Art. 68 Ordinance of September 5, 1979, on Road Traffic Signs (OSR) - Types and Meaning of Light Signals
Art. 68 OSR · Types and Meaning of Light Signals
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.
