How much does a standard 12-ounce beer typically raise a person's BAC?

A standard 12-ounce beer typically raises a person's Blood Alcohol Concentration (BAC) by approximately 0.02%. This figure can vary depending on several factors, such as the individual's weight, sex, metabolism, and whether they have consumed food recently. However, as a general rule of thumb, consuming one standard drink (which includes a 12-ounce beer) will result in around a 0.02% increase in BAC for an average adult. Understanding this relationship is crucial for responsible drinking and is essential knowledge for anyone preparing to drive or instruct candidates on safe driving practices.
