What does the law say?

Laws about purchasing alcohol vary by country. Under British law, alcoholic beverages can be sold to anyone over the age of 18. 

The legal limit for driving in the UK is:

  • 35 micrograms of alcohol per 100 millilitres of breath.
  • 80 milligrams per 100 millilitres of blood.
  • 107 milligrams per 100 millilitres of urine.

There is no definitive way for someone to work out whether they are over the limit or decide how much it will be safe for them to drink before driving. How much alcohol one can safely consume depends on many factors: age, sex, weight, metabolism, how much food you have eaten, stress levels, type of alcohol drunk.

Due to the numerous calculations and measurements that would be required to work out your ability to drink a little and drive, the safest option is not to drink at all, and never offer a drink to someone else who you know to be driving. Any alcohol, even a small drink, will impair driving ability and the only safe course is not to drink any alcohol prior to driving.
