One of the most common questions we get asked is whether you can adjust the spacing on your number plates to make your registration look different. The short answer is no – altering the spacing on number plates is illegal in the UK and can result in fines, MOT failures and even having your vehicle taken off the road.
What Does the Law Say?
UK number plates must comply with BS AU 145e regulations, which specify exact character dimensions and spacing:
- Characters must be 79mm tall (64mm for motorcycles).
- Character width must be 50mm (except for 1 and I).
- Stroke width must be 14mm.
- Space between characters: 11mm.
- Space between groups: 33mm.
- Minimum 11mm margin around the plate edge.
Why Do People Want to Alter Spacing?
Some drivers adjust the spacing on their plates to make their registration appear to spell a name or word. For example, spacing “M45 TER” differently to make it look like “MASTER”. Whilst this might seem harmless, it is a criminal offence under the Vehicles (Crime) Act 2001 and the Road Vehicles (Display of Registration Marks) Regulations 2001.
What Happens If You Get Caught?
- Fixed penalty notice – Up to £1,000 fine.
- MOT failure – Your vehicle will fail its MOT if plates are incorrectly spaced.
- Plate confiscation – Police can remove illegal plates on the spot.
- Registration revoked – In serious cases, the DVLA can withdraw your registration entirely.
