Motorcycles and tricycles

Motorcycles registered from 1 September 2001 must only display a number plate at the rear of the vehicle.

Motorcycles registered before 1 September 2001 can display a number plate at the front, but do not have to. The number plate must be a 'two-line' number plate.

Motorcycle number plates should have a:

• character height - 64 millimetres
  
• character width - 44 millimetres (except the figure 1 or letter I)
  
• character stroke - 10 millimetres
  
• space between characters - 10 millimetres
  
• space between groups - 30 millimetres
  
• top, bottom and side margins - 11 millimetres (minimum)
  
• vertical space between groups - 13 millimetres
  

Tricycles made from motorcycles must meet the number plate requirements for motorcycles.

Tricycles made from four-wheeled vehicles, such as saloon cars and quad bikes must meet the same number plate requirements as all other vehicles.
