Dismissing a California DUI: What Actually Changes

Yes, a California DUI conviction can be dismissed after probation. But “can” is doing a lot of work in that sentence -- it is discretionary, not automatic, and it does not touch your driving record the way people hope.

Updated October 10, 2026

A DUI conviction (Vehicle Code § 23152 or § 23153) is not automatically excluded from dismissal relief in California, but it is treated differently than most other misdemeanors, in three specific ways worth understanding before you file anything.

It is discretionary, not automatic

For most misdemeanors, a court generally must grant a Penal Code § 1203.4 dismissal once probation is successfully completed and the other conditions are met. DUI offenses do not get that same guarantee. Penal Code § 1203.4(c)(1) carves out offenses described in Vehicle Code § 12810(a)-(e), which includes DUI, from the dismissal provision's automatic application. Instead, § 1203.4(c)(2) gives the court discretion: if a person convicted of one of these offenses petitions, “the court in its discretion and in the interest of justice, may order the relief.” That is a real difference -- the judge can say no, in a way they generally cannot for an ordinary misdemeanor with completed probation.

It does not touch your driving privilege

In other words, whatever the DMV did to your license because of the DUI stays done. A court dismissal of the criminal case has no effect on a license suspension or revocation. That is handled entirely through the DMV's own administrative process, separate from the criminal court.

It does not make the DUI disappear for future sentencing

This is the part that surprises people most. If you are ever convicted of another DUI within ten years, the earlier dismissed conviction still counts as a prior for sentencing purposes. Vehicle Code § 23622(a) is explicit: when a person is convicted of a DUI offense and had a separate qualifying conviction within the preceding ten years, “the court shall not strike any separate conviction of those offenses for purposes of sentencing in order to avoid imposing” the mandatory minimum penalties that come with a repeat offense. A dismissal under § 1203.4 is not a way to make a prior DUI stop counting as a prior.

If you hold a commercial driver's license, there is a fourth layer

Federal law adds a rule specific to commercial driver's license (CDL) holders. Under 49 C.F.R. § 384.226, a state “must not mask, defer imposition of judgment, or allow an individual to enter into a diversion program that would prevent a CLP or CDL holder's conviction for any violation ... of a State or local traffic control law ... from appearing on the CDLIS driver record.” A DUI is squarely the kind of traffic conviction this rule covers. California cannot hide a CDL holder's DUI conviction from the national commercial driver record, regardless of what happens in the criminal case.

What about a “wet reckless”?

A “wet reckless” is a lesser charge -- reckless driving involving alcohol -- that a DUI is sometimes negotiated down to. It generally falls into the same priorable category of Vehicle Code offenses as a full DUI conviction, which means the same three limits above apply to it in largely the same way: a court has discretion rather than a mandatory duty to dismiss it, dismissal does not touch any license action the DMV already took, and a wet reckless can still count as a prior if another qualifying offense follows within the statutory window. Do not assume a lesser charge escapes the rules that apply to DUI dismissals generally -- ask specifically about your exact conviction.

If you have more than one DUI on your record

Multiple DUI convictions raise the stakes in two ways. First, as explained above, an earlier conviction within ten years keeps counting against you for sentencing on a later one, dismissal or not (Vehicle Code § 23622(a)). Second, a fourth DUI within ten years, or a DUI involving injury to another person, can be charged as a felony rather than a misdemeanor under separate Vehicle Code provisions. A felony DUI sits in a different procedural category than a misdemeanor one -- the dismissal analysis under Penal Code § 1203.4 still applies once probation is completed, but a felony conviction carries its own additional consequences, including the firearm restrictions covered in our guide on expungement and gun rights, that a misdemeanor DUI does not.

So why bother at all?

Because, even with all three limits above, a court dismissal still has real value for many people. The benefits a § 1203.4 dismissal does provide -- the ones that apply to any dismissal, not specific to DUI -- still apply: employers covered by the Fair Chance Act generally cannot consider a dismissed conviction, and the case carries a different legal status than an unresolved conviction for most purposes outside of driving privileges and future DUI sentencing. The point is simply to go in with the right expectations about which parts of the problem a dismissal actually solves.

A DUI petition is also where the discretionary standard discussed in our guide on probation violations tends to come up most often, since DUI probation frequently comes with strict conditions -- alcohol education programs, ignition interlock requirements, abstinence conditions -- that are easier to slip on than ordinary misdemeanor probation. A violation during DUI probation does not close the door on a later dismissal petition, but it does shift the court's decision from something closer to automatic into something the judge is actually weighing, for the same reasons explained in that guide.
