The number of people caught drink-driving in the run-up to Christmas in Northern Ireland has increased by more than 20 per cent over the same period last year.
The Police Service of Northern Ireland said the jump in figures was the result of a policy of "more robust enforcement" this year.
During the Christmas period, officers will be breathalysing every driver at the scene of every accident, no matter how minor.
The Christmas campaign began in late November, and in its first 11 days 710 drivers were breathalysed, 138 of whom failed.
The figure includes those motorists who were unfit to drive, or who were unable or refused to give a urine sample. In the same period last year, 113 drivers failed the breath test.
Almost a quarter of those found to be drink-driving were caught as a result of the new policy of compulsory testing.
Supt Ian Hamill, head of the PSNI Road Policing Development Branch, said: "Of the 138 drink-drivers detected so far, 34 were after collisions".
The PSNI was "committed to an uncompromising mix of enforcement" backed up by education through advertising campaigns.
Twelve of the drivers detected had more than three times the legal limit of alcohol in their bloodstream, while two were at almost five times the limit, Supt Hamill said.
About one quarter of all deaths on the North's roads has been attributed to drink-driving. To the end of October, 1,660 drink-drivers were detected, significantly less than the figure of 3,269 for all of 2000.
