The campaign will run throughout August and focus on roads which have seen speed-related collisions or roads where residents have complained of excessive speeding.

Chief Superintendent Lynn Harris, head of Operations Division, said: "We want to warn all drivers and riders to expect an increase in police speed enforcement activity.

"All our officers will be making the maximum use of our speed enforcement equipment.

"There can be no doubt that exceeding the speed limit or simply driving too fast for the road conditions is a contributory cause of many road collisions.

"The higher the speed, the more likely the risk of serious or fatal injury. That is why we have given priority to the enforcement of speed limits as part of our road safety strategy.

"Although it is an all-year round priority, we do conduct speed enforcement campaigns which are designed to draw attention to the misery that can be caused by excessive speed."

Motorists found to be breaking the speed limit can be issued with a £60 fixed penalty notice and three points on their licence.
