i got stopped on tuesday for mine (white on front, yellow on back..) he said he was going to fine me but i said i didnt know and had bought the car like that, so he just gave me a ticket i have to get signed by an MOT station once i have normal plates on and then send that off to avoid court proceedings...
anyhoo, on normal oned you can get them with the blue EU thingy at the side with GB or D etc unde the EU badge.. Are the german versions legal in UK? guessing not...
