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 doesn’t mean it’s safe to drive at this speed in all conditions.

A speed limit of 30 miles per hour (mph) or 48 kilometres per hour (km/h) usually applies, unless you see signs showing otherwise.

Vans, car-derived vans and dual-purpose vehicles

Most vans under 7.5 tonnes laden (loaded) weight, including Ford Transit vans:

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

A vehicle qualifying as a ‘car-derived van’ or ‘dual-purpose vehicle’ has the same speed limits as a car.

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:

  • 20 mph zone in a built-up area near a school
  • 50 mph (rather than 60 mph) 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, eg buses, minibuses, coaches, stretch limousines
  • goods vehicles with a maximum laden weight of more than 3.5 tonnes

Speed limiters are designed to reduce accidents. 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 can’t reach the speed limit.
