Police charged 155 people with drink driving offences during a December campaign, it has been revealed.
And many of those were caught after tip-offs from the public.
But West Yorkshire officers say this was a significant reduction compared to the previous year when 183 people were charged.
Of those charged: 124 were men and 31 were women charged for drink driving offences
* Two men were charged with driving under the influence of drugs
* The most common age range for those charged was 25 - 34 years old
Police had urged people to report suspected offences under their “dob in a drunk driver” initiative.
Insp Joanne Field, who leads West Yorkshire Police’s Roads Policing Unit, said: “We would like to thank concerned members of the public who reported drivers who they suspected were under the influence of drugs or alcohol.
“We offered them an easy and efficient way to report drivers they believed to be affected by alcohol or drugs and this seems to have made potential offenders think twice before getting behind the wheel over the festive period.
“The number of drink driving charges is decreasing nationally which is a step in the right direction – this could be that we have been constantly reminding people about the consequences, or people have decided that it is simply not worth the risk.
“We are still concerned about the number of young people who have been charged. Drink driving can have devastating consequences for the person behind the wheel and for other drivers on the roads or pedestrians.
“We are extremely pleased to see a drop in the figures a year on and we hope that the public will continue to support this campaign throughout the rest of the year to help us do everything we can to deter people from driving under the influence.”
