What is the BAC threshold for DUI offenses in California for individuals under the age of 21?

In California, the legal Blood Alcohol Concentration (BAC) threshold for individuals under the age of 21 is 0.00%. This is part of a zero-tolerance policy aimed at reducing underage drinking and driving. Under this law, any measurable amount of alcohol in the bloodstream for drivers under 21 can result in a DUI charge. This strict standard reflects the state's commitment to preventing alcohol-related accidents among young drivers and emphasizes a proactive approach to public safety. The other options represent BAC thresholds applicable to different categories of drivers or circumstances, but they do not apply to underage individuals, making the zero-tolerance threshold the appropriate standard.
