Speed limits in Germany
In 1973, in the wake of the 1973 oil crisis, a federal speed limit of 100 km/h (62 mph) on Autobahns was imposed to help conserve fuel for fear of impending future shortages (not for environmental or safety reasons). The measure only lasted from December 1973 to March 1974; while the administration and the Bundestag were in favor of keeping the speed limit, the Bundesrat pushed to repeal the law. As a compromise, a "recommended speed" was introduced on Autobahns and "highways outside of built-up areas with a center divide or without a center divide and a continuous lane for overtaking in both directions". This law is basically still in effect today. Unrestricted non-Autobahn highways, however, have since become virtually non-existent or replaced by "Schnellstraßen", Autobahn-like expressways typically limited to 120 or 130 km/h and normally only covering a few kilometers.
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.
