California DMV Permit Test (Class C)Alcohol and DrugsEasy

A 21-year-old driver is stopped by law enforcement and found to have a blood alcohol concentration (BAC) of 0.03%. What is the most likely legal consequence?

  1. AA warning, with no further action taken.
  2. BA DUI arrest and license suspension under California's 'Zero Tolerance' law.
  3. CA citation for an open container violation, but no DUI.
  4. DNo legal consequence, as the BAC is below the 0.08% legal limit for adults.
Show answer & explanation

Correct answer: B. A DUI arrest and license suspension under California's 'Zero Tolerance' law.

California's 'Zero Tolerance' law applies to drivers under 21, making it illegal to drive with any measurable amount of alcohol, specifically a BAC of 0.01% or higher. A BAC of 0.03% falls within this prohibited range, leading to a DUI arrest and license suspension.

Why the other options are wrong

  • A. This is incorrect; a BAC of 0.03% is above the legal limit for drivers under 21, triggering legal action.
  • C. This is incorrect; while an open container might be a separate offense, the BAC itself triggers a DUI under zero tolerance.
  • D. This statement is incorrect; the 0.08% limit applies to drivers 21 and over, not those under 21.

Zero Tolerance Law (CA)

In California, it is illegal for drivers under 21 to drive with a blood alcohol concentration (BAC) of 0.01% or higher.

  • Applies to drivers under 21.
  • BAC of 0.01% or higher is illegal.
  • Consequences include license suspension and DUI charges.

Memory trick: Young drivers, zero alcohol, zero tolerance.
