Speeding County Durham drivers given warnings
More than 500 warning letters have been sent to drivers in a crackdown on speeding in County Durham.
The Community Speedwatch scheme involves volunteers monitoring traffic from roadsides.
It was started in the Spennymoor and Ferryhill areas in May after concern about speeding and since then 509 letters have been sent to motorists.
Durham police said they believed it was having a positive impact on driving in the area.
The volunteers use a speed indication display unit and record the details of any vehicles breaking the limit.
Durham police community support officer Adam Grundy said: "This initiative is having a positive impact on the drivers in our area and we're actively targeting repeat offenders with a view to prosecuting them."
