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.
Speed limit
Road speed limits are used in most countries to set the maximum (or minimum in some cases) speed at which road vehicles may legally travel on particular stretches of road. Speed limits may be variable and in some places speed is unlimited (e.g. on some Autobahn sections in Germany). Speed limits are normally indicated on a traffic sign. Speed limits are commonly set by the legislative bodies of nations or provincial governments and enforced by national or regional police or judicial bodies. Even with the minimum speed limit, that violator is punished.
