Vignette is a form of road pricing imposed on vehicles, usually in addition to the compulsory road tax, based on a period of time the vehicle may use the road, instead of road tolls that are based on distance travelled. Vignettes are currently used in several European countries. The term originated in France in the 1950s, although vignettes there were not linked to motorway use and no longer exist; it is now used throughout Central Europe, as well as in Italy (vignetta). Vignettes are used in Austria, Bulgaria, the Czech Republic, Hungary, Moldova, Romania, Slovakia, Slovenia and Switzerland. In most of these countries a small, coloured sticker is affixed to a vehicle windscreen, but in Bulgaria, Czech Republic, Hungary, Romania, Slovakia and since 2021 in Slovenia these have been superseded by electronic vignettes. In Moldova, vignettes are required for the use of any road, while in Bulgaria and Romania they are required for the use of any road outside urban areas. In the other countries, vignettes are required only for the use of motorways and expressways. Prices for an annual vignette for passenger cars range from €30 to €150, depending on country. In all countries except Switzerland, short-period vignettes are sold for visiting or transiting vehicles. In Switzerland, visiting foreign motorists must buy an annual vignette to use the country's motorways. Vignettes can usually be obtained at border crossings, gas stations and other outlets. Improperly used or lost vignettes are usually not refunded. Vignette stickers are usually constructed in such a way that detaching and re-attaching them is impossible without destruction, ensuring that they cannot be used on more than one vehicle. Road traffic is often monitored by roadside cameras, and vignettes are verified by state officials, such as border guards and national police. Hefty cash fines are often charged to travelers using public roads without a valid and properly affixed vignette. Additional tolls are usually levied for passing through certain motorway tunnels and bridges. In Austria a tunnel or bridge subject to a special toll (:de:Sondermautstrecke) is in theory free of the vignette obligation, but in practice this is usually a moot point as access to many of them is via motorway only.
