Germany has an excellent network of major 'B' roads (Bundesstrassen) and 'A' motorways (Autobahnen). Generally, there are no speed limits on much of the Autobahn network, but individually marked speed limits appear on a large percentage of motorway miles. A maximum of 130kph (81mph) is recommended. On normal roads, speed limits are 100kph (62mph) outside built-up areas, and 50kph (31mph) or 30kph (19mph) in built-up areas. Traffic drives on the right. The minimum age for driving is 18 years. Seat belts must be worn at all times and children under 12 years can only travel in the front seat with a child restraint. The legal maximum alcohol to blood ratio for driving is 0.05% (zero for under 21s). Foreign drivers require their national driving licence and proof of insurance - third party insurance is mandatory, but a Green Card is strongly recommended. A country identification sticker must be displayed on the vehicle.
