The road system within Switzerland is one of the best in the world and is always being improved. Vehicles on roundabouts have priority and not those entering it.
Seatbelts are compulsory, including in the rear of the car.
Insurance companies may not pay if you are not wearing one. Children under 7 years can only ride in the front of the car when it is impossible for them to ride in the back. You should stop at pedestrian crossings if the pedestrian shows an intention to cross the road. Dipped headlights should always be used in tunnels, fog, and when visibility is reduced. Hazard lights can be used to warn drivers approaching behind you of an accident or traffic jam.
