The only safe alcohol level is Zero

There is no safe drink drive limit so if you are going to drink then make sure you have organised a way to get home be that a designated non drinker, use public transport or a taxi.

Many of us would never knowingly drink and drive but are unaware of the dangers of being under the influence if you have been drinking the night before It will take over 12 hours for the alcohol in 6 pints of ‘normal’ strength beer to leave your body.

The legal ‘limit’ is 35 micrograms per 100ml of breath or 80 milligrams per 100ml of blood however, it is very difficult to translate this in terms of drink consumed- it will vary from person to person depending on your gender, age, state of health, tiredness, weight, amount of food you have eaten etc.

Units were introduced to help us understand how much we are drinking and the affects it can have on our health. They can also help us estimate how long alcohol will be in our system for and help us drive with only a Zero alcohol level.

1 unit of alcohol is

    • ½ pint of normal strength beer, lager or cider (3-4% alcohol by volume)
    • 1 small glass of wine (100 – 125ml)
    • 1 measure of sherry or port (50ml)
    • 1 pub measure of spirits (25ml)

It takes roughly one hour for the first unit of alcohol to enter your system and then one hour per unit after that, so the six pints of normal strength beer we mentioned earlier will take 12 hours per unit and 1 additional hour to clear your body. This is a minimum estimation and not a guarantee.


Causing death by careless driving while under the influence of drink or drugs can result in a jail term of up to 14 years, not to mention having to live with the knowledge that you have killed or injured another person and it was totally avoidable.

Being caught drink driving can have serious consequences.

You will be disqualified from driving for a minimum of 12 months and even go to jail for up to 6 months and be given a fine of up to £5,000.  As well as the increased costs of alternative transport you could also loose your job - your home - your family.  Your insurance costs will increase and it could make hiring a car extremely difficult for about 10 years.

Even being in charge of a vehicle with excess alcohol could result in a prison sentence of up to 3 months, a driving ban and a fine of up to £2,500
