Displaying number plates

2. Rules for number plates

Your number plates should:

  • be made from a reflective material
  • display black characters on a white background (front plate)
  • display black characters on a yellow background (rear plate)
  • not have a background pattern

Characters on a number plate can be 3D.

If you ride a motorbike or motor tricycle

Motorcycles and motor tricycles registered on or after 1 September 2001 must only display a number plate at the rear of the vehicle.

If you ride a motorbike or motor tricycle registered before 1 September 2001 you can also display a number plate at the front, but you don’t have to.

Motorcycle and motor tricycle number plate numbers should be on 2 lines.

Towing a trailer

Your trailer must display the same number plate as the car you’re towing it with. If you’re towing more than one trailer, the number plate must be fixed to the trailer at the back.

Letter spacing, size and style

The characters on a number plate need to be a certain height and size.
