Last night we got flashed doing 55 in a 60. I checked the signs again after it flashed (only flashed once) and my husband checked his speedo again. We were pulling an empty trailer so no way we would have been speeding anyway, it bounces too much. We pulled over a bit further down the road by a road sign and I took a photo of the car with the trailer on using my mobile. Really can't be doing with a speeding fine when we weren't even speeding (would take it on the chin if we had). What do we do if we get a letter? (It would be my husband as he was driving, but I was as shocked as him when the camera flashed).
