Dorset Police received 317 calls from the public about motorists believed to be driving under the influence of alcohol or drugs in December.
As a result officers attended 129 incidents, located 90 vehicles and made 36 arrests.
Every person contacting police received a follow-up call updating them on the police response during its ‘Festive Feedback’ campaign.
Overall, more than one third of the drink and drug drivers arrested during the month were as a result of members of the public contacting Dorset Police via 999 or 101.
Inspector Joe Wheable, of the Roads Policing Team, said: “The Festive Feedback initiative was all about improving public confidence and encouraging reporting to police by showing that we will respond to calls around drink and drug action and take positive action.
“The response from those we contacted was overwhelmingly positive, with people indicating that being updated on the outcome of their call made them feel involved in the process.
“They also stated that they felt the call was dealt with professionally and that they agreed with the response taken by police as a result of their contact.
“Not only has the Festive Feedback campaign encouraged members of the public to report incidents to us, it has also provided us with invaluable data to use for future operations and campaigns.
“We would like to thank the community of Dorset for their fantastic response to this campaign.”
Over the month of December Dorset Police conducted a total of 178 breath tests and 93 drug wipes.
