Police stopped and breathalysed more than 1,000 drivers last month.
And they made 265 arrests and charged 171 people with a drink driving offence as part of West Yorkshire Police’s annual campaign to target drink and drug driving.
Another six people took field impairment tests to see if they were driving under the influence of drugs – two of them were arrested.
Chief Inspector Mark Bownass, head of the Road Policing Unit, said: “People who drink more than the legal limit of alcohol or take drugs, and then choose to drive, put their lives at risk along with those of their passengers, pedestrians and other people on the roads.
“Although we run a targeted campaign in December, driving under the influence is something we prioritise all year round as we have seen first hand the devastation it can cause.
“Our priority is to improve road safety and avoid unnecessary casualties. Our message to anyone who is thinking about having another drink or taking drugs before getting behind the wheel is that they could face a prison sentence and a lifetime of regret because they have hurt or killed someone as a result of their actions.”
