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 France
Minimum or recommended speeds are very rarely marked in France, though vehicles incapable of sustaining 60 km/h are not allowed on highways/motorways and you must be driving at 80 km/h or higher to use the left-most lane of a highway/motorway. Posted speed limits, to conform to the French Highway Code, must be in odd multiples of ten (e.g., 10, 30, 50, etc.), though you can still see 40, 60 and 80 sometimes.
