40% of the UK's motorists think there should be a total ban on drinking before driving.
A recent survey by Direct Line car insurance has revealed that 34 per cent of motorists don’t know how many units of alcohol are in an average strength pint of beer or how that may affect their blood alcohol level, whilst 49 per cent are ignorant of the potency and effects of a large glass of wine.
And with 45 per cent of motorists admitting to driving after drinking some alcohol – and 4 per cent saying they do so ‘frequently’ – the confusion has serious consequences, with many people's ‘going out for a couple of drinks’ leading to a motoring conviction, an increased car insurance premium or, in a worst-case scenario, a serious road accident.
One of the reasons that many motorists are confused as to how much alcohol they are 'allowed' to drink before driving is because alcohol intake is measured in units, whilst the drink drive limit is measured by alcohol content within the blood, which can be affected by such factors as an individual’s size, weight and metabolism – which means there is no uniform measure.
