Alcohol
Impairment Chart
This
chart is intended as a guide,
not a guarantee.
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 1.25 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.
IMPAIRMENT
BEGINS WITH YOUR FIRST DRINK.
FOR SAFETY'S SAKE, NEVER DRIVE
AFTER DRINKING!
