Alcohol Impairment Charts for Women and Men
DISCLAIMER:
The results displayed on this web site are for general information purposes only. A person's actual Blood Alcohol Content (BAC) is dependent on many complex factors, including their physical condition, body composition, health, etc., and what they may have recently ingested including food, water, medications and other drugs. Only a qualified medical professional using sophisticated laboratory tests can accurately determine a person's Blood Alcohol Content for purposes of litigating DUI charges.
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's important to know how much and the concentration of alcohol you consume.
For 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. Therefore, women should refer to the female "Know Your Limits" chart.
Some states have 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.
These charts are intended as a guide, not a guarantee.
IMPAIRMENT BEGINS WITH YOUR FIRST DRINK.
