Under-21 DUI

If you are under the age of 21, you can be arrested for DUI if your Blood alcohol content is .05%, by weight. California enforces these zero-tolerance laws. Drivers under the age of 21 are subject to much stiffer penalties, including:

  • Driver License Suspension
  • Subjected to even harsher penalties if BAC is .08 or greater
  • Community Service
  • Possibility of attending AA meeting or Alcohol School

California Law For Underage DUI Cases

In San Mateo California, if you are under 21 and depending on why were pulled over, and are tested with a BAC of .01, but under .05, it is required that you stand before the DMV judge in the DMV Administrative Per Se hearing to determine if your license will be suspended. This is where an experienced DUI attorney can greatly help. He or she may be able to save your license or negotiate special circumstances enabling you to have limited driving privileges.

Please note that while over-21 drivers can refuse the field hand-held preliminary breath test, under 21 drivers, if suspected of having any alcohol, cannot refuse this test. California “zero-tolerance.” It is advised that any person 21 years, younger or older, comply with law enforcement. However also know your rights, and contact an attorney at your earliest opportunity.
