Are Carbon Fibre Number Plates Legal in the UK?

June 05 2025, by Reece Dennis, 4 min reading time

Carbon fibre number plates — known for their sporty, high-end look — are a popular mod among car enthusiasts. But with ever-tightening DVLA regulations, many drivers are unsure if carbon-effect plates are still legal to use on public roads.

In this post, we’ll break down what carbon fibre plates are, the current UK laws around them, and how you can achieve the look legally.

🏎️ What Are Carbon Fibre Number Plates?

Carbon fibre plates typically refer to number plates with:

• Characters printed or styled to mimic the weave of real carbon fibre

• A darker or textured appearance

• A custom or layered look often found on 3D gel or 4D acrylic styles

They're designed to give your plate a performance-inspired finish, making them popular on sports cars and modified vehicles.

⚖️ Are Carbon Fibre Plates Legal in the UK?

In most cases, carbon fibre effect plates are not legal for road use in the UK.

Here's why:

The DVLA requires all number plates on road-going vehicles to:

• Use the Charles Wright 2001 font (no stylised or textured characters)

• Be solid black characters on a reflective white or yellow background

• Have no background patterns, including carbon textures

• Meet BS AU 145e regulations (introduced 2021)

Carbon fibre fonts or patterns can reduce contrast, making them harder to read — especially for ANPR cameras and law enforcement.

🚨 Legal Risks of Carbon Fibre Number Plates

If you're caught using non-compliant plates, you could face:

• A £100 fine

• An MOT failure

• Your vehicle being marked as non-roadworthy

• Rejection from ANPR toll roads or ULEZ systems

✅ How to Get the Carbon Look — Legally

Good news: there are still legal alternatives to carbon fibre plates that give you a bold look without risking fines:

1. Gloss Black 4D Plates

   • Solid black, laser-cut acrylic characters

   • Fully DVLA-compliant when produced to correct standards

2. Shadow Plates

   • Dual-layer black plates (matte + gloss) for a subtle "depth" effect

   • Still 100% road legal

3. Show Plates (For Off-Road Use Only)

   • You can use carbon fibre fonts on show plates — perfect for car meets, track days, or photography

🛒 Buying DVLA-Compliant Plates

When purchasing number plates, always check:

• The seller is a DVLA-registered supplier

• The plates include the correct BS code and supplier information

• They’re produced using standard fonts and spacing

At Best Merch, we offer road-legal alternatives like:

• 4D plates in various depths (3mm, 5mm, 10mm)

• Shadow X plates with a layered black finish

• Ghost plates for a clean outline look

📌 Conclusion

While carbon fibre number plates may look great, they’re not legal for use on UK roads unless they meet DVLA specifications — which most don’t. Instead, opt for DVLA-approved styles like solid black 4D lettering or shadow plates to stay stylish and compliant.
