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 the United States by jurisdiction
The Revised Code of Washington permits speed limits of 75 mph in sections deemed appropriate by an engineering study. As of February 2016, the typical speed limit on a Washington freeway is 70 mph rural, 60 mph urban (the speed limits on these types of freeways only vary in the Tri Cities), with a truck speed limit no higher than 60 mph. The posted truck speed limit does not apply to any auto stage towing a trailer or trucks less than 10,000 pounds gross weight. Limits were raised to current speeds following the elimination of the federal 55 mph speed limit, to more closely reflect the common speeds of traffic at that time. There are a wide range of speed limits statewide, due to legislated flexibility for WSDOT in balancing the desire for transportation speed against safety considerations for any particular stretch of highway.
