Vehicle loading

Last reviewed against gov.uk on

Vehicle loading covers carrying passengers, luggage, roof loads and trailers — how each affects the car’s handling, braking and the legal speed limits that apply when you are towing.

What’s tested

  • Towing speed limits — 60 mph max on motorway and dual carriageway, 50 on single carriageway
  • How a roof load raises the centre of gravity and reduces stability
  • Securing passengers — child restraints by age and height
  • Snaking trailers — how to recognise and recover
  • Weight distribution within the vehicle and trailer

Common mistakes

  • Loading a roof rack too high without rebalancing the load inside
  • Accelerating into a snaking trailer (ease off the throttle instead)
  • Allowing a child under 12 (and shorter than 135 cm) to travel without an appropriate child restraint
  • Towing at 70 mph on a dual carriageway (the legal limit is 60)
