Surveys of the public also show a consistently high degree of support for a lower limit.
The UK legal limit was set in 1967 at a level where impairment was undeniable - 80 milligrams of alcohol for 100 millilitres of blood (0.8). Recent research suggests that impairment begins at 0.5 and lowering the limit could save at least 40 lives a year on Britain’s roads. We are now out of step with the rest of Europe where most countries have adopted the lower limit of 0.5. 220 people were killed in drink drive accidents in 2015 and the total number of collisions and accidents where at least one driver was over the alcohol limit rose by 2% to 5,740. Long term alcohol related incidents have been flat lining for the last eight years - 13%, or around one in seven, of all fatal crashes involved alcohol in 2018.
Research shows that drink driving is most common amongst young drivers and the middle aged and police still catch thousands of drivers over the limit across the UK every year. Most were stopped by routine patrols rather than as the result of a crash.
IAM RoadSmart acknowledges that a lower limit could risk diverting police resources from catching the most dangerous offenders who pay little regard to any limit, but it would also send a very powerful signal on drinking and driving. For the moment, the government is committed to keeping the current legal limit of 0.8 but this approach can only work if there is vigorous and focused enforcement on drink driving. Given the recent cuts in police budgets and the lack of improvement in drink related deaths it is clear the battle has been not yet been won and the ‘status quo’ is not good enough.
