First DUI in California: Exactly What Happens, Step by Step

You got arrested for a first DUI in California. Take a breath. Most first DUIs follow the same path, and knowing that path takes away a lot of the fear.

Here is the one thing that cannot wait: you have 10 days to save your driver’s license. Everything else can be handled step by step, but that clock is already running. Start there.

The 10-day rule. When you were arrested, the officer likely took your plastic license and gave you a paper permit. You have only 10 days from your arrest to call the DMV and ask for a hearing. If you miss it, your license is automatically suspended and you lose the chance to fight it. Do this first.

You now have two separate cases, not one

This surprises almost everyone. One DUI arrest creates two completely separate problems, handled by two different places:

The DMV case is about your driver’s license. The DMV does not care if you are guilty of a crime. It only cares about your license.
The court case is the criminal side, the one with a judge, possible fines, classes, and jail.

They run at the same time but do not talk to each other. You can win one and lose the other. That is why the 10-day DMV step matters on its own, no matter what happens in court later.

Step one: the 10-day DMV deadline

Call the DMV Driver Safety office and ask for a hearing within 10 days of your arrest. Doing this does two good things: it puts your license suspension on hold until the hearing, and it gives you (or a lawyer) a chance to fight the suspension.

If you do nothing, the suspension kicks in automatically on the 30th day after your arrest. There is no grace period and no extension.

What you are facing in court (first offense)

For a typical first DUI, here is what the law allows. “Allows” is the key word, most first-time cases do not end up at the harsh end of these ranges.

Jail: the law allows anywhere from 96 hours up to 6 months, but breathe: in real life, people rarely, if ever, serve jail time on a clean first DUI beyond the arrest itself. The night you were booked is typically the only custody you’ll see. First offenses resolve through probation.
Fine: the base fine is $390 to $1,000, but with the state’s add-on fees the real total usually lands somewhere around $2,000 to $3,600.
DUI class: a 3-month program is standard. If your blood alcohol was 0.15% or higher, or you refused the test, it jumps to a 9-month program.
Probation: usually 3 to 5 years of informal probation. The main rules are simple: don’t drive with any alcohol in your system, don’t refuse a test if you’re stopped again, and don’t pick up new charges.

Jail (Vehicle Code 23536). A first DUI is punishable by 96 hours to 6 months in county jail, and if any jail is imposed, at least 48 of those hours must be served in a row. The court is supposed to try to schedule jail on your days off if possible.

Fines and fees (Vehicle Code 23536). The statute says $390 to $1,000, but California adds mandatory “penalty assessments” (court, county, and state surcharges) on top. These multiply the base fine several times over, which is why the real bill is usually a few thousand dollars.

DUI education (Vehicle Code 23538). If you get probation, you must finish a licensed DUI program. The standard first-offender program runs about 3 months. A blood alcohol of 0.15% or more, or a test refusal, bumps you to a 9-month program.

Probation (Vehicle Code 23600). Probation runs 3 to 5 years. Required conditions include: not driving with any measurable alcohol in your blood, not refusing a chemical test if you’re arrested again, and not committing any new crime. If you violate probation with a blood alcohol over 0.04%, the court must add at least 48 hours of jail.

What happens to your license

A first DUI conviction leads to a 6-month license suspension from the DMV. The good news for most people: you usually don’t have to go without driving for those months.

Since 2019, you can typically get back on the road right away with a restricted license if you install an ignition interlock device (IID), a small breath tester wired to your car that won’t let it start if it detects alcohol. For a first offense, the IID period is usually about 6 months. You’ll also need to enroll in your DUI class, carry special (SR-22) insurance, and pay the fees.

There are actually two suspensions floating around, because of your two cases. The DMV’s administrative suspension (from the arrest) runs about 4 months for a first offense if you don’t go the IID route. The court-ordered suspension (from a conviction) runs 6 months. They can overlap.

The simplest path for most first offenders is the IID restricted license: enroll in the DUI program, install a certified IID and file the paperwork, get your SR-22 insurance, pay the fees, and you can generally drive without a “hard” no-driving period. Talk to a lawyer or the DMV about the exact steps for your case, because the timing depends on both cases.

If you refused the breath or blood test

California has an “implied consent” law: by driving, you already agreed to take a chemical test if you’re lawfully arrested for DUI. Refusing has its own separate penalties, and they are harsher than the DUI itself in one key way.

Refusing costs you more, and there’s no restricted-license workaround. A first refusal means a 1-year license suspension with no restricted license to drive during it. Refusal also adds mandatory penalties if you’re convicted, and the prosecutor can tell the jury your refusal suggests you knew you were drunk.

What is a “wet reckless”?

You may hear this term. A “wet reckless” is a reduced charge a prosecutor may offer instead of a DUI, where you plead to reckless driving that involved alcohol. It is usually a better deal, but it is not a free pass.

The upsides: no mandatory minimum jail, lower fines, a shorter class, usually no automatic license suspension from the court, and often no required IID. The catch: if you get another DUI within 10 years, that wet reckless still counts as a prior DUI, so the next one is treated as a second offense.

What we see in real cases

A few realities that help set expectations:

Jail is almost never part of it. On a clean first DUI, people rarely, if ever, serve time beyond the arrest itself. Probation, the fine, and the class are the real sentence.
Most first DUIs end in a negotiated plea, not a trial. The negotiation is where the outcome gets decided.
The lower your BAC, the better your odds of a wet reckless. Reductions also come easier with a clean record and no accident.
Treat it as a wake-up call, visibly, even if you’re sure it wasn’t one. Here’s something people don’t expect: DAs tend to read a DUI as a sign of a drinking problem, even when it truly was a one-time mistake. The people who get the best outcomes are the ones who act on that assumption instead of fighting it. Start going to AA or a similar program, get an alcohol assessment, do something concrete that shows the problem, if there was one, is being handled. Bring proof of it to court. It genuinely moves prosecutors and judges.
Expect the whole process to take 6 months to a year. It depends on how clogged the court is, and right now the backlogs are significant. Long stretches of silence between court dates are normal, not a bad sign.
A private attorney often makes the case run slower, and that’s not a bad thing. Good lawyers take time to get the discovery (the police reports, video, and test records) and actually review it. Thorough is slow.
The 10-day trap is real. The license side can be lost by simply missing the DMV deadline, even when the court case goes fine. Don’t let that happen.

And if the wake-up call turns out to be real, that’s not a bad ending. Our Road Back section is written for exactly that.

Do you need a lawyer for this?

A first DUI is one of the most common cases in California courts, and many are very defendable. Even setting aside the criminal side, a lawyer can handle the DMV hearing, argue for a reduction like a wet reckless, and often keep you driving with minimal disruption.

At the very least, request that DMV hearing within 10 days yourself if you’re not going to talk to a lawyer right away. That deadline waits for no one.
