Explanation
You are considered to be legally intoxicated when your blood alcohol concentration (BAC) is at least 0.08%. An average 180-pound man will reach a BAC of 0.10% from the alcohol in three standard drinks before his liver starts to break it down. One standard drink equals 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of hard liquor.
