One drink is 1 oz. of 80 proof liquor at 40%, 12 oz. of beer at 4.5 percent, or 4 oz. of wine at 12%.

KNOW YOUR LEGAL LIMIT
In Texas that means .08 percent of Blood Alcohol Content or any amount which results in loss of normal use of mental or physical facilities.  This is only a guide and not sufficiently accurate to be considered legal evidence.  The figures you calculate are averages.  Individuals may vary somewhat in their personal alcohol tolerance.   Food in the stomach affects the rate of absorption.  Medications, health, and psychological condition are also influential factors.  In any case, if you've been drinking at all, be careful!

THE SUREST POLICY IS . . . DON'T DRIVE AFTER DRINKING

Texas Commission on Alcohol and Drug Abuse --- Texas Alcoholic Beverage Commission


Another way to determine your Blood/Breath Alcohol Content (BAC) is to use The Intoximeters Inc. "Drink Wheel."   It is a form that you can fill out, and upon completion will instantly compute your estimated blood/breath alcohol concentration.
