just got one in my post this mornig it says i was doing 41 in a 30 zone .on a road which i use every day .and i know there is a speed camera there . and every time iam that bit of road i always watch my speed when aproching the camera.they got my reg right and the date and time but i know that i was not speeding trough those cameras on that day in question .as any body ever contest a speeding ticket and won. How do I stand if I contest this? I need to see video evidence of me doing that speed
