Use this calculator to estimate just how little alcohol it takes to put you on the “wrong side of the law”.
Blood Alcohol Content (BAC) Calculator
Note: There is no blood alcohol calculator that is 100% accurate because of the number of factors that come into play regarding the consumption and reduction (burn-off) rates of different people. Factors include the sex (male/female) of the drinker, differing metabolism rates, various health issues and the combination of medications that might be taken, drinking frequency, amount of food in the stomach and small intestine and when it was eaten, elapsed time, and others. The best that can be done is a rough estimation of the BAC level based on known inputs. Never drive after drinking.
Disclaimer: This is in no way purported to be a guideline for how much you can drink and still drive or avoid being arrested! The best policy is don't drink and drive Period.
This calculator estimates blood alcohol concentration, but an estimate is no substitute for the actual blood alcohol test used as evidence in court.
BAC readings work alongside field sobriety tests as the two pillars of most DUI prosecutions.
