Swiss Driving Theory · RTA / TRO
In Switzerland, roundabouts follow clear right-of-way rules. Roundabout priority is one of the most frequently tested questions in the theory exam.
Vehicles already inside the roundabout always have priority over vehicles entering from the right. Before entering, the driver must slow down and make sure no priority vehicle is approaching.
Vehicles in the roundabout always have priority over those entering
When entering: The indicator does not need to be used (provided no lane change takes place).
When leaving the roundabout: The right indicator must be activated, but not too early – so that drivers waiting to enter are not misled.
On roundabouts without lane markings, cyclists may deviate from the rule of keeping right. Pay extra attention to two-wheelers in the roundabout and avoid overtaking them where possible.
When entering and especially when exiting, watch out for pedestrians and give them priority at pedestrian crossings.
