national speed limit on a single carriageway uk
Road speed limits in the United Kingdom The national speed limit is 70 mph (112 km/h) on motorways, 70 mph (112 km/h) on dual carriageways, 60 mph (96 km/h) on single carriageways and generally 30 mph (48 km/h) in areas with street lighting (restricted roads). These limits may be changed by road signs and apply to cars, motorcycles, car-derived vans up to 2 tonnes maximum laden weight (MLW), and to motorhomes or motor caravans not more than 3.05 tonnes maximum unladen weight. Other classes of vehicles are subject to lower limits on some roads.[1]
Autobahn Germany's autobahns are famous for being among the few public roads in the world without blanket speed limits for cars and motorcycles. As such, they are important German cultural identifiers, "... often mentioned in hushed, reverential tones by motoring enthusiasts and looked at with a mix of awe and terror by outsiders."[1] Some speed limits are implemented on different autobahns.[22]
