The percentage of people who were found to be driving under the influence, when tested by police in June 2015, was double compared to last year.
The annual summer drink and drug driving crackdown ran throughout June, and 501 people were breath-tested.
- 501 people tested - 181 tests administered after a collision
- 41 tested positive, or failed to provide a test - 23 following a collision
- That's 8%
That's double the percentage last year, however, around three times as many people were tested in 2014.
- 1,587 people tested
- 66 tested positive, or failed to provide a test - 16 following a collision
- That's 4%
Cumbria Police says the increase is down to the intelligence-led tests used by the force this year.
It was also the first campaign to test people suspected of driving under the influence of drugs.
