The Road Traffic Act defines the traffic regulations, regulates traffic on public roads and defines responsibilities in case of accident.
All road users must obey the traffic regulations (Road Traffic Act, Articles 26 to 57).
Motor vehicles (cars, vans, trucks and buses) and motorcycles must have their headlights on when being driven during daylight hours. Exempted from this requirement are mopeds, e-bikes and bicycles, and vehicles that were registered before 1970. Anyone who fails to comply with the requirement to drive with headlights on will be fined CHF 40.
