Art. 73 Ordinance of September 5, 1979, on Road Signage (OSR) - Safety Lines, Directional Lines, Double Lines, and Warning Lines
Art. 73 OSR · Safety Lines, Directional Lines, Double Lines, and Warning Lines
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.
