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.
Highways in the Czech Republic
As of 2016, the former expressways that don't meet motorway standards, have been classified as roads for motorcars ("silnice pro motorová vozidla"). Those common roads are not subject to a fee (in form of a vignette) for vehicles with total weight up to 3.5 t and their high speed limit is of 110 km/h, partially up to 130 km/h. The signs on roads for motorcars have, like on other common roads, a white text on a blue background (unlike on motorways, where the background is green). Exits, like on motorways, are usually numbered.
