This is copyied from this link and my sticker plate meets all the requirements stated on this page so how it illegal?
"When replacing your number plate you should make sure that the correct material has been used to manufacture the plate. It should be made from a reflective material. Front number plates must display black characters on a white background and rear number plate must display black characters on a yellow background.
The Driver and Vehicle Licensing Agency^is not aware of any self-adhesive number plates that meet the British Standard requirements.^
Characters on a number plate can be 3D, providing they meet all the other requirements, but honeycomb or other background patterns are not allowed.
Also, the characters on a number plate need to be a standard height and width.
Your number plate should show the correct:
character height - 79 millimetres
character width - 50 millimetres (except the figure 1 or letter I)
character stroke - 14 millimetres
space between characters - 11 millimetres
space between groups - 33 millimetres
top, bottom and side margins - minimum 11 millimetres
space between vertical lines - 19 millimetres"
It does state that vehicle agency is not aware of self adesive number plates but mine was made by a registared company and is british standard marked so maybe direct.gov needs up dating.. If it was so illegal how come tvr could use this style plates on new cars
