DANGEROUS motorists could be rumbled by text message as police start a summer campaign clamping down on drink and drug drivers.

People will be able to tip-off police about those they suspect will drink or take drugs and drive via text message.

Operation Tonic officers will also be on the lookout for those tweeting or using social networking sites at the wheel - an offence which can see drivers banned.

The scheme sees people text the word ‘drunk’ to 81819 to tell police about someone who has got behind the wheel under the influence of drink or drugs.

The text service was previously run over Christmas, when the force received a total of 50 texts about dangerous drivers.

Chief Insp Yannis Georgiou of Avon and Somerset’s Roads Policing Unit said: “Drink and drug driving is totally unacceptable and is a serious crime. We work to tackle drink and drug driving all year round, not just in our summer and Christmas campaigns.

“If you drink alcohol or take drugs and drive, you put yourself, your loved ones and other road users at risk.

“We were really encouraged by the number of people who called in over the Christmas period.

“Our message remains the same – don’t drink and drive.”
