In California, an underage DUI can derail a young person’s future in an instant. With the state’s strict zero-tolerance policy, even minimal alcohol consumption can trigger severe penalties for drivers under 21. If you or your child is facing an underage DUI charge in Los Angeles, you have only 10 days to request a DMV hearing to prevent automatic license suspension. The dual-track legal process—involving both criminal court and DMV proceedings—requires immediate, experienced legal representation to protect your rights and future opportunities.
What Is an Under 21 DUI in California?
California enforces a strict zero-tolerance policy for drivers under 21 through Vehicle Code 23136. Unlike standard DUI laws that apply to adults, underage drivers face penalties for having any measurable amount of alcohol in their system—as little as 0.01% blood alcohol concentration (BAC). This means even a single sip of alcohol can lead to serious consequences.
Under 21 DUI cases in Los Angeles typically fall into three categories:
- Zero Tolerance (VC 23136): BAC of 0.01% or higher, resulting in administrative penalties
- Underage DUI (VC 23140): BAC of 0.05% to 0.07%, resulting in infraction charges
- Standard DUI (VC 23152): BAC of 0.08% or higher, resulting in misdemeanor charges
What makes these cases particularly challenging is that they operate as “per se” violations—meaning the prosecution doesn’t need to prove actual impairment, only that alcohol was present in the underage driver’s system while operating a vehicle.
The Dual-Process System: Criminal Court and DMV Hearings
An under 21 DUI in Los Angeles triggers two separate legal processes that run concurrently:
Criminal Court Process
Depending on the BAC level, the underage driver may face:
- Infraction charges (BAC 0.05%-0.07%)
- Misdemeanor charges (BAC 0.08% or higher)
- Court appearances
- Potential fines and penalties
- Mandatory alcohol education programs
DMV Administrative Process
Regardless of criminal charges, the DMV process includes:
- Automatic license suspension unless contested
- 10-day deadline to request a hearing
- Administrative Per Se (APS) hearing
- Potential one-year license suspension
- Restricted license possibilities
The 10-day deadline to request a DMV hearing is critical. Missing this deadline results in automatic license suspension, regardless of the outcome of any criminal case. This makes immediate legal representation essential for protecting driving privileges.

Potential Penalties and Consequences for Under 21 DUI
The consequences of an underage DUI in Los Angeles extend far beyond the immediate legal penalties. Young drivers face both short-term and long-term impacts that can affect their education, career, and personal life.
Administrative Penalties (Zero Tolerance – VC 23136)
- One-year driver’s license suspension
- No possibility of a restricted license during suspension
- Mandatory completion of alcohol education program
- $100 fine plus penalty assessments
Criminal Penalties (BAC 0.05%-0.07% – VC 23140)
- Infraction on criminal record
- $100 fine plus penalty assessments
- One-year driver’s license suspension
- Mandatory alcohol education program (3+ months)
Criminal Penalties (BAC 0.08% or higher – VC 23152)
- Misdemeanor on criminal record
- Up to 6 months in county jail
- Fines between $390-$1,000 plus penalty assessments
- 3-5 years of informal probation
- 9-month alcohol education program
- One-year driver’s license suspension
Long-Term Consequences
- Significantly increased auto insurance rates (often 100-300% higher)
- College application and scholarship impacts
- Employment difficulties, especially for jobs requiring driving
- Professional license restrictions
- Housing application challenges
- Immigration consequences for non-citizens
The severity of these consequences makes it essential to secure experienced legal representation immediately after an underage DUI arrest in Los Angeles. A skilled attorney can challenge evidence, negotiate reduced charges, and work to minimize the impact on your future.
The DMV Administrative Per Se (APS) Hearing Process

The DMV hearing is entirely separate from any criminal court proceedings and focuses solely on the administrative suspension of driving privileges. For underage drivers, this hearing is particularly critical.
What Happens at a DMV Hearing?
During an Administrative Per Se hearing for an under 21 DUI, the DMV hearing officer will consider only three factors:
- Was the driver under 21 at the time of the arrest?
- Was the driver operating a vehicle with a BAC of 0.01% or higher?
- Was the preliminary alcohol screening (PAS) test administered lawfully?
Unlike criminal court, the standard of proof at DMV hearings is lower—only a “preponderance of evidence” rather than “beyond reasonable doubt.” This makes challenging the suspension more difficult without experienced legal representation.
How to Request a DMV Hearing
You must contact the DMV within 10 calendar days of the arrest to request an APS hearing. This request must be made to the Driver Safety Office that serves your area. Failure to request this hearing within the deadline results in automatic license suspension.
Potential Outcomes of DMV Hearings
- Set Aside: The suspension is canceled, and driving privileges remain intact
- Sustained: The one-year suspension is upheld
- Modified: In some cases, a restricted license may be granted for school or work
A skilled DUI defense attorney can represent you at this hearing, challenge the evidence, cross-examine the arresting officer, and present arguments against suspension. This representation significantly improves your chances of a favorable outcome.

Effective Legal Defenses for Under 21 DUI Cases
Despite California’s strict zero-tolerance policy, there are several effective legal defenses that can be employed in underage DUI cases. A skilled attorney can evaluate your specific situation and determine the most appropriate strategies.
Common Defenses in Under 21 DUI Cases
- Challenging the Traffic Stop: If the officer lacked reasonable suspicion to initiate the traffic stop, all evidence obtained afterward may be suppressed.
- Testing Equipment Inaccuracies: Breathalyzers and PAS devices require proper calibration and maintenance. Records showing improper calibration can invalidate test results.
- Rising Blood Alcohol: Your BAC may have been below the legal limit while driving but rose to an illegal level by the time of testing.
- Mouth Alcohol Contamination: Recent use of mouthwash, breath fresheners, or certain medications can cause falsely elevated breath test readings.
- Medical Conditions: Certain medical conditions like GERD, acid reflux, or diabetes can affect breath test accuracy.
- Improper Testing Procedures: Officers must follow specific protocols when administering chemical tests. Deviations from these procedures can invalidate results.
- Lack of Actual Driving: The prosecution must prove you were actually driving the vehicle, not merely sitting in it.
DMV Hearing Defenses
At the DMV hearing, additional defenses may include:
- Challenging the officer’s observations and reports
- Questioning the chain of custody for blood samples
- Arguing procedural violations in the administration of tests
- Presenting evidence of testing equipment malfunction
Each case is unique, and the appropriate defense strategy depends on the specific circumstances of your arrest. An experienced DUI defense attorney can identify the strongest defenses in your case and implement them effectively in both criminal court and DMV proceedings.

Frequently Asked Questions About Under 21 DUI in Los Angeles
Can you get a DUI under 21 in California with a low BAC?
Yes. California’s zero-tolerance law (Vehicle Code 23136) makes it illegal for anyone under 21 to drive with any measurable amount of alcohol in their system—as low as 0.01% BAC. This is significantly lower than the 0.08% threshold for drivers 21 and older. Even a single drink can put an underage driver over this limit.
What is the zero-tolerance policy for drivers under 21 in California?
California’s zero-tolerance policy means that drivers under 21 cannot have any measurable alcohol in their system while driving. This policy is enforced through Vehicle Code 23136, which makes it unlawful for underage drivers to operate a vehicle with a BAC of 0.01% or higher. The policy exists to deter underage drinking and driving and is enforced through administrative penalties, primarily license suspension.
What happens to your license after an underage DUI in Los Angeles?
An underage DUI typically results in a one-year suspension of driving privileges. This suspension is automatic unless you request a DMV hearing within 10 days of the arrest and successfully challenge the suspension. For BAC levels of 0.01% to 0.04%, the suspension is purely administrative. For higher BAC levels, additional court-ordered suspensions may apply. In some cases, restricted licenses for school or work may be available after a portion of the suspension period.
Do underage DUI cases involve criminal charges?
It depends on the BAC level. For BAC of 0.01% to 0.04%, the violation is administrative only (not criminal). For BAC of 0.05% to 0.07%, it’s an infraction under Vehicle Code 23140. For BAC of 0.08% or higher, underage drivers face the same misdemeanor criminal charges as adults under Vehicle Code 23152. Each level carries progressively more severe penalties, with the highest BAC levels potentially resulting in jail time, probation, and significant fines.
Why is it important to contact a lawyer immediately after an underage DUI arrest?
Immediate legal representation is critical because you have only 10 days from the arrest date to request a DMV hearing to prevent automatic license suspension. Additionally, early intervention allows an attorney to gather fresh evidence, interview witnesses while memories are clear, and develop the strongest possible defense strategy. Early representation can also lead to better negotiation positions with prosecutors and potentially reduced charges or penalties.
