Definitions for "autobahn"
an expressway or superhighway in a German-speaking country.
definition: The “Autobahn” is the high-speed motorway most synonymous with speed. Although there are no speed limits for cars in many of the rural sections, limits can apply within densely populated areas and are always in effect for buses, trucks, and cars pulling trailers. Before you press on the gas too much, take notice: an insurance company can deny your accident claim if it's found you have driven at a speed unsafe for the road conditions.
Autobahn (German for "motorway") is an album by Kraftwerk, released in 1974. (The album's 22-minute title track was edited to about 3 minutes for single release, and reached #25 on the US Billboard charts, charting even higher around Europe, getting to #11 in the UK.)
