If you’re asking what happens when you get a DUI in California, you’re not alone. A DUI can trigger two separate processes that both affect your freedom and your driver’s license. This guide explains the steps, the penalties, and the most important deadlines in plain language.

The two cases that start after a DUI arrest

Imagine your life getting “split in two” right after you get arrested. One case is in criminal court, and the other is at the DMV.

At a glance

After a DUI arrest Where it happens Main focus Can they fine or jail you
Criminal DUI case Court Whether you committed a DUI crime Yes (jail and fines)
DMV administrative case DMV hearing Whether your license should be suspended or revoked No (DMV can only act on your license)

The DMV process is often called APS (Administrative Per Se). It can move fast, while the court case moves on its own timeline.

The first hours after arrest

Officers must have an observable reason to stop you

Before an officer can pull you over for a suspected DUI, they generally need to observe a vehicle code violation (for example speeding or weaving, or sometimes something small like a missing license plate placement). Then they look for signs that your driving might be impaired by alcohol or drugs.

Signs officers look for

Officers commonly look for objective signs such as:
- slow or slurred speech
- red or watery eyes
- odor of alcohol on your breath

Field sobriety tests and the “pen test”

Officers typically run standardized field sobriety tests (FSTS). One well-known test is the horizontal gaze nystagmus test, often called the pen test.

What the pen test is trying to find

The purpose is to see whether your eyes track in a way that may indicate impairment. It’s not about guessing—officers are looking for specific eye movement patterns.

Other standardized field sobriety tests

You may also be asked to do tests such as:
- walk-and-turn (often 9 steps out, turn, 9 steps back)
- one-leg stand
- a timed counting task (commonly described as a 30-second count)

These tests can be difficult even when someone feels nervous or has balance issues.

The PAS test versus the later breath or blood test

PAS device

A Preliminary Alcohol Screening (PAS) test uses a handheld device. In many situations, it’s described as optional, but people may feel pressured to take it.

Chemical test at the station

A later breath test or blood test is the formal test used to determine BAC. The big idea is:
- PAS may be a quick screening step
- the station test (breath or blood) is the one that carries major legal consequences

Refusing chemical tests in California

If you refuse a chemical breath or blood test, the DMV consequences can be serious.

If you refuse or fail a chemical test

DMV treats refusal/failure as grounds for longer suspension or revocation, depending on age and offense history.

Situation DMV action if you refused or failed
Age 21+, first offense within the APS rules 1-year suspension
Age 21+, second offense within 10 years 2-year revocation
Age 21+, third/subsequent within 10 years 3-year revocation
Under 21 Different rules apply, but refusals/failures can still lead to 1-year suspension or longer penalties depending on prior offenses

How long a DUI arrest takes in Los Angeles

Processing can vary a lot. In one common description of Los Angeles DUI procedures, processing may take 3 hours to 24 hours before release with paperwork and next steps.

The “10-day clock” for your DMV hearing

This is one of the biggest pain points for people. Imagine thinking you can “handle it later,” and then learning the DMV deadline passed. In California, that mistake can be expensive.

What the DMV requires

  • The officer issues a suspension order and temporary documents.
  • You must request a DMV hearing within 10 days to challenge the suspension or revocation.

What happens if you miss the deadline

If you don’t request the DMV hearing in time, the DMV action generally goes forward automatically (so your license gets suspended or revoked).

Criminal court case versus DMV hearing

This question matters because people often assume one result automatically fixes the other.

What a DMV hearing decides

At the DMV hearing, DMV typically focuses only on whether:
- the officer had reasonable cause to believe you were driving under DUI laws
- you were placed under lawful arrest
- for a test case, your BAC met the threshold (commonly 0.08% for age 21+)
- for refusal cases, whether you refused after being properly told about the consequences

What the DMV does not decide

The DMV hearing is not a “guilty or innocent” trial. It’s about whether your license action is justified based on the officer’s report and test facts.

What penalties a first-time DUI can include

A first-time DUI is usually a misdemeanor in California, but the consequences still add up fast. A common description of typical impacts includes:

Common first-offense outcomes

  • Probation (often described as 3 to 5 years, commonly around 3)
  • DUI school (often 3 to 9 months, commonly around 3)
  • Fines plus penalty assessments that can total roughly $1,500 to $2,000 depending on the county
  • License suspension often described as 6 months (with possibilities for restricted driving)
  • Possible jail time in some counties (sometimes described as up to 6 months, depending on circumstances)
  • Ignition interlock device (IID) for about 6 months in many situations

Mandatory probation conditions for a first-time DUI

Probation comes with rules the judge must impose. Mandatory terms commonly include:

  • You may not drive with any measurable amount of alcohol in your blood
  • You must not refuse a chemical test if you’re later arrested for a DUI
  • You must install an IID for about 6 months
  • You must not commit any additional crime

What happens if you violate probation

If you violate DUI probation, the court can revoke probation and may bring back consequences that include jail time.

Can your license be restricted after a first-time DUI

A restricted license is a practical question for real life: getting to work, medical appointments, and necessities.

Key points about restricted driving

  • A request for a restricted license is not decided inside the DMV hearing itself.
  • Restricted license options may depend on whether it’s an injury case, and whether you are a first offender.
  • An IID may be part of the eligibility pathway.

How refusing affects the suspension length

Refusal/failure tends to be treated worse than a completed test because it removes one key data point (BAC). Under APS rules, refusal can mean a 1-year suspension for a first offense (age 21+), and longer actions for later offenses within 10 years.

What the DMV considers in your suspension hearing

This is the exact checklist DMV uses.

If you took a chemical test

DMV focuses on:
1. whether the peace officer had reasonable cause to believe you violated DUI laws
2. whether you were placed under lawful arrest
3. whether you had BAC over the legal limit at the time of driving

If you refused or failed the test

DMV focuses on:
1. whether the peace officer had reasonable cause
2. whether you were placed under lawful arrest
3. whether you were warned that refusal could lead to a 1-year suspension or a longer revocation period
4. whether you actually refused or failed after being asked

Two important “myths” people believe

Myth 1: If you win in criminal court, the DMV automatically drops the suspension

Usually the DMV suspension is reversed if DMV determines the court result truly equals an acquittal (not just a technical win).

Myth 2: If the charge is reduced to reckless driving, DMV must reinstate the license

No. A reduction to reckless driving often does not automatically change the DMV administrative action.

Expungement after a first-time DUI

People want to know whether a DUI can be “wiped away.”

What expungement generally means in California

  • A DUI typically stays on your record unless it is expunged.
  • Expungement is often possible after probation ends.
  • A common timeline described is about 3 years of probation, and then expungement may be possible.

Benefit of expungement

When a case is expunged, it can show as dismissed in your criminal record, and you may not need to disclose it the same way for many job or rental applications (though disclosure rules can still depend on the exact context).

Aggravating factors that can increase penalties

A “first-time” DUI can still be much worse if there are aggravating facts. Common examples include:
- injury to someone
- evidence suggesting higher impairment or dangerous driving
- refusal to cooperate with testing (which can affect DMV outcomes)
- any prior offenses within the look-back window (see next section)

“Priorable for ten years” and why timing matters

California treats DUI offenses as priorable for 10 years. That means a later DUI can be charged as a second or third offense even if the first conviction was years ago.

Simple example

If you got a DUI in 2012 and another in 2022, and they occurred within that 10-year window, the second arrest may count as a second DUI under California law.

First-time DUI versus second and third offenses

Penalties can increase a lot with a prior.

Category 1st DUI in 10 years 2nd DUI in 10 years 3rd DUI in 10 years
Jail Up to 6 months 96 hours to 1 year 120 days to 1 year
Probation 3 to 5 years 3 to 5 years 3 to 5 years
License suspension 6 or 10 months 2 years 3 years
IID 6 months 1 year 2 years
DUI school 3 or 9 months 18 or 30 months 30 months

DUI with injury in California

When a DUI involves injury, it can carry harsher outcomes than a typical first offense.

A common legal breakdown describes:
- misdemeanor DUI with injury consequences can include additional jail and probation terms depending on the situation

Because injury can raise both criminal and sentencing seriousness, it’s one of the situations where the stakes jump quickly.

Alternative sentencing possibilities

Depending on the case and county, alternatives may be considered, such as:
- treatment-focused options
- structured probation programming

In some situations, courts and counties may also consider outcomes that avoid longer jail terms, especially when it fits public safety goals.

Indirect costs that often surprise people

Many people focus on jail or fines and forget the everyday costs.

Common indirect consequences include:
- higher car insurance premiums for years
- longer-term employment and scheduling strain while meeting DUI school, probation, and reporting requirements
- added pressure if you drive for work

A DUI case is not just paperwork. It involves:
- fast deadlines for the DMV hearing
- technical rules about chemical testing
- how facts like refusals and officer observations affect the outcome

In practical terms, strong representation can help you:
- avoid missed deadlines
- prepare arguments aimed at the DMV license issues and the court criminal issues
- respond to probation requirements correctly

Right after arrest, the choices you make can affect how things play out.

Do

  • be respectful to the officer
  • provide your license, registration, and insurance when required
  • cooperate appropriately with testing choices (for example, if you decide to take the station test)

Don’t

  • don’t refuse chemical breath or blood tests (refusal can lead to harsh penalties and longer suspensions/revocations)
  • don’t admit to drinking
  • don’t try to “game” the situation to reduce results
  • don’t blow into the handheld PAS device if you are trying to avoid creating damaging evidence early
  • don’t argue in a way that escalates the stop or creates more problems

The probation period and early termination

A common description for first-time DUI probation is about three years. Early termination can be possible in some situations, depending on the case and court approval, which can also connect to timing for expungement.

Quick summary of the most important deadlines and outcomes

Topic What to remember
DMV hearing request Must be within 10 days
DMV and court are separate DMV handles license; court handles criminal penalties
Refusal consequences Can lead to longer suspension or revocation
Probation Mandatory terms include DUI conditions and often an IID
Expungement Often possible after probation ends (commonly around 3 years)
Priorable window DUI priors can count for 10 years

Conclusion

Getting a DUI in California usually means your life changes in two tracks at once: the court track (criminal penalties) and the DMV track (your license suspension or revocation). The biggest early lever is the 10-day DMV hearing window, because it affects whether you can fight to keep driving sooner rather than later.
