The number of people caught drink driving in Lancashire has fallen for the third year in a row, police said.
Officers stopped tested 8,923 drivers during a summer campaign in June. Of those, 237 failed or refused to take the test.
In the same period last year they stopped 6,164 drivers, and 214 failed or refused a test.
Of those tested, 2.6% failed last month, compared to 3.4% at the same time in 2009.
People under 25 accounted for one third of the failures or refusals.
Insp Martin Bishop, of Lancashire police, said he was pleased by the reduction but admitted "there is still a problem among certain drivers".
He added: "We are encouraged by the results, especially as we carried out more breath tests this year but had less people failing or refusing.
"We continue to take this issue seriously and will continue to crackdown on drink and drug driving."
