107 in Dumfries and Galloway have been stopped and breathalysed since the start of Police Scotland't festive drink driving campaign.
From Friday 6 December, when the scheme was launched, four people were found to be over the legal limit and now face prosecution.
Being convicted of a drink driving offence can result in anything from an automatic driving ban, a criminal record, a fine of up to £5,000 and, in some cases, a prison sentence.
“Already, sadly in this campaign we have detected four drivers who have chosen to ignore all the warnings that have gone out about this type of behaviour. Our patrols will continue to target those who choose to drink and drive and will deal with them as we deal with any criminal.”
– Inspector Neil Hewitson, Police Scotland's Road Policing Unit
People in Cumbria are being urged to call the police if they see anyone they've seen drinking attempting to drive home over the festive period.
Police say they will treat any tip offs as a priority and say the focus of this year's annual drink driving campaign is the responsibility of ordinary people to help keep the roads safe this Christmas.
The number of people in Dumfries and Galloway caught drink driving over the festive period has fallen by around a third, compared to last year.
From 3rd December to 3rd January, a total of 15 people were caught, eight less than over the same period last year.
"While it is pleasing to see a downturn in the numbers caught, 15 people were still willing to put their lives, and the lives of others at risk by taking to the road while under the influence of alcohol. It amazes me that people still think that it is acceptable to do this.
"The message is clear and always will be, drink and drive and we will catch you. While the festive campaign has come to an end, our patrols have not.
"We also urge the public in general to play their part to keep the phone calls coming in if they suspect someone is drink driving."
