COUNTY Durham traffic police have launched a month-long crackdown on speeding drivers at known hot spots.

Crews are taking the force's mobile speed cameras to problem areas including routes such as the A67 at Darlington and the A690 at West Rainton, near Durham City.

Since the cameras were introduced three years ago police say speeds have fallen in some places, and the number of accidents reduced.

Between 1997 and last year, the number of cars breaking the 30mph limit on the A67 at Coniscliffe Road, Darlington, fell by almost 20 per cent.

Accidents on the A690 at West Rainton fell from 15 in 1997 to six last year. Accidents dropped from 12 to four on the A694 at Hamsterley, near Consett, and the toll on the A167 at Durham City and Darlington was halved.

Head of traffic, Superintendent Barry Peart, said: "In a sense, we hope to be unsuccessful in catching people speeding.

"But in reality we know some drivers go well above the speed limit, and the bottom line is that excess speed is a huge contributory factor in causing deaths and serious injuries on the roads.

"These campaigns are not about issuing as many fixed penalty tickets as possible.

"Our intention has always been to concentrate on education, not prosecution, and we think these campaigns have a long-term effect in persuading motorists to drive more carefully.''
