Never been done in 25 years driving. But coming back from Leicester the other weekend an accident forced us off the motorway onto local roads. Not knowing the area and trying to navigate a route home I missed a sign that said the road was a 20 mph road. Only when I saw a great big white 20 on the road did I realise, which was at the same point the camera flashed me.
I had seen the camera in plenty of time which is the annoying thing as I am being done for a speed of 28mph in a 20 zone!
I can't appeal it as I am in the wrong. Just got to send the letter back and see if it's a fine and points... a court date or maybe send me on one of those speed awareness courses.
