California Zero Tolerance Laws

California's Zero Tolerance Law states the following:

  • It is illegal for an underage youth to drive with a blood alcohol content (BAC) above 0.01%. For most to reach a BAC of 0.01% that means drinking either one 12 once beer, once 4 ounce glass of wine or one drink with 1.25 ounces of 80 proof distilled spirits.
  • If a youth is suspected of drinking by a police officer, the officer may require a Preliminary Alcohol Screening Test or other chemical tests.
  • A youth that refuses to submit or fails to take the test, or is found to have a BAC equal to or above 0.01%, can have their driver's license suspended for up to 1-3 years.
