Travelling eastbound on the A406 last night having joined it at Chiswick roundabout from the A4. This patch of the A406 is 40MPH. Coming up to the first camera, a newly fitted camera may I add, switching lanes whilst maintaining 40MPH, the camera flashes 3 times (or maybe twice). Should I expect to hear from the DVLA? If so, can I prove I was doing the limit?
