One question that often comes up on car forums in the UK is, “Are stick on registration plates legal in the UK?
Here we are going to have a look at some of the facts and give you our interpretation of the law, but please remember it’s just our view and should not be considered as legal advice in any form. Above all remember, You could be fined up to £1,000 and your car will fail its MOT test if you drive with incorrectly displayed number plates.
By stick on registration plates we mean the type often seen on the old E-type jag, which would have been road legal at the time as the law was very much different to now. So could you fit one of these old style stick on plates to your modern car? Probably not as any number plate made after 1st September 2001 must meet the present requirements unless it was first registered before 1st 1973. So let us look deeper into this to find out why. We need to first understand what materials are used to construct a reg plate and how it’s assembled.
What Are Registration Plates Made Off?
A conventional UK registration plate used on a modern car is a composite made up of a plastic front and a reflective backing with the charters stuck to it or printed on it. The plastic front is effectively a shield to protect the lettering from becoming damaged by stones and everyday driving.
What Is a Stick on Plate Made of?
This depends on the supplier, but generally, they are supplied as the same reflective material as a standard plate but are designed to be stuck on the vehicle rather than screw mounted or placed in a secure holder like many new cars. However, they don’t have the front rigid plastic protective layer and are wafer thin.
Legal Reg Plates
The UK government has produced a leaflet entitled INF104: vehicle registration numbers and number plates in that 12-page leaflet it sets out the standard for the for UK registration plates, but crucially it states on page 8 the following.
The British Standard for number plates.
The British Standard sets the characteristics of the number plate. This includes visibility, strength and reflectivity. To meet British Standards, each number plate must be permanently and legibly marked with the following information.
The British Standard number (currently BS AU 145d)
The trademark or another way of identifying the manufacturer or supplier
The name and postcode of the supplying outlet
The first point is the key to the legality of stick on number plates “The British Standard number (currently BS AU 145d)”
What Is BS AU 145D?
In a nutshell BA AU 145D is a Specification of “Retroreflecting Number Plates” for the United Kingdom. In that specification, it sets out the design of UK number plates and how they should be made and the what properties the material they are made from should have. This includes a load of technical requirements including how to test the strength of the registration plate material. The specification of a UK number plate states that it must display the “BS AU 145D” marking to confirm that the manufacturer of the number plate tested it to BS AU145D standards and to legally display that, it must actually comply with the standard. You can’t just add it because it should be there. There are at least 9 tests a reg plate must pass to gain BS AU 145D standard.
How Could A Stick On Reg Plate Fail the Tests?
Generally, a stick on number plate is one that is made to have the back peeled off and stuck on the car like a decal or sticker, they are not made of thick plastic like a normal number plate. A sticker has no rigidity and would basically have similar properties to a piece of paper. One of the tests for a reg plate is “Resistance to bending”. Basically, the test involves hanging a 3kg weight on the reg plate 125mm from the clamp point and the plate must not bend more than 25mm. That is one test a stick on plate would surely fail even before the weight is added.
Another possible failure for a stick on plate is “Resistance To Impact”. This means a 1kg mass is dropped on the centre of the plate and it must not damage the face of the plate and then must still past a retroreflective test. Most stickers would simply ripe in this test. Then there is a vibration test which subjects the plate to 750 vibrations a minute to see if the plate disintegrates.
Would We Use a Stick On Number Plate?
We’d love to have a stick on number plate on our car as the reg plate holders on modern cars are just nasty looking, we also think that stick on plates that are designed to rip on removal would stop a lot of number plate theft, as removing them would destroy the plate, but sadly probably mean that the number plate would need to be professionally applied to increase the cost to the motorist. Also stick on plates are really easy to make, anyone with the correct material could just go round making reg plates and cloned plates would be a massive issue. So sadly for us, the front of the car shall remain ugly.
