A recent survey of Londoners, carried out by YouGov, found that 30% have admitted to drinking and driving. That figure doesn’t tell us how much those people had drunk before they got behind the wheel, but it’s interesting to note that 10% considered themselves to be safe to drink after three or more alcoholic drinks.

It’s hard to say exactly how many units this would add up to – or how many units it would take to push any given person over the drink drive limit – but three alcoholic drinks could be up to as much as around 6 units. This suggests that many people are still drinking too much before getting into the car and driving, while others might be just on the limit.

Of course, drinking and driving is never recommended and you should also be careful the morning after, too – 22% of people questioned in the survey reported driving the morning after despite suspecting they might still be over the limit. If you do find yourself in the position of being charged with drink driving a specialist lawyer is essential. By looking at the papers in relation to the case we can give you some idea of whether there may be a defence to the charge.
