Dorset Police have launched this year's drink and drug driving campaign - as drivers are warned not to put lives in danger.
During the Christmas period, there will be increased traffic patrols, along with road-side checks.
Every driver who is involved in a collision during December will be breath tested - irrespective of whether they are suspected of drink driving or not.
Inspector Matt Butler from Dorset Police's Traffic Unit said: "Drink driving is a priority for Dorset Police throughout the year and is one of the fatal four.
"We are taking the opportunity at Christmas time to remind people that putting your life, and the lives of others, in danger for the sake of a drink is really not worth it - so don't take the risk, don't drink and drive.
"If you're going out for a drink over the festive period, then plan ahead to make sure you can get home safely without having to drive.
"Take simple steps such as booking a taxi, having a designated driver in your group of friends or arranging overnight accommodation."
People caught drink driving could face a 12-month driving ban, a criminal record, up to six months in prison and a fine of up to £5,000.
Police will also use information submitted by the public to target suspected offenders.
"Research has shown that even one drink can impair the ability to drive, so my advice is simple - don't get behind the wheel after drinking any alcohol at all" added Inspector Butler.
"People forget that they could still be over the limit the morning after a night of drinking alcohol.
"Officers working on the 'no-excuse' project will also be focusing on drink and drug driving - as impaired driving is one of the 'fatal four' driving areas that the project's officers target.
"If a member of the public suspects someone is driving under the influence of alcohol or drugs, they should dial 999 immediately and report the details to the police so that we can intercept that vehicle."
