Europe Austria In Austria works system called ASFINAG (Autobahnen-und-Schnellstraßen-Finanzierungs-Aktiengesellschaft), the Austrian financing provider for and operator of motorways (Autobahnen) and expressways (Schnellstraßen) uses a video tolling system called Videomaut (Video Toll). It covers parts of three motorways which are subject to special tolls (Sondermaut) in addition to the regular tolls paid through a road-tax disc (Vignette) for vehicles with a total weight of no more than 3.5 metric tonnes. Availability Videomaut is available on the following routes: A9 Pyhrn Motorway (Pyhrnautobahn), between Spital/Pyhrn and Ardning and between St. Michael and Übelbach, toll plaza of Bosruck A10 Tauern Motorway (Tauernautobahn), between Flachau and Rennweg, toll plaza of St. Michael i.L.

When approaching a toll plaza, the user must enter the lane marked Videomaut and travel no faster than 15 km/h. The car's number plate is read and identified automatically, and the vehicle is allowed to pass. If the number plate cannot be read, or no valid Videomaut ticket is associated with the number plate, the user is directed into a regular toll lane and must show a copy of the receipt for the Videomaut ticket as proof of purchase to the toll cashier. The toll cashier verifies the validity of the ticket and allows the vehicle to continue or directs the driver to pay the special toll incurred if the ticket is invalid or has expired.
