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 limits in Germany
The Nazi-era Road Traffic Act of 28 May 1934 imposed the first nationwide speed limit: maximum in urban areas, but no limit on rural highways or autobahns. In October 1939, the Nazis further throttled speeds in order to conserve fuel: in urban areas, elsewhere. After the war, the four Allied occupation zones established their own speed limits until the divided East German and West German republics were constituted in 1949; initially, the Nazi speed limits were restored in both East and West Germany.
