 Since 1997, the use of all "Autobahnen" and "Schnellstraßen" requires the purchase of a vignette (toll sticker) for passenger cars up to 3.5 tonnes or a "GO-Box" (electronic toll system) for trucks and buses.The toll fee ("Maut") has to be paid to legally access the Austrian Autobahns at any time except the Autobahns listed below.On routes which are more costly to maintain, mostly Alpine routes with tunnels—sections of the Pyhrn Autobahn, the Tauern Autobahn (Tauern Tunnel) and the Karawanken Autobahn (Karawanken Tunnel), as well as the Brenner Autobahn—a toll is collected at time of use via toll plazas and therefore drivers do not need to have a vignette to use these Autobahns.
