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.
Highways in Croatia
The primary high-speed motorways are called autoceste (; singular: "autocesta"), and they are defined as roads with at least three lanes in each direction (including hard shoulder) and a speed limit of not less than . They are marked with a special road sign, similar to the road sign depicting a motorway/autoroute/autobahn in other parts of Europe. In Croatia this sign has green background. The national speed limit on an "autocesta", effective in case no other speed limits are present, is , with a legal tolerance of 10% on speeds over 100 km/h (as of 2009). The Croatian motorway (autocesta) network is long.
