This year's Christmas anti-drink-drive campaign will see more drivers stopped than ever before, a senior police officer has said.
According to North Yorkshire Police deputy chief constable Adam Briggs, "it is only a matter of time before lawbreakers are caught".
He said: "Many people think they have to be involved in a collision or commit an offence to be stopped and breathalysed.
"This is not the case, and our aim is to test more drivers than ever before during this campaign."
He is determined to exceed the 183,397 stops during last year's campaign, and warns Christmas partygoers that many will still be over the limit the morning after.
The campaign runs from now until January 1, and will test for illegal drugs as well as alcohol.
In London, Metropolitan Police officers will be using new technology to help them build up a better profile of offenders.
Officers will record additional information such as the sex and age of offenders, as well as where they are caught, to fine-tune future operations.
