The breathalyser accident prevention tool is celebrating its 40th anniversary of being used by police this week.
When it was first introduced on October 9th 1967, there were 13,000 alcohol-related accidents on the road.
In 1987, this figure was down to 6,800, while last year it was at 2,500.
However, the Royal Society for the Prevention of Accidents (RoSPA) has commented that drink-driving regulation needs to be reassessed in order to save more lives.
"RoSPA is calling for the drink-drive limit to be reduced to 50mg of alcohol per 100ml of blood – a move which would save around 65 lives and 230 serious injuries on Britain’s roads each year," said Kevin Clinton, RoSPA head of road safety.
The Department for Transport has revealed that there were 3,150 deaths on roads in the UK during 2006, down from the 3,201 recorded in 2005.
