The 10-Day Clock: Understanding California's Admin Per Se (APS) Process After a DUI Arrest
If you've been arrested for DUI in California, you're facing two separate legal battles at the same time — and most people only know about one of them. The criminal case in court is the one everyone expects. The other, quieter one is already running against your driver's license, on a clock that starts the day you're arrested and expires in just ten days. That process is called Administrative Per Se, or APS, and understanding it is the difference between keeping your license and losing it before you've even seen a courtroom.
This guide explains what the APS process is, how the DMV suspension works, what happens at the hearing, and — most importantly — the deadline you cannot afford to miss.
Two Cases, Not One: The DMV Is Separate From Court
The single most important thing to understand about a California DUI is that your arrest triggers two completely independent proceedings:
The criminal case is prosecuted by the District Attorney in court. It decides guilt, fines, probation, DUI programs, and possible jail — and it carries its own separate license consequences on conviction.
The DMV Administrative Per Se action is not a criminal matter at all. It's an administrative action taken by the Department of Motor Vehicles against your driving privilege alone, based on the arrest itself. No conviction is required. The DMV can suspend your license even if your criminal case is later dismissed or reduced.
Because these two tracks run separately, the outcomes don't automatically follow each other. You can win at the DMV and still fight the criminal charge, or beat the criminal case and still lose your license administratively if you did nothing about the APS action. They have to be handled as two parallel fights — ideally in a coordinated way, because what happens at the DMV hearing often previews the evidence in the criminal case.
What "Admin Per Se" Actually Means
"Per se" is Latin for "by itself" or "in itself." In DUI law, "per se" refers to the rule that driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal in itself — the prosecution doesn't have to prove you were actually impaired, just that your BAC was over the limit.
"Administrative Per Se" applies that same idea to your license. Under California Vehicle Code section 13353.2, the DMV will suspend the driving privilege of anyone arrested for DUI who either had a BAC at or above the legal limit or refused chemical testing. It's "administrative" because the DMV — not a judge — imposes it, and "per se" because it's based on the BAC number or the refusal itself, independent of the criminal outcome.
The BAC thresholds that trigger an APS action are:
- 0.08% or higher for drivers 21 and over
- 0.04% or higher for commercial drivers
- 0.01% or higher for drivers under 21 or anyone on DUI probation
A chemical test refusal triggers an APS action too — and refusal carries longer, harsher suspension penalties than a failed test.
The Pink Piece of Paper: Your Notice and Your Warning
When you're arrested for DUI in California, the officer typically confiscates your plastic driver's license on the spot and hands you a pink document — the Notice of Suspension and Temporary Driver License, Form DS-367.
That single form does three jobs at once:
- It serves as your official notice that the DMV intends to suspend your license.
- It acts as a temporary license that keeps you legal to drive for 30 days from the date of arrest.
- It contains your only written warning about the 10-day deadline to request a hearing.
Do not mistake the 30-day temporary license for a 30-day deadline. The temporary license buys you 30 days of driving, but the window to fight the suspension is only ten days. Many people lose their licenses simply because they saw "30 days" on the form and assumed they had a month to act.
The Deadline That Decides Everything: 10 Days
Here is the rule that matters more than any other in this article: you have 10 calendar days from the date of your arrest to request an APS hearing with the DMV.
Ten calendar days — not business days. Weekends and holidays count. If you do nothing within that window, the DMV suspension takes effect automatically once your 30-day temporary license expires, and in most cases there is nothing you or an attorney can do to reopen the hearing after the deadline passes. The ten-day rule is hard, and it is enforced strictly.
To request the hearing, you (or your attorney) contact the DMV Driver Safety Office that serves the county where you were arrested — the office is identified on your DS-367 — or call the DMV at 1-800-777-0133. Most DUI attorneys will make the request for you the same day you call.
There are two major reasons to request the hearing immediately, beyond just meeting the deadline:
It stays your suspension. Once you timely request a hearing, the DMV extends your driving privilege beyond the original 30 days until the hearing is held and decided. Instead of losing your license in a month, you keep driving while the process plays out.
It's your best window into the evidence. The APS hearing forces the DMV to disclose the police reports, the DS-367, chemical test results, and your driving record. That early look at the government's evidence frequently reveals weaknesses that help in the criminal case too.
What Happens at the APS Hearing
An APS hearing is not a trial, and it doesn't take place in a courtroom. It's an administrative proceeding conducted by a DMV Driver Safety Hearing Officer — a DMV employee, not a judge. Hearings today are usually held by phone or video, so you often don't have to appear in person at all.
The hearing is deliberately narrow. In a standard case where you submitted to a breath or blood test, the hearing officer decides just three questions:
- Did the officer have reasonable cause to believe you were driving under the influence?
- Were you lawfully arrested?
- Was your BAC 0.08% or higher (or the applicable lower limit) at the time of driving?
If you refused chemical testing, the third question changes: instead of your BAC, the issue becomes whether you were properly advised of the consequences and whether you in fact refused.
The DMV only has to prove these points by a preponderance of the evidence — "more likely than not." That's a much lower standard than the "beyond a reasonable doubt" required to convict you in criminal court, and the rules of evidence are relaxed, so the hearing officer can rely on hearsay like the police report. This is part of why experienced representation matters: the deck is structurally tilted toward the DMV, and challenging the evidence effectively takes knowledge of where these cases break down.
At the hearing, you have the right to review and challenge the DMV's evidence, cross-examine any witnesses, present your own evidence and testimony, and argue that one of the three findings can't be sustained. Afterward, the hearing officer will sustain (uphold), modify, or rescind (set aside) the suspension.
If You Win — and If You Lose
If the suspension is set aside, your driving privilege is protected from that administrative action, and the DMV license consequence goes away. Your criminal case still has to be resolved separately.
If the suspension is sustained, it takes effect. The length depends on your history and whether the case involved a test failure or a refusal. If you disagree with the decision, you generally have a limited time to file a Request for Administrative Review through the DMV, or to challenge the ruling by filing a Writ of Mandate in the Superior Court. Both routes have their own strict deadlines.
After an APS suspension, reinstating your license typically requires paying a reissue fee, filing proof of financial responsibility (an SR-22) and maintaining it for three years, and — in many cases — satisfying California's ignition interlock device (IID) requirements. California's IID and restricted-license rules have tightened in recent years, and the specifics depend on your offense and history, so this is an area where current, case-specific advice is essential rather than relying on general summaries.
Why the First 10 Days Decide So Much
Most negative DMV outcomes don't come from overwhelming evidence — they come from missed deadlines and procedural missteps in those first crucial days. By the time many people think to call a lawyer, days of the ten-day window are already gone.
If you've been arrested for DUI, treat the APS clock as the most urgent thing on your plate. Requesting the hearing costs you nothing but protects your ability to drive, forces the DMV to show its hand, and keeps every option open. Waiting does the opposite.
Frequently Asked Questions
How long do I have to request a DMV hearing after a DUI arrest in California?
You have 10 calendar days from the date of your arrest to request an Administrative Per Se (APS) hearing with the DMV. Weekends and holidays count. If you miss the deadline, the suspension generally takes effect automatically and cannot be contested, so it's critical to act immediately.
Is the DMV hearing the same as my criminal court case?
No. They are two separate proceedings. The DMV Admin Per Se action affects only your driving privilege and is based on the arrest itself, while the criminal case is prosecuted in court and decides guilt and penalties. You can win one and lose the other, which is why both should be handled together.
What does the DMV have to prove at an APS hearing?
In a standard chemical-test case, the hearing officer decides three issues by a preponderance of the evidence: whether the officer had reasonable cause to believe you were driving under the influence, whether you were lawfully arrested, and whether your BAC was 0.08% or higher (or the lower limit that applies to you). In a refusal case, the third issue is whether you were properly advised and actually refused testing.
Will I lose my license right away after a DUI arrest?
Not immediately. The pink Form DS-367 the officer gives you acts as a temporary license for 30 days from arrest. If you request a hearing within the 10-day window, the DMV extends your driving privilege until the hearing is decided. If you do nothing, the suspension begins when the 30-day temporary license expires.
What happens if I refused the chemical test?
A refusal triggers its own APS action with longer, harsher suspension penalties than a failed test, and it changes what the DMV must prove at the hearing. Refusal cases are handled differently and should be reviewed by a DUI attorney as soon as possible.
Can I appeal if I lose the DMV hearing?
Yes. You can file a Request for Administrative Review with the DMV or a Writ of Mandate in the Superior Court, but both have strict, short deadlines. An attorney can advise which route fits your case and preserve the deadline.
