Art. 74 OSR · Traffic Lanes
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.
