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
An "autoweg" can consist of two or more lanes. The driving directions can be separated by a roadmarking, or by a central reservation. If a public road ("autosnelweg", "autoweg", "weg") consists of two or more lanes that are clearly separated from each other by a roadside or a space that is not accessible to vehicles, the drivers may not drive on the lane opposite to them.
Some expressways are tailored for local traffic, such as the D28 (Vrbovec Expressway), and some are built as bypasses or beltways, such as the D31 (East Velika Gorica Bypass). Croatia also has a large network of tolled highways for transit traffic with a higher speed limit than expressways. Both highways and expressways are grade-separated throughout their entire length.
Expressways in the Czech Republic, Czech: Rychlostní silnice (abbreviation: R), are defined as dual carriageways with smaller emergency lane. The speed limit is 130 km/h (80 mph). Expressway road signs are white on blue. There are 391.2 km of "rychlostní silnice".
