Under Vehicle Code §23136, what BAC limit applies to a driver under 21 years of age in California?
Explanation
Vehicle Code §23136 sets a 'zero tolerance' limit of 0.01% BAC for drivers under 21, enforced by a one-year license suspension on first offense. This is effectively any detectable alcohol — even residual mouthwash. §23140 separately makes any under-21 driver with 0.05% or higher subject to criminal penalties, and §23152 still applies at 0.08%. The under-21 driver who has 'just one beer' before driving home is committing a violation regardless of impairment.
