Requirements for a motorcycle number plate to be legal

The Mandatory Typeface

All number plates made after 31.8.2001 must display the mandatory typeface. Number plates made prior to this date must be substantially the same.

The British Standard

The British Standard sets out the physical characteristics of the number plate. This includes visibility, strength and reflectivity. The British Standard also requires each number plate to be permanently and legibly marked with the
following information:-

  1. The British Standard number (currently BS AU 145d)
  2. The name, trade mark or other means of identification of the manufacturer or component supplier
  3. Name and postcode of the supplying outlet

Offences

It is an offence to alter, rearrange or misrepresent letters or numbers in order to form names or words or in such a way that makes it difficult to read the registration number. Characters must not be moved from one block to the other e.g. AB51 DVL must not be displayed as AB5 1DVL or AB 51DVL. Vehicles with illegally displayed number plates may FAIL the MoT test. The police can also issue fixed penalty fines for illegally displayed number plates. Offenders are liable to a MAXIMUM FINE of £1,000 and in some cases the mark may be withdrawn.
For vehicles with new or replacement number plates fitted after 31.8.2001, “3-line” number plates are no longer permitted.
