Can Personalised Number Plates Affect Your MOT?

Personalised number plates are a popular way to add a unique touch to your car. However, many drivers in the UK are unaware that customised plates must still meet strict legal standards. Failure to comply with these regulations could result in your vehicle failing its MOT. Here’s what you need to know.

What Are the Legal Requirements for Number Plates?

All number plates in the UK, whether standard or personalised, must follow specific guidelines set out by the Driver and Vehicle Licensing Agency (DVLA). These include:

• Correct font and size: Only the standard "Charles Wright" font is permitted.
• Spacing: Characters must be spaced according to legal standards.
• Material and reflectivity: Plates must be made from reflective material and free from background patterns.
• British Standard mark: Plates must display the relevant mark to show they meet regulations.

If your personalised number plate fails to meet these standards, your car may not pass its MOT.

How Can Personalised Plates Cause MOT Failure?

During an MOT test, number plates are checked for clarity and compliance. Plates that are difficult to read, incorrectly spaced, or contain non-standard fonts or symbols can be flagged as a defect. Common issues include:

• Using illegal fonts or altered characters.
• Incorrect spacing to form a name or word.
• Obscured plates due to dirt, damage, or tinted covers.

Any of these issues may lead to a "major defect" on your MOT report, meaning your vehicle will fail the test.

Can Decorative Features Affect Your Plates?

Some drivers add decorative features such as logos, borders, or tinted film to their plates. While certain national identifiers (such as a UK or GB sticker) are permitted, extra decorations or darkened covers are not. These can obscure your plate and result in a failed MOT.

How to Ensure Your Personalised Plate Passes the MOT

To avoid MOT issues, always ensure your number plates are:

• Legally compliant: Follow DVLA guidelines for font, size, and spacing.
• Well-maintained: Keep them clean and free of damage.
• Free from illegal alterations: Avoid novelty plates or covers that obscure the characters.

If in doubt, check your plate with a registered supplier or review the DVLA’s rules before your MOT.

Conclusion

Personalised number plates can make your car stand out, but they come with responsibilities. If your plates do not meet UK regulations, they could cause your vehicle to fail its MOT, potentially leading to fines and the need for retesting. Ensuring your plates are legal and properly displayed will save you time, money, and hassle during your MOT inspection.
