How Long Does a DUI Stay on Your Record in California?
There is no single answer, because a California DUI does not live on just one record. It actually touches three separate records, each with its own clock: how long the DUI can be used to increase penalties on a future case (the "priorable" period), how long it shows on your DMV driving record, and how long it stays on your criminal record. Understanding the difference matters, because the answer most people want — "when does it go away?" — depends entirely on which record you are asking about. Here is a plain-English breakdown of all three under current California law.
In this guide
When someone asks how long a DUI "stays on their record," they are usually thinking of one record. In reality, a California DUI conviction creates three overlapping timelines. Two of them generally run 10 years, but they are measured differently and do different things. The third — your criminal record — is permanent unless you take specific legal action, and even then it is not truly erased. Mixing these up is one of the most common misunderstandings we see, so let's keep them separate.
The three records a DUI affects
Before getting into timelines, it helps to name the three records clearly, because they are governed by different agencies and different laws:
The two 10-year clocks
- Priorability — how long a prior DUI can be used to enhance penalties on a NEW DUI (sentencing law)
- DMV driving record — how long the conviction is reported on your California driver record (DMV / Vehicle Code)
The permanent record
- Criminal record — the conviction itself, held by the courts and the California Department of Justice
- Does not expire on its own — stays unless reduced or dismissed, and even a dismissal does not erase it
All three can be triggered by a single arrest, which is why a DUI feels like it follows you in more than one way. If you are still early in the process, our overview of what happens after a DUI arrest walks through how the court case and the DMV side run on parallel tracks.
1. The 10-year "priorable" window
In California, a DUI is what's called a "priorable" offense for 10 years. That means if you pick up a new DUI within 10 years of an earlier one, the earlier conviction counts as a prior and pushes the new charge into the enhanced-penalty tier — a second, third, or fourth offense, each carrying tougher mandatory consequences.
How is the 10 years measured? Under California Vehicle Code § 23540, the enhancement applies when the new "offense occurred within 10 years of a separate violation" that resulted in a conviction. In other words, the clock runs from the date of the prior violation to the date of the new violation — not from conviction date to conviction date, and not from arrest to arrest in the colloquial sense. The prior does have to have resulted in a conviction (or an equivalent, like a wet reckless, which California still counts as a prior) to trigger the enhancement.
Why the start date matters
Because the priorable window runs violation-date to violation-date, two cases that are technically more than 10 years apart by arrest date can fall just inside or just outside the window. If your earlier DUI is close to the 10-year mark, the exact dates can be the difference between a first-offense and a second-offense filing. This is fact-specific and worth reviewing with an attorney.
After 10 years with no new DUI, the older conviction generally "washes out" for enhancement purposes — a fresh DUI would usually be charged as a first offense again. But "washout" only addresses priorability. It does not remove the DUI from your DMV record or your criminal record, which is where people often get tripped up. For how the enhancement tiers actually play out, see our page on California DUI penalties.
2. The DMV driving record — 10 years
Separately, a DUI conviction is reported on your California DMV driving record for 10 years. According to the California DMV, DUI (alcohol-related) convictions are retained and reported on a noncommercial public driver record for 10 years — a reporting period that took effect January 1, 2007. This is the record insurance companies, employers running a DMV check, and law enforcement can see.
Commercial drivers: much longer
If you hold a commercial driver license (CDL), the math is very different. A major violation like DUI committed in a commercial vehicle is generally retained on the CDL record far longer than 10 years. If your livelihood depends on a CDL, treat a DUI as a career-level issue and get advice quickly.
Two important points. First, the DMV's 10-year reporting clock is separate from the priorability clock above — they happen to both be 10 years, but they answer different questions. Second, the DMV's administrative action against your license (the suspension side) runs on its own track and its own deadlines, including the famous 10-day window to request a DMV hearing after a DUI arrest. The driver-record retention period is not the same thing as how long your license is suspended — for that, see DUI license suspension.
3. The criminal record — permanent unless you act
This is the one that surprises people most. Your criminal record does not expire. Unlike the two 10-year clocks, a DUI conviction stays on your criminal history indefinitely — it does not automatically fall off after 10 years. It can keep appearing on background checks run by employers, licensing boards, and government agencies unless you take affirmative steps to address it.
The main tool people reach for is California's Penal Code § 1203.4, often loosely called "expungement." It is important to be precise about what it does and does not do.
What PC 1203.4 actually does — and doesn't
Under PC § 1203.4, if you successfully complete probation (or the court grants relief in its discretion), you can withdraw your plea, the court enters a not-guilty plea, and the case is dismissed. On a background check, the entry typically shows the conviction was dismissed — which is meaningful and can help with employment. But it is not a true erasure.
What a 1203.4 dismissal can do
- Set aside the plea and dismiss the case
- Let you tell most private employers the case was dismissed
- Improve how the record reads on many background checks
What it does NOT do
- Erase or seal the record — the conviction still exists
- Remove the 10-year priorability — a dismissed DUI still counts as a prior on a future DUI
- Remove it from your DMV driving record
- Restore everything — e.g., it does not by itself restore firearm rights, and the prior can still be "pleaded and proved" in a later case
The statute itself spells out the catch: even after a 1203.4 dismissal, "in any subsequent prosecution of the defendant for any other offense, the prior conviction may be pleaded and proved and shall have the same effect as if probation had not been granted." So a dismissed DUI still counts as a prior inside that 10-year priorability window, and the DMV keeps its own record regardless of the court's dismissal. A separate reduction of a felony to a misdemeanor (under Penal Code § 17(b), where eligible) is a different tool with different effects.
"Expungement" is the wrong mental model
In many states, expungement means the record is destroyed or sealed. California's PC 1203.4 is better thought of as a court-ordered dismissal that updates how the record reads — not a delete button. Knowing this up front prevents a lot of false expectations.
How to limit the long-term impact
Because the strongest, most permanent record is the criminal one, the best time to influence all three timelines is before a conviction is entered. A charge that is reduced or dismissed at the outset never becomes a 10-year prior, never lands on the DMV record as a DUI conviction, and never needs a later 1203.4. That is why early defense work matters — challenging the stop, the field sobriety tests, the breath or blood evidence, and the procedure. Our overview of common DUI defenses explains the angles.
If you already have a conviction, options like a PC 1203.4 dismissal (and, where eligible, a felony-to-misdemeanor reduction) can still meaningfully improve how your record reads going forward, even though they will not turn back the priorability or DMV clocks. Which options fit depends on your exact charge, plea, and probation outcome — this is a good thing to review case-by-case with a DUI defense attorney.
