A drunk driver in Ilkeston was caught when a member of the public called police after seeing him down several alcoholic drinks before getting behind the wheel on leaving Morley Hayes Golf Club.
Officers responded to the call and stopped a man in his 30s who gave a positive breath test. He was arrested and later charged with drink-driving.
He was one of 79 people who gave a positive test, refused to take it or failed to provide a sample.
During December 2013 Derbyshire police worked with Crimestoppers who offered a reward of up to £1,000 to anyone who reported a drink-driver. leading to a charge.
Chief Insp Steve Wilson said: “Crucially, no one has yet applied for the reward which shows that the public report drink-drivers out of a moral duty rather than for financial gain.
“The results this year show a five per cent drop in positive tests compared to last year. However, one drink-driver is too many and we will continue to target those who put themselves and other road users at risk.”
