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
The construction of transregional "Kraftfahrstraßen" highways ("Autostraßen") rank below the standard of German autobahns. With regard to the general German speed limits, on roads with lanes separated by a median or with a minimum of two marked lanes per direction, an advisory speed limit ("Richtgeschwindigkeit") of 130 km/h (81 mph) applies. At-grade intersections are admissible, regulation at junctions is usually provided by traffic lights or roundabouts. U-turns and any deliberate stopping are prohibited. "Kraftfahrstraßen" are out of bounds to pedestrians, except for special crosswalks.
Expressways in Hungary are called "Autóút" (Auto/car road). They are mostly dual carriageways.
The main difference between Hungarian motorways and expressways is, that they are more cheaply built with narrower width and often undivided. 
Maximum speed limit is reduced to 110 km/h for vehicles under 3.5 tons, and 70 km/h for vehicles over 3.5 tons.
