As my registration number is a 'cherished plate' some 20 years old now, I use the original rear number plate from the first car it was affixed to, on trailers and recent cars. I changed the original plates on that particular car for what are now called 'show plates', that as the actual car is that age are still legal. :side: :side:
Which just goes to show what a nonsense the number plate law is. As long as ANPR can pick up the digits that form the registration, the rest of the info supposedly required is superfluous. ANPR is how plod tracks vehicles, not the BS code, the seller or the reflectiveness of the plate.
There was similar stupidity in the law around registration numbers sold by wotevrer the DVLA used to be called when they sold 'personal registrations', as certified and receipted and were your property. At that time you bought a 'personal registration' that strangely was personal. Then at some point they changed to 'cherished numbers' that were not your property. Then they could only be used on a SORN'd vehicle for 1 year, but they didn't tell you when you SORNed the vehicle for the 3rd consecutive year to meet the SORN requirement, that came in after you had bought the 'personal registration' that then prevented you transferring your 'personal registration' that had then come a 'cherished number', that wasn't your property despite being sold and receipted as such. I challenged DVLA and got the law changed due to the misselling of a product by DVLA. You can now SORN a 'cherished number' on a vehicle for 5 years. Sometimes those employed by the authorities have too much time on their hands to dream up some things
