Sir, The report (Oct 9) that new high-tech average-speed detection cameras are likely to be deployed initially on long rural A roads presents an opportunity to simplify current speed limits greatly.

A by no means unique example is a six-mile stretch of A road on the Isle of Anglesey that has speed limits of 30, 40, 60, 40, 30, 50, 60 and 30mph occurring quite randomly and illogically — only two of the 30mph stretches are through villages and most minor roads off the A road have 60mph limits. The multifarious speed-limit signs are often hidden by hedges.

The wider use of average speed cameras would provide an opportunity to simplify the present system of speed limits greatly by introducing a blanket speed limit of 50mph on all rural two or three-lane roads with a limit perhaps as low as 20mph through villages.

The present system of widely varying speed limits is totally illogical given that “crashes occur frequently but in many different places”.
