Mr. Donall O'Keeffe:

We do not give any advice on this. The legal limit is 50 mg and people should not get behind the wheel of a car if they are above that. A person's blood alcohol count is affected by age, sex, weight, whether one has eaten or is tired and one's physical and emotional condition. These all vary from person to person so the LVA and publicans do not issue any guidelines to members of the public or customers. We advise them not to drink and drive or to stay under the limit of 50 mg.
