What is the legal blood alcohol concentration (BAC) limit for riders under 21 in California?

In California, the legal blood alcohol concentration (BAC) limit for riders under 21 is 0.01%. This is part of the state's zero-tolerance policy regarding alcohol consumption by minors. The rationale behind this strict limit is to reduce the incidence of alcohol-related accidents and to promote responsible behavior among younger drivers and riders.

For individuals under 21, any measurable alcohol in their system can be grounds for being cited for DUI. This is markedly more restrictive than the general limit of 0.08% that applies to drivers aged 21 and over, clearly emphasizing the state's commitment to enhancing safety for all road users, particularly young and inexperienced riders.
