California Driver Handbook
Text Alternative for BAC/DUI Chart
Drinking alcohol affects your Blood Alcohol Concentration (BAC). It is illegal to drive with a BAC that is .08% or more (.04% or more if you drive commercial vehicles; .01% or more if under 21). However, a BAC below .08% does not mean that it is safe or legal to drive. The charts below show the BAC zones for various numbers of drinks and time periods. Remember: “One drink” is a 1 1/2-ounce shot of 80-proof liquor (even if mixed with non-alcoholic drinks), a 5-ounce glass of 12% wine, or a 12-ounce glass of 5% beer. These “one drink” equivalents change if you are drinking ale, malt liquors, fortified wines, port, brandy, different proof liquor, or if you are drinking on an empty stomach, are tired, sick, upset, or have taken medicines or drugs.
