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 the Netherlands
Speed limit enforcement is extensive on Dutch roads, including traffic enforcement cameras in urban areas and radar guns on national roads and motorways. Furthermore, fixed average speed checks ("trajectcontrole"), which were first introduced in the Netherlands, are now in operation on many motorways in the densely populated Randstad region. In case of speeding, there is a legal speed correction of 3 km/h (3% if over 100 km/h) plus a fixed 3 km/h tolerance margin for posted speed limits up to 120 km/h (i.e. you will be fined from 4 km/h over). For example, when caught at 108 km/h on a national road, one will be fined for exceeding the speed limit by 3.24 km/h. When driving at 107 km/h, no speeding ticket will be issued.
