It has been been estimated that a large percentage of people driving a car on Saturday night might be driving with a blood alcohol content over the legal limit. Suppose you have had a few glasses of wine at a restaurant and then drive home. Suppose a police officer pulls you over for a traffic offense and detects an odor of alcohol. The officer might ask you to step out of the car and give you  a field coordination test. If the officer determines that you may be intoxicated, you will be taken to the precinct for further testing. Once at the precinct, the officer determines if your blood alcohol content (“BAC” for short) is over the legal limit. You will then be placed under arrest and is charged with drunk driving. How did the police determine the blood alcohol content of the driver? How can you know the result was accurate?

There are usually two ways to determine the blood alcohol content of a person. The more accurate way is to physically take out the person’s blood and send it to a lab. The more common way, however, is to give them a breath test.

This BAC calculator can only estimate your blood alcohol levels. Metabolism, body fat percentage and medication are other factors that can affect the rate of absorption by the body, and these are not considered in this calculation.

Blood alcohol content (BAC) or blood alcohol level is the concentration of alcohol in the bloodstream. It is usually measured as mass per volume. For example, a BAC of 0.04% means 0.4% (permille) or 0.04 grams of alcohol per 100 grams of individual’s blood. Use the HealthStatus BAC Calculator for informational purposes only, and not to drink and drive or drink and work.

Every state in the U.S. has a legal Blood Alchohol (BAC) limit of 0.08% per se. Most states also have lower legal BAC limits for young and inexperienced drivers, professional drivers and commercial drivers. Sentences for drunk driving include imprisonment, large fines, lengthy drivers license suspension and/or revocation, house arrest, community service, DUI schools, alcohol treatment programs, vehicle forfeiture and ignition interlock restrictions.

Important 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 (burnoff) 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.

If the police department has calculated your BAC using a breath test, the results may be challenged based upon the methods used. However, only an experienced criminal defense attorney should be consulted who is familiar with the equipment and methods used in your area.
