Alcohol can affect each person in a different way.  The way your body reacts to alcohol depends on your gender, how much you weigh, how quickly you drink and whether or not you have eaten.  You also need to remember that drinks may contain different amounts of alcohol. 

For purposes of this chart, "one drink" is equal to:

• 1.5 oz. of 80 proof liquor (Distilled spirits)
• 12 oz. of regular beer or
• 5 oz. of table wine

Females reach a higher BAC level faster than males of the same weight.  A woman should use the female version on the chart that is highlighted in pink.

Pennsylvania has set .08% BAC as the legal limit for a Driving Under the Influence (DUI) conviction.  Commercial drivers can be convicted of a DUI nationwide with a BAC level of .04%.  You may be convicted of DUI at .05% and above if there is supporting evidence of driving impairment.

The Zero Tolerance Law (Section 3802e of the PA Vehicle Code) lowered the Blood Alcohol Content (BAC) for minors (persons under 21) to .02%.

REMEMBER:

• A person must be 21 years of age or older to legally purchase, attempt to purchase, possess, consume, or transport any alcohol, liquor, malt or brewed beverages. 
• Impairment begins with the first drink - the only safe driving limit is .00%.
• For safety's sake, never drive after drinking!
