After a DUI arrest in San Diego, the California Department of Motor Vehicles (DMV) begins a separate administrative process that can suspend or revoke your driver’s license. This process is completely independent of any criminal case you face in court. You generally have 10 days from the date of your arrest to request a DMV hearing. If you do not request a hearing on time, the APS action usually takes effect after the 30-day temporary license period ends.
The good news is that you have options. If you request the hearing on time and DMV cannot hold it before the action’s effective date, the APS action is stayed while the hearing is pending. You can challenge the legality of the traffic stop, question whether the arresting officer followed proper chemical testing procedures, and dispute the accuracy of breath or blood test results. If the DMV cannot prove the legal basis for the APS action, it may set the suspension or revocation aside.

What Happens After a DUI Arrest and Before Your San Diego DMV Hearing?
When a law enforcement officer arrests you for DUI, they will typically confiscate your California driver’s license on the spot. In exchange, you will receive a pink form called a DS 367 (Notice of Suspension). This document serves as your temporary driving permit for 30 days, but only if your license was valid at the time of the arrest. If your license was already suspended or revoked before the DUI stop, the DS 367 does not authorize you to drive.
The notice also tells you about the 10-day window to request a DMV hearing. Requesting the hearing can delay the APS action and lets you contest it at a formal hearing. DMV hearings are handled through its Driver Safety offices, and the Driver Safety Portal can be used to request and schedule a hearing.
If you do not request the hearing within 10 days, the APS action generally goes into effect after the 30-day temporary license period ends. That means you lose the opportunity to challenge the APS action before it takes effect.
Key Takeaway: Timely requesting a San Diego DMV hearing after a DUI is crucial to protect your driving privileges and challenge the APS suspension effectively.
How Is a San Diego DMV Hearing Different from Criminal Court?
Many people do not realize that a DUI arrest triggers two entirely separate legal processes. One plays out at the San Diego Superior Court, where a judge decides questions of guilt, fines, and possible jail time. The other plays out before a DMV hearing officer, who decides only whether your driving privileges should be suspended.
These two proceedings operate under different rules and standards. The criminal court focuses on whether you committed a crime. The DMV hearing focuses solely on the administrative consequences for your license. This distinction matters because you can win your criminal case and still lose your license at the DMV, or you can prevail at the DMV while still facing criminal penalties in court.
The standard of proof also differs in important ways. In criminal court, the prosecution must prove guilt beyond a reasonable doubt. At a DMV hearing, the burden is lower: the DMV must prove its case only by a preponderance of the evidence, meaning it is more likely than not that you violated the law. You do not have to establish your innocence beyond a reasonable doubt; you only need to raise enough doubt to tip the scales in your favor.
What Must the DMV Prove at a California DUI Hearing?
The DMV bears the burden of proof at a standard DUI hearing. It must establish its case by a preponderance of the evidence, relying on materials such as the arresting officer’s police report, witness statements, and chemical test results.
In a California Administrative Per Se (APS) hearing, the issues the DMV considers depend on the type of case.
If you took a chemical test, the hearing officer typically examines whether:
- The officer had reasonable cause to believe you were driving under the influence
- You were lawfully arrested
- Your blood alcohol concentration (BAC) was 0.08% or higher while driving
If the DMV claims you refused a chemical test, the hearing officer instead examines whether:
- The officer had reasonable cause to believe you were driving under the influence
- You were lawfully arrested
- You were properly advised that refusing the test could lead to a license suspension or revocation
- You actually refused or failed to complete the test
If the DMV cannot prove the required issues for the type of case involved, the hearing officer may set the APS action aside.

What Are Your Rights at a San Diego DMV Hearing?
California law gives you several important rights during the DMV hearing process. Careful consideration of these rights helps you prepare a more effective defense and avoid waiving protections you are entitled to use.
The Right to Legal Representation
You may represent yourself at a DMV hearing, but unlike in a criminal proceeding, the DMV does not provide a public defender. If you want an attorney, you must retain one at your own expense. An attorney who regularly handles DUI cases locally knows the hearing officers, understands which procedural challenges carry the most weight, and can cross-examine evidence in ways that non-attorneys typically cannot.
The Right to Review and Challenge Evidence
Before the hearing, and upon request, you and your attorney may review and obtain copies of the DMV’s evidence. That commonly includes the officer’s sworn report and supporting documents, such as chemical-test records. Your legal team may challenge that evidence at the hearing.
The Right to Present Your Own Case
Your legal team may introduce your own supporting documentation, call witnesses on your behalf, and submit alternative explanations for the evidence. For example, you might present medical records showing a condition that affects breathalyzer readings, or obtain testimony from a passenger who observed your behavior before and during the stop.
The Right to Cross-Examine
If the DMV presents witnesses, your attorney can cross-examine them.
Key Takeaway: California law gives you meaningful participation rights at a DMV hearing, including the right to review evidence, present witnesses, and cross-examine the DMV’s witnesses.

What Defenses Can You Raise at a California DMV Hearing?
Depending on the circumstances of your case, your attorney can raise the following defenses:
The Traffic Stop Was Unlawful
For a traffic stop to be legally valid, the officer must have had reasonable suspicion that you were violating the law. Swerving, speeding, a broken taillight, or observable signs of impairment can all justify a stop. However, if none of those conditions existed, you may argue that the officer lacked reasonable suspicion to justify the traffic stop. An unlawful stop can lead to the suppression of all evidence gathered afterward, including breathalyzer results and officer observations, effectively eliminating the DMV’s case.
You Were Not Impaired
If you maintain that you were not under the influence at the time of the stop, you can challenge the prosecution’s primary claim directly. Field sobriety test results, while commonly used, are not conclusive. They can be challenged based on conditions like uneven pavement, poor lighting, or the driver’s physical health. Witness testimony from passengers or bystanders who observed your conduct before and during the stop can also support this defense.
The Chemical Test Was Administered Improperly
California’s Title 17 of the Code of Regulations sets out detailed requirements for administering DUI chemical tests. These rules cover:
- Use of trained and certified technicians
- Proper calibration and maintenance of testing equipment
- A continuous 15-minute observation period before administering a breath test
- A documented chain of custody for blood samples
If the arresting officer or testing technician failed to follow any of these procedures, the test results may be inadmissible. Review the police report carefully for gaps in the observation period, calibration logs, or chain-of-custody documentation. A Title 17 violation does not automatically mean dismissal, but it can significantly undermine the DMV’s case and may result in reduced or eliminated penalties.
A Medical Condition Mimicked Intoxication
Certain medical conditions, including diabetes, inner ear disorders, acid reflux, and some prescription medications, can produce symptoms that resemble intoxication or artificially elevate breathalyzer readings. To raise this defense successfully, you typically need documentation from a licensed physician and medical records that connect your specific condition to the symptoms observed during the stop. Witness testimony about your behavior at the time of the encounter can also be helpful.
You Were Not the Driver
In some cases, the identity of the driver is genuinely in dispute. Eyewitness statements, security footage, receipts placing you elsewhere, or documentation showing someone else had access to the vehicle can all support a “not the driver” defense. This argument challenges the first element the DMV must establish, and if it succeeds, the entire basis for suspension is removed.
Key Takeaway: Effective defenses at a California DMV hearing range from challenging the lawfulness of the traffic stop to disputing chemical test procedures under Title 17. A strong defense on any single element can result in the suspension being set aside entirely.
What Are the Possible Outcomes and DUI Penalties?
The outcome of your hearing will usually be either favorable or adverse. A favorable result means the DMV sets aside the APS action, so the suspension or revocation does not go into effect on that basis. An adverse result means the APS suspension or revocation is sustained. Requests for a restricted license are handled separately and are not decided at the hearing itself.
An adverse result typically means a license suspension. California imposes different suspension lengths depending on the nature of the offense and your prior driving history.
| Offense Type | BAC Level | Suspension or Revocation |
|---|---|---|
| First DUI (standard) | 0.08% or higher | 4 months |
| Second or subsequent DUI | 0.08% or higher | 1 year minimum |
| Underage DUI | 0.01% or higher | 1 year minimum per offense |
| Chemical test refusal, first offense | Any | 1-year suspension |
| Chemical test refusal, second offense | Any | 2-year revocation |
| Chemical test refusal, third offense | Any | 3-year revocation |
In some cases, you may be eligible for a restricted license. For some first-offender APS cases, the DMV allows an ignition interlock device (IID) restricted license immediately. In other cases, a work-and-DUI-program restriction is available only after a 30-day suspension period. The exact option depends on the type of offense and your eligibility.
Reinstatement requirements depend on the type of suspension and whether any court-ordered consequences also apply. For an APS suspension or revocation, drivers generally must file proof of financial responsibility and pay the required reissue fee. In some cases, a DUI program is also required for a restriction or because of a separate court-based suspension.
How Can You Appeal a DMV Hearing Decision?
If you disagree with the hearing officer’s ruling, two appeal paths are available under California law. Each option carries different requirements, costs, and levels of formality.
The first option is a departmental review, which asks the DMV to review the hearing decision. The California DMV allows you to request a departmental review within 15 days of the effective date of the decision notice, and the fee is $120.
The second option is court review. Apart from the departmental review process, you may request court review within 30 days following the issuance of the notice of the hearing decision.
