California’s most recent official DUI dataset (DMV, 32nd DUI-MIS report) shows 110,017 DUI arrests in 2021, up 14.7% from 2020’s pandemic low but far below the 180,212 recorded in 2011. About two-thirds of arrests end in DUI conviction (66.6% for 2020 arrests). Nationally, 12,429 people died in alcohol-impaired crashes in 2023 (NHTSA).
If you search for California DUI statistics, you’ll find plenty of pages quoting numbers with no year and no source. This page does the opposite. Every figure below carries its reporting year and its source, the two things that make a statistic usable, and where a commonly searched number does not exist in any authoritative dataset, we say so instead of inventing it. As of September 2026, the latest complete statewide dataset is the DMV’s 32nd Annual DUI-MIS report (published 2025, covering data through 2021), supplemented by NHTSA’s 2023 national and state estimates. Here is what the verified data actually shows.

Note the different definitions in the fatality rows; the “Why These Numbers Are Hard to Compare” section explains them.
California recorded 110,017 DUI arrests in 2021, according to the DMV’s 32nd DUI-MIS report, the most recent year with complete official data. The decade view:
| Year | DUI Arrests | Year-over-Year Change (calculated) | Source |
| 2011 | 180,212 | — | DMV DUI-MIS |
| 2012 | 172,893 | -4.1% | DMV DUI-MIS |
| 2013 | 160,388 | -7.2% | DMV DUI-MIS |
| 2014 | 154,743 | -3.5% | DMV DUI-MIS |
| 2015 | 141,372 | -8.6% | DMV DUI-MIS |
| 2016 | 130,054 | -8.0% | DMV DUI-MIS |
| 2017 | 123,548 | -5.0% | DMV DUI-MIS |
| 2018 | 127,437 | +3.1% | DMV DUI-MIS |
| 2019 | 124,141 | -2.6% | DMV DUI-MIS |
| 2020 | 95,957 | -22.7% | DMV DUI-MIS |
| 2021 | 110,017 | +14.7% | DMV DUI-MIS |
The long arc is downward: arrests fell roughly 39% from 2011 to 2021, and the arrest rate per 100,000 licensed drivers fell from 752 to 401 over the same period. The 2020 collapse tracks pandemic-era driving and enforcement disruptions, and 2021’s rebound recovered only part of it. The DMV’s data comes from Department of Justice arrest records and court-reported dispositions; it counts arrests, not unique drivers, and later years’ totals can be revised slightly between report editions.
On average, about 301 DUI arrests per day, calculated from the DMV’s 110,017 arrests in 2021 divided by 365 days. This is an annual average, not a daily count: arrests cluster heavily around weekends, holidays, and enforcement periods, so actual daily figures swing well above and below the average. (Calculation: 110,017 ÷ 365 = 301.4. Calculated from DMV DUI-MIS data; not a figure the DMV reports directly.)
The most recent reliable national estimate is just over one million DUI arrests in 2019, per the FBI’s Crime in the U.S. program (estimated at 1,024,508). Two important caveats: the figure covers “driving under the influence” as reported by participating agencies, and the FBI’s transition from the legacy summary system to NIBRS after 2020 left national arrest totals less complete for several years, which is why this article does not quote a newer national arrest count as authoritative. Comparing this national arrest figure with California’s DMV numbers is only roughly valid, since the datasets use different collection methods and reporting periods.
| Period | What the verified data shows |
| 2011-2017 | Steady decline in arrests, from 180,212 to 123,548, with the arrest rate per 100k licensed drivers falling every year |
| 2018-2019 | Plateau near 124,000-127,000 arrests |
| 2020 | Pandemic collapse: -22.7% to 95,957 |
| 2021 | Partial rebound: +14.7% to 110,017; 78% of counties saw increases |
| Fatalities | Moving the opposite direction: alcohol-involved crash deaths rose to 1,344 in 2021, the highest in at least a decade (DMV/CHP) |
The uncomfortable pairing in this table is the story: fewer arrests, more alcohol-involved deaths. The DMV report documents both without asserting a single cause, and neither will we; enforcement levels, driving patterns, and post-pandemic behavior all changed in the same window, and the data does not isolate their contributions. What the report does state directly: drug-involved crash fatalities have more than tripled since 1995 (867 in 2021), while 2021 alcohol-involved deaths sit at roughly their 1995 level.
Three different measures get blended in most articles; they should not be:
The DMV report also notes that in 2020, fewer than half (44.2%) of drivers in alcohol- and drug-involved fatal crashes had no prior DUI-related record, a data point that shows up later in how prosecutors treat repeat offenses.
California does not publish a single statewide “DUI with injury conviction” count, and no authoritative source reports a “DUI-with-injury conviction rate.” What the verified data does show: a share of DUI arrests each year are associated with injury or fatal crashes (the DMV report tracks alcohol- and drug-involved drivers in fatal/injury crashes as its own dataset), and injury allegations are the main gateway from misdemeanor DUI to felony charging under Vehicle Code 23153. For readers researching this after an injury arrest: the statistic you actually need is not statewide, it’s your county’s charging practice, which no public dataset captures; the legal elements section below explains what prosecutors must prove.
California recorded 4,844 felony DUI arrests in 2021, about 4.4% of all DUI arrests, a share essentially unchanged from 2020 (DMV, 32nd DUI-MIS report). The overwhelming majority of DUI arrests, 105,173 in 2021, were misdemeanors.
Why so few felonies? Because under California law, a standard DUI, even a repeat one, is a misdemeanor. A DUI becomes a felony in specific circumstances: injury to another person under VC 23153 (chargeable as a felony depending on the facts, not automatically), a fourth or subsequent DUI within 10 years (VC 23550), or any DUI after a prior felony DUI conviction (VC 23550.5). Statewide felony DUI conviction totals are not published as a separate annual figure, so beware of pages quoting one; the arrest-side share is the verifiable number.
The keyword data shows people searching for “elements of DUI with injury prosecution,” so here is the legal answer, clearly separated from statistics. Under Vehicle Code 23153, a DUI-with-injury conviction requires proof beyond a reasonable doubt that the driver: (1) drove under the influence of alcohol or drugs, or with a BAC of 0.08% or higher; (2) while driving, also committed an illegal act or neglected a legal duty (such as a traffic violation or negligence); and (3) that act or neglect proximately caused bodily injury to another person.
Element (2) is what most people miss: being impaired and involved in an injury crash is not enough by itself; the prosecution must tie the injury to a specific unlawful act or negligent omission. No agency publishes prosecution success rates for these cases, and any site claiming a specific “conviction rate for DUI with injury” is not drawing on published data.
Two different questions hide inside “which county has the highest DUI rate,” and they have different answers:
Raw arrest counts (2021, DMV): Los Angeles County alone accounted for 17.8% of all California DUI arrests, and five counties (Los Angeles, Orange, Riverside, San Bernardino, and San Diego) each recorded over 6,000 arrests, together making up 46.5% of the state total. That reflects population, not risk.
Arrest rates (2021, DMV, per 100 licensed drivers): county rates ranged from 0.2 to 1.8 against a statewide average of 0.4, and eleven counties, generally smaller ones, exceeded twice the statewide average. Meanwhile eight counties came in below average: Contra Costa (0.3), Los Angeles (0.3), Plumas (0.2), Sacramento (0.3), San Francisco (0.2), San Mateo (0.3), Santa Clara (0.2), and Yolo (0.3).
So the counties with the most arrests are not the counties with the highest rates; big-metro counties dominate the totals while several rural counties lead per-driver. A definitive “highest DUI rate by county” ranking also depends on the denominator chosen (licensed drivers vs. residents vs. traffic volume), which is why this article reports the DMV’s own rate figures rather than constructing a new ranking. County-level detail lives in Table 2 of the DMV’s report and its online DUI-MIS dashboards.
From the DMV’s 2021 arrest data: the median age of a DUI arrestee was 32. Nearly half (46.3%) of arrestees were 30 or younger and almost three-quarters (73.0%) were 40 or younger. Juveniles under 18 were 0.3% of arrests, and drivers over 60 were 4.3%. The under-21 share has declined meaningfully, from 7.8% of arrests in 2011 to 5.3% in 2021, a 32% relative drop that coincides with, though is not proven to be caused by, zero-tolerance rules for young drivers and changing driving habits.
Males accounted for 77.8% of California DUI arrests in 2021 (DMV). The long-term shift is notable: the female share of DUI arrests has roughly doubled since this reporting series began, from 10.6% in 1989 to 22.2% in 2021. These are arrest figures, not conviction figures, and the DMV notes the year-to-year proportions are relatively stable.
An arrest is not a charge, and a charge is not a conviction, and California’s own data quantifies the gap. Tracking what happened to drivers arrested each year (DMV, by arrest cohort):
| Arrest year | DUI convictions | Conviction rate | Convicted of alcohol/drug reckless instead |
| 2017 | 93,606 | 72.9% | ~8% |
| 2018 | 93,926 | 71.1% | ~8% |
| 2019 | 88,043 | 68.9% | ~8% |
| 2020 | 68,582 | 66.6% (lowest recorded) | ~8% |
Read this table carefully and three facts emerge. About a third of DUI arrests do not end in a DUI conviction. Roughly 8 in 100 arrestees are convicted of alcohol- or drug-related reckless driving instead, the “wet reckless” reduction. And the conviction rate has drifted downward for a decade, from the low 70s to 66.6% for the 2020 cohort. The remainder includes dismissals, acquittals, reductions to other charges, and cases never filed; the DMV does not break these out into a single public figure. This is also why no honest source can tell you “X% of arrests get dismissed.”
Statistics describe the system; consequences land on individuals. A DUI arrest in California starts two proceedings, criminal court and a DMV license action with a 10-day hearing deadline, and a first conviction typically brings probation, fines and assessments, a DUI program, and license consequences, with an ignition interlock path for restricted driving. Penalties escalate sharply for repeat offenses within 10 years, and injury cases carry felony exposure. The two-thirds conviction rate above is not a promise in either direction; it reflects thousands of cases where the evidence was tested, negotiated, or not. Our guides to what happens after a first-time DUI, second DUI penalties, and the DMV hearing cover the consequences side in depth.
A few legal structures shape the numbers you’ve just read. The 0.08% per se standard (VC 23152(b)) defines most arrests; the separate drug-DUI provisions feed the growing drug-involved category; the 10-year lookback and escalating repeat-offense penalties influence charging and plea patterns; the wet reckless statute (VC 23103.5) creates the ~8% reduced-conviction category the DMV tracks; and felony thresholds (VC 23153, 23550, 23550.5) explain why only about 4.4% of arrests are felonies. The DMV’s administrative license system runs parallel to all of it, which is why arrest counts and license actions are separate datasets. None of this proves that any single law caused any single trend, and the DMV report itself avoids such claims; laws set the categories the data flows into.
Five distinctions prevent most bad conclusions:
Verified data ends in 2021 (DMV) and 2023 (NHTSA); what follows is trend context, clearly separated from data. The trends worth watching in 2026: whether arrest volumes continue recovering toward pre-pandemic levels as the next DUI-MIS editions publish; whether the divergence between falling arrests and elevated impaired-driving deaths persists; the continued rise of drug-involved and polysubstance cases, which already tripled since 1995 in the fatality data; expanded ignition-interlock use following the extension of California’s IID program through 2033; and enforcement technology developments, from grant-funded DUI patrols to the federal push on impaired-driving prevention technology in new vehicles. When 2022-2024 DMV data publishes, this page should be updated; the DMV’s DUI-MIS dashboards are the fastest-updating official source in the meantime.
The numbers above describe more than a hundred thousand cases a year, each of which turned on its own facts.
