Speed limits

Different speed limits apply depending on the type of road and the vehicle you're driving. You must not exceed the maximum speed limit set for the road and your vehicle.

Cars towing caravans or trailers30 mph (48 kph)50 mph (81 kph)60 mph (96 kph)60 mph (96 kph)

Remember: The speed limit is the absolute maximum and does not mean it is safe to drive at that speed irrespective of conditions. Driving at speeds too fast for the road and traffic conditions can be dangerous.

Always reduce your speed when:

  • The road layout or condition presents hazards, such as bends.
  • Sharing the road with pedestrians and cyclists, particularly children and motorcyclists.
  • Driving in difficult weather.
  • Driving at night.
