The part of a California DUI that disrupts life the fastest is usually the license. I am Joel Brand, and the call I most wish people made sooner is about the license, because it runs on a separate DMV track with its own short deadline, and missing that deadline costs you a hearing you were entitled to. The license case also interacts with the court case in ways that surprise people. This guide brings the license pieces together, with links to the detailed article and the free tool for each.

What you need to know first

  • You have 10 days from your arrest to demand a DMV hearing. Miss it and the suspension takes effect automatically.
  • The officer takes your plastic license and gives you a pink Notice of Suspension (form DS-367) that works as a 30-day temporary license.
  • For a first offense with a BAC of 0.08% or more, the DMV imposes a 4-month administrative suspension. By installing an ignition interlock device you can usually drive immediately, anywhere, for the entire period.
  • Refusing the chemical test triggers a 1-year suspension with no restricted-license option, on top of the criminal case.
  • A court conviction carries its own suspension (6 months for a first offense) that runs concurrently with the DMV action.
  • A California DUI stays on your driving record for 10 years.

Two separate cases, one arrest

The single most important thing to understand about a DUI is that one arrest sets off two completely separate proceedings. The first is the criminal case in court, where a judge and prosecutor decide guilt and punishment. The second is the administrative case at the DMV, which deals only with your driving privilege and is decided by a DMV hearing officer, not a judge. They have different rules, different burdens of proof, and different timelines. You can win one and lose the other. Many people focus entirely on the court date and never realize the DMV case even exists until the suspension hits, by which point the 10-day window to fight it has closed. Treating the license case as its own fight, immediately, is what protects your ability to drive.

How long is the suspension?

Situation (priors within 10 years)License actionDriving option
First offense, BAC 0.08%+4-month DMV suspension; 6-month court suspension on conviction (concurrent)IID-restricted license, usually immediately
Second offense2-year suspensionConvertible to an IID-restricted license

Fourth offense4-year revocation; habitual traffic offenderLimited; depends on the case

Why the DMV hearing is worth demanding

Demanding the hearing does two things, even before it is held. First, it stays the suspension, so your temporary license keeps you driving until the hearing is decided. Second, it forces the DMV to prove its case, and that gives me a chance to win it outright on issues like a bad stop, a flawed breath result, or a defective DS-367. It also functions as free discovery: the testimony and documents from the hearing often help the criminal case. There is real value in having your attorney handle the hearing without you, so nothing you say can be used against you. The one thing you cannot do is wait, because the right disappears after 10 days.

Suspensions and getting back on the road

Even when a suspension takes effect, it rarely means you are completely off the road. Most first offenders qualify for an ignition interlock restricted license that lets them drive without limitation as long as the device is installed, and there are paths back to a full license once the suspension period and requirements are satisfied. The refusal suspension is the harsh exception, because it allows no restricted license. These articles explain the suspension statutes and the routes back to driving.

Ignition interlock and SR-22

Two requirements follow most DUI license cases: the ignition interlock device (IID), which you blow into before the car will start, and the SR-22, a certificate your insurer files to prove you carry the required coverage. Both have specific durations and rules, and both add cost, but the IID in particular is what lets most drivers stay on the road during a suspension.

Commercial and out-of-state drivers

Two groups face extra stakes. Commercial drivers can lose their commercial privilege for a year even on a first DUI, and even when the DUI happened in their personal vehicle, which can end a career. Out-of-state drivers face a California suspension that follows them home, because California reports the action and most states honor each other's suspensions through the Interstate Driver License Compact. If you were licensed in another state, getting the California DMV action resolved is essential to protecting your home-state license. See out-of-state license reinstatement.

What happens if you do nothing

The harshest outcomes I see come from inaction. If you let the 10 days lapse, the suspension takes effect automatically and you lose the chance to challenge it. If you drive on a suspended license, that is a new crime under VC 14601 with its own penalties and a likely longer suspension. And if you ignore the requirements for reinstatement, the suspension simply never ends. None of this is automatic the moment you act. Demanding the hearing, installing the IID, and following the reinstatement steps in order is what keeps a license problem from becoming a license catastrophe.
