Fewer drivers involved in collisions failed roadside breath tests this year during Nottinghamshire Police’s annual summer drink and drug drive campaign.
More than 1,500 tests were carried out in June, with 158 arrests made for failing or refusing to give breath tests.
That figure included 388 drivers who were tested following collisions.
Only 20 failed tests, a ratio of around one in 19. In June last year, the ratio was one in ten, when 42 out of 444 failed tests following collisions.
