what is speed limit on motorway in 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]
M1 motorway The first section of motorway was the Preston Bypass in Lancashire, which opened in 1958 (now part of the M6 motorway).[3] The M1 was Britain's first full-length motorway and opened in 1959.[5] The early M1 had no speed limits, no central reservation or crash barriers, and no lighting.[6]
