Speed Limits Table

There are speed limits for differing classes of vehicles, and speed limits for differing classes of road. Where these differ the lower limit applies. For example, a 7t lorry is subject to a speed limit of 50mph on derestricted single-carriageway roads but on urban roads with a 40mph, 30mph or even (in some residential areas) 20mph limit it is always the lower road limit which applies. Similarly certain stretches of motorway are subject to maximum speeds of below 70mph. They are appropriately signed in all cases.

Indicated speed limits for principal classes of vehicle.

Notes for table

  • A car derived van is a goods vehicle constructed as a derivation of a car and having a maximum laden weight not exceeding 2t.
  • All the limits stated are the maximum permissible for different types of vehicle. Account must be taken of the actual speed limits prescribed over particular roads.
  • By virtue of DPP v Holtham (1990) certain recovery vehicles which carry a substantial part of the weight of the broken-down vehicles are deemed to be goods vehicles and must obey at the appropriate limit for goods. vehicles exceeding 7.5t drawing a trailer. These vehicles are still considered to be locomotives for the purpose of calculating the number of trailers that may be drawn.
