my point is :
dvla are considering revoking plates thar are illegal if stopped. they would require photgraphic evidence to show they are legal.
basically :
if they are given £30 ticket by police, and photo taken, this info is sent to dvla.if a second ticket is issued then dvla may revoke the registration plate, thus meaning you couldnt drive it on the road.
its a new system and so will have issues, but for the worst offendings it could help.
personally i have neded to stop and interogate the plate to ascertai correct plate.
just thought i'd let you know, pass the word like. its the advice i'll be passing on in my pfofessional role.
