Around one in six drivers in Miller Road, Preston, was breaking the speed limit, during police checks last week.

Volunteers from the Community Road Watch Team spent an hour in Miller Road, Ribbleton, and Lea Road, Lea, on Friday, to check for speeding, seat belts and mobile phone offences.

Both sites are subject to 20mph limits with static speed cameras to encourage drivers to stick to the limit.

Out of 260 vehicles which passed through Miller Road, 33 (14%) were driving over the limit, with the top speed recorded at 40mph – twice the legal limit.

However in Lea Road only 13 out of 319 vehicles (4%) were driving too fast.

At each site, four vehicles were being driven without seat belts or appropriate child restraints.

A spokesman for Lancashire Police said: “Community Road Watch involves police working together with local communities at sites where people are worried about road safety.

“Community Road Watch teams monitor and record driver behaviour so that action can then be taken. This might include warning letters or police visits to motorists and ultimately, prosecutions.”

Drivers will be issued with warning letters following the operation.
