Estimated Blood Alcohol Content / BAC

Any Alcohol Consumption May Cause Impairment

  1. Count your drinks (1 drink = 1 oz 100-proof liquor, 1 five oz glass of table wine or 1 12 oz beer).

  2. Use the chart and under number of "drinks" and opposite "body weight" find the percent of BAC.

  3. Subtract from this number the percent of alcohol "burned up" during the time elapsed since your first drink. This figure is approximately .015% per hour. (Example: 180 lb. man - 8 drinks in 4 hours / .167% minus (.015x4) = .107 %
