Monterey Park is a city with its own police department, its own enforcement priorities, and a courthouse routing that surprises a lot of drivers. Understanding who investigates your case, who files the charges, and where you will appear is the first step toward defending it. Here is how a Monterey Park DUI actually moves through the system — and how Ron Chini approaches it.
How DUIs are policed in Monterey Park
Most DUI arrests on Monterey Park's surface streets are made by the Monterey Park Police Department, the city's own municipal agency — not a contract sheriff's station. Monterey Park PD runs an ongoing DUI enforcement and education program that includes sobriety/driver's-license checkpoints and roving DUI saturation patrols, where officers watch for impaired-driving cues along corridors like Atlantic Boulevard and Garvey Avenue. The department publicly announces many of these operations in advance and notes that funding comes from a grant through the California Office of Traffic Safety (OTS) and the National Highway Traffic Safety Administration. The department also reminds drivers that impairment from prescription medication, over-the-counter drugs, and cannabis can lead to a DUI arrest just as alcohol can.
Monterey Park participates in the statewide OTS grant-funded enforcement framework like many San Gabriel Valley cities, so checkpoints and patrols tend to cluster around holidays and weekends (DRAFT — verify Monterey Park's current OTS profile and any specific figures at ots.ca.gov before relying on numbers; this page intentionally states no rank, arrest count, or grant amount). On the freeways, the picture is different: the California Highway Patrol's East Los Angeles Area office, which is itself headquartered in Monterey Park, patrols the I-10 (San Bernardino Freeway) and SR-60 (Pomona Freeway) that run through and past the city. A DUI stop made by CHP on one of those freeways is investigated by CHP, but it is still filed and heard locally (DRAFT — confirm the CHP area office and freeway coverage).
- Arresting agency on city streets: Monterey Park Police Department (its own municipal force).
- Freeway stops (I-10 / SR-60): California Highway Patrol, East Los Angeles Area office (located in Monterey Park).
- Enforcement style: announced DUI checkpoints plus roving saturation patrols, OTS/NHTSA grant-funded.
- Common arrest corridors: Atlantic Boulevard, Garvey Avenue, and the I-10 and SR-60 freeways.
Who prosecutes a Monterey Park DUI — and where
Monterey Park's City Attorney serves as the city's prosecutor for Municipal Code violations only. A DUI is charged under the California Vehicle Code, not the city code, so a Monterey Park DUI is prosecuted by the Los Angeles County District Attorney's Office — both the standard misdemeanor (Vehicle Code §§ 23152(a)/(b)) and any felony DUI. Monterey Park does not have its own criminal-DUI prosecutor the way larger cities such as Los Angeles, Pasadena, or Long Beach do (DRAFT — confirm current prosecuting authority with the LA County DA and the Monterey Park City Attorney; verify there is no city-prosecutor handoff for any DUI-adjacent charges).
For the courthouse, Monterey Park sits in the Superior Court's Northeast District, and DUI cases are generally heard at the Alhambra Courthouse on West Commonwealth Avenue in Alhambra — the branch that serves Alhambra, Monterey Park, San Gabriel, and Temple City. The Alhambra Courthouse is not one of the dedicated courthouse guides on this site, so we do not link a courthouse page for it; for a broader overview of how Los Angeles County DUI cases are handled, see the county hub below. Always confirm your assigned courtroom and date from your own paperwork or the court — case routing can change (DRAFT — verify Monterey Park DUI filings currently route to the Alhambra Courthouse, Northeast District).
Who prosecutes a DUI in Monterey Park?

A DUI is a California Vehicle Code charge, and Monterey Park's City Attorney prosecutes only Municipal Code violations — the city does not have its own criminal-DUI prosecutor. Felony DUI is always handled by the LA County DA. (DRAFT — verify with the LA County DA and the Monterey Park City Attorney.)
Which courthouse handles a Monterey Park DUI?
Monterey Park is in the Superior Court's Northeast District, and DUI cases are generally heard at the Alhambra Courthouse in Alhambra, which serves Alhambra, Monterey Park, San Gabriel, and Temple City. Confirm your exact courtroom and appearance date from your citation or the court, since routing can change. (DRAFT — verify current routing.)
Does Monterey Park run DUI checkpoints?
Yes. The Monterey Park Police Department conducts DUI/driver's-license checkpoints and roving saturation patrols as part of an ongoing, grant-funded enforcement program, and it often announces these operations in advance. On the I-10 and SR-60 freeways near the city, DUI stops are typically made by the CHP East Los Angeles Area office, which is based in Monterey Park.
I was just arrested in Monterey Park — what should I do first?
Act on the DMV deadline immediately: you generally have only 10 days from a California DUI arrest to request a DMV hearing, or your license is set to suspend automatically. That clock runs separately from your court case. Then gather your paperwork and call for a free consultation so a defense can start before key deadlines pass. See how the DMV hearing works.
