First-Time DUI in California: What to Expect in

A first DUI in California can create immediate legal problems in two places at once. The DMV can move to suspend your driving privilege while the criminal case moves through the court system.

The two proceedings follow different rules, deadlines, and consequences, and what you do in the first days after an arrest can affect both.

Under California Vehicle Code section 23152, a standard first DUI is generally charged as a misdemeanor. That does not make the case minor. A conviction can affect your license, finances, insurance, employment, and driving record for years. At the same time, a first offense follows a defined legal process, and understanding what happens next can make the situation easier to navigate.

Brown & Stedman LLP has decades of experience helping Orange County clients understand what follows a DUI arrest and what options may be available. Here is what you can expect from the first days after an arrest through sentencing and probation.

Key Takeaways

• A standard first DUI under California Vehicle Code section 23152 is generally a misdemeanor.
• The DMV hearing deadline is critical. In most cases, you have 10 days from the arrest to request a hearing to challenge the administrative license suspension.
• The statutory base fine for a first DUI is $390 to $1,000, but assessments and other costs can make the total substantially higher.
• Jail is legally available for a first DUI, although the outcome depends on the facts of the case and any aggravating circumstances.
• DUI does not currently qualify for California’s general misdemeanor judicial diversion process.
• Ignition interlock requirements depend on the circumstances, county, and applicable law, so it is important to understand what applies to your case rather than relying on a general rule.

What Happens After a First-Time DUI Arres

A DUI arrest can set two separate processes in motion. The criminal case is handled through the court, while the DMV separately addresses your driving privilege. These proceedings are related, but one does not replace the other.

Chemical Testing and Booking

After a DUI arrest, officers generally require chemical testing under California’s implied-consent laws. Depending on the circumstances, that may involve a breath or blood test.

Refusing a chemical test does not make the DUI case disappear. A refusal can lead to separate DMV consequences and may also become relevant in the criminal case. The consequences can be particularly serious because the DMV process operates independently of what happens in court.

You may also receive a temporary driver’s license or other documentation following the arrest. That paperwork is important because it helps establish the timeline for the DMV process.

The 10-Day DMV Deadline

One of the most important deadlines comes before you ever appear in court.

In many DUI arrest situations, you have 10 days from the date of arrest to request a DMV administrative hearing. If you do not request the hearing within that period, the DMV can proceed with the suspension without giving you the opportunity to challenge it at a hearing.

That deadline is separate from your criminal court case. You should not assume that waiting for your arraignment protects your driving privileges.

Because the deadline is short, speaking with an Orange County DUI attorney promptly can help you understand what needs to happen before it expires.

How Much Does a First DUI Cost in California

The financial consequences of a DUI can extend beyond the fine imposed by the court.

California Vehicle Code section 23536 establishes a $390 to $1,000 base fine for a first DUI conviction. Court assessments, penalties, fees, DUI education, and other expenses can significantly increase the amount you ultimately pay.

The California DMV’s first-offender information provides additional information about the consequences of a first DUI.

Depending on the circumstances, you may face costs such as:

• Fines and assessments: The statutory base fine is $390 to $1,000, with additional assessments potentially increasing the total substantially.
• DUI education: A court may require completion of an approved alcohol and drug education program. The length can depend on factors such as the circumstances of the offense and blood alcohol concentration.
• Ignition interlock costs: If an ignition interlock device is required or ordered, you may be responsible for installation, monitoring, and monthly maintenance expenses.
• Insurance: A DUI conviction can result in significantly higher auto insurance premiums and may affect your ability to obtain coverage at the same rate.

The actual financial impact depends on the charge, the facts of the arrest, and the outcome of the case. That is why looking only at the court’s base fine can give you an incomplete picture.

How License Suspension Works

The DMV can suspend your driving privilege based on the DUI arrest, while the court can impose additional consequences following a conviction. These processes operate independently, which is one reason the first days after an arrest matter so much.

For many first-offense DUI cases, the DMV administrative suspension period and court-imposed suspension consequences can overlap rather than simply add together. Depending on your circumstances, you may also have an opportunity to obtain a restricted driving privilege, including through an ignition interlock device.

The rules are fact-specific, including whether you submitted to chemical testing, your prior DMV history, and whether an ignition interlock requirement applies.

Because the DMV deadline can expire before your criminal case gets underway, the license issue should be addressed separately rather than left until your first court appearance.

Will You Go to Jail for a First DUI

California law allows county jail as a possible punishment for a first DUI. That does not mean every person convicted of a first DUI will serve time.

The facts surrounding the arrest can make a significant difference. A straightforward first offense may be treated very differently from a case involving a high BAC, a collision, injuries, a child passenger, a chemical-test refusal, or other aggravating circumstances.

The same is true of the person’s prior record and the way the case is ultimately resolved. Probation, DUI education, fines, and other conditions may be imposed instead of jail in an appropriate first-offense case.

The important point is that “first DUI” does not automatically tell you what your sentence will be. The specific facts need to be evaluated before you can meaningfully assess your exposure.

Where DUI Diversion and the Interlock Rules Stand in 2026

Right now, a first-time DUI does not qualify for judicial diversion, even though it looks like it should, and the ignition interlock device gets described online as more mandatory than the law makes it.

Diversion Still Doesn’t Apply to DUI

California’s general misdemeanor diversion laws can allow eligible defendants to complete a program and potentially have the case dismissed. DUI charges, however, are treated differently.

California Vehicle Code has long restricted diversion for DUI offenses. As of 2026, a standard first-time DUI should not be approached with the assumption that judicial diversion will lead to dismissal.

If avoiding a DUI conviction is important to you, the available defenses and potential resolutions need to be evaluated based on the evidence in your individual case.

The Interlock Device Isn’t Automatically Mandatory for a First Offense

Ignition interlock rules have changed over time, which is one reason online DUI information can be confusing.

An ignition interlock device is not simply a universal requirement that applies identically to every first DUI throughout California. Requirements can depend on the county, the circumstances of the offense, the court’s order, and the driver’s eligibility for a restricted license.

California’s current rules also distinguish between situations where an interlock is mandatory and those where a court has discretion to order one. Assembly Bill 366, signed in 2025, extended California’s ignition-interlock framework through January 1, 2033.

If an interlock is ordered or required in your case, you generally must have the device installed and comply with its operating requirements to maintain the applicable driving privilege.

Violations can create additional problems, so understanding the requirements before driving is important.

What Probation and the Interlock Requirement Look Like

If your case ends in a conviction, probation can become one of the most important parts of the sentence.

Common conditions for a first DUI may include:

• Informal probation: You may be placed on probation without regularly reporting to a probation officer.
• DUI education: You may have to complete an approved program within the required timeframe.
• No new DUI violations: You will be required to comply with California’s laws concerning alcohol- and drug-impaired driving.
• Ignition interlock compliance: If an interlock is required or ordered, you must comply with the installation and operating requirements.
• Other court conditions: Depending on the case, the court may impose additional terms.

You may also receive a Watson advisement, which informs you that driving under the influence is dangerous and that a future DUI resulting in a death can lead to a murder prosecution.

Completing probation successfully matters. A violation can expose you to additional consequences and make a case more complicated.

FAQs

Q: How long does a DUI stay on your driving record in California?

A: A DUI conviction generally remains on your California DMV record for 10 years for purposes of counting prior DUI offenses. A second DUI during that period can carry harsher penalties.

Q: Can you get a restricted license right after a DUI arrest?

A: Possibly. Eligibility depends on your driving history, the circumstances of the arrest, and whether you meet the requirements for a restricted license. The 10-day DMV hearing deadline is an important first step.

Q: What’s the difference between a wet reckless and a DUI?

A: A wet reckless is a reduced alcohol-related reckless driving charge that can carry fewer consequences than a DUI. It still counts as a prior alcohol-related offense if you are charged with another DUI within the applicable period.

Q: Will a first DUI show up on an employer background check?

A: It can. A DUI conviction is generally a public court record and may appear on a criminal background check, particularly for jobs involving driving or other regulated responsibilities.

Q: Does a first DUI raise your car insurance rates?

A: It can. A DUI conviction may lead to higher premiums or make it harder to obtain coverage at the same rate, although the impact varies by insurer and your driving history.
