Autobahn
The German autobahns (Autobahn, plural Autobahnen) form the nationally coordinated motorway system in Germany. In German, they are officially called Bundesautobahn (plural Bundesautobahnen, abbreviated 'BAB'), which translates to "federal expressways". German autobahns have no general speed limit, but the advisory speed limit (Richtgeschwindigkeit) is 130 kilometres per hour (81 mph).
Germany's autobahn network has a total length of about 12,845 kilometres (7,982 mi) in 2012, which ranks as the fifth longest highway system in the world behind the National Trunk Highway System (NTHS) of China (95,600 km), the Interstate Highway System of the United States (75,932 km), the expressways of Canada (17,000 km) and the highways in Spain (15,152 km).
