What does BAC measure?

Explanation:
BAC measures the amount of alcohol in the blood. It reflects how much alcohol is circulating in your bloodstream at a given moment, usually expressed as a percentage or grams per deciliter. This concentration helps indicate impairment levels because higher amounts in the blood mean more effect on brain function. It’s not about how fast the body is metabolizing alcohol, nor is it simply the total amount you drank—the same amount can produce different BAC values depending on time and individual factors.
