What is the legal blood alcohol concentration (BAC) limit for individuals under 21 years of age?

The legal blood alcohol concentration (BAC) limit for individuals under 21 years of age is .02. This limit is set to discourage underage drinking and to promote safer driving practices among young drivers. Since individuals in this age group are still in a developmental phase and are typically less experienced behind the wheel, the law enforces a stricter BAC limit to reduce the risk of alcohol-related accidents.

In Washington, any measurable amount of alcohol (as low as .02) can result in legal penalties for underage drivers. This approach aims to deter young people from drinking and driving and to encourage responsible behavior regarding alcohol consumption and roadway safety.
