It is a common misconception that drinking only one beer per hour will keep an individual within the legal limit to avoid a DUI. Regardless of what online blood alcohol concentration (BAC)
calculators tell you, they cannot honestly predict how a person’s body will react to one beer or glass or wine, thus incorrectly predicting their blood alcohol concentration and putting them at risk for DUI charges.
BAC calculator or “drink wheel”
There are several sites online where a person can enter their gender, height, weight, and drinks consumed resulting in a predicted blood alcohol concentration percentage. Unfortunately, many people trust these calculators and are surprised when they still end up with a DUI.
Other factors to include
Beyond gender, height, weight, and number/types of drinks consumed, there are several other aspects that can play a part in affecting blood alcohol concentration. These include:
• With or without food. When someone drinks on an empty stomach they usually feel drunk right away. This is because there is nothing in the stomach to slow the absorption of alcohol so it isimmediately absorbed into the stomach lining. Drinking with a full stomach results in a slower absorption of alcohol, causing a person to feel the effects of drinking gradually. By slowing down the absorption rate however, BAC levels are also decreased slower, remaining elevated longer than expected.
• Fat or muscle. When entering a person’s weight in a BAC calculator, it should also include body fat percentage. Someone who has higher muscle content will be able to absorb the alcohol swifter than someone with high body fat due to the lack of water in the fat cells. Thus, someone with high body fat may be more likely to get a DUI if they trust a BAC calculator to determine their BAC levels.
• Alcohol metabolism rate. According to the U.S. Department of Health, alcohol metabolism is “the way in which alcohol is broken down and eliminated by the body.” Everyone is different and we all metabolize alcohol at different rates depending on our level of enzymes that break down alcohol. BAC calculators work on averages only and shouldn’t be trusted to know everyone’s exact rate of metabolizing alcohol.
Don’t chance a DUI
Due all the different factors that could affect the way alcohol is metabolized in the body, it is recommended to not take chances of incurring DUI charges by trusting anything other than a breathalyzer. If you drink-phone a friend, call a cab, or sleep it off. If you are already facing DUI charges, contact a criminal defense attorney immediately.
