If you’ve fitted 4D plates to your vehicle, you might be wondering whether they could attract police attention or even result in an official notice requiring you to fix them.
The short answer is yes, police can issue a Vehicle Defect Rectification Scheme (VDRS) notice for 4D number plates, but only if those plates don’t meet UK legal standards. If your road legal 4D acrylic plates comply with British Standard BS AU 145e and DVLA regulations, you have nothing to worry about.
In this guide, we’ll explain what a VDRS notice is, when police can issue one for 4D plates, and what steps to take if you receive a notice. We’ll also show you how to check whether your plates are compliant and where to get replacements if needed.
The Vehicle Defect Rectification Scheme (VDRS) allows police to issue notices for minor vehicle defects that can be easily fixed. Instead of an immediate fine or penalty points, you’re given a set period (usually 14 days) to rectify the problem and provide proof of repair.
VDRS notices are commonly issued for issues like faulty lights, worn tyres or defective number plates. The system is designed to encourage compliance rather than punish minor offences, giving drivers a chance to fix the problem without financial penalty.
However, if you fail to rectify the defect within the given timeframe or ignore the notice altogether, you could face prosecution, a fine of up to £1,000, and in some cases, penalty points on your licence.
The notice must be responded to properly. You’ll typically need to have the defect fixed, then take your vehicle to a designated police station or approved garage for inspection, or submit photographic evidence that the issue has been resolved.

Yes, 4D plates are legal, provided they meet all requirements set out in UK law. The key regulations governing number plates are the Road Vehicles (Display of Registration Marks) Regulations 2001 and British Standard BS AU 145e.
Legal 4D plates must meet these criteria:
Understanding DVLA regulations of 3D 4D number plates helps ensure you stay compliant.
The raised acrylic characters on 4D plates are not prohibited by law. What matters is that the finished plate is clear, reflective and meets the exact specifications laid out by the DVLA and British Standard. For more technical detail, see the science behind 4D plates and their interaction with speed cameras.
Many drivers worry about whether 4D plates attract more police attention. The reality is that compliant 4D plates should not cause issues. Problems arise only when plates have incorrect fonts, illegal spacing, tinted covers or other modifications.
Police can issue a VDRS notice if your 4D plates fail to meet legal standards in any way. Common reasons include:
Incorrect character spacing: If letters or numbers are too close together or spread too far apart, the plate is non compliant. Some suppliers alter spacing to create a personalised look, but this is illegal on road legal plates.
Wrong font or sizing: All UK plates must use the Charles Wright font at specific dimensions. If your 4D characters use a stylised or decorative font, or are undersized or oversized, they breach regulations.
Missing or incorrect markings: Legal plates must display the British Standard mark, the name and postmark of the registered supplier, and in some cases, the DVLA security hologram. If these are absent or incorrect, the plate is not legal.
Tinted covers or non reflective materials: Some drivers add covers or use materials that reduce reflectivity. This makes the plate harder to read, especially at night or in poor weather, and is grounds for a VDRS notice.
Obscured or damaged plates: Even if your 4D plate was legal when fitted, damage, dirt or fading can make it illegible. Police can issue a notice if they cannot clearly read your registration. For guidance on this, see our article on how 4D plates perform in low light conditions.
If you’ve fitted plates that don’t meet these standards, or if your plates have deteriorated over time, police have the power to issue a VDRS notice requiring you to replace them.
For company vehicle drivers, it’s worth checking are 4D plates allowed on company cars to understand employer policies alongside legal requirements.
Before you worry about enforcement, it’s worth checking whether your plates meet legal standards. Here’s how:
Visual inspection checklist:
If you answer no to any of these, your plate may not be compliant. Our guide on how to check if your 4D plates are insurance compliant provides additional detail on what insurers and the DVLA expect.
You can also compare your plates against official DVLA guidance. Visit gov.uk/displaying-number-plates for the most current rules and visual examples.
If you’re uncertain, take a photograph of your plate in daylight and low light conditions. If the characters are difficult to read or the reflectivity is poor, replacement may be necessary.
Drivers in regions with heavy winter conditions, such as those in Edinburgh, Belfast or Northern Ireland, should pay extra attention to whether plates have been damaged by road salt. See are 4D plates affected by road salt in winter for more.
If police issue you with a VDRS notice for your 4D plates, don’t panic. Follow these steps to resolve the issue quickly and avoid further penalties.
The notice will explain what defect has been identified, the timeframe for rectification (usually 14 days), and where you need to present your vehicle or evidence once the work is complete.
Make a note of the date, the officer’s details, and the specific issue mentioned. This information will be important if you need to appeal or seek clarification.
The quickest solution is to fit new, compliant plates. You can order 4D plates from a registered supplier who guarantees compliance with British Standard BS AU 145e.
Alternatively, if you prefer a more traditional option, 3D gel plates or 2D printed plates are both legal and widely available.
Make sure the replacement plates clearly display the British Standard mark, the supplier’s details, and meet all spacing and font requirements.
For specialist vehicles, consider bike plates, square plates or hex Lambo plates if appropriate for your vehicle type.
Once your new plates are fitted, you’ll need to show proof that the defect has been corrected. Depending on the notice, this may involve taking your vehicle to a police station or approved garage for inspection, or submitting photographs showing the new compliant plates.
Keep receipts, invoices and any correspondence as evidence. If challenged later, you’ll be able to demonstrate you acted promptly.
Ignoring a VDRS notice can result in prosecution and a court summons. Even if you disagree with the notice, respond within the given timeframe and seek advice if necessary.
If you believe the notice was issued in error, you can write to the issuing police force explaining your position. Include photographs of your plates, proof of compliance (such as the British Standard mark and supplier details), and any supporting documentation.
Here’s a simple template:
Dear [Police Force],
I am writing in response to VDRS notice [reference number] issued on [date]. I believe my number plates comply with the Road Vehicles (Display of Registration Marks) Regulations 2001 and British Standard BS AU 145e.
Enclosed are photographs of the plates and proof of purchase from [registered supplier]. I respectfully request that the notice be reviewed.
I am happy to present the vehicle for inspection if required.
Yours sincerely, [Your name]

We also stock show plates for off road use and a full range of number plate accessories including fixings, covers and care products.
Police can issue a VDRS notice for 4D plates if they don’t comply with UK legal standards. But if your plates meet British Standard BS AU 145e and DVLA regulations, you have nothing to worry about.
If you do receive a notice, act quickly. Replace non compliant plates with legal alternatives, provide evidence of rectification, and respond within the deadline. Most cases are straightforward and can be resolved without fines or penalty points.
