Technical note: These charts are not legal evidence of actual BAC. Although it is possible for anyone to exceed the designated limits, the charts have been constructed so that fewer than 5 persons in 100 will exceed these limits when drinking the stated amounts on an empty stomach. Actual values can vary by body type, sex, health status, and other factors.
Legend:
(.01%–.04%) Possible DUI—Definitely unlawful if under 21 years old
(.05%–.07%) Likely DUI—Definitely unlawful if under 21 years old
(.08% Up) Definitely DUI*

ALCOHOL IMPAIRMENT CHARTS
DRIVING UNDER THE INFLUENCE OF ALCOHOL AND/OR DRUGS /IS ILLEGAL*
There is no safe way to drive while under the influence. Even one drink can make you an unsafe driver.
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 ½-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.
