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 Spain
Bicycles and mopeds are not allowed to access a motorway – exceptionally bicycles may ride on the shoulders of autovías, but mopeds are banned.On standard roads (but not motorways or autovías), cars and motorbikes are allowed to overtake at 20 km/h over the standard limit, if the vehicle being overtaken is travelling below the speed limit, and there is no posted speed limit lower than the standard. This permission decreases the time needed to overtake, and increases safety in the process.
