Speed limits

You must not drive faster than the speed limit for the type of road and your type of vehicle. The speed limit is the absolute maximum - it does not mean it’s safe to drive at this speed in all conditions.

National speed limits

The following speed limits apply to all single and dual carriageways with street lights, unless there are signs showing otherwise:

  • 30 miles per hour (48km/h) in England, Scotland or Northern Ireland
  • 20 miles per hour (32km/h) in Wales

Vans, car-derived vans and dual-purpose vehicles

Most vans:

  • have a lower speed limit than cars
  • must follow the speed limits for goods vehicles of the same weight

Vehicles under 2 tonnes laden (loaded) weight may qualify as a ‘car-derived van’ or ‘dual-purpose vehicle’. These vehicles have the same speed limits as cars.

Motorhomes

Motorhomes or motor caravans are classed as goods vehicles if they:

  • carry goods for exhibition and sale
  • are used as a workshop
  • are used for storage

Locally set speed limits

Local councils can set their own speed limits in certain areas, and these must be clearly signed.

For example:

  • 20mph zone in a built-up area near a school
  • 50mph (rather than 60mph) limit on a stretch of road with sharp bends

Speed limiters

A speed limiter must be fitted on:

  • vehicles with more than 8 passenger seats, for example, buses, minibuses, coaches, stretch limousines
  • goods vehicles with a maximum laden weight of more than 3.5 tonnes

Speed limiters are designed to reduce collisions. They limit the maximum speed of a vehicle by restricting the fuel supply to the engine. Having a speed limiter may mean that your vehicle cannot reach the speed limit.
