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.
Autobahn
In 2012, the leading cause of autobahn accidents was "excessive speed (for conditions)": 6,587 so-called "speed related" crashes claimed the lives of 179 people, which represents almost half (46.3%) of 387 autobahn fatalities that year. However, "excessive speed" does not mean that a speed limit has been exceeded, but that police determined at least one party travelled too fast for existing road or weather conditions. On autobahns 22 people died per 1,000 injury crashes; a lower rate than the 29 deaths per 1,000 injury accidents on conventional rural roads, which in turn is five times higher than the risk on urban roads—speeds are higher on rural roads and autobahns than urban roads, increasing the severity potential of a crash.
