California Zero Tolerance DUI Defense for Minors

What Is California’s Zero Tolerance Law for Underage DUI?

California enforces a strict Zero Tolerance Law for drivers under 21, meaning any detectable amount of alcohol in their system can lead to serious consequences. Under California Vehicle Code § 23136, anyone under 21 with a Blood Alcohol Content (BAC) of 0.01% or higher while driving can face administrative penalties. This law applies even if a driver’s BAC is well below the legal limit for adults, aiming to deter young drivers from drinking and driving entirely.

The consequences of violating this law underscore California’s firm stance on underage DUI. Even a BAC of 0.01%—less than the equivalent of a single drink—can result in a one-year license suspension, making transportation to work, school, and other essential activities much more challenging. California’s zero-tolerance approach is designed to prevent young drivers from the dangerous decision of driving under the influence, given the significant impact a DUI conviction can have on a young person’s future.


Legal BAC Limits for Underage Drivers in California

0.01% BAC or Higher: Violating the Zero Tolerance Law results in an administrative license suspension for up to one year. This applies regardless of driving ability, reflecting California’s uncompromising stance on alcohol consumption by underage drivers.

0.05% BAC or Higher: At this level, a driver may be charged with an Underage DUI under California Vehicle Code § 23140. This can involve penalties beyond a suspension, such as fines, mandatory DUI education programs, and possible community service.

0.08% BAC or Higher: If an underage driver’s BAC reaches the standard adult limit, they can be charged with a standard DUI, facing the same serious penalties as those over 21. This includes potential jail time, larger fines, and an extended license suspension.


Penalties for an Underage DUI in California

For a Zero Tolerance Violation (0.01% BAC or higher), a driver under 21 faces a mandatory one-year license suspension, which applies even for minimal alcohol levels.

If the BAC is 0.05% or Higher, the penalties increase to include fines, participation in a DUI education program, and possible community service, according to California Vehicle Code § 23140.

For 0.08% or Higher, young drivers are subject to the same penalties as adult offenders, including more significant fines, a longer license suspension, mandatory DUI school, and in some cases, jail time.

The penalties for underage DUIs are harsh, especially for repeat offenders. Young drivers risk longer license suspensions and, in severe cases, may even face felony charges. This structured approach is intended to deter risky behavior by young drivers, underlining California’s firm stance on driving under the influence at any age.


Can You Be Charged with a DUI Under 21 Without Alcohol?

Yes, California’s DUI laws extend beyond alcohol—drivers under 21 can face DUI charges for operating a vehicle under the influence of drugs, including marijuana. Under the zero-tolerance policy, any controlled substance that impairs driving is grounds for a DUI charge. This includes prescription medications if they affect the driver’s ability to operate a vehicle safely.

For example, a young driver who uses marijuana legally but shows signs of impaired driving can still be charged with a DUI. The law’s scope reflects California’s commitment to road safety, applying the same standards to drugs as it does to alcohol. This means that underage drivers should be fully aware of how any substance, including legal ones, could lead to a DUI charge if it compromises their ability to drive safely.


Refusing a Breathalyzer Test Under 21: What Are the Consequences?

For drivers under 21 in California, refusing to take a preliminary alcohol screening (PAS) or a chemical test during a DUI stop carries significant consequences. California’s implied consent law mandates that any driver lawfully detained under suspicion of DUI must submit to a breathalyzer or PAS test. If an underage driver refuses, they face an automatic one-year license suspension, regardless of their actual blood alcohol content (BAC).

This refusal can also lead to additional penalties, such as fines and extended suspension periods, often exceeding the consequences of taking and failing the test. The penalties are intentionally severe to discourage refusal and maintain road safety, especially for young drivers who fall under California’s zero-tolerance policies. Facing these consequences alone can be overwhelming, making legal representation essential to navigate the charges and potentially reduce the penalties associated with a refusal.


Can You Avoid a License Suspension for an Underage DUI?

While an underage DUI typically triggers an automatic license suspension, there are legal options and defense strategies to contest or reduce this outcome. One of the most crucial steps is to request a DMV Administrative Per Se (APS) hearing within 10 days of the arrest. This hearing provides an opportunity to challenge the suspension and present evidence supporting the driver’s case.

A skilled DUI attorney can advocate on behalf of young drivers by examining the legality of the traffic stop, scrutinizing the procedures used for BAC testing, and questioning the reliability of the results. If any procedural errors or inconsistencies are found, these can be used to strengthen the defense and increase the likelihood of avoiding a suspension. Effective legal support can make a substantial difference in preserving driving privileges and minimizing the impact of an underage DUI on a young person’s future.


How the DMV Handles Underage DUIs in California

The California DMV enforces strict administrative penalties for underage drivers with any detectable blood alcohol content. These penalties are separate from criminal court actions and focus primarily on license suspensions and revocations, aiming to deter young drivers from drinking and driving.

  • First Offense (0.01% BAC or Higher): A first-time underage DUI offense at any BAC above zero results in a one-year license suspension. This administrative action occurs regardless of any court-imposed penalties.
  • Second Offense Within 10 Years: A second underage DUI offense within a 10-year period results in a two-year license revocation, significantly limiting driving privileges for an extended time.
  • Third Offense Within 10 Years: A third underage DUI offense within a decade leads to a three-year license revocation.

Underage drivers with a suspended or revoked license generally do not qualify for a restricted license unless they meet specific criteria for a hardship license, such as a demonstrated necessity for work or school.


How the Criminal Court Handles DUIs for Drivers Under 21

In California, criminal courts handle underage DUI cases with a clear focus on both penalizing and educating young drivers. When a driver under 21 has a BAC of 0.08% or higher, they face the same penalties as adult drivers, which may include jail time, probation, significant fines, a suspended license, and mandatory DUI education programs. This standard DUI charge applies regardless of age if the BAC reaches the adult threshold, often carrying severe consequences.

For underage drivers with a BAC of 0.05% to 0.07%, a different level of charge applies under Vehicle Code § 23140. This is treated as a misdemeanor offense, generally without jail time, but it still imposes fines and mandatory DUI education programs aimed at discouraging future violations. Importantly, these criminal court penalties are separate from DMV administrative actions and add additional layers of consequence, potentially including a criminal record that could impact future employment, education, and housing opportunities. The dual impact of DMV and court penalties makes it essential for underage drivers facing DUI charges to have a knowledgeable DUI attorney advocating on their behalf.


How Our DUI Lawyer Can Help Fight Underage DUI Charges

Challenging Probable Cause: For any DUI stop to be legal, law enforcement must have reasonable suspicion. If the officer did not have sufficient cause to initiate the stop, we can argue for dismissal, challenging the foundation of the case from the start.

Questioning Test Accuracy: Breathalyzer and preliminary alcohol screening (PAS) devices must be calibrated and administered correctly. Our team carefully examines testing protocols and device maintenance records to identify any inconsistencies. If procedures were not properly followed, we can challenge the reliability of test results, weakening the prosecution’s case.

Plea Bargaining for Lesser Charges: For clients with higher BAC levels, Attorney Hashemi works to negotiate lesser charges, such as a “wet reckless,” which carries fewer penalties than a standard DUI. Reducing the charge can minimize the impact on the young driver’s record and future.

Protecting Driving Privileges: License suspensions have a substantial effect on mobility and daily life, especially for young drivers. We represent clients at DMV hearings, fighting to contest suspensions or negotiate for restricted licenses that allow necessary driving for school or work.

Our goal is to provide underage clients with a comprehensive defense that minimizes penalties and protects their future. If your child is facing an underage DUI, we are here to guide you through each step and work tirelessly to secure the best possible outcome.
