Bundesstraße
One distinguishing characteristic between German "Bundesstraßen" and "Autobahnen" is that there usually is a general 100 km/h (62 mph) speed limit on federal highways out of built-up areas, as opposed to the merely advisory speed limit ("Richtgeschwindigkeit") of 130 km/h (83 mph) in unmarked sections of the autobahns. However, a number of "Bundesstraßen" have been extended as expressways (dual carriageways) (colloquially called "Yellow Autobahns"). Many of these have speed limits of usually 100–120 km/h, others have only an advisory speed limit like autobahns. Most sections of the federal highways are only single carriageway with one lane for each direction and no hard shoulder pull-out area.
Autobahn
Driving in Germany is regulated by the Straßenverkehrs-Ordnung ("road traffic regulations", abbreviated StVO). Enforcement on the federal Autobahnen is handled by each state's Highway Patrol ("Autobahnpolizei"), often using unmarked police cars and motorcycles and usually equipped with video cameras, thus allowing easier enforcement of laws such as tailgating. Notable laws include the following.
"", "", and "Burnout Dominator" use autobahn as one of their tracks. "Euro Truck Simulator", "German Truck Simulator", and "Euro Truck Simulator 2" features the Autobahn in its open world map. "Burnout 3: Takedown" named them as Alpine while "Burnout Dominator" divided them into two (Autobahn and Autobahn Loop).
"" also had a track that had the player drive across different sections of the autobahn. The entire game world of "" is set on the autobahn.
On "Gran Turismo 5" and "Gran Turismo 6", a trophy is awarded to those who have driven the same distance as the autobahn total length. In December 2010 video game developer Synetic GmbH and Conspiracy Entertainment released the title "Alarm für Cobra 11 – Die Autobahnpolizei" featuring real world racing and mission-based gameplay. It is taken from the popular German television series about a two-man team of "Autobahnpolizei" first set in Berlin then later in North Rhine-Westphalia.
