More than 400 drivers were arrested for drink or drug driving during a recent All Wales campaign, which ran throughout December.
Led by North Wales Police, the 2017 festive campaign was part of a wider clamp down on those driving while under the influence.
The total number of 438 arrests was down on the 2016 festive campaign, when 478 drivers either tested positive, refused or failed a drink drive test, and 151 tested positive for drugs.
South Wales Police – who used an ‘intelligence-led approach’ – recorded the highest number of arrests in 2017, catching 207 offenders.
As part of the campaign, North Wales Police distributed free disposable breath test kits for anyone who wanted an indication of alcohol levels the morning after a night of drinking.
In Gwent, police launched a new text service allowing the public to provide details of motorists who drive under the influence of drugs or alcohol.
Chief inspector Daryl Fahey, South Wales Police, said : “Policing operations and campaigns are an important part of protecting road users and vulnerable members of our communities.
“The All Wales Drink Drug Drive Campaign is an opportunity for police forces to highlight this important issue which we carry out as part of our everyday policing 365 days of the year.
“The results provide our communities with reassurance that we are working with our partners and local groups to ensure our roads continue to be a safe place. It also sends a strong messages to all road users that driving under the influence can have devastating consequences for all those involved.
“It’s disappointing to see that a proportion of drivers are continuing to risk their lives and others by getting behind the wheel under the influence of alcohol or drugs.”
