A lot of people put a lot of store in their car's number plates – wanting to make them look a bit snazzy, cool or individual.

But there are certain rules that have to followed to make sure they are in the correct style and are legally sound.

Fines of up to £1,000 can be issued if they do not follow the regulations.

Recent trends have seen registration numbers displayed with quirky fonts, sizes and incorrect spacing between the letters and numbers.

Road experts from LeaseCar.uk have highlighted seven key things you need to know about registration plates.

Number plates for cars registered in the UK must be made from a reflective material, not have a background pattern, and display black characters on a white background for the front plate, and black characters on a yellow background for the rear plate.

A spokesperson from LeaseCar.uk said: “A number plate is essentially a car’s passport – and you wouldn’t change the format of your own passport, so why mess with your car’s?

“They carry lots of important information to do with tax and licencing, and so not following the rules can result in some very large fines.”

This is LeaseCar.uk’s number plate know-how:

1. Background

Depending on where your number plates are placed, the background colours should be different. Those at the front of a vehicle should have a white background, and rear number plates should have a yellow background.

2. Font

There is a standard font which must be used for number plates. Characters cannot be in italics – as was previously allowed before 2001 – but you can personalise the font only by making the characters 3D.

3. Visibility

Number plates must be displayed at all times on the vehicle – both front and back – and the letters and numbers must be visible at all times, so make sure they’re kept clean! Theft resistant plates are available to make it more difficult for them to be removed.

4. Size

In order to ensure number plates are easy to read, there are lots of specific measurements with regards to the individual characters. They must be 79mm tall and the thickness of the black print 14mm. More details can be found on the Gov.uk website.

5. Flags

You are allowed to display a flag on the left-hand side of the number plate, but only if it relates to the place the car’s from. They must be smaller than 5mm wide. A GB sticker must be displayed if you plan to drive the car in Europe – a flag on the number plate will suffice.

6. Formation

Each car is issued with a regular formation of two letters, which identifies where the car was originally registered, two numbers which show the age of the car, followed by three random letters. It is illegal to put plates on a car which makes it look younger than it is.

7. Personalised plates

Personalised number plates can also be purchased. These adhere to all of the above rules, apart from they can follow different formations. These plates don’t show the age of the car - this is one of the reasons individuals may choose to buy them.
