Blood alcohol concentration (BAC) is the amount of alcohol in a person’s bloodstream. It is typically measured as a percentage, with a BAC of 0.08% meaning that there are 0.08 grams of alcohol per 100 milliliters of blood.
A high BAC can lead to a number of dangerous consequences, including impaired judgment, coordination, and reaction time. It can also increase the risk of accidents, injuries, and death.
