ok ya sure they never just made a note of the reg as he passed as thats what there doig for bikes, if they cant see a reg then take a not of the plate and then nick ya.
theres no chance they can see the reg number on a tax disc, they might see a s/n but then i fold mine over to get out of parking tickets too anyway
they do right a note of the vehicle reg of all the cars who pass woith no plate speeding though
got mine off anyway just incase and keep the rear plate as dirty as possable
