Welsh police officers tested over 35,000 motorists as part of the 2012 All Wales Winter Anti Drink/Drug Drive Campaign an increase of over 7,700 compared to 2011.
The four week campaign ran from 1st December 2012 to 1st January 2013.
The large number breath tests administered during the campaign resulted in 502 being positive, failed or refused, a drop of 43 compared to 2011.
The under 25 age group remains the same with 142 young drivers being arrested.
The campaign which was led by South Wales Police was launched at the All Nations Centre, Sachville Avenue, The Heath, Cardiff, on Tuesday 27th November 2012.
South Wales Police Road Safety Manager Wayne Tucker said:
“Although there has been a marked increase in testing across Wales, it is still disappointing to see that some drivers are continuing to risk their lives and those of others by consuming alcohol and then getting behind the wheel of a vehicle.
“It is evident from the results that a majority of drivers across Wales are responsible and law abiding, however it is still disappointing to see a minority who are continuing to ignore the law.
“It cannot be stressed highly enough that any amount of drugs or alcohol can impair a person’s ability to judge speed and distance, and inevitably endanger the lives of other motorists.”
Mr Tucker added:
“Our continued message is plain and simple what ever the time of year drug and drink driving will not be tolerated, and that we will continue to treat these offences as socially unacceptable as well as a criminal offence.
“Across Wales officers will continue to treat this issue seriously and using intelligence led policing will continue to target areas where drink driving is prevalent.”
