RoundaboutSwitzerland
21. Roundabout
A roundabout is a circular road arrangement in which traffic travels around a central island in one designated direction. Vehicles enter and leave through connecting roads, and traffic signs or local rules determine who has priority.
Drivers should reduce speed, choose a suitable lane, observe all road users and signal as required when leaving. The direction of travel, entry priority, lane use and rules for cyclists and pedestrians depend on local traffic signs and regulations.

Who has priority at a roundabout in Switzerland?
At a Swiss roundabout marked with the roundabout and give-way controls, yield to vehicles in the circle approaching from the left. Keep speed low and read any separate arrangements for crossings and lanes.

How should you choose a roundabout lane in Switzerland?
Choose your intended exit before entering and follow the lane arrows and destination signs. Keep to the marked route and make any permitted lane change only when safe; having priority over entering traffic does not give you priority to change lanes.

What should you check when leaving a roundabout in Switzerland?
Signal your intention to leave the roundabout. Check any lane you will enter or cross and look for cyclists and pedestrians at the exit. Give way at an uncontrolled pedestrian crossing to pedestrians already crossing or waiting with a clear intention to cross. Obey any separate crossing signals.
