AB 1546: California’s Third-DUI Felony Changes for 2027

Updated October 13, 2026 · JackDUI editorial team

Does AB 1546 make every third DUI a felony?

No. The amended section 23546 permits misdemeanor or felony punishment for a new DUI involving two qualifying prior violations within ten years that resulted in convictions. That is commonly called a wobbler. It does not mean every third DUI automatically becomes a felony.

The amended section 23550 retains misdemeanor-or-felony treatment for a new DUI with three qualifying priors and specifies felony punishment for a new DUI with four or more qualifying priors. Separate statutes can also affect exposure, including prior felony DUI and injury allegations. See the chaptered AB 1546 text.

Why offense dates and the final text matter

An earlier version of this article described the bill while it was pending. The Governor’s September signing announcement confirms that it was enacted. Signing a bill and a provision becoming operative are different events. Do not use an old committee analysis to calculate a current license or IID term.

The chaptered text includes conditional coordinating provisions involving AB 1830, including language referring to 2031. Which version operates depends on the conditions stated in the legislation. Counsel should check the operative code and companion legislation before advising on a particular sentencing or licensing consequence.

What records should a repeat-DUI defense review?

Start with the actual charging document and a clear timeline. A shorthand description such as “third offense” is not enough to evaluate the case. Useful records include:

• The date, court, case number, and disposition of each alleged prior.
• Plea and sentencing documents, including any wet-reckless disposition.
• Records of an out-of-state case that the prosecution proposes to use.
• The new citation, complaint, release conditions, and next appearance notice.
• DMV notices and current driving-status information.
• Available photographs, recordings, witness contacts, and testing records.

Ask counsel to explain which allegations are disputed, what proof is still missing, and how the defense will obtain it. A prior record does not answer whether the new stop, driving allegation, or chemical result is reliable. The new evidence needs its own review.

Questions to ask before discussing a resolution

• Which statutory version applies to the alleged offense date?
• Which prior cases are claimed to qualify, and what documents support that claim?
• What are the charged and realistically available sentencing options?
• Which license consequences are separate from the criminal sentence?
• What treatment, work, family, or other records should be gathered for counsel?

Keep copies of all notices and communicate changes in court dates or DMV correspondence promptly. Do not assume that negotiating the criminal case has resolved a separate administrative deadline.
