NIP today - 41 mph in a 30 - I think I know the stretch and I was obviously obeying a non-existant 40 limit. I take objection to points when it's a mistake! (In fact they want to know who was driving, I've asked for a photo to help my recall, will they send one?) If I fit a mobile camera detector will it alert me before they have a fix? Are detectors legal? Links appreciated. John
