Yes, a DUI arrest in San Diego can put your license at risk before the criminal case is resolved. California DMV may take administrative action based on the arrest, the chemical test result, or an alleged refusal, and a separate conviction-based suspension may apply if the DUI charge leads to a conviction. The 10-day DMV hearing deadline is especially important because missing it can limit your ability to challenge the administrative suspension before it takes effect.

Our San Diego criminal lawyers provide experienced DUI license suspension defense by reviewing the arrest, challenging the DMV’s evidence when grounds exist, and guiding clients through restricted-license or reinstatement options that may help protect their driving privileges.

How Does California’s DMV Handle a DUI Arrest?
After a DUI arrest, the DMV may take action against your license in two separate ways. The first is the Administrative Per Se, or APS, process. The second is a conviction-based suspension that may apply if the DUI charge leads to a conviction in court.
APS is based on the arrest, the chemical test result, or an alleged refusal. For a first adult DUI arrest involving a completed chemical test with a BAC of 0.08% or higher, DMV can impose a 4-month suspension without waiting for a court conviction. A first refusal or failure to complete the required post-arrest chemical test can result in a 1-year suspension.
The second DMV action is conviction-based. For a first DUI conviction, DMV generally imposes a 6-month suspension. If the court refers the driver to the 9-month DUI program, such as when the BAC was 0.20% or higher, or the case involved a chemical-test refusal, the conviction-based suspension can be 10 months. When the APS and conviction-based suspensions arise from the same incident, the suspension periods may run at the same time, but the driver must still satisfy DMV requirements for reinstatement or restricted driving.
These two proceedings are separate, but both can affect the same driving privilege. A driver may win the DMV hearing and still face a conviction-based suspension after a DUI conviction. A reduction to reckless driving may help avoid the conviction-based DUI suspension, but it does not automatically undo an APS suspension from the arrest.
The table below summarizes possible suspension outcomes for a first-offense DUI:
| Suspension Type | Trigger | Suspension Length |
|---|---|---|
| Administrative Per Se (APS) | DUI arrest with a BAC of 0.08% or higher for a driver age 21 or older | 4 months |
| Conviction-Based DMV Suspension | DUI conviction | 6 months |
| First DUI conviction with 9-month DUI program referral | BAC of 0.20% or higher, chemical-test refusal, or other facts leading the court to require the longer DUI program | 10 months |
| Chemical Test Refusal | Refusal or failure to complete the required post-arrest chemical test | 1 year |
Key Takeaway: A DUI arrest can trigger an administrative DMV action before conviction, and a DUI conviction can trigger a separate DMV suspension. Each process has its own rules, deadlines, and license-defense options.
What Is the 10-Day Rule After a California DUI Arrest?
When you are arrested for a DUI in San Diego, the officer will typically take your California driver’s license and give you an Order of Suspension and Temporary License. That temporary license is usually valid for 30 days from the arrest or order date, as long as your driving privilege is otherwise valid. To protect your right to a DMV Administrative Per Se (APS) hearing before the suspension begins, the hearing request must be made within 10 days after you receive the suspension or revocation order.
If the hearing is requested on time, the DMV must hold the hearing before the suspension’s effective date. A hearing request does not automatically stay the suspension. If the DMV does not hold the hearing and make a decision before the suspension would start, the DMV must stay the suspension until it makes a decision, as long as you are otherwise eligible to drive. If no timely hearing request is made, the APS suspension can begin after the 30-day temporary license period, and you may lose the chance to fight the suspension before it takes effect.
What Happens at the DMV APS Hearing?
At the APS hearing, the issues depend on whether the case involves a completed chemical test or an alleged refusal.
In a BAC case, the DMV hearing officer reviews whether the officer had reasonable cause to believe you were driving under the influence, whether you were lawfully arrested, and whether you were driving with a BAC of 0.08% or higher. In a refusal case, the DMV also reviews whether you were told that refusing or failing to complete the required test would result in a suspension or revocation, and whether you refused or failed to complete the test.
The hearing is separate from your criminal case and focuses on whether DMV has grounds to take action against your driving privilege. An attorney can appear on your behalf, cross-examine the arresting officer, challenge the accuracy of the BAC results, and argue that required procedures were not followed. If the hearing officer determines the DMV has not met its burden on any required issue, the APS suspension will be set aside.
Key Takeaway: The safest deadline to use is 10 calendar days from receiving the DMV suspension or revocation order, which is often the arrest date. Missing this deadline can allow the APS suspension to begin after the temporary license period and can cost you the chance to challenge the suspension before it takes effect.

What Is the Administrative Per Se Suspension?
The Administrative Per Se Suspension is the DMV’s administrative action after a DUI arrest. For a first adult non-refusal case involving a completed chemical test with a BAC of 0.08% or higher, the DMV may impose a 4-month suspension without waiting for a court conviction.
If no timely hearing request is made, the APS suspension can take effect after the 30-day temporary license period. If the hearing is requested on time and DMV later upholds the suspension, the DMV will provide notice of when the suspension takes effect.
For many San Diego drivers, a license suspension can affect work, family responsibilities, treatment appointments, and daily transportation. Eligible drivers may have restricted-license options, but DMV requirements must be satisfied before a restriction is issued.
The APS suspension applies to drivers 21 and older who tested at a BAC of 0.08% or higher. Different BAC thresholds apply for other driver categories:
- Drivers under 21: BAC of 0.01% or higher
- Drivers operating a vehicle that requires a commercial driver’s license: BAC of 0.04% or higher
- Drivers on DUI probation: BAC of 0.01% or higher
What Is the IID Restricted License in California?
One option is the IID, or ignition interlock device, restriction. If DMV approves the restriction, the driver may drive anywhere in a vehicle equipped with an IID, rather than being limited to work or DUI-program travel.
If these requirements are met, the DMV may allow you to drive anywhere in a vehicle equipped with an IID. The restriction is not limited to work, school, or the DUI program. For a first-time APS non-refusal suspension, the IID restriction can last up to 4 months.
The IID is a small device installed in your vehicle’s ignition system. Before the car will start, you must blow into the device and register a BAC below a set threshold. The device also requires periodic retests while you are driving to confirm continued sobriety.
To apply for the IID restricted license, the driver must generally:
- Install an IID on any vehicle you will drive and provide DMV with the required installation proof
- Provide proof of DUI program enrollment or completion
- File an SR-22, or proof of financial responsibility, with the DMV
- Pay the applicable DMV fees, which may include APS, reissue, restriction, or administrative fees, depending on the type of action
What Is the Standard Restricted License?
If you do not want to install an ignition interlock device, the DMV may allow you to apply for an Employment/Treatment Program restriction. This restricted license allows driving to, from, and during employment and to and from the DUI program. It does not allow general driving for personal errands, school, or other purposes unless the trip fits within an authorized category.
The main tradeoff is the waiting period and driving limit. The standard restriction avoids IID installation, but it requires a 30-day hard suspension before eligibility and limits driving to employment-related travel and DUI-program travel.
Here is a side-by-side comparison of the two restricted-license options commonly available after a first-time adult APS non-refusal suspension:
| Feature | IID Restricted License | Standard Restricted License / Employment-DUI Program Restriction |
|---|---|---|
| Hard Suspension Period | No waiting period if eligible and approved | 30 days |
| Driving Restrictions | Drive anywhere in a vehicle equipped with an IID | To, from, and during employment, and to and from the DUI program |
| IID Installation Required | Yes | No |
| DUI Program Enrollment | Required | Required |
| SR-22 Filing | Required | Required |
| DMV Fees | Applicable DMV fees required | Applicable DMV fees required |

What Is the Second DUI Suspension in California?
A conviction-based DMV suspension is the second license consequence that can follow a DUI arrest. Unlike APS, this suspension depends on the criminal court outcome. If the charge is reduced to a wet reckless, dry reckless, or another non-DUI offense, the standard DUI-conviction suspension does not apply.
For a first DUI conviction, DMV generally imposes a 6-month suspension. If the court requires the longer DUI program, such as in some cases involving a BAC of 0.20% or higher or a chemical-test refusal, DMV may impose a 10-month suspension. When the APS and conviction-based suspension arise from the same incident, the suspension periods may run at the same time, but the driver must still satisfy DMV requirements for reinstatement or restricted driving.
Does a Wet Reckless Avoid the Second Suspension?
A wet reckless, dry reckless, or other non-DUI reduction can help avoid the standard DUI-conviction suspension because the conviction is not for DUI. This can be one of the most important license-related benefits of reducing a DUI charge to a lesser offense.
It does not automatically remove an APS suspension from the arrest. The driver may still need to resolve the administrative DMV action and satisfy any remaining DMV requirements. In some wet reckless cases, the court may still order an IID.
What If You Refused the Chemical Test in San Diego?
Refusing or failing to complete the required post-arrest chemical test creates a separate and harsher DMV consequence. For most adult DUI arrests, the required post-arrest test is a breath or blood test. A urine test is used only in limited situations, such as certain drug-related or medical circumstances.
Under California Vehicle Code § 13353, a first refusal after a lawful DUI arrest can trigger a 1-year license suspension. Unlike a first adult non-refusal APS suspension, a refusal suspension does not allow a restricted license during the suspension period.
The roadside PAS test should be treated separately from the required post-arrest chemical test. The refusal suspension is based on the required post-arrest chemical test, not the preliminary roadside screening test.
The consequences of refusing the post-arrest chemical test include:
- A 1-year license suspension with no restricted license available
- The refusal can be used as evidence against you in the criminal DUI case
- Enhanced penalties if convicted of the underlying DUI charge
Key Takeaway: A first post-arrest chemical-test refusal can result in a 1-year suspension with no restricted-license option during the refusal suspension period.
If DMV is treating your case as a refusal, attorney Anna R. Yum can review the arrest, the officer’s advisement, and the testing circumstances to determine whether the refusal allegation may be challenged.
What Is an SR-22 and Why Does It Matter for Your License?
An SR-22 is a certificate of financial responsibility that your auto insurance company files with the DMV on your behalf. It is not a separate type of insurance. It is a form that proves you carry at least the minimum liability coverage required by California law.
The DMV requires an SR-22 before it will reinstate your driving privilege or issue a restricted license after a DUI suspension. Without the SR-22 on file, the DMV will not approve your restricted license application, even if you have met every other requirement.
An SR-22 requirement typically lasts for three years after a DUI-related suspension. During that time, proof of financial responsibility must remain on file with the DMV. If the required proof is not maintained, the DMV can suspend the driving privilege until acceptable proof is filed again.
To file an SR-22, contact your insurance company and request that they submit the form directly to the DMV. Some insurers do not offer SR-22 filings, which means you may need to switch to a provider that does.
Can a San Diego DUI Attorney Challenge Your Suspension?
A DUI attorney can challenge the APS suspension at the DMV hearing by reviewing the evidence the DMV relies on and identifying procedural, legal, or evidentiary issues. Common grounds for challenge may include:
- The traffic stop lacked reasonable cause
- The arrest was not conducted lawfully
- The breath or blood test was improperly administered or the results were inaccurate
- The officer did not follow the required procedures, such as the 15-minute observation period before a breath test
- The BAC results do not reliably reflect your BAC at the time of driving
If the hearing officer finds that the DMV has not met its burden on any of the required elements, the APS suspension will be set aside and your license will not be suspended through the administrative process.
Even if the APS suspension is upheld, the hearing provides an opportunity to obtain sworn testimony from the arresting officer. This testimony is recorded and can be used in your criminal DUI case, giving your defense attorney valuable information that may not otherwise be available at that stage of the proceedings.
Requesting the DMV hearing can be an important step because it preserves the opportunity to challenge the APS action before the suspension takes effect. The 10-day deadline to request the hearing makes it important to contact an attorney as soon as possible after a DUI arrest in San Diego.

Frequently Asked Questions About DUI License Suspension
How long will my license be suspended for a first DUI in California?
A first adult non-refusal DUI arrest can result in a 4-month APS suspension if the chemical test shows a BAC of 0.08% or higher. A first DUI conviction generally triggers a 6-month conviction-based suspension, or 10 months if the court requires the longer DUI program. A first refusal can result in a 1-year suspension with no restricted-license option during the refusal suspension period.
Can I drive at all after a DUI arrest in San Diego?
Yes, in many cases. The Order of Suspension and Temporary License usually allows driving for 30 days if the driver’s privilege is otherwise valid. A timely DMV hearing request protects the right to challenge the APS action before the suspension begins. If APS is imposed, eligible first-time non-refusal drivers may be able to apply for an IID or standard restricted license.
What is the difference between the IID option and the standard restricted license?
The IID option requires installation of an ignition interlock device but allows driving anywhere in an IID-equipped vehicle if all DMV requirements are met. The standard restriction avoids IID installation but limits driving to employment-related travel and DUI-program travel, and it requires a 30-day hard suspension before eligibility.
What happens if I miss the 10-day DMV hearing request deadline?
If you do not request a DMV APS hearing within 10 calendar days after receiving the suspension or revocation order, the APS suspension can begin after the temporary license period. Missing the deadline can also cost you the chance to challenge the administrative suspension before it takes effect.
Will my license be suspended before I’m convicted?
Yes. APS is an administrative DMV action that can apply before any criminal conviction if DMV has grounds to act based on the arrest, the chemical test result, or an alleged refusal.
Does a DUI conviction always trigger a second suspension?
A DUI conviction can trigger a conviction-based DMV suspension. If the charge is reduced to a wet reckless, dry reckless, or another non-DUI offense, the standard DUI-conviction suspension does not apply. The reduction does not automatically erase an APS suspension from the arrest.
Can I get a restricted license if I refused the post-arrest chemical test?
No. Refusing or failing to complete the required post-arrest chemical test can result in a 1-year suspension for a first offense, with no restricted license during that suspension. This is separate from the preliminary roadside screening test.
How does a DUI suspension affect my SR-22 insurance requirement?
DMV requires an SR-22 before it will issue a restricted license or reinstate full driving privileges after a DUI-related suspension. The SR-22 must remain on file for three years. If the filing lapses, DMV can suspend the license again.
