A recent study by the Office for National Statistics reported that almost 5% of female motorists drove while over the legal limit last year.

With 18.8 million female driving licence holders across the UK, that would mean that in 2020, around 870,000 women drivers got behind the wheel at least once while under the influence of alcohol.

Data shows that one in five drink-drive accidents involve a female driver who is over the limit. 2018 saw 1,640 casualties on Britain’s roads caused by female drink-drivers, including 20 deaths.

In England, Wales and Northern Ireland, the legal driving limit is 80mg of alcohol per 100ml of blood – 0.08% blood alcohol content (BAC).

In a recent survey, over a third of women believe that their ability to drive is only impaired if they are actually over the drink-drive limit.

In actual fact, research shows that motorists are 13 times more likely to be involved in a fatal collision when at the drink-driving limit. Even when driving with just 10mg per 100ml of alcohol in the blood (just one eighth of the limit), motorists are still 37% more likely to be involved in a fatal crash.

Even a very small amount of alcohol can slow down your reaction speed, inhibit judgement and reduce concentration and coordination – all of which could increase the likelihood of an accident.

For those planning to drive around the UK, it’s worth taking some time to understand the differences between Scotland’s drink-drive limit, when compared with England, Wales, and Northern Ireland.

It’s also important to understand that drink-driving limits are not an exact science. Your BAC can vary depending on your age, gender, weight, metabolism, and many other factors. The type of alcohol you drink can also determine whether you stay below the legal limit.
