If you are renting a car within Switzerland, the mandatory motorway vignette (a flat-fee toll sticker) is almost always already included in the rental price and affixed to the windshield by the rental company. However, if you are renting a car in a neighboring country (like France, Germany, or Italy) and plan to drive into Switzerland, you are responsible for ensuring the car has a valid vignette. In 2026, you can choose between the traditional physical sticker or the more convenient e-vignette, which is linked to the vehicle's license plate. The vignette costs CHF 40 and is required for all motorways and expressways marked with green signs. Driving without one can result in a CHF 200 fine plus the cost of the sticker. Always verify with your rental agent if the car is "Swiss-ready" before crossing the border.
