Operation Anvil, which was launched in March and supported by the 95 Alive road safety partnership, has the sole aim of reducing deaths and serious injuries on the county's roads.

A police spokeswoman said that stopping more than 25,000 vehicles has led to the prosecution of more than 10,000 motorists for a number of offences including drink driving, speeding, driving while using a mobile phone, seat belt and insurance offences.

The campaign has also seen collisions resulting in serious injuries reduced by 29 per cent, fatal collisions reduced by 14 per cent and slight injuries reduced by 14 per cent.

The spokeswoman said the main reason for the campaign was to save lives, not just to prosecute motorists.

She said: "It is essential at this time of year, that motorists ensure they drive according to the road conditions and ensure their vehicle is in a safe and roadworthy condition, able to cope with the challenges posed by winter.

"Our enforcement campaign will continue into the winter months along with educational support from our partners within the 95 Alive Partnership."

So far Operation Anvil has seen 25,178 vehicles stopped and 10,391 prosecutions.

The full list includes:

* 4,528 speeding prosecutions

* 967 mobile phone offences

* 2,188 seatbelt offences

* 483 registration plate offences

* 206 prosecutions for no insurance

* 89 licence offences

* 1,930 other offences
