BAC is expressed in terms of grams of alcohol per how many milliliters of blood?

  1. 50 milliliters

  2. 75 milliliters

  3. 100 milliliters

  4. 120 milliliters

The correct answer is: 100 milliliters

Blood Alcohol Concentration (BAC) is a measurement that represents the amount of alcohol present in a person's bloodstream. It is specifically quantified as grams of alcohol per 100 milliliters of blood. This unit is widely used in legal and medical contexts to determine the level of alcohol intoxication and is critical for law enforcement and other public safety officials when assessing impairment levels. Using 100 milliliters as the standard for BAC allows for consistent comparison across different individuals and scenarios, making it easier to establish legal limits, public safety regulations, and medical evaluations. This measurement standard aligns with international practices, ensuring that results are easily interpretable and universally accepted for law enforcement and health assessments.
