Police figures show that the percentage of motorists caught drink-driving on UK roads rose this year.
Throughout June, officers stopped and breath-tested 88,629 drivers during a crackdown in England, Wales and Northern Ireland the Association of Chief Police officers (Acpo) said.
Of those, 5,373 (6.06%) tested positive, refused or failed a breath test, compared to 5.6% during the same period last year.
7.40% of drivers under the age of 25 were breaking the drink-drive law when they were pulled over, while 5.67% of motorists over 25 were offenders, revealed the figures.
During the month long targeted drink and drug driving campaign, police also ramped up testing for drivers under the influence of drugs, conducting 30% more field impairment tests than in 2010.
The crackdown resulted in 122 out of 337 motorists (36.20%) being arrested.
