Explanation

For drivers who are at least 21 years of age, the legal limit for blood alcohol concentration (BAC) is under 0.08%. If you are found to be driving with a BAC of 0.08% or above, you will be considered intoxicated and may be charged with driving under the influence (DUI). (Note: An average 180-pound man will reach a BAC of 0.10% from the alcohol in three 12-ounce cans of beer, three shots of 80-proof liquor, or 15 ounces of wine before his body starts to break down the alcohol.)
