Are 4D Plates Illegal?

Number plates are a legal requirement for any vehicle in the UK, and there are strict regulations surrounding their design and display.

However, in recent years, a new type of number plate has emerged, known as a 4D plate. These number plates have become increasingly popular among car owners who want to give their vehicles that unique look.

But are 4D number plates legal? In this blog post, we'll explore the laws surrounding number plates in the UK and answer the question of whether or not 4D plates are illegal.

What are 4D number plates?

4D plates use a black PMMA acrylic which is placed over the top of the completed number plate, making them more visually striking than traditional number plates.

The number plate is made in the traditional way by printing the registration on the reflective material, laminating the plate with it’s usual clear acrylic and then sticking the black acrylic digits on top.

What Are the Laws Regarding Number Plates?

The laws regarding number plates in the UK are governed by the Driver and Vehicle Licensing Agency (DVLA). There are strict regulations in place to ensure that number plates are easy to read and identify the vehicle they are attached to.

Some of the key regulations around number plates include:

  • The size of the letters and numbers
  • The type of font used
  • The spacing of the letters and the numbers
  • The type of material the plate must be made from
  • Display black characters on a white background (front plate)
  • Display black characters on a yellow background (rear plate)

Additionally, each plate that is fitted after 1 September 2021 must be marked with the new British Standard number – which is ‘BSAU 145e’ as appose to the previous 145d. All number plates must be made of tested and approved reflective material to ensure that they are clearly visible in all lighting conditions too.

Are 4D Number Plates Illegal in the UK?

As long as the 4D plates are manufactured from tested and approved acrylic and reflective material with solid-black, non-reflective characters and meet the other BSAU 145e standards, then 4D number plates are completely legal on UK roads. Ultimately, the plates must be readable both during the day and the night and the characters cannot be removable.

In the unlikely event that a raised letter or number were to fall off, we’ve manufactured all our 4D plates to have the registration also printed underneath the raised characters, ensuring that your plate will always remain road legal and save you from any potential fine.

How to Ensure Your Number Plate is Legal

Although having a 4D plate isn't illegal, it is illegal to have a plate that can't be read. From certain angles, it can be difficult or even impossible to read a 4D number plate if the letters are raised too high. This is why it’s crucial that all 4D plates are made to the BSAU 145e standards.

It’s also vital that you make sure that your 4D plates are either purchased through a reputable supplier or if printing your own plates, that they meet the correct standards. At Uniplate, we ensure that all our 4D plates are manufactured to the British Standard and rigorously checked prior to being dispatched. All our components, which can be purchased separately to make your own plates, also conform to the legislation outlined by the DVLA.
