What is a 4D 3mm plate?

This is a type of four-dimensional number plate, which has 3mm black, acrylic characters.

These acrylic characters are professionally laser cut from acrylic sheets, for ultimate precision and a premium appearance. It also allows the characters to be thicker and more rectangular, for an eye-catching look.

An industrial-strength, long lasting resin is applied on top of these characters. This is a high-strength adhesive which achieves a distinct, deep-raised appearance on the letters and numbers on the registration plate.

A 4D 3mm plate will add a touch of luxury to any car, van, motorbike or lorry.

4D number plates are more pronounced, in contrast to 3D plates, which are softer.

Are 4D 3mm plates legal?

We would always recommend shopping with a trusted supplier of personalised number plates.

A business may claim that their number plates are legal for road use, but in actual fact, the plate may not contain the correct spacing, font, colours, or reflective background that that are required by UK law.

It is your responsibility to check that your custom number plate is legal for usage on UK roads.

So, are 4D 3mm plates legal?

Well, 4D 3mm number plates are legal for road use, as long as they meet the conditions set out by the DVLA.

All 4D number plates have to be made to British Standard, which is the standard that all new number plates on UK roads should be manufactured to by law. This standard has been effective since 2001.

Read on below to see a summary of the DVLA’s rules for number plates in the UK.

What are the rules for number plates in the UK?

UK law stipulates that number plates must display writing in an untitled font called Charles Wright New or Mandatory. The letters and numbers must comply with specific spacing and alignment.

The current vehicle registration number format was introduced in 2001. It consists of:

  • 2 letters (these refer to the region in the country where your vehicle was first registered)
  • 2 numbers (these tell you when it was issued)
  • 3 letters are chosen at random

By law, the DVLA requires the number plates on your vehicles to meet the following conditions:

  • be made from a reflective material
  • display black characters on a white background (for the front plate)
  • display black characters on a yellow background (for the rear plate)
  • not have a background pattern
  • be marked to show who supplied the number plate
  • be marked with a British Standard number – this is ‘BS AU 145e’ for plates fitted after 1 September 2021

The characters on your number plate must not be removable or reflective. If your number plates were fitted after 1 September 2021, they must also be a single shade of black.

On your number plate, the law allows you to have 3D (raised characters), certain flags, symbols and identifiers. If you have a zero-emission vehicle, your number plate is allowed to display a green flash.

Moreover, it is illegal to disfigure number plates in a way which makes them hard to read. For example, if your private plate has the number ‘1’, you cannot place a screw or bolt on top of it to make it look like the letter ‘I’.

Will police pull me over if I am driving with a 4D 3mm plate on my car?

Police will only pull you over if your 4D plate is illegal and doesn’t meet the requirements of the DVLA.

On your number plate, the acrylic characters must be displayed in black, on a white background for the front of the vehicle, and on a yellow background for the rear of the vehicle.

If your number plate is incorrectly displayed or dirty, you could be fined up to £1,000 and your vehicle may fail its MOT test.

Here at Bespoke Plates, our 4D 3mm plates are 100% road legal, so you won’t have to worry about running into legal trouble if you purchase a legal plate from us.
