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.
Limited-access road
In Austria the speed limit on a "Schnellstraße" is 100 – 130 km/h. Schnellstraßen are very similar to Austrian "Autobahnen" (freeways/motorways); the chief difference is that they are more cheaply built with smaller curve radius, often undivided and have fewer bridges and tunnels.
