More than 9,000 motorists were arrested in England and Wales for drink-driving during the festive period.
The Association of Chief Police Officers (ACPO) said there were 133,136 drivers tested over four weeks, of whom just under 7% tested positive (9,275).
The proportion of motorists found to be over the limit after an accident was 8.6% of those tested, or 1,344, slightly down from 8.75% last year.
For the first time, ACPO revealed how many drivers had been arrested for drug-driving during Christmas and New Year.
Officers administered "fit to drive" roadside tests on 540 motorists suspected of being impaired by illegal drugs, leading to the arrest of 178 people, or 33% of those tested.
ACPO said the figures showed that drivers continued to drive under the influence of drink and drugs despite the "substantial and well-publicised risk" to themselves, pedestrians and other road users.
It is the first time ACPO has published the total number of breath tests administered - normally the organisation only releases the number of tests after a collision.
