Under-21 DUI in Pleasanton

Drivers under the age of 21 are not supposed to have legal access to alcohol in California. Under California's Zero Tolerance policy, an under-21 driver with any amount of alcohol in the body (testing above 0.01% by blood alcohol concentration (BAC) is in violation of the law. 

Under 21 drivers are also subject to more restrictive breath testing policies. While most drivers have the right to refuse to submit to a roadside breath test, drivers who are under 21 and suspected of being impaired by alcohol have to take the breath test. 

The roadside breath testing device is known as a preliminary alcohol screening (PAS) device. This is a handheld breath testing device that gives an estimate of the driver's BAC. However, these devices are not always reliable and can be triggered by false positives. This is one of the reasons why these tests are not mandatory for most drivers. Unfortunately, drivers under 21 and drivers on probation for a DUI cannot refuse these PAS tests. Refusing a breath test for a driver under 21 will result in a one-year license suspension. 

Penalties for an Underage DUI in Pleasanton 

The penalties for an under-21 DUI will depend on the specific offense, the driver's BAC, and other relevant factors. 

Zero Tolerance Violation (0.01% to less than 0.05%)

A zero-tolerance violation where the driver's BAC is under 0.01% generally results in a 1-year license suspension. 

Under 21 DUI (0.05% to less than 0.08%)

Under California Vehicle Code 23140, it is unlawful for a person under the age of 21 to have a BAC of 0.05% or to be found to be under the influence or affected by alcohol. The penalties for an underage DUI include a one-year license suspension, a fine, and alcohol education course.

Per Se DUI (0.08% or higher)

Any driver, regardless of age, can face a per se DUI with a BAC of 0.08% or higher. The penalties for a first-offense DUI include:

  • 6-month license suspension,
  • Probation,
  • Fine,
  • DUI school, and
  • Up to 6 months in jail.

Aggravating factors can increase the penalties for a driver, including having a high BAC (0.15% or higher), a DUI accident, or having a minor in the vehicle under the age of 14 at the time. 

Don't Lose Your License 

You only have 10 days after a DUI arrest to request a hearing to keep your license. This comes as a surprise for most people facing a first-time DUI. The license suspension process is separate from the criminal process. During an arrest, the police will generally take your license and issue a temporary driving permit. This temporary license is only good for 30 days. 

However, you only have 10 days after the arrest to request a hearing with the California Department of Motor Vehicles (DMV) to challenge the suspension. Talk to your California DUI lawyer about requesting a hearing and make sure your lawyer can challenge the license suspension so you can keep your driving privileges. 

Other Consequences of a DUI for Young Drivers

Young drivers have additional consequences that may follow a DUI conviction. A DUI will go on your criminal record as well as your driving record. This can make it hard to get auto insurance and insurance rates may be much higher after a DUI. College and grad school applications may also ask about convictions, which could impact your chances at getting into a competitive program or getting scholarship money.
