If you are going to drive on the Swiss highways and some national roads, you will have to purchase a motor charge sticker (Autobahnvignette) for CHF 40. The sticker is valid from December 1 to January 31 after the year printed on the sticker (maximum 14 months). Stickers are available at customs offices, petrol stations, and post offices in Switzerland. Petrol stations abroad, which are close to the Swiss border, sell them as well. Attach the sticker to the windshield of your car. You will find a map of all toll roads on the website of the Federal Customs Administration under “Further Information”.
