Alcohol affects individuals differently. Your blood alcohol level may be affected by your age, gender, physical
condition, amount of food consumed, and any drugs or medication. In addition, different drinks may contain different
amounts of alcohol, so it is important to know how much and the concentration of alcohol you consume.
For the purposes of this guide:
“One drink” is equal to 1.5 oz. of 80 proof liquor, 12 oz. of regular beer, or 5 oz. of table wine.
A woman drinking an equal amount of alcohol in the same period of time as a man of an equivalent weight may have a
higher blood alcohol level than that man. Women should refer to the Alcohol Impairment Chart for Women.
Connecticut has set .08% Blood Alcohol Concentration (BAC) as the legal limit for Driving Under the Influence.
For commercial drivers, a BAC of .04% can result in a DUI conviction nationwide.
