In general everyone knows that alcohol, whatever the quantity, slows down a persons reaction time, impairing their judgement of speed and distance. But what most people don't know is that of those people caught drink driving each year, many of them hadn't jumped into their car after a night out. Most were driving the following morning, unaware of still being over the legal drink drive limit.
Take a look at this alcohol calculator and see how drinks could put you over the limit for between 13-21 hours.
- Four pints of strong lager - you should not drive for at least 13 hours after your last drink.
- Five large bottles of beer - you should not drive for at least 16 hours after your last drink.
- Three 250ml glasses of wine (15% volume) - you should not drive for at least 13 hours after your last drink.
- Five super strength cans - you should not drive for at least 21 hours after your last drink.
Many of the functions needed to drive safely are affected when drinking alcohol: the brain takes longer to receive messages from the eyes making it difficult to process of information. It also slows reaction times, so stopping quickly may be harder.
