Switzerland has a two-class highway system: motorways with separated roads for oncoming traffic and a standard maximal speed limit of 120 kilometres per hour (75 mph), and expressways often with oncoming traffic and a standard maximal speed limit of 100 kilometres per hour (62 mph).
Autobahnen in German, autoroutes in French, autostrade in Italian, autostradas in Romansch are the local names of the national motorways of Switzerland. Two of the most important freeways are the A1, running from St. Margrethen in northeastern Switzerland's canton of St. Gallen through to Geneva in southwestern Switzerland, and the A2, running from Basel in northwestern Switzerland to Chiasso in southern Switzerland's canton of Ticino, on the border with Italy.
Autostrassen in German, semi-autoroutes in French, semiautostrade in Italian, autovias in Romansch are the local names of the national expressways.
Motorways and expressways are restricted to motorized vehicles that can attain a speed of at least 80 km/h (50 mph) (VRV/ORC/ONC Art. 35 1).[1]
For the usage of any motorways or expressways the purchase of a motorway sticker ("vignette") to be put on the car's windshield is mandatory.[2]
