Art. 52, para. 1) apply to the color of the fields, and those of Art. 56 to the method of numbering main roads and major European transit routes.

...

"The direction indicator for certain types of vehicles" (4.45) shows the direction that vehicles represented by symbols should take (e.g., the direction indicator for trucks). "The advanced direction indicator for certain types of vehicles" (4.23) will be placed, if needed, as an advanced signal.

The "Parking Space" direction indicator (4.46) shows the direction to locations where parking is permitted. When parking is reserved for certain categories of vehicles, the silhouettes corresponding to these vehicles will be added to the direction indicator.

The "Parking with Access to Public Transport" direction indicator (4.46.1) indicates the direction of such a parking location. The type of public transport can be indicated in full words or in the form of symbols.

The "Campsite" (4.47) and "Caravan Grounds" (4.48) direction indicators show the direction of spaces reserved for tents or caravans; if applicable, the symbols of these two indicators can be reproduced on a panel.

The "Business" direction indicator (4.49) shows the way to reach industrial, artisanal, or commercial businesses, exhibitions, etc. It indicates the route to be taken to reach frequently visited places that are difficult to locate without direction indicators and are off major transit roads (art. 110, para. 1) or significant secondary roads.

...

When turning left at the next intersection is prohibited, the "Traffic Guidance" panel (4.52) indicates to the driver the detour to make in order to still be able to reach the left.

...

The "Side Road with Danger or Restriction" panel (4.55), which features an appropriate danger or prescription signal for the circumstances, may be placed shortly before an intersection when immediately after the intersection the side road presents a dangerous spot or is subject to a traffic restriction.

The DETEC issues instructions regarding tourist signage and direction indicators for hotels.

Direction indicators displaying white inscriptions on a red background are used for cycles, mountain bikes, and devices assimilated to vehicles.

The direction indicators "Route for Cyclists" (4.50.1) and "Route for Devices Assimilated to Vehicles" (4.50.4) designate routes that, due to their location and prevailing traffic conditions, are particularly suitable for the circulation of cycles and devices assimilated to vehicles.

The direction indicator "Route for Mountain Bikes" (4.50.3) designates routes that are particularly suitable for mountain bike use and obliges users to display special consideration for pedestrians; when the situation requires, cyclists must warn them and, if necessary, stop.

When it is not necessary to indicate destinations, direction indicators 4.50.1, 4.50.3, and 4.50.4 may be replaced by a "Direction Indicator without Destination" (4.51.1), an "Advanced Direction Indicator without Destination" (4.51.2), or a "Confirmation Plate" (4.51.3).

When local conditions require, direction indicators in the form of a table may be used. Direction indicator 4.50.5 is employed when addressing a single user group and direction indicator 4.50.6 when addressing multiple groups.

May also be included on the direction indicators: a. the distance to the indicated destination; b. additional information such as the route number and name in a signal field.

The corresponding end-of-route panel (4.51.4) may be placed at the location where a route suitable for the circulation of cycles, mountain bikes, or devices assimilated to vehicles ends.

Traffic detours are announced using advance direction indicators representing the section closed to traffic as well as the detour route with the main localities it passes through ("Advance Direction Indicator Announcing a Detour"; 4.53).

The "Detour Direction Indicators" (4.34), with an orange background, shall be used along the detour route; for relatively short detours, the destination may be omitted (4.34.1).

Detour routes for cyclists and moped riders can be announced using the signals referred to in Art. 54 a, with an orange background. These signals can also be used to announce detour routes for pedestrians if they bear the pedestrian symbol. The symbols for bicycles and pedestrians can be depicted together on the same signal.

Destinations accessible via the detour route may be indicated in black letters on an orange background on all panels used for direction indication.

The "Numbered Plaques for European Roads" (4.56) bear the letter "E" in white color and a number of the same color on a green background; they indicate sections of the major European transit road network. The numbers are based on the ordinance of 18 December 1991 regarding major transit roads; their appearance and placement must comply with the instructions of the DETEC.

The "Numbered Plaques for Motorways and Semi-Motorways" (4.58) have a white number on a red background; they designate the network of motorways and semi-motorways. The DETEC establishes the basic network and issues instructions regarding the appearance and placement of numbered plaques.

The "Numbered Plaques for Main Roads" (4.57) have a white number on a blue background; they designate the most important main roads. The numbers are based on the ordinance of 18 December 1991 regarding major transit roads; their appearance and placement must comply with the instructions of the DETEC.

The "Numbered Plaque for Junctions" (4.59) and the "Numbered Plaque for Branches" (4.59.1) feature a black symbol and a black number on a white background; they indicate junctions or branches on motorways and semi-motorways. The DETEC determines the numbers in agreement with the cantons and issues instructions regarding the appearance and placement of numbered plaques.

Signs carrying information are rectangular or square. As a rule, they have a blue background with a black symbol on a white field. Subject to any exemptions applicable to certain signs, these signs shall be placed at the entrance of a facility, a building, at the location where the advertised service is provided, or at the location where the information given takes effect. If advance signs are necessary or prescribed, they shall be placed, with a “Distance Plate” (5.01), before the beginning of the section to which the indication relates, as follows: a. in urban areas, at least 50 m; b. outside of urban areas, at least 150 m; c. on highways and semi-highways, in accordance with Art. 89.

The signal "Road Conditions" (4.75) announces the condition of passes and roads leading to winter sports resorts, etc., which are temporarily impassable or which can only be accessed with snow chains. As an advance signal, it is necessary to use the "Notice on Road Conditions" (4.76) signal.

The "Road Conditions" signal shall be placed at the beginning of the affected section; the "Notice on Road Conditions" signal shall be installed on access roads leading to such sections, sufficiently early to allow drivers to take a detour.

The signals indicate the name of the pass or the destination; they bear, either beside or below, indications concerning road conditions. When intermediate destinations are announced, the information on road conditions is valid only up to the destination whose name appears immediately beside or above this indication.

On the signals, colors have the following meanings: a. red field: road closed; b. green field: road open; c. white field bearing the symbol of the "Snow Chains Required" signal (2.48): metal snow chains or similar devices made of another material and authorized by the FEDRO are mandatory (Art. 29); d. white field bearing the symbol of the "Slippery Road" signal (1.05) and supplementary plaque "Icy Surface" (5.13): slippery snow or icy road surface.

When these signals are used to announce detours that extend over a large region, the background of the signal shall be orange and the inscription shall be in black.

The signal "Arrangement of Traffic Lanes" (4.77) indicates the layout, the number of lanes, and, where applicable, the decrease or increase in this number. The arrows show the traffic lanes and are black in color; the background of the sign is white. When the signage is temporary, the symbol of signal 4.77 can be reproduced on a foldable triangular sign of white color.

The signal "Opening of the Emergency Lane" (4.77.2) indicates that it is permitted to use the emergency lane.

When a regulation or a warning of danger is valid only for certain lanes, the relevant signal will be displayed in the middle of the arrow representing the lane in question ("Arrangement of Traffic Lanes Indicating Restrictions"; 4.77.1).

Art. 89, para. 2, applies to the placement of the "Arrangement of Traffic Lanes" signal on highways and semi-highways.

Foreign drivers are informed of the general speed limits in effect in Switzerland by the sign "Information on General Speed Limits" (4.93) placed near customs posts.

The signs "Campsite" (4.79), "Caravan Site" (4.80), "Telephone" (4.81), "First Aid" (4.82), "Petrol Station" (4.84), "Hotel-Motel" (4.85), "Restaurant" (4.86), "Refreshments" (4.87), "Information Post" (4.88), "Youth Hostel" (4.89), "Radio Traffic Report" (4.90), "Religious Service" (4.91), and "Fire Extinguisher" (4.92) indicate the respective services, facilities, or buildings.

If applicable, the symbols for the "Campsite" and "Caravan Site" signs may appear in the white central field of a panel.

Regarding the "Telephone" sign, the letters SOS must be added on the blue background, beneath the symbol, when it concerns an emergency call installation.

The signs "Hotel-Motel", "Restaurant", and "Refreshments" will only be placed where road users would not easily see the respective facilities or buildings or would find them with difficulty; the name of the establishments must not appear on these signs.

The "Radio Traffic Report" sign indicates the broadcaster transmitting a national program and the frequency on which drivers can receive traffic information. On roads other than motorways and semi-motorways (art. 89, para. 3), it will be placed only where the frequency range changes.

Art. 89, paras. 1 and 3, apply to the placement of signs on motorways and semi-motorways.

The "Direction and Distance to the Nearest Emergency Exit" sign (4.94) provides information about the nearest emergency exit; in tunnels, it is placed on the wall at least every 50 meters at a height of 1 to 1.5 meters above the road surface. The "Emergency Exit" sign (4.95) indicates the location of an emergency exit and is placed in its immediate proximity.

The sign "Vehicles Equipped with an Automation System" (4.91 bis) is placed at all entrances to parking lots that permit authorized automated parking.

Additional information regarding a signal is displayed on a supplementary plaque in a rectangular shape. The background is white, and the inscriptions and, if applicable, the symbols are black. In the case of matrix signals, the background may be black and the symbol white. Generally, supplementary plaques should be placed under the signals; Art. 101, para. 7, is reserved. When it comes to indication signals (chap. 5), with a blue background, simple additional information (e.g., about distance or direction) is provided, if necessary, in white characters or by means of a white symbol. The directives on the supplementary plaques are as imperative as the signals themselves.

The "Distance Plate" (5.01) is used to indicate the distance to a hazardous location or a location where a prescription applies. To signal both the distance and direction, the "Distance and Direction Plate" (5.02) is used.

The length of sections that are hazardous, subject to a prescription, or where an indication must be observed, will be indicated by the supplementary plate "Section Length" (5.03).

Repetition signals will be characterized by the "Reminder Plate" (5.04). The start and end of a section equipped with signals concerning the stopping or parking of vehicles will be announced respectively by the "Start of Prescription Plate" (5.05) and by the "End of Prescription Plate" (5.06).

The "Direction Plate" (5.07), featuring an arrow pointing left or right, indicates the location which is hazardous, where a prescription applies, or where an indication must be observed. It is used particularly: a. under the signals "Cycle Path" (2.60), "Pedestrian Path" (2.61), and "Equestrian Path" (2.62) when such a path located on the other side of the roadway must be used (art. 33); b. under the signals "No Parking" (2.50) and "Parking Allowed" (4.17) to indicate the direction in which a space is forbidden or reserved for parking.

The scope of application of signs may be materialized using a supplementary plate. A supplementary plate containing: a. a corresponding symbol or inscription signifies that the sign to which the plate is added applies only to the type of transport represented; articles 15, para. 1, and 46, para. 2, are reserved; b. the word "Except" or "Authorized" in relation to an inscription or symbol means that the sign to which the plate is added does not apply to the corresponding type of transport.

The "Cycle" symbol (5.31) or a corresponding inscription on a supplementary plate applies to bicycles and mopeds.

The "Moped" symbol (5.30) or a corresponding inscription on a supplementary plate applies to heavy and fast mopeds.

The "Cargo Bike" symbol (5.31.1) on a supplementary plate applies to bicycles and mopeds intended for transporting children, passengers or goods, as well as bicycles and mopeds with trailers.

The symbols used on supplementary plates and their designations are listed in Annex 2, ch. 5.

When added to the "Pedestrian Path" sign (2.61), the supplementary plate "authorized" allows cyclists and moped riders to use the pedestrian path. This signage is exceptionally permitted on sidewalks, especially to ensure safety on school routes, provided that the sidewalk is not heavily trafficked and that there is relatively dense traffic on the road. The provisions regarding shared use referred to in Art. 33, para. 4 apply.

When added to the pedestrian paths mentioned in para. 1, the supplementary plate "prohibited" prohibits heavy moped and fast moped riders from using the indicated path.

When added to the signs "Bicycle Lane" (2.60), "Bicycle Lane and Pedestrian Path, with shared traffic area" (2.63) and "Bicycle Lane and Pedestrian Path without shared traffic area" (2.63.1), the supplementary plate "optional" exempts heavy moped and fast moped riders from the obligation to use the indicated path.

When added to the signs "Bicycle Lane" (2.60), "Bicycle Lane and Pedestrian Path, with shared traffic area" (2.63), and "Bicycle Lane and Pedestrian Path without shared traffic area" (2.63.1), the supplementary plate "prohibited" prohibits heavy moped and fast moped riders from using the indicated path. This supplementary plate can only be used in exceptional cases, especially when pedestrian traffic is high and space is lacking.

If necessary, the end of the authorizations referred to in paras. 1 and 3 and the prohibition referred to in para. 4 can be indicated by a supplementary plate on which the indications are crossed out by three black diagonal lines starting from the bottom left to the top right.

When added to the signs "Stop" (3.01), "Yield" (3.02), and "Main Road" (3.03), the additional panel "Direction of the Main Road" (5.09) indicates the route of a main road changing direction. In conjunction with "Stop" and "Yield" signs, it informs drivers traveling on a road whose priority is removed that they must yield to vehicles traveling on the main road or those leaving it. The broad line represents the main road. Temporary exemptions to the prohibition of stopping or parking (2.49; 2.50) will be indicated by the panels "Exemption from stopping prohibition" (5.10) and "Exemption from parking prohibition" (5.11). When added to the signs "Barriers" (1.15) and "Level crossing without barriers" (1.16), the panel "Flashing lights" (5.12) denotes level crossings equipped with flashing light signals. The panel "Icy Road" (5.13) warns drivers that the road is icy or covered with slippery snow. It will notably be added to the sign "Slippery Road" (1.05); it must be removed or covered as soon as there is no longer a reasonable expectation of slippery snow or ice formation. To reserve certain parking spaces for persons with reduced mobility, the additional panel "Disabled" (5.14) must be added near the relevant spaces to the sign "Parking Authorized" (4.17); only those who are disabled or accompanying a person with reduced mobility may park in these places. The "Parking Card for Disabled Persons" (annex 3, ch. 2) must be placed visibly behind the windshield. When added to the sign "Narrow Roadway" (1.07), the panel "Width of Roadway" (5.15) indicates the width of the road at its narrowest point. The panel "Gunfire Noise" (5.16), added to the sign "Other Dangers" (1.30), warns drivers of unexpected noise caused by artillery pieces. ... The panel "Customs Passage with Customs Clearance at Sight" (5.54), added to the sign "General Prohibition of Traffic in Both Directions" (2.01), indicates that this route is to be used only by drivers with customs clearance at sight. An additional panel added to the sign "No Truck Traffic" (2.07), with the mention "except" and the symbol "Traffic S" (5.55), indicates that vehicles and vehicle combinations bearing the distinctive emblem as per annex 4 of the OETV are not subject to the restriction. The symbol "Hospital with Emergency Service" (5.56) indicates an acute care hospital with an emergency service operating 24 hours a day. The additional panel with the symbol "Emergency Phone" (5.57) or with the symbol "Fire Extinguisher" (5.58), added to the sign "Stopping Place for Vehicles in Breakdown" (4.16), indicates that the stopping place is equipped with the mentioned facilities. The panel consisting of the symbol "Charging Station" (5.42), added to the signs "Parking Authorized" (4.17), "Parking with Parking Disc" (4.18), and "Parking against Payment" (4.20), indicates that the area in question can only be used for charging electric-powered vehicles. The panel "authorized," added to the sign "Parking Prohibited" (2.50), indicates that the area in question can be used for charging electric-powered vehicles. The panel marked with "Except" and the symbol "Carpooling" (5.43), added to the signs "General Prohibition of Traffic in Both Directions" (2.01), "Traffic Prohibited for Motor Vehicles" (2.03), and "Lane Reserved for Buses" (2.64), indicates that the road or lane in question may be used by vehicles carrying at least the number of persons stated on the symbol. The additional panel with the symbol "Carpooling" (5.43), added to the signs "Parking Authorized" (4.17), "Parking with Parking Disc" (4.18), and "Parking against Payment" (4.20), indicates that the area in question may only be used by vehicles carrying, upon arrival, at least the number of persons indicated on the symbol.

If traffic is regulated by the police, road users shall wait for the officer to signal them, unless they are in a moving queue that the officer does not stop. The meaning of the hand signals is as follows: a. arm raised: stop before the intersection for drivers coming from all directions; b. arm extended to the side: stop for all drivers coming from behind; c. both arms extended to the side: stop for drivers coming from the front and behind; d. forearm signaling drivers to move forward: clear to proceed in the indicated direction; e. repeated forearm movements, up and down: slow down.

Special hand signals intended for pedestrians and public vehicles in line traffic are reserved.

To make hand signals more visible, the police may use a white baton and, at night or when atmospheric conditions require it, a white or yellow luminous baton.

Hand signals may also be used in the performance of other police duties (e.g., traffic checks). A stop will be ordered, at night or when atmospheric conditions require it, using a red luminous baton or a red luminous paddle; the same means may be used to invite drivers to continue their route. The paddle may bear the inscription "Police."

A stop may also be ordered by: a. school patrols, company personnel, and cadets in charge of traffic regulation, using a reflective paddle shaped and resembling the sign "General prohibition of traffic in both directions" (2.01) and, at night or when atmospheric conditions require it, using a red luminous baton or a red luminous paddle; b. operating personnel near railway tracks, using a red or red and white flag at night or when atmospheric conditions require it, using a red light; c. road construction site personnel, using a reflective paddle shaped and resembling the signs "No entry" (2.02) and "General prohibition of traffic in both directions" (2.01) or using a red or red and white flag. Article 80, para. 4, applies to alternating-face paddles used near construction sites.

Road users are required to comply with the signs and instructions given: a. by uniformed police officers and auxiliary police; b. by military personnel tasked with directing traffic and uniformed staff of fire services and civil defense; c. by school patrols, company employees, and cadets assigned to direct traffic when they wear the insignia of their function; d. by staff at road construction sites; e. by customs officers near customs offices and, for customs controls, in the area close to the border, as well as by duly identified sales and control personnel employed by customs offices in the execution of the March 19, 2010, law on highway vignettes; f. by operating personnel near railway tracks; g. by drivers of public vehicles in line traffic on mountain postal roads (Art. 38, para. 3, OCR); h. by members of private traffic services equipped with distinctive signs; i. by personnel of convoy vehicles indicated as special vehicles and special transports.

Signs and instructions given by other persons must be observed when they are intended to prevent a danger or to regulate traffic in a difficult situation.

To have traffic regulated by school patrols, by company employees or cadets (para. 1, letter c), by private traffic services (para. 1, letter h), or by personnel of convoy vehicles indicated (para. 1, letter i), it is necessary to obtain authorization from the cantonal police authority. This authority gives the necessary orders; it may delegate its competence to local police authorities.

Light signals take precedence over the general right-of-way rules, priority signals, and road markings.

The red light means "Stop." When the outlines of an arrow appear in black within the red light, the order to stop only applies in the indicated direction. The flashing red light is used only near railway crossings (Art. 93, para. 2).

The green light means the road is clear. Those making turns must yield priority to oncoming vehicles (Art. 36, para. 3, LCR) and to pedestrians or users of devices equivalent to vehicles engaged on the crosswalk (Art. 6, para. 2, OCR).

Green arrows allow movement in the indicated direction. When a flashing yellow light appears next to these arrows simultaneously, vehicles making turns must yield priority to oncoming vehicles (Art. 36, para. 3, LCR) and to pedestrians or users of devices equivalent to vehicles engaged on the crosswalk (Art. 6, para. 2, OCR).

The yellow light means: a. if it follows the green light: stop for vehicles that can still stop before the intersection; b. if it appears simultaneously with the red light: prepare to depart and wait for the green light to indicate that the way is clear.

When the outlines of an arrow appear in black within the yellow light, this light only applies in the indicated direction.

The flashing yellow light (Art. 70, para. 1) urges drivers to exercise special caution.

Lights showing the silhouette of a pedestrian are intended for pedestrians. They may only enter the roadway or cross the path if the pedestrian light is green. If it begins to flash or an intermediate yellow light appears, or the red light turns on without transition, pedestrians already on the roadway or path must leave it without delay.

Lights showing the silhouette of a bicycle are intended for cyclists and moped riders. The meaning of these lights is governed by paras. 1 to 4.

Black arrows on supplementary plates placed under the light signals mean that these signals only apply in the indicated direction.

...

White lights arranged in a particular manner (Art. 70, para. 8) are intended exclusively for drivers of public line traffic vehicles; they are mandatory for these drivers.

To regulate traffic on multi-lane roads and to temporarily close certain lanes to traffic or to temporarily open the emergency lane, the following system of light signals placed above the roadway must be used ("Light Signal System for Temporary Lane Regulation"; 2.65): a. the green arrows directed vertically downward signify that traffic is permitted on the lane they indicate; they must be extinguished as soon as two red diagonal bars in the shape of a cross or flashing yellow arrows light up in the same place; b. the flashing yellow arrows, directed obliquely downward, mean that the driver must, as soon as possible, leave the current lane and proceed in the indicated direction; c. two red diagonal bars in the shape of a cross mean that the corresponding lane is closed to traffic; the driver must leave this lane and continue on a lane where traffic is permitted by a green arrow.

The "Light Signals" panel (1.27) can be used to indicate an approach to a "Light Signal System for Temporary Lane Closures."

If the signal "Authorization to Turn Right for Cyclists" (5.18) is placed next to the red light, cyclists and moped drivers may turn right when the light is red. The combination of the red light and the signal is equivalent to a "Yield" (Art. 36, para. 2) for those authorized to turn right.

The signal "Authorization to Turn Right for Cyclists" (5.18) will only be placed next to the red light if road safety is ensured. The relevant traffic lane must have a cycle lane as well as a yellow stop line for cyclists after the white stop line intended for other drivers. A cycle lane is not necessary: a. if there is a separate lane for turning right or if other vehicles are not permitted to turn right, and b. if the traffic lane is sufficiently wide.

The flashing yellow light used as a warning for road users (Art. 68, para. 6) is only authorized in the following cases: a. in conjunction with a green arrow (Art. 68, para. 3); b. when light signal installations are switched off; c. near construction sites; d. before dangerous obstacles located on the roadway; e. near pedestrian crossings (Art. 77), at island terminals, etc.; f. on the side of highways during accidents, traffic jams, fog, ice, and other similar hazards; g. ...

The rotating yellow light is prohibited.

Red lights used alone, red arrows, light installations without red lights, as well as flashing signal lights, are not permitted, except near level crossings (Art. 93). Green lights used alone are only authorized as repeat signals.

Light installations with red and yellow lights, but without green lights, may be used only in exceptional cases, particularly near fire service garages, near construction sites, near terminal loops of public vehicles in line traffic, near airfields, at the entrance and inside tunnels, and near level crossings.

Light installations with red and green lights, but without yellow lights, may be used only in specific cases and solely within the framework of managing highway and semi-highway ramps. The green light that flashes when the installation is activated indicates that the light will soon turn red.

When lights are placed one above the other in light installations, the red light will be at the top, the green light at the bottom, and, if applicable, the yellow light in between. The lights will have a round shape.

When lights are placed side by side in light installations fixed above the roadway, the red light will be on the left, the green light on the right, and, if applicable, the yellow light in the middle. The lights will have a round shape.

Lights intended for pedestrians bear the silhouette of a pedestrian (Art. 68, para. 7); they may be rectangular in shape. Lights intended for cyclists and moped riders bear the silhouette of a cycle (Art. 68, para. 8), if they are also visible to other vehicle drivers; when combined with lights intended for pedestrians, they may be rectangular in shape.

Only white lights arranged in a particular manner (Art. 69, para. 2) may be used as special signals intended for public vehicle drivers in line traffic.

The light signals, except repeat signals, must be placed on a rectangular black panel with a white border; this panel is not necessary when any glare from the sun or other light sources is excluded.

Traffic lights are installed on the right edge of the road. They can be repeated above the relevant lane, on the left side, or on the opposite side of the intersection.

The lights may be placed: a. on the left side exclusively for the outer left lane, when the road comprises multiple lanes in the same direction; b. exclusively above the roadway if considered appropriate; c. in special cases, for example near rail tracks on dedicated paths running alongside the road, doubled for a single lane to regulate diverse traffic directions; for this purpose, the lane must be at least 4.50 m wide, and the lights must be clearly assigned to the vehicle flows; d. on the opposite side of the intersection if they are intended exclusively for cyclists and moped riders.

The lower height of the edge of the lights is: a. 2.35 m to 3.50 m at the roadside; for lights that concern exclusively pedestrians, cyclists, and moped riders, it may be lower; b. 4.50 m to 5.50 m above the roadway; it may be higher where there are public transport contact lines.

Light signals must prevent the meeting of vehicles coming from different directions, except those turning left with oncoming vehicles and those involving cyclists or moped riders turning right according to Art. 69a, para. 1, with priority recipients. When green arrows give the right of way and there is no flashing yellow light (Art. 68, para. 3), all meeting is also excluded between vehicles turning into another street and pedestrians crossing it, and between vehicles turning left and those coming from the opposite direction.

Vehicles coming from the right are allowed to take the same direction as vehicles going straight only if each of these two groups of vehicles has a dedicated lane after the intersection. Exceptions are bicycles and mopeds coming from the right according to Art. 69a, para. 1.

The sequence of light signal colors is as follows: green – yellow – red – red and simultaneously yellow – green; Arts. 68, para. 7, 69, para. 3, 70, para. 4 and 4bis, are reserved. The red light must not be on at the same time as the green light. The red and yellow lights illuminated at the same time must only turn off when the green light comes on.

Light signal installations can be equipped with additional devices intended for certain road users, such as push buttons for use by pedestrians, cyclists, or moped riders, or acoustic or tactile devices for the blind. Newly installed or replacing pedestrian light signal installations must always be equipped with a tactile device. Temporary installations used during construction do not apply.

Markings shall be painted, applied on the roadway, or embedded; they may also be created by other means (such as paving stones), provided they comply with federal law requirements regarding color, dimensions, and safety of the markings. The markings shall not protrude in an obstructive manner and shall be as non-slip as possible. If necessary, they shall be reflective. Lines marked on the roadway may be equipped with reflectors.

Construction elements that resemble markings, that could be confused with them or impair their effect, or that might give the impression of having a traffic law significance are prohibited.

When roadway markings need to be temporarily displaced (e.g., for construction work, detours), yellow-orange domed discs equipped with yellow-orange reflectors, yellow-orange markings, or elongated yellow-orange delineation elements will be used to indicate that the existing white markings are no longer valid. To better indicate the path to follow, the elongated delineation elements and markings may be supplemented with reflectors.

Directional indications as well as inscriptions provided for by this ordinance may be placed on the roadway. Additionally, the DETEC may provide for special markings, notably to clarify signals or to highlight local peculiarities.

Art. 90 also applies to markings on highways and expressways.

The DETEC issues instructions regarding the markings.

Tactile-visual markings may be used in areas designated for pedestrian traffic (including pedestrian crossings) with the aim of enhancing the safety of blind and visually impaired individuals and improving their orientation.

Permitted are guiding lines, safety lines indicating the boundary of a hazardous area, bifurcation areas at places where direction changes are possible, terminal areas at the end of a guiding line, as well as attention zones, particularly in hazardous locations.

The markings are white; on the roadway, they are yellow.

Safety lines (continuous, white; 6.01) indicate the center of the roadway or delineate traffic lanes. Safety lines also serve to demarcate the roadway or traffic lanes in relation to railway tracks. They should not be longer than necessary, considering visibility and the usual speed of vehicles.

Roadways containing at least three traffic lanes, and, if specific safety requirements demand it, roadways with only two, may be marked with a double safety line (6.02) used to separate the two directions of traffic.

Directional lines (broken, white; 6.03) indicate the center of the roadway or delineate traffic lanes.

Double lines (a directional line adjoining a safety line; 6.04) will particularly be marked where visibility conditions only require a traffic restriction in one direction.

Warning lines (white, broken; 6.05) are used to announce safety lines and double lines. Their marking is mandatory outside urban areas and optional within them.

The various lines have the following meaning: a. Vehicles are prohibited from crossing safety lines and double safety lines or encroaching upon them; b. Vehicles are permitted, with due caution, to cross directional lines and warning lines or encroach upon them; c. Vehicles on the side of the safety line are prohibited from crossing double lines or encroaching upon them.

When a brief (white) broken line is marked parallel to a safety line, the latter may be crossed at that location by vehicles on the side of the broken line. If the brief broken line is marked in yellow, it is exclusively intended for public buses on regular routes as well as cyclists and moped riders.

Traffic lanes shall be delineated by safety lines, directional lines, or double lines (Art. 73). Articles 74a and 74b apply to the delineation of bicycle lanes and bus-exclusive lanes.

Traffic lanes intended for vehicles veering left, veering right, or continuing straight ahead shall be designated by white preselection arrows (6.06) directed in the corresponding direction. The driver may only cross intersections in the direction of the preselection arrows marked on their lane. Yellow arrows are intended exclusively for drivers of public buses in scheduled service; they authorize them to proceed in the indicated direction.

Merging arrows (white, placed diagonally; 6.07) notify the driver that they must leave the traffic lane in the indicated direction.

White directional arrows indicate the direction that drivers must take.

Bicycle lanes and traffic routes on bicycle tracks shall be delineated by a yellow discontinuous or continuous line (6.09). Vehicles must not encroach upon or cross the continuous line. In intersection areas, marking bicycle lanes is only permitted if the priority is removed from vehicles entering the intersection.

The establishment of bicycle lanes on both sides of the roadway is only permitted outside of localities if both halves of the roadway are separated by a marking.

...

When a bicycle track crosses a secondary road and, as an exception and by derogation from Art. 15, para. 3, OCR, users of this track are given priority, the crossing of the road shall be indicated by yellow discontinuous lines; priority must be removed from vehicles traveling on the secondary road, using "Stop" signals (3.01) or "Yield" signals (3.02).

Bicycle tracks, pedestrian paths, and riding trails (Art. 33) situated at the same level shall be separated by a yellow discontinuous or continuous line. Cyclists and moped riders as well as riders are prohibited from encroaching upon or crossing the yellow continuous lines.

On the bicycle tracks and lanes, it is possible to paint the yellow symbol of a bicycle as well as yellow arrows indicating the direction to follow or the order of preselection.

The bicycle symbol is also permitted outside of bicycle tracks and lanes in the following situations: a. on lanes reserved for buses; b. on parking spaces reserved for bicycles and mopeds; c. at the edge of the roadway in front of pedestrian refuges and similar narrow passages where a bicycle lane must be interrupted; d. to indicate bicycle and moped traffic in the opposite direction on one-way streets in the absence of a bicycle lane; e. on right-turn lanes where bicycles and mopeds can continue straight ahead contrary to vehicles in general. In this case, the symbol is complemented by yellow directional arrows; f. in "bicycle boxes" (6.26) near light signal installations; g. on the roadway of 30 zones, provided that the road is part of a defined network of bicycle lanes and priority has been granted to it.

On paths intended for two categories of users (Art. 33, para. 4, and 65, para. 8), it is possible to paint in yellow the symbols of the relevant signals to specify the situation.

Lanes reserved for buses, which are marked with continuous or discontinuous yellow lines and have the yellow inscription "BUS" (6.08), may only be used by public buses in line traffic and, if applicable, by trams or road railways; any exceptions are indicated by a mark or a signal. Other vehicles must not use the bus lanes; however, if necessary (e.g., for turning), they may cross them when they are marked with a discontinuous yellow line.

The stop line (white, solid, and perpendicular to the roadway; 6.10) indicates where vehicles must stop near a "Stop" sign (3.01) and, if applicable, near traffic signals, before a level crossing, and at the end of lanes designated for vehicles that are turning (Art. 74, para. 2), etc. The front part of the vehicle must not cross the stop line.

The stop line, along with the inscription of the word "Stop" on the roadway (6.11), will complement the "Stop" sign unless the road does not have a durable surface. Additionally, a continuous longitudinal line (6.12) should be drawn; this is not necessary on one-way roads.

The yield line (a series of white triangles across the roadway; 6.13) indicates where vehicles must stop, if necessary, near a "Yield" sign (3.02) to give way (Art. 36, para. 2). The front part of the vehicle must not cross the yield line.

The yield line will always complement the "Yield" sign, except on roads without a durable surface, on access roads to highways and semi-highways (Art. 88, para. 1), or on similar layouts. Furthermore, a continuous longitudinal line (6.12) will be drawn where the width of the road allows. On main roads and significant secondary roads, the yield line may be announced by a white triangle painted on the roadway, pointing towards the driver (6.14).

The marking of stop lines and yield lines on main roads that change direction at an intersection is governed by Art. 76, para. 2, letter b.

Stop lines and yield lines concerning only cyclists and moped riders (e.g., on cycle lanes, cycle tracks) may be yellow.

Before traffic signals, yellow stop lines may be marked across the entire width of the traffic lane to indicate cyclist boxes after the white stop lines ("cyclist box", 6.26). In this area, cyclists and moped riders are allowed to position themselves side by side when the light is red. Other drivers must stop before the first stop line (white). Cyclist boxes are only allowed when a cycle lane leads into the affected areas. The presence of the cycle lane is not required if the following conditions are met: a. there is no possibility to turn right, or other vehicles are not allowed to turn right at the intersection, and b. the traffic lane is sufficiently wide.

Edge lines (continuous, white; 6.15) mark the edge of the roadway.

Guidance lines (discontinuous, white; 6.16) provide visual guidance for traffic in the following manner: a. they delineate the roadway as an extension of stop lines and waiting lines (Art. 75) in wide junctions (6.16.1); b. they indicate the path of the main road when it changes direction at an intersection (6.16.2). Junctions of roads will be marked with a stop line or a waiting line. Where it seems appropriate, the corresponding part of the guidance line may be replaced by a stop line or a waiting line (e.g., 6.16.3); c. they constitute a boundary between the roadway and contiguous traffic areas that do not form an intersection with the roadway (Art. 1, para. 8 and Art. 15, para. 3, OSR); d. they delineate areas situated in the middle of the roadway and parallel to it, which do not constitute traffic lanes.

Guidance lines should not be marked at intersections where the right-of-way priority provided by law applies (Art. 36, para. 2, LCR).

Pedestrian crossings are marked by a series of yellow stripes, or white stripes in the case of pavements, parallel to the edge of the roadway (6.17).

Before pedestrian crossings, a line prohibiting stopping (yellow, continuous; 6.18), at least 10 meters in length, will be marked parallel to the right edge of the roadway, at a distance of 50 to 100 cm; it prohibits voluntary stopping on the roadway and on the adjacent sidewalk. On one-way streets, the line prohibiting stopping will be drawn on both the right and left edges of the roadway. It will not be drawn on the surface of intersections, near bicycle lanes, or in parking and stopping bays preceding a pedestrian crossing.

Longitudinal pedestrian stripes (Art. 41, para. 3, OCR) will be outlined on the roadway by continuous yellow lines; the surface of these stripes will be streaked with oblique lines (6.19).

Traffic-prohibited areas (white, hatched, and outlined; 6.20) serve as optical guides for channeling traffic; vehicles must not cross them.

Parking spaces are indicated exclusively by a marking or marked in addition to signage.

Parking spaces are delineated by continuous lines. Instead of continuous lines, partial marking may be used. The markings are white; for spaces located in the "blue zone," they are blue. White or blue parking spaces may also be indicated by a particular surface that stands out clearly from the roadway.

The beginning and end of a "blue zone" may be indicated by a double transverse line in blue and white; the blue line will be on the inside of the zone.

It is possible to reserve parking spaces for the following categories of vehicles and user groups by marking them with a symbol: a. the "Cycle" symbol (5.31) for bicycles and mopeds; b. the "Motorcycle" symbol (5.29) for motorcycles; c. the "Disabled" symbol (5.14) for persons holding a "parking card for people with disabilities"; d. the "Charging Station" symbol (5.42) for electric vehicles being charged; e. the "Carpooling" symbol (5.43) for vehicles transporting, upon arrival, a number of persons at least equal to that indicated on the symbol; f. the "Cargo Bike" symbol (5.31.1) for bicycles and mopeds intended for the transport of children, passengers, or goods, as well as bicycles and mopeds with trailers.

Parking spaces reserved for specific user groups are marked in yellow. Those for bicycles and mopeds may also be marked in yellow.

Where parking spaces are marked, vehicles must park only within the limits of these spaces. Parking spaces should only be used by vehicles of the categories for which they have been dimensioned. Parking spaces reserved for a vehicle category or a user group may only be used by said category or group.

Lines prohibiting parking (yellow, interrupted by x's; 6.22) and parking-prohibited spaces (yellow with two crossed diagonals; 6.23) located at the edge of the carriageway indicate a parking prohibition at the marked location. If the parking-prohibited space bears an inscription such as “Taxi” or a control plate number, or the symbols "Disabled" (5.14), "Charging Station" (5.42), or "Vehicles Equipped with an Automation System" (5.44), stops to allow passengers to board or alight, as well as to load or unload goods, are only permitted if they do not inconvenience the rightful users.

Lines (yellow, continuous; 6.25) marked at the edge of the carriageway prohibit voluntary stopping at the indicated location.

Zigzag lines (yellow; 6.21) indicate spaces reserved for stops by public transport in line traffic. At these spaces, stopping is only permitted to allow passengers to board or alight from the vehicle, provided that public transport vehicles in line traffic are not impeded.

Work zones located on the roadway or in its immediate vicinity shall be indicated by the "Road Works" sign (1.14), which shall be repeated near the work zone itself.

In work zones without obstacles on the roadway, it is permissible to use, to ensure better visual guidance of traffic, red and white striped devices (such as delineation posts, barrels) or cones painted in red and white or in orange.

In work zones with obstacles over 0.5 m in width on the roadway, red and white striped barriers (such as planks, tubular elements, scissor mesh, or other stable elements) shall be used.

The alternating-faced palettes used to control traffic where the roadway narrows display, on the face indicating mandatory stop, the "No Entry" sign (2.02) and, on the other face indicating free passage, a green disc with a white border.

The DETEC issues instructions concerning the placement of signs and markings, barriers, and other devices, their appearance, as well as the lighting of work zones.

The authority or the Federal Roads Office (OFROU) shall provide directives to contractors concerning work site signage and will oversee their implementation.

Near work sites, contractors may only signal traffic regulations (e.g., traffic bans, speed limits, detours) if the authority or OFROU has given its approval and a formal decision has been made (Art. 107, para. 1).

Detours shall be announced in accordance with Art. 55.

Near work sites where work is interrupted for a significant period, signals shall be covered or removed if they are not necessary during this interruption of work.

Delineation devices highlight the route layout clearly and indicate permanent obstacles located within 1 meter of the roadway edge. When a route's layout is easily recognizable, it does not need to be indicated laterally.

Delineation devices are presented as follows: a. the front surfaces of obstacles (e.g., protruding house corners, tunnel portal faces) shall be marked with black and white stripes angled towards the roadway; b. the front surfaces of obstacles (e.g., side walls, curb edges, tunnel walls) shall be marked with vertical black and white stripes or a horizontal band with alternating fields; the tips of guiding arrows shall be white on a black background; c. poles, masts, trees, etc. shall be equipped with horizontal black and white stripes; d. obstacles located above the roadway shall be marked with vertical black and white stripes.

When roadway edges are marked along their entire length by reflectors, the right marker will bear a white rectangular reflector, mounted vertically (6.30), and the left marker will have two round reflectors, colored white and placed one above the other (6.31). On roads with separated traffic lanes and on roads without opposing traffic, any potential left marker will have a vertical white reflector.

Island markers will bear horizontal or vertical white and black or yellow and black stripes.

Traffic separators may be used to divide the roadway on highways or semi-highways.

Yellow folding arrows in illuminated version can be used on moving or stationary vehicles on the roadway.

DETEC issues instructions on the type, execution, and arrangement of delineation devices.

Barriers may be installed where traffic must be temporarily prohibited (e.g., at level crossings, customs posts, near aerodromes). The appearance of these barriers is governed by the provisions related to railway barriers (Art. 93, para. 1).

When road users have to open a barrier themselves, they are required to close it again if it is not automatically operated.

Chains, ropes, or other similar devices may be used in locations where the blockade is short-term and traffic is light; they shall be striped red and white or marked with red and white pennants.

On motorways and semi-motorways, directional signs feature white inscriptions on a green background; conversely, signs or sections of signs indicating destinations accessible via other roads feature white inscriptions on a blue background.

Distances on directional signs as well as on signals placed before an ancillary facility or a hazardous location are indicated in meters, except on the "Distance Panel in Kilometers" (4.65).

When a short section of a main road is constructed as a semi-motorway, this section will generally be signaled in the manner of a main road (art. 37).

A short section constructed as a semi-motorway between a section of motorway and a section of main road will generally be signaled in the manner of a semi-motorway (art. 45, para. 1). The connection of a motorway or a semi-motorway with a short section of another motorway or semi-motorway will be signaled as a junction (art. 86), and not as a branch (art. 87).

The "Motorway" (4.01) and "Semi-Motorway" (4.03) signs shall be placed at the beginning of the access roads to motorways and semi-motorways. The "End of the Motorway" (4.02) and "End of the Semi-Motorway" (4.04) signs shall be placed on the exit roads, shortly before they merge into the regular road network.

The "Motorway" and "Semi-Motorway" signs shall also be placed to indicate the transition from a semi-motorway to a motorway or vice versa; however, they shall not be installed on the connecting sections between two motorways or two semi-motorways.

Junctions are deemed to be places where the access and exit roads join the lanes of a motorway or semi-motorway. They will bear the name of a nearby locality and, if it is a city, the possible indication of the district. Only one locality will be indicated.

Near the junctions, the following must be placed

a. a "Sign Announcing the Next Junction" (4.60), 1000 m before the beginning of the deceleration lane (art. 90, par. 2);

b. an "Advanced Direction Sign for Junctions" (4.61), 500 m before the beginning of the deceleration lane;

c. a "Direction Sign for Junctions" (4.62) at the beginning of the deceleration lane;

d. an "Exit Sign" (4.63) at the top of the angle formed by the junction.

The "Sign Announcing the Next Junction" bears the name of this junction.

The "Advanced Direction Sign for Junctions" includes on the upper part of the panel the name of the junction succeeding the next exit, and on the lower part, the names listed on the "Direction Sign for Junctions." In border localities, a destination center will be indicated in place of the name of the junction succeeding the next exit located on foreign territory. If there is a branch (art. 87, par. 1) after the junction, only the name of the branch should be indicated on the upper part of the panel.

The "Direction Sign for Junctions" bears the name of the junction and, at most, that of two important localities accessible via this junction. Generally, a locality is mentioned only at the closest junction.

When the available space is insufficient, the "Exit Sign" can be replaced by a "Bifurcation Sign" (4.64), placed above the roadway, indicating the destination centers that can be reached directly; on the exit lane, it can be replaced by a "Preselection Sign Above a Traffic Lane on a Motorway or Semi-Motorway" (4.69).

A "Distance Sign in Kilometers" (4.65) must be placed at the junctions 500 m after the end of the acceleration lane (art. 90, par. 2); this sign is not necessary where the junctions repeat at close intervals. It mentions at most five destination centers listed from bottom to top, from the nearest to the furthest. The furthest destination center appears at the top, and the nearest at the bottom; as for destination centers accessible via different motorways or semi-motorways, they will be grouped accordingly.

Signage must be placed near intersections of highways and semi-highways as follows: a. a "Branching Sign" (4.66), 1500 m before the point where the number of lanes increases; b. a "First Advanced Direction Indicator for Intersections" (4.67), 1000 m before the point where the number of lanes increases; c. a "Second Advanced Direction Indicator for Intersections" (4.68), 500 m before the point where the number of lanes increases; d. a "Preselection Sign above a Traffic Lane on Highway or Semi-Highway" (4.69) at the point where the number of lanes increases; if the distance to the apex of the angle formed by the intersection exceeds 200 m, the sign will be repeated at the apex of this angle; if the distance is less than 200 m, it will be replaced at the apex of this angle by a "Bifurcation Sign" (4.64); on sections equipped with a light signal system intended to temporarily close traffic lanes (2.65), the downward arrow will be omitted from signal 4.69; e. a "Distance Sign in Kilometers" (4.65), 500 m after the intersection, on each of the two branches.

The name of the intersection is mentioned on an additional plaque below the "Branching Sign."

The "First Advanced Direction Indicator for Intersections" designates the upcoming major destination centers (Art. 49, para. 4) that can be reached by each of the two branches. If necessary, it can be replaced by the "Preselection Sign above a Traffic Lane on Highway or Semi-Highway."

The "Second Advanced Direction Indicator for Intersections" designates the upcoming major destination centers and, where applicable, other destination centers located on the two branches. This sign can be replaced, if necessary, by the "Preselection Sign above a Traffic Lane on Highway or Semi-Highway."

If the number of lanes does not increase before an intersection, the distance at which the signs are to be placed will be measured from a point located 200 m before the meeting point formed by the extension of the boundary lines delimiting the ramification triangle ("geometric nose").

The "Yield" sign (3.02) shall be placed on the access road, immediately at the point of entry onto the highway or semi-highway. A waiting line (6.13) should not be marked.

On highways and semi-highways, parking areas, gas stations, and other ancillary facilities (e.g., restaurants, information posts) should only be indicated by the corresponding signs if access to the facility or establishment is possible via the highway or semi-highway. Where applicable, the appropriate sign will be placed in the following locations: a. between 2000 and 1000 m before the start of the deceleration lane (Art. 90, para. 2), with the distance indicated; b. 500 m before the start of the deceleration lane, with the distance indicated; c. at the beginning of the deceleration lane; d. at the top of the angle formed by the roadway and the access lane to ancillary facilities.

The "Traffic Lane Arrangement" sign (4.77), equipped with appropriate arrows, will be placed: a. where the number of traffic lanes increases or decreases; b. where traffic is directed, beyond the central berm, onto the roadway serving opposing traffic; c. to confirm, if necessary, the number of traffic lanes.

On highways and semi-highways, the "Radio Traffic Report" sign (4.90) will be placed only: a. where the frequency range changes; b. after major access roads and before relatively long tunnels; c. near the national border.

To announce the next emergency telephone, the "Emergency Telephone Indicator Plaque" (4.70) will be placed at intervals of 50 m on guidance devices or above.

To announce police centers, the "Police Center Indicator Panel" (4.71) will be placed between 700 and 800 m before the access lane or before the corresponding exit, with the distance mentioned. The term "Police" can be repeated on direction panels, below other inscriptions, in black letters on a white background.

Plates indicating the number of kilometers (4.72) and hectometers (4.73) may be placed on highways and semi-highways.

To announce the next gas station, the supplementary plate "Next Gas Station" (5.17) may be placed under the indication panels referred to in para. 1, let. a and b.

The OFROU determines in instructions the indications (e.g., hospital, city center, car loading dock on rail or ferry) that can be affixed, under what conditions, and in what form.

On highways and semi-highways, it is permissible to place panels that provide information on traffic, traffic regulation over a wide area, and road conditions, provided this is necessary for road safety or environmental protection reasons.

The lanes of highways and semi-highways shall be marked without exception (Art. 74, para. 1). They shall be separated from the emergency lane or the edge of the roadway by a border line (Art. 76, para. 1).

At the vicinity of junctions and as extensions of the access and exit lanes of auxiliary facilities, acceleration or deceleration lanes must be marked, separating them notably from the traffic lanes with a double line.

On access lanes, the emergency lane may be marked with oblique stripes.

On access and exit lanes of highways, semi-highways, and auxiliary facilities, the direction to be taken shall be indicated by white arrows drawn on the pavement.

To announce level crossings (Art. 93), the following advance signals are used: a. the "Barriers" signal (1.15) before level crossings equipped with barriers, half-barriers or barriers that open on demand; b. the "Level Crossing without Barriers" signal (1.16) before level crossings equipped with flashing light signals or Saint Andrew's crosses; bbis. the "Tram or Road Railway" signal (1.18) accompanied by a distance plaque before level crossings that, according to railway law, are indicated by the "Tram or Road Railway" signal; c. ...

When level crossings are equipped with flashing light signals, the supplementary plaque "Flashing Lights" (5.12) must be added to the "Barriers" and "Level Crossing without Barriers" signals.

When the signals placed at the level crossing can be recognized early enough, advance signals are not necessary within localities, on rural paths and paths reserved for pedestrians, as well as on access roads belonging to private individuals.

To signal level crossings, barriers, half-barriers, demand-operated barriers, flashing light signals (3.20; 3.21), Saint Andrew's crosses (3.22; 3.24), acoustic signals, "Tramway or Road Railway" signals (1.18), and light signals (Art. 68 to 71) must be used. The appearance and placement of signals at level crossings are governed by railway legislation, except concerning light signals and the "Tramway or Road Railway" signal.

Barriers, half-barriers, or demand-operated barriers which are closed or closing, red flashing lights, red lights, and acoustic signals signify "stop."

...

The road user must independently ensure that no railway vehicle is approaching and that the crossing is clear in the following cases: a. in the presence of the "Tramway or Road Railway" signal (1.18); b. if the Saint Andrew's cross is not accompanied by a flashing light signal or light signals; c. when the yellow light of a light signal installation is flashing.

When a level crossing is located within an intersection where traffic is regulated by light signals (Art. 68 to 71), it may be included in the light signal installation.

...

Considered as road advertisements are all forms of advertising and other announcements made through writing, images, light, sound, etc., which are situated within the drivers' field of perception when they focus their attention on traffic.

Business signs are road advertisements containing the name of the business, one or more indications of the business sector (e.g., "Building Materials," "Horticulture"), and, if applicable, a company emblem, which are placed directly on the business building or in its immediate vicinity.

Road advertisements that could compromise road safety are prohibited, particularly if they: a. make it more difficult to perceive other road users, for example near pedestrian crossings, intersections, or exits; b. obstruct or endanger the rights holders on areas designated for pedestrian traffic; c. can be confused with signals or markings, or d. reduce the effectiveness of signals or markings.

Road advertisements are always prohibited: a. if they are placed within the roadway's clearance profile; b. on the carriageway, except in pedestrian areas; c. in tunnels and underground passages without sidewalks; d. if they contain signals or elements indicating a direction to follow.

Roadside advertisements are prohibited on or immediately adjacent to road signs.

However, the following are permitted: a. roadside advertisements on information panels placed along marked soft-mobility routes indicating the path to follow, provided their surface does not exceed one-fifth of the panel's surface; b. roadside advertisements beneath the "Telephone" sign (4.81) on mountain pass roads, provided their surface does not exceed one-third of the sign's surface; c. announcements focused on road education or prevention.

Road advertisements are prohibited in the vicinity of highways and semi-highways.

However, the following are permitted: a. one business sign in each direction of traffic per business; b. announcements focused on road education or prevention or on traffic management; the surface area of any information pertaining to the sponsorship of the announcement must not exceed one-tenth of that of the sign.

The following are allowed on ancillary facilities and rest areas: a. per service station, one illuminated business sign on the building and one on the median strip between the national road and the ancillary facility; b. per restaurant and per motel, one illuminated business sign on the building, one on its long side, and one on its short side; c. road advertisements, provided they cannot be perceived by drivers on the transit lanes.

The establishment or modification of roadside advertisements requires authorization from the competent authority under cantonal law. The authorization for roadside advertisements on first and second-class national roads is the responsibility of the Federal Roads Office (FEDRO) when it concerns advertisements on the federal estate.

Cantons may establish exceptions to the requirement for authorization when it concerns roadside advertisements that will be placed within localities.

Supplementary regulations on road advertisements are reserved, particularly regulations relating to the protection of sites and landscapes.

Signals and markings not provided for in the present ordinance are not permitted; exceptions are reserved for Articles 54, paragraph 9, and 115.

Signals and markings can only be installed or removed if ordered by the authority or the Federal Roads Office (OFROU); the procedure outlined in Article 107 must be followed.

Signals and markings must not be ordered or placed unnecessarily, nor should they be absent where they are essential. They should be arranged uniformly, especially on the same thoroughfare.

...

Signals apply to the entire roadway unless it is clearly indicated that they are intended only for certain lanes or special traffic areas, either by being placed above the roadway or due to specific arrangements (e.g., Article 59).

Signals should not follow each other at short distances.

Two signals may be installed on the same support; exceptionally and in compelling cases, this number can be increased to three; this principle does not apply to direction indicators. As a general rule, they should be placed from top to bottom: danger signals, regulatory or priority signals, information signals.

Signals may appear on a white rectangular panel: a. when placed above the roadway or above certain lanes; b. within localities when additional information is necessary; c. outside localities on less significant secondary roads (Article 22, paragraph 4) when additional information is necessary; d. on systems with variable signals. The additional information (e.g., an inscription, an arrow, a symbol) is black and appears on the white rectangular panel below the represented signal.

Signals in a luminous version may appear on black rectangular panels.

Yellow and black signals, with the exception of the "Main Road" (3.03) and "End of Main Road" (3.04) signals, are intended solely for military vehicle drivers. The signals have a yellow background; the border, inscription, and symbol are black. The provisions related to the protection of signals (Article 98 LCR) are applicable.

White and orange direction indicators show the direction to follow to reach educational centers, emergency medical posts, as well as relatively large public civil protection shelters that are difficult to identify without a direction indicator. The direction indicators have a white background; the border is orange and the inscription is black; the international emblem of civil protection may appear in an additional field at their base. The provisions related to the protection of signals (Article 98 LCR) are applicable.

The dimensions of the signals are set forth in annex 1.

The large size is reserved for highways; for semi-highways and similarly constructed roads, either the large or intermediate size should be adopted, for main roads and secondary roads the standard size. The small size may be used on rural paths, exits, etc., as well as within localities. On areas dedicated to pedestrians or cyclists, it is possible, in specific cases, to use small-sized warning signals as well as triangular priority signals, reduced by one-third.

Reduced size signals may be installed where there is insufficient space for the standard dimensions (e.g., in tunnels).

Signals must be retroflective or, at night, illuminated; excepted are the direction indicators according to art. 54 a.

The "ASTRA Frutiger" font is used for inscriptions on signals. Exceptions are the numbers as well as the "Enterprise" direction indicators, tourist signage, and direction indicators for hotels.

The signs shall be placed on the right-hand side of the road. They may be repeated on the left side, suspended above the roadway, installed on islands, or, in cases of absolute necessity, placed only on the left. Signs indicating the end of a regulation on secondary roads may be placed only on the left, on the reverse of the opposite sign.

The signs shall be placed in such a manner that they can be seen in time and are not obscured by obstacles. Non-illuminated signs (Art. 102, para. 4) must be placed so that they are visible in the vehicle lights.

The lower edge of the signs shall be between 60 cm and 2 m 50 from the top of the road; this distance shall be at least 1 m 50 on highways and semi-highways, and at least 4 m 50 when the signs are suspended above the roadway. For temporary signage or in cases of urgent necessity, the lower edge of the signs may be lower.

The signs must not protrude into the clear road space profile. The distance between the edge of the road and the nearest side of the sign shall be 30 cm to 2 m within localities and 50 cm to 2 m outside localities, in special cases up to a maximum of 3 m 50; on highways and semi-highways, it shall not be less than the lateral clearance specified by the construction plans.

To warn of particular dangers, the "Other Dangers" sign (1.30) may also be placed on variable message boards of maintenance vehicles or escort vehicles of special vehicles and special transports in motion or stationary on the roadway.

The installation and removal of signals and markings are the responsibility of the authority. The obligation of road users to signal obstacles on the roadway (Art. 4, Sec. 1, LCR; Art. 23 and 54, OCR), the authorization for the police to install necessary signals if they can take measures on their own initiative (Art. 107, Sec. 4; Art. 3, Sec. 6, LCR), and the authorization of convoy vehicle personnel to display the "Other Dangers" signal (1.30; Art. 103, Sec. 5) on variable display panels are reserved.

Cantons may delegate signaling tasks to municipalities but must exercise oversight.

The installation and removal of signals and markings on national roads, including at junctions with connecting routes, auxiliary facilities, and rest areas according to Art. 2, let. c to e, ORN, fall under the OFROU. Signals and markings related to the completion of the national road network, as decided, which are valid for no more than one year, can be installed by the authority following the guidelines issued by the DETEC. Traffic regulations are issued in accordance with Art. 110, Sec. 2.

The Confederation is responsible for signage on other roads and properties it owns, for customs posts (Art. 31, Sec. 1), and for those related to military traffic regulations.

Furthermore, the following individuals have the right to place, in accordance with the authority’s guidelines, the signals listed below: a. owners of private parking spaces: the signal "Parking Authorized" (4.17), which may bear the name of the business; b. owners of private roads, paths, or areas: signals indicating a prohibition or restriction on traffic intended to protect their properties (Art. 113, Sec. 3); c. contractors: signals necessary at construction sites (Art. 80 and 81).

Before installing or removing road markings near level crossings and road signals announcing level crossings and railway vehicles using the road, the authority will consult the railway supervision authority and the railway administration.

The authority exercises supervision in the field of road signage. It also monitors the signs placed by municipalities, organizations, or individuals pursuant to Art. 104, para. 2 and 5, and Art. 115, para. 3.

The authority removes unnecessary signs, replaces those that are damaged, and ensures that markings are renewed in a timely manner. Signs placed without authorization are removed at the expense of the responsible person.

The Federal Roads Office (OFROU) exercises supervision in the field of road signage on national roads and also supervises road advertisements in the vicinity of these roads.

The following may be subject to an application: a. signage and markings that do not comply with the regulations, particularly when signals or markings not provided for are used, when signals or markings have been placed when they were not necessary, or where they are missing in a place where they are needed; b. signals which, according to Art. 107, para. 1, 3, and 4, do not require a decision or publication, as well as markings, insofar as the applicant reports a violation of the legal requirements for their implementation. Any application against signals and markings whose installation has been ordered or approved by the Confederation is excluded (Art. 104, para. 3 and 4; Art. 13, para. 2, SDR in connection with Art. 19, para. 1, lit. g and h).

...

It is the responsibility of the authority or the Federal Roads Office (OFROU) to determine and publish, indicating the legal recourses, the following local traffic regulations (Art. 3, Para. 3 and 4, LCR): a. regulations indicated by mandatory or priority signals or by other signals having mandatory character; b. parking spaces indicated exclusively by a marking.

The signals and markings referred to in Para. 1 can only be installed once the decision is enforceable.

When road safety requires, the authority or OFROU may install signals indicating local traffic regulations as per Para. 1 before the decision is published; however, they can only do so for a maximum of 60 days.

Experimental local traffic regulations shall not be ordered for a period exceeding one year.

No formal decision or publication is necessary for: a. the installation of markings, except for the parking space markings referred to in Para. 1, let. b; b. the installation of the following signals: 1. traffic lights, 2. signals not mentioned in Para. 1, 3. "No entry for vehicles carrying hazardous goods" (2.10.1), 4. "No entry for vehicles whose load may pollute waters" (2.11), 5. "Maximum width" (2.18) on the main roads listed in Annex 2, let. C, of the Ordinance of December 18, 1991, concerning major transit routes, 6. "Maximum height" (2.19), 7. "Maximum speed" (2.30), prescribing the general speed limit on expressways, 8. "Maximum speed 50, General limit" (2.30.1), 9. "Stop near customs post" (2.51), 10. "Police" (2.52), 11. "Main road" (3.03), 12. "Highway" (4.01), 13. "Expressway" (4.03); c. regulations related to construction sites lasting no more than 6 months.

When they must be applied for more than eight days, temporary measures taken by the police (Art. 3, Para. 6, LCR) must be the subject of a decision and publication by the authority or OFROU, according to the ordinary procedure.

If it is necessary to order a local traffic regulation, the measure chosen will be the one that achieves its objective with the least restriction of traffic possible. When the circumstances that determined a local traffic regulation change, this regulation will be reviewed and, if necessary, repealed by the authority.

When the construction or repair of a road requires a local traffic regulation, the construction of islands, etc., the opinion of the authority and the cantonal traffic police will be sought when establishing plans.

If a stop reserved for public vehicles in line traffic is planned, the cantonal traffic police must be consulted before the approval of the plans.

To avoid or mitigate particular road traffic dangers, reduce excessive harm to the environment, or improve traffic flow, the authority or the Federal Roads Office (OFROU) may order exceptions to general speed limitations (Art. 4 a SCR) on certain road sections.

General speed limitations may be lowered when: a. a danger is difficult to perceive or not perceivable in time and cannot be mitigated otherwise; b. certain road users require special protection that cannot be achieved by other means; c. it allows for improved traffic flow on heavily trafficked sections; d. it is possible to reduce excessive environmental harm (noise, pollutants) as defined by environmental protection legislation. In doing so, the principle of proportionality must be respected.

The general speed limit may be increased in well-developed priority roads within localities, if this measure improves traffic flow without harming safety or the environment.

Before establishing an exception to a general speed limitation, an expert report (Art. 32, para. 3, SCR) will be conducted to determine if this measure is necessary (para. 2), appropriate, and respects the principle of proportionality, or if other measures should be preferred. In particular, consideration will be given to whether the measure can be limited to peak hours.

Contrary to paras. 1, 2, and 4, the establishment of 30 km/h zones and meeting zones is governed solely by Art. 3, para. 4, SCR.

The following exceptions to general speed limitations are authorized: a. on highways, speeds lower than 120 km/h, down to 60 km/h, with the gradation set at 10 km/h; within junctions and intersections, further reductions according to the degree of development, with the gradation set at 10 km/h; b. on semi-highways: speeds lower than 100 km/h, down to 60 km/h, with the gradation set at 10 km/h; within junctions and intersections, further reductions according to the degree of development, the gradation being set at 10 km/h; c. on roads outside localities, except for semi-highways and highways: speeds lower than 80 km/h, with the gradation set at 10 km/h; d. on roads within localities: 80/70/60 km/h; for speeds lower than 50 km/h, the gradation is set at 10 km/h; e. within localities, on streets marked with zonal signage, 30 km/h according to Art. 22 a or 20 km/h according to Art. 22 b.

The Department of the Environment, Transport, Energy and Communications (DETEC) regulates the details on how to set exceptions to speed limitations. It establishes the necessary requirements regarding the development, signage, and marking of 30 km/h zones and meeting zones.

Main roads (Art. 57, para. 2, Road Traffic Law) and their numbers are designated in a special ordinance. "Numbered Plaques for Main Roads" (4.57) will only be placed on the most important main roads in accordance with Art. 56.

The authority determines the route of the main road in localities situated on the main road network according to the ordinance mentioned in para. 1; with the consent of the Federal Roads Office (FEDRO), it may, in localities of some importance, designate other main roads or remove them.

When two or more main roads meet, the authority will remove the priority of other roads in favor of one road by placing the "Stop" sign (3.01) or the "Yield" sign (3.02) or will order a roundabout or, in special cases, the right-of-way priority provided by law by placing the "End of Main Road" sign (3.04).

When secondary roads meet, the authority may, if road or traffic conditions require, deviate from the law's right-of-way rule by placing the "Stop" or "Yield" sign, particularly where secondary roads of different construction or importance meet. Art. 39 applies to placing the "Intersection with a Non-Priority Road" sign (3.05) on the priority road.

When after several intersections with the "Intersection with a Non-Priority Road" sign (3.05), there is an intersection where the law's right-of-way priority is applicable, the "Intersection with Right-of-Way Priority" sign (3.06) will be placed before this intersection (Art. 40, para. 2, let. b).

Major transit routes (Art. 2, para. 1, let. a and Art. 3, para. 3, Road Traffic Code) include highways and semi-highways as well as main roads.

The Federal Roads Office (FEDRO) issues local regulations concerning traffic within the limits of Art. 3, para. 4, and Art. 32, para. 3, Road Traffic Code on national roads, including junctions with link routes, auxiliary installations, and rest areas according to Art. 2, let. c to e, National Roads Ordinance (Art. 2, para. 3 bis, Road Traffic Code). Cantons may implement these measures on first and second class national roads provided that they are related to the completion of the national road network as decided and that they do not last more than one year.

The Federal Council may review the appropriateness of the existing local traffic regulations on major transit routes and, if necessary, abolish them.

Cantons will determine the permissible weights and dimensions for special vehicles and exceptional transports on major transit routes (Art. 78 to 85 Road Traffic Ordinance).

...

...

Decisions restricting or prohibiting public traffic on roads and properties owned by the Confederation– except on national roads – (Art. 2, para. 5, LCR) shall be made by the federal department to which the office or entity responsible for the administration of the road or properties is subordinated. Swiss Post and the ETH Board are competent for their properties.

The decisions shall be published in the Federal Gazette and shall indicate the possibility of appeal in accordance with the general provisions of federal procedure.

Restrictions on circulation established under railway police legislation may be announced using the signals outlined in this ordinance. Regarding the placement of signals, the railway company shall coordinate with the cantonal authority.

On public traffic areas belonging to private individuals, the authority may, after having heard the owner, establish traffic regulations and restrictions.

To ensure traffic safety on public roads, the authority may also, at the junction of roads or paths used solely for private purposes, order necessary measures.

The owner who has obtained a prohibition or restriction on traffic on their roads, paths, or plazas to protect their property may install the corresponding signal with the additional plaque "Private," "Private Path," etc., according to the authority's directives.

...

Shall be liable to a fine: a. anyone who has placed road advertisements contrary to the regulations; b. anyone who has directed traffic without the required authorization (Art. 67, para. 3); c. anyone who has manufactured, supplied, or used unauthorized parking disks.

The contractor or person responsible for the signage at a construction site who has violated the provisions of this ordinance concerning construction site signage shall be liable to a fine.

The DETEC may issue instructions concerning the execution, appearance, and installation of signals, markings, demarcation devices, road advertisements, and other similar installations, and can confer binding status to technical standards.

The OFROU may issue instructions regarding the application of this ordinance. In certain cases, it may authorize exceptions to certain provisions, modifications of symbols, or, on a trial basis, new symbols, signals, and markings as well as signs bearing the names of watercourses, indicating paths reserved for pedestrian tourism, etc.

The OFROU may entrust user associations or other organizations with the responsibility of indicating the names of watercourses, paths reserved for pedestrian tourism, campsites, telephone stations, etc., by means of signs. These signs may only be placed in accordance with the directives of the authority.
