As for my front license plate its sitting nice and happy in the back pocket of my passenger seat only to be taken out and discretely slid in the front window of my car when i get pulled over.
But a couple weeks ago i got pulled over and forgot about the stupid thing and i was questioned about it, the cop walked around front and looked at my euro plate and told me it wasn't a legal plate... I asked him what if i kept the plate in the windshield he said no it has to be mounted on the front...
First off i think this is total BS and whats the actual law say, second how do warnings work do they actually stay in a computer data base that they can look up because he said if i get caught again he will eat my firstborn or something idk...
