what is the national speed limit in the 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]
Advisory speed limit The signage for advisory speed limits is not defined by the Vienna Convention on Road Signs and Signals, and is therefore not standardised internationally. The United States uses a small yellow sign under the main warning sign, as well as a standalone variation on the standard speed limit sign, with a yellow background instead of a white one, the words "speed limit" omitted and an additional panel stating the type of hazard ahead. Though they list speeds, the U.S. advisory speed signs are classified as warning signs, not regulatory signs, as primary speed signs are.[6] Australia uses a similar design as the U.S. in spite of regulatory speed limit signs being quite different. Germany used a square sign with a blue background and white lettering, similar to the minimum speed limit sign,[5] and New Zealand uses a yellow background with black lettering (similar to the Australian design without the "km/h" lettering). The United Kingdom currently uses an oblong white rectangle with black lettering stating "Max Speed".
