They're joined by community volunteers
Devon and Cornwall police are having a week-long crackdown on speeding motorists.
Hundreds of volunteers from community speedwatch teams are joining them as part of road safety week, organised by national charity Brake.
Across the UK, police figures show that travelling too fast or exceeding the speed limit was a contributory factor in 25 per cent of deaths where an officer attended the scene of a collision.
Adrian Leisk, Head of Road Safety for Devon & Cornwall Police, is also chair of the Vision Zero South West enforcement group. He said: “We know speed is a contributory factor in many serious and fatal collisions – it gives you less time to react and significantly increases your chances of being killed or seriously injured in the event of a crash.
“To support Road Safety Week, we will be mobilising officers and volunteers to monitor lots of different roads across the two counties – including some places where you may not have seen us before - so please don’t get caught out.
“Speed enforcement is not there to make money – it is there to protect road users and keep people safe by ensuring motorists adhere to speed limits.”
Ross Moorlock, Interim CEO at Brake, said: “Every time we drive faster than the speed limit, or too fast for the road conditions, we increase the risk of a crash – and we increase the chance that someone will be killed or hurt on the road. The faster you go, the longer the stopping distance and the harder you will hit something.
“Whoever you are, and however you travel – this year we are challenging everyone to start talking about speed with your friends, families and colleagues.”
