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
The construction of transregional "Kraftfahrstraßen" highways ("Autostraßen") rank below the standard of German autobahns. With regard to the general German speed limits, on roads with lanes separated by a median or with a minimum of two marked lanes per direction, an advisory speed limit ("Richtgeschwindigkeit") of 130 km/h (81 mph) applies. At-grade intersections are admissible, regulation at junctions is usually provided by traffic lights or roundabouts. U-turns and any deliberate stopping are prohibited. "Kraftfahrstraßen" are out of bounds to pedestrians, except for special crosswalks.
Expressways in Hungary are called "Autóút" (Auto/car road). They are mostly dual carriageways.
The main difference between Hungarian motorways and expressways is, that they are more cheaply built with narrower width and often undivided. 
Maximum speed limit is reduced to 110 km/h for vehicles under 3.5 tons, and 70 km/h for vehicles over 3.5 tons.
