EVERY driver involved in a crash on Dorset's roads this December will be breath tested - whether police believe they have been drink-driving or not.

That is the reminder for motorists today as Dorset Police launch their annual Christmas anti-drink and drug driving campaign.

There will be increased patrols across the county during the festive period and police are urging the public to make other travel arrangements if they plan on drinking.

Chief Inspector Rick Dowell, head of the road policing unit, said: "Drivers who choose to drink and then get behind the wheel are completely irresponsible and a real danger to innocent road users.

"Our message is simple - there is no justification for endangering your lives or the lives of responsible road users by driving after consuming alcohol or taking drugs at any time of the year."

During the 2005 campaign 204 motorists were arrested. Last year 198 arrests were made.

The public are again being asked to help make the county's roads safer by contacting Dorset Police if they suspect someone is driving under the influence of drink or drugs.

"We have had excellent support from the public during previous campaigns," Chief Inspector Dowell said.

"During the summer campaign 28 arrests were made as a direct result of calls made by the public to Dorset Police. Working with the communities is helping us to ensure that these dangerous and irresponsible drivers are taken off the roads, making Dorset a safer place."

Dorset Police are encouraging people going out during the festive period to avoid driving by booking a taxi in advance, using public transport or staying overnight if possible.

They are also urging revellers to refuse to get into any vehicle if the driver has been drinking and to never offer an alcoholic drink to someone who is driving.

Chief Inspector Dowell added: "Remember - there is a real risk of being over the limit the morning after you have been out drinking."

The campaign runs until Tuesday, January 1. Anyone who suspects someone is driving under the influence should dial 999 immediately.
