I recently received a dubious speeding ticket from the RCMP on highway 99 (sea-to-sky-highway). I intend to dispute the ticket. This officer was in front of me on the highway just before Squamish where the speed limit changes from 80 to 50Km/h. He pulls over as I am slowing down, breaks, pulls in behind me and of course lights me up after only following me for about 200 yards. What I find somewhat troubling is he used an [L] plate on the car. Is this entrapment and use of a provincial sticker illegally? What distance do the police have to tail you to determine your speed in this sort of circumstances?
