What is BAC? A Comprehensive Guide to Blood Alcohol Content

Definition & Meaning

BAC stands for blood alcohol content, which measures the amount of alcohol present in a person's bloodstream. It is commonly expressed as a percentage. For instance, a BAC of 0.08 percent indicates that there are 0.08 grams of alcohol for every 100 milliliters of blood. This measurement is crucial in assessing whether an individual is legally intoxicated, particularly in the context of driving.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A driver is pulled over for erratic driving. A breathalyzer test reveals a BAC of 0.10 percent, leading to a DUI charge.

Example 2: After a night out, an individual is stopped at a checkpoint. Their BAC is tested at 0.07 percent, which is below the legal limit, so they are not charged with DUI. (hypothetical example)

State-by-state differences

State Legal BAC Limit Notes
California 0.08% Standard limit for drivers over 21.
Texas 0.08% Similar to California, with additional penalties for higher BAC levels.
New York 0.08% Zero tolerance for drivers under 21.
