California DUI Laws Explained: Vehicle Code 23152 (2026 Guide)
If you or someone you love is facing a DUI in California, the law behind it can feel like a wall of code sections and deadlines. Here's the plain-English version: California's core DUI law is Vehicle Code 23152, which makes it illegal to drive under the influence of alcohol or drugs, and separately makes it illegal to drive with a blood alcohol concentration (BAC) of 0.08% or higher. A DUI sets off two separate processes — one at the DMV and one in criminal court — and almost every DUI reinstatement in California requires an SR-22 filing. This guide walks through what the law actually says, the penalties by offense, and where the SR-22 fits, without judgment. Everyone makes mistakes; our job is to help you understand the path forward.
TL;DR: VC 23152(a) covers driving impaired; VC 23152(b) covers driving with a BAC of 0.08%+. A DUI triggers a DMV Administrative Per Se (APS) suspension (from the arrest) and a criminal court case (from the conviction) that run on separate tracks. Penalties escalate with each offense within 10 years, and you'll generally need an SR-22 on file for about three years to reinstate. We handle the SR-22 part — often the same day.
What Vehicle Code 23152 actually says
California's DUI statute has two key subsections that are usually charged together:
- VC 23152(a) — it is unlawful to drive under the influence of any alcoholic beverage or drug. This is about actual impairment, and it can apply even when a BAC is below 0.08% if driving is affected (for example, by drugs or a combination).
- VC 23152(b) — it is unlawful to drive with a BAC of 0.08% or more. This is the "per se" limit: at or above 0.08%, the number itself is the offense, regardless of how well you felt you were driving.
Because these are separate theories, prosecutors often file both. A related section, VC 23153, covers DUI causing injury, which carries heavier penalties and can be charged as a felony.
California BAC limits by driver type
The 0.08% limit is the general rule, but California sets lower thresholds for certain drivers:
| Driver | BAC limit |
|---|---|
| Standard driver (21+) | 0.08% |
| Commercial driver (CDL) | 0.04% |
| Driver under 21 (zero tolerance) | 0.01% |
| Driver on DUI probation | 0.01% |
| Rideshare/taxi with passenger | 0.04% |
If you hold a commercial license, even an off-duty DUI can jeopardize your CDL — see our note on commercial drivers below.
The two cases against your license (this trips everyone up)
The single most confusing thing about a California DUI is that you are actually dealing with two separate proceedings that run on different tracks and have different rules:
- The DMV Administrative Per Se (APS) suspension. This is triggered by the arrest itself, not a conviction. When you're arrested for DUI with a BAC of 0.08% or higher, the officer typically confiscates your license and issues a temporary one. You have only 10 days to request a DMV hearing to contest the suspension. Miss that window and the suspension takes effect automatically. (This is the "10-day rule.")
- The criminal court case. This is the prosecution under VC 23152. A conviction brings court-ordered penalties — fines, a licensed DUI program, probation, possibly jail, and sometimes its own suspension.
These two actions overlap rather than stack, but you generally must satisfy both to drive legally again. Because the 10-day DMV hearing window is so short, contacting a qualified California DUI attorney quickly can matter. (We handle insurance and SR-22 filing, not legal defense — for the criminal case, talk to a DUI attorney.)
Penalties by offense (within 10 years)
California counts prior DUIs and "wet reckless" pleas within a 10-year lookback window. Penalties escalate with each offense. The table below shows the typical shape; your exact outcome depends on BAC, injuries, and your record.
| Offense | DMV APS suspension | Typical DUI program | Ignition interlock (IID) |
|---|---|---|---|
| First DUI (no injury) | ~4 months | 3-month (30-hour) program (longer for high BAC) | Optional (~6-month IID lets you drive anywhere) |
| Second DUI (within 10 yrs) | ~1 year | 18-month program | ~1 year mandatory |
| Third DUI | Longer / possible revocation | 30-month program | ~2 years |
| Fourth or subsequent / injury | Longest / revocation; can be a felony | Extended | Up to 3 years |
Refusing a chemical (breath or blood) test adds its own suspension on top of the DUI — 1 year for a first refusal, 2 years for a second within 10 years, and 3 years for a third.
Fines are set by the court and vary widely; a first-offense DUI can run up to around $1,000 in base fines plus penalty assessments and fees that increase the real total, and a second offense can be higher. Jail exposure also rises with each offense.
DUI vs. wet reckless
Sometimes a DUI charge is plea-bargained down to a "wet reckless" — reckless driving involving alcohol under Vehicle Code 23103 per 23103.5. The court penalties are lighter and there's no mandatory court suspension, but here's the catch most people miss: the DMV's APS suspension is separate and can still apply, so a wet reckless often still requires an SR-22, and insurers frequently rate it much like a DUI. For the full comparison, see our guide to wet reckless insurance in California.
Ignition interlock under SB 1046
Since SB 1046 took effect on January 1, 2019, an ignition interlock device (IID) — a small breathalyzer wired to your ignition — is part of many California DUI resolutions. For a first DUI with no injury, the IID is generally optional: install one for about six months and get an IID-restricted license that lets you drive anywhere, or take a non-IID restricted license limited to work and your DUI program (typically 12 months). Injury and repeat offenses carry mandatory IID terms of one to three years. Full details are on our California ignition interlock guide.
Where the SR-22 fits
If your DUI led to a suspension — and almost all do — California requires an SR-22 on file to reinstate your license. A few essentials every driver should know:
- An SR-22 is a certificate of financial responsibility your insurer files with the DMV to prove you carry at least the required liability coverage. It is not a policy or a DMV fee — it's a filing attached to a policy.
- California uses the SR-22 form — not FR-44 (FR-44 exists only in Florida and Virginia).
- You'll typically keep it active for three continuous years. A lapse triggers an SR-26 cancellation and can restart the clock, so keeping it active is essential.
- Your policy must meet California's current 30/60/15 minimum limits (effective January 1, 2025): $30,000 bodily injury per person, $60,000 per accident, and $15,000 property damage.
The SR-22 filing itself is inexpensive — often around $25, and in our experience the filing charge averages closer to $15 over a policy term. What raises your cost is the high-risk policy behind it, which is exactly why comparing carriers matters. For the complete after-DUI roadmap, see our pillar page, SR-22 after a DUI in California.
One timing tip that can save you money
Here's something California drivers rarely learn until it's too late: insurers are only allowed to rate and surcharge for offenses you've actually been convicted of — a pending charge can't be applied to your policy. So if you've been arrested but not yet convicted, locking in a 12-month policy before your conviction date can keep your rate based on your current record, potentially saving hundreds to thousands of dollars over the year (especially with a financed vehicle that already requires full coverage). If your court date is coming, it's worth a call before then.
Frequently asked questions
What is the BAC limit for a DUI in California? 0.08% for standard drivers 21 and older, 0.04% for commercial drivers, and 0.01% for drivers under 21 or on DUI probation. You can also be charged under VC 23152(a) for impairment even below 0.08%.
Is a first DUI a misdemeanor or a felony in California? A first DUI with no injury is typically a misdemeanor. A DUI can become a felony when it causes injury, on a fourth offense within 10 years, or if you have a prior felony DUI.
Do I need an SR-22 after a DUI in California? Almost always, yes. California requires an SR-22 on file to reinstate your license after a DUI, and it typically must stay active for three continuous years.
How long does a DUI stay on my record in California? A DUI conviction counts as a prior for 10 years for sentencing purposes and stays on your DMV record accordingly. Its heaviest insurance impact is usually in the first three years.
What's the difference between the DMV case and the court case? The DMV's Administrative Per Se suspension comes from the arrest and is handled by the DMV (you have 10 days to request a hearing). The criminal case comes from the VC 23152 charge and is handled by the court. They run separately but you must resolve both.
