Autobahns of Austria
Unlike German autobahns, on Austrian autobahns a general speed limit of 130 km/h (81 mph) is set, although as of August 25, 2018, the FPÖ government has been going on a trial for a possible speed limit increase to 140 km/h (87 mph) on the Autobahn 1 freeway. They may only be used by powered vehicles that are designed to achieve at least . While on the motorway voluntary stops, U-turns and backward driving are prohibited.
Limited-access road
In Austria the speed limit on a "Schnellstraße" is 100 – 130 km/h. Schnellstraßen are very similar to Austrian "Autobahnen" (freeways/motorways); the chief difference is that they are more cheaply built with smaller curve radius, often undivided and have fewer bridges and tunnels.
