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.
Speed limits in Norway
Some areas may have lower or higher speed limits. On some roads, the speed limit is 90 km/h, and on the best motorways the limit is 110 km/h. Also, the general speed limits apply only for vehicles below 3.5 metric tons. Lower speed limits apply for larger vehicles. Currently, the maximum speed limit for all vehicles over 3500 kg and all vehicles carrying a trailer is 80 km/h.
