The number of people caught drink or drug driving across the Angus, Dundee City and Perth & Kinross areas fell by 36 per cent over the festive period.
There were 16 people detected, compared to 25 for the same period last year.
A new lower drink drive limit of 50mg of alcohol per 100ml of blood came into force on December 5, coinciding with the launch of the four-week festive drink/drug drive initiative.
Inspector Brian Poole, head of Tayside Divisional Road Policing Unit said: “The reduction in the number of people drink-driving is welcomed and it appears that the introduction of the lower limit has refreshed, if not increased, awareness amongst the majority of the driving population that it is simply not worth taking the risk.
“Having said that, there are still too many people choosing to ignore the advice and get behind the wheel after consuming alcohol. In doing so, they are not only risking their own lives but also the lives of others within our communities.”
“This initiative has concluded, however our efforts in this area will continue.”
