The number of motorists arrested during the Dorset Police's Christmas drink-driving campaign has fallen by 25 per cent.
During December, 100 people were arrested - compared with 1343 arrests made the previous year.
Of those arrested, 79 were men - while 21 were women. Over half arrested were between the age of 25 and 50.
Traffic Sergeant Joe Pardy said: "It is encouraging to see that the number of drivers risking their lives, and the lives of other road users, by choosing to drink and drive over the festive season has reduced.
"Most of the motorists stopped were very supportive of the officers' actions and fully supported the campaign to reduce road casualties.
"The message seems to be getting across to the people of Dorset that drinking and driving is dangerous and just not worth the risk."
Every driver involved in a collision between December 1 and Janaury 1 was breath tested, irrespective of whether they were suspected of drink driving or not.
There was also an increase in traffic patrols and roada-side checks.
Members of the public are urged to call Dorset Police is they suspect someone is driving under the influence of drink or drugs.
