A drink-driving crackdown across the district has been declared a success by police.
From the 571 motorists stopped during Operation Ovaldale, which ran from December to January in Calderdale and Bradford, a total of nine were found to be over the drink drive limit.
Operation Ovaldale involved police conducting morning and evening checks, carrying out tests where appropriate on those suspected of drink driving or being under the influence of drugs.
Last year in a similar operation, 12 people were arrested from 509 stops.
PC Andrew Gudgeon from the Western Area Roads Policing Unit, which covers the two policing districts, said the figures were encouraging.
“Despite making more checks than in the same period last year, we are pleased to report that fewer people were over the drink drive limit,” he said.
“But although the message seems to have been heeded by many, there were still nine motorists who risked their own lives and those of other road users by getting behind the wheel after consuming alcohol.
“Drnk driving can have life-altering consequences. You’ll be banned from driving for at least 12 months and this could mean losing your job and having your family life disrupted.
“But if you were found guilty of causing death by careless driving while under the influence of drink or drugs you could be looking at 14 years in prison.
“Don’t drink and drive - it simply isn’t worth it.”
