I was at traffic lights where two lanes went into one after the lights. The van on the inside was belching diesel so when the lights went green I accelerated very briskly to ensure I was in front of the van. Maximum speed would have exceeded the speed limit (by 10-15 MPH) very briefly. Twenty yards back before the traffic lights was one of those combined cameras (red light and speed). I assume that the camera was a radar one and not the one using strips in the road so could the camera snap me even though I was at least 50 yards past it by the time I exceeded the limit?
