Speed limit signs
Length of road where two cameras are used to measure the average speed of a vehicle between two points
What it means
Your speed is averaged between two camera points, so lifting off just for the camera achieves nothing - the whole section counts. You will see these through long roadworks and on some rural A-roads. Settle at a steady speed at or under the limit and hold it right to the end of the section.
