Yes. Since 1985, a charge has been levied for the use of Swiss motorways and expressways (1st and 2nd class national roads). It is collected in the form of an motorway tax sticker, which costs CHF 40.
Caravans and trailers are also subject to the charge. Campervans up to a total weight of 3.5 tonnes are subject to the charge. Vehicles with a higher total weight are subject to the heavy vehicle charge.
