Blood alcohol concentration (BAC) is the amount of alcohol in a person’s bloodstream, expressed as a percentage (for example, 0.08% means 0.08 grams of alcohol per 100 milliliters of blood). It’s the standard measure used to determine impairment from alcohol.
Legal BAC for teen drivers:
- In many jurisdictions (including most U.S. states) there is a “zero‑tolerance” rule for drivers under 21, meaning any detectable alcohol can lead to penalties. Practically this is usually set at 0.02% BAC (to allow for tiny residual amounts from mouthwash/medication) or 0.00% in some places.
- Because laws vary by state/country, check the specific law where you live for the exact limit and related penalties.
