Frequently Asked Questions

How much alcohol can I drink and not be over the limit to drive?

It is not advisable to have even one alcoholic drink before driving as alcohol impairs your judgement and lessens your reflexes.

The only safe limit of alcohol to have in your blood and drive is zero.

The official amount of alcohol is 35 microgrammes per 100ml of breath. But this cannot be translated into an exact amount of units as every person is different and levels will be affected by a number of factors including the person's height, weight, and the time they had their last drink. The best advice is not to drink at all or order a taxi.
