Third DUI in California: Now a Wobbler/Felony

What “Third DUI” Legally Means

A “third DUI” is not simply your third lifetime arrest. Under Vehicle Code §23546, it is a DUI conviction that occurs within 10 years of two separate prior violations — or any combination of the following — that resulted in convictions:

• DUI — driving under the influence (Vehicle Code §23152)
• DUI causing injury (Vehicle Code §23153)
• Alcohol-related reckless driving, commonly called wet reckless (Vehicle Code §23103, as specified in §23103.5)

Three points people get wrong constantly:

• Wet reckless counts. Plenty of drivers who accepted a wet-reckless plea years ago believe it made their DUI “go away.” It didn’t. The conviction sits in the 10-year lookback and can push a later DUI straight into the third-DUI tier — and, from 2027, into the wobbler tier.
• Out-of-state priors may count. It generally does not matter if the two prior offenses happened in another state — California can treat them as priors for sentencing.
• Old priors age out of the count, not the record. A DUI more than 10 years old no longer counts as a prior for the charging tier, but it remains on your criminal record.

The statute frames the lookback in terms of violations “that resulted in convictions” within 10 years. Some defense sites describe it by arrest date and others by conviction date — the exact measuring point can matter in close cases, so use the statute’s phrasing and confirm the details with a lawyer. What is not in dispute: two qualifying convictions inside the window, and the next DUI is charged as a third.

This guide is general legal information, not legal advice. DUI cases turn on dates, priors, and local practice — consult a California criminal defense lawyer about your own case.

Court Penalties: Before vs. After AB 1546

The court track is where AB 1546 changes everything. Through the end of 2026, a third DUI in 10 years is a straight misdemeanor with a fixed range. From January 1, 2027, AB 1546 (Asm. Nick Schultz; Chapter 444, Statutes of 2026; signed September 25, 2026) turns it into a wobbler — meaning the prosecutor can file it as a misdemeanor or as a felony, and the judge can later reduce a felony wobbler to a misdemeanor under Penal Code §17(b).

Fine figures are the base statutory range. Penalty assessments roughly triple the courtroom total in most counties — see the cost section below for the bands.

What a felony conviction adds beyond the sentence. The difference between the two wobbler options is not just months vs. years. A felony DUI conviction can cost the 20% good-driver auto-insurance discount (AB 1546 conforms Insurance Code §1861.025), carries a lifetime firearm prohibition under Penal Code §29800 (verify the exact mechanics with counsel), and has employment, professional-licensing, and possible immigration consequences for non-citizens. That collateral weight is exactly why the charging decision — misdemeanor or felony — is the highest-stakes moment in a third-DUI case.

The Full Felony Ladder From 2027

AB 1546 doesn’t just touch the third DUI — it restructures the whole repeat-DUI charging ladder. This is the table no competitor has published, and it’s where several top-ranked law-firm pages are already wrong (some still claim “a fourth DUI is a felony” or “third DUI is always a misdemeanor” — both false from 1/1/2027).

The §23550.5 distinction, stated plainly. Vehicle Code §23550.5 is a different felony trigger from the ladder above: it applies to any DUI when the driver already has a prior felony DUI conviction — regardless of the count. It is not “the fourth-DUI rule.” AB 1546 conforms §23550.5 to reference the restructured tiers but doesn’t change its logic. Conflating “4th DUI in 10 years” (§23550(a), wobbler) with “DUI after a prior felony DUI” (§23550.5, always a public offense) is exactly where competitor pages and news blurbs get sloppy — don’t.

Note the fine the statute keeps identical across tiers: $390–$1,000 whether the case lands as a misdemeanor or a 16-month felony. The fine doesn’t scale with the wobbler choice — the custody exposure and the collateral consequences do.

The DMV Track: What AB 1546 Does NOT Change

Here is the single most misunderstood fact in third-DUI cases: the criminal court and the DMV run on separate tracks, and AB 1546 touches only the court track. A third-DUI arrest triggers a DMV APS (Administrative Per Se) action within days of the arrest — completely independent of whether the DA later files a misdemeanor, a felony, or nothing at all. Every figure in this table is current law, unchanged by the 2027 package:

About restricted-license timing: you will find conflicting figures online — 180 days here, 18 months there, some sources saying a third-DUI driver isn’t entitled to a restricted license at all. The honest answer is that eligibility timing depends on the facts of your case and the DMV’s current practice, which is why this guide does not print a single timing figure. What is solid: the IID-restricted path exists, the IID term runs about 2 years, and the exact start date should be confirmed with the DMV Driver Safety Office handling your case. Our ignition interlock device guide (publishing today) covers the IID mechanics in full.

The DMV’s 30-day temporary driving privilege matters here: when you’re arrested, the officer typically takes your license and hands you the pink DS 367 order, which doubles as a 30-day temporary license. That’s your bridge — but the bridge only works if you act on the 10-day clock below.

The 10-Day Clock: Your APS Hearing After a 3rd-DUI Arrest

Miss the 10-day deadline and the APS suspension takes effect automatically — no hearing, no second chance on the administrative track. With a third DUI, that means a 1-year APS suspension on top of everything else. Here’s the sequence:

Our APS hearing guide (publishing today) walks through the hearing issues, the evidence the DMV relies on, and what actually wins these hearings — including how the stakes change when the underlying arrest is a third DUI facing a 2027 wobbler filing.

Getting Back on the Road: Restricted License + IID

After the revocation period — or during it, through the restricted path — the route back to legal driving has three mandatory pieces: the DUI program, the ignition interlock device (IID), and the SR-22. None is optional, and the order matters.

• DUI program: a court-approved education program — reported at 30 months for a third DUI (defense-source reporting; the DMV doesn’t publish a single program-length figure). You’ll need proof of enrollment/completion (the DL-101 certificate path) for reinstatement steps.
• IID: required for the restricted license and generally kept for 2 years after a third DUI. Install, monthly monitoring, and calibration costs are yours — published install ranges run roughly $50–$170 with ~$60–$120/month monitoring (single-source ranges; actual quotes vary by installer).
• SR-22: 3 years of continuous coverage from reinstatement or the restricted-license date. A lapse restarts the clock — this is the most common way drivers turn a 3-year SR-22 into a 4-year one. Our SR-22 guide covers filings, costs, and non-owner policies.
• Reissue fee: $125 paid to the DMV when reinstating.

Edge case worth knowing: selling your car doesn’t erase the requirements — they follow the driver and the license, not the vehicle. Non-owner SR-22 policies exist for exactly this situation, and the IID requirement attaches to any vehicle you operate while on the restricted license.

Full IID mechanics — installers, costs, durations, calibration rules, and what violations do to your case — are in our ignition interlock device guide (publishing today).

What a Third DUI Actually Costs

No honest guide prints a single “a third DUI costs $X” figure — counties assess differently, program fees vary, and insurance math is personal. Here’s the honest structure, as low/high bands drawn from published defense-source ranges:

Bands are assembled from published defense-source ranges (fine/assessment figures from multiple firms; IID ranges single-sourced). Treat them as order-of-magnitude guidance — and note the 2027 wobbler adds a new cost axis: defending a felony filing is categorically more expensive than defending a misdemeanor.

One cost that’s structural, not discretionary: a felony third DUI (2027+) forfeits the 20% good-driver insurance discount under Insurance Code §1861.025 — a surcharge that compounds for years after the case ends.

What AB 1546 Does NOT Change

• First and second DUI penalties — unchanged.
• IID requirements and durations — unchanged (the separate IID pilot extension through 2033 comes from AB 366, a 2025 bill, not AB 1546).
• License revocation lengths — the 3-year revocation on a third-DUI conviction stands.
• DUI causing injury (VC §23153) — its own misdemeanor/felony structure is untouched.
• Retroactivity — nothing here reaches back. Offenses before 1/1/2027 are judged under the old law; only the charging tiers for new offenses change.

The companion bill worth knowing by name is Braun’s Law (SB 907, Chapter 443) — operative the same day. It doesn’t re-tier third-DUI charging, but it requires courts to give the formal Watson murder advisement when a DUI is pled down to a lesser offense. Practically, that means a wet-reckless plea now generates the paper trail that makes a later third-DUI wobbler case — and any future fatal-DUI prosecution — harder to defend. Our Braun’s Law guide covers that interplay.

Common Mistakes From Real Questions

• Missing the 10-day hearing deadline. The APS suspension then takes effect automatically — and with a third DUI it’s a full year. Calendar the deadline the day you get the pink order.
• Assuming the wet reckless “went away.” It counts as a prior in the 10-year lookback. More than one driver has been shocked to learn their “reduced” plea is what made the current case a third DUI — and from 2027, a wobbler.
• Assuming out-of-state priors don’t count. They generally can. Tell your lawyer about every prior conviction in every state.
• Trusting stale “4th = felony” pages. Under AB 1546 the 4th DUI stays a wobbler; the automatic felony is the 5th tier. Pages quoting nolo’s old “16 months to 4 years” phrasing are also stale — the triad is 16 months / 2 years / 3 years.
• Driving on a revoked license. Driving while your license is suspended or revoked for DUI (VC §14601.2) is its own misdemeanor — and for habitual traffic offenders (§14601.3) it escalates. The car can also be impounded.
• Confusing the two tracks. Beating the criminal charge doesn’t erase the APS suspension, and winning the APS hearing doesn’t stop the court case. They are separate proceedings with separate deadlines — treat them that way from day one.
