I was caught by a mobile speed camera on the A3. It was less than 1/4 mile after a fixed camera. Is this legal to have two speed traps so close?
The police can position speed cameras wherever they feel is appropriate. They rely on the fact that people will speed up after they gone past the first one!
So as long as the evidence from the camera is accurate and reliable you can be convicted.
What’s the speed alleged? Were you caught by both cameras? Have you got any penalty points already?
