I'm driving down a road in Grays, Essex today, lets say at slightly over the speed limit and heading west. There's a Gatso on the other side of the road that is obviously set up to trigger speeding vehicles heading east. Between the two lanes is a solid white line boxed chevron area about 4 feet wide. The only datum lines in the road are on the nearside of the lane that heads east, they aren't anywhere near the lane I am in, in fact they are about 20 feet to the offside of the centre line of my car. The camera flashes 4 times as I pass and the car behind me is too far away to have triggered the camera, so it appears I have. What I would like to know from someone with expert knowledge is whether or not they can bring a prosecution on the evidence they will have on the film.
