Drink Driving

Drink driving

Any amount of alcohol can affect your ability to drive a car safely. If you are driving, don't take the risk.

Many people may still be under the influence of alcohol the next day. It is impossible to calculate your limit and exactly when it is safe to drive again the next day so don't even try.

If in doubt, don't take the risk, don't drink and drive.

The drink drive limit

The current legal limit is:

  • 35 micrograms of alcohol in 100 millilitres of breath, or
  • 80 milligrams of alcohol in 100 millilitres of blood, or
  • 107 milligrams of alcohol in 100 millilitres of urine.

If you are twice the legal limit statistics show you are at least 50 times more likely to be involved in a fatal collision than a driver who hasn’t been drinking and at least 30 times more likely to cause a crash.


If you are convicted of drink driving you will:

  • Lose your licence for at least a year
  • Have a criminal record
  • Face up to six months in prison
  • Face a fine of up to £5,000
  • Risk losing your job
  • See your car insurance costs soar once you get your licence back.

Those are just the things that will affect you directly. Unfortunately, many drink-drivers kill innocent people as a result of their actions. If you are convicted of causing death by careless driving while under the influence of drink you may be given:

  • Up to 14 years in prison
  • An unlimited fine
  • A minimum two-year driving ban
  • A mandatory extended driving test.


It is impossible to calculate your alcohol limit. It depends on a variety of factors, including what you are drinking, your weight, sex, age, and metabolism.

Drinking any amount of alcohol impairs your driving. The only way to remove the risk is to not drink any alcohol at all.

Before drinking:

  • If you are out, think about how you will get home
  • Do not drive to the venue – you may be tempted to drive home after drinking
  • Drink soft drinks until you get home
  • Nominate someone to drive
  • Book a taxi or find out what public transport is available
  • Never offer an alcoholic drink to someone who you know is driving.

It takes time to get the alcohol out of the system and contrary to popular myth, cold showers and black coffee do not sober you up any quicker. You may still be over the limit the morning after consuming alcohol, your driving will still be impaired and you still risk losing your licence, more importantly, you risk killing yourself or someone else.
