Drink-driving detections fall by 50%

The number of motorists detected driving under the influence of alcohol has fallen by more than 50% over the past five years, with a record low number of drink-driving offences likely to be recorded in 2012.

In 2007, one in every 25 motorists tested for drink- driving was found over the legal blood-alcohol limit.

However, the figure is close to just one motorist in 50 tests since 2011.
