Hmm i guess so, i remember having a bit of a, well i wouldnt say arguement, more of a differing view of the law with a cantankerous police officer regarding this whole numberplate mullarky back at the beginning of summer, my plates havent got the bsau number or makers name on them, well that was it, he started on about 60 quid this and on the spot fine that, to which i replied that while a plate missing this info would be illegal on quite a lot of cars, that it is not so on mine due to its age, he looked a bit puzzled and a couple of people who were with me agreed that yes my plates were legal, he ended up going back to his patrol car and reading through all the documentation, before having to back down because i was right, thats the first time i have ever gone up against a copper regarding a legal matter and not come off worse haha.
