About the author →

Los Angeles is the nation's second-largest city and a major DUI enforcement zone. LAPD patrols the streets and conducts saturation patrols and checkpoints—especially in entertainment-heavy areas like Hollywood, Downtown LA, and around nightlife corridors—while the California Highway Patrol dominates freeway arrests across LA County. The result: a high volume of DUI arrests funneled through a single courthouse with a well-staffed prosecutors' office and predictable (though aggressive) enforcement patterns that shape your defense strategy.

How DUIs are policed in Los Angeles

The Los Angeles Police Department (LAPD) enforces DUI laws throughout the City of Los Angeles, with one of the nation's largest municipal police forces and a history of aggressive DUI checkpoint and saturation patrol operations. (DRAFT — verify current LAPD staffing and checkpoint frequency) LAPD patrols are concentrated around downtown, Hollywood, and neighborhoods with active nightlife; officers are especially vigilant after bars and clubs close. The California Highway Patrol (CHP) handles freeway corridors, including Interstate 5, I-10, I-405, and US-101, and produces the highest number of DUI arrests in the LA area. (DRAFT — verify CHP division assignment and freeway coverage)

Who prosecutes a Los Angeles DUI—and where

This is the critical distinction that sets Los Angeles apart from many other LA County cities. Misdemeanor DUI cases in the City of Los Angeles are prosecuted by the Los Angeles City Attorney's Office, not the LA County District Attorney. (DRAFT — verify city attorney misdemeanor jurisdiction) The City Attorney's Criminal Branch includes a dedicated Driving Under the Influence of Drugs (DUID) Unit, which received over $1.3 million in OTS grant funding to prosecute impaired-driving cases through September 2026. The office reported filing approximately 99% of DUI cases referred by law enforcement over the past two years. (DRAFT — verify 99% filing rate and grant continuity) All felony DUIs are prosecuted by the LA County District Attorney, regardless of location within the city.

Venue: The Metropolitan Courthouse (Metro Court) at 1945 South Hill Street, downtown Los Angeles, handles the vast majority of Los Angeles misdemeanor DUI cases. (DRAFT — verify courthouse address and current division assignments) The Metro Court's Central Division covers downtown, Chinatown, the Arts District, Hollywood, Los Feliz, Mid-City, and surrounding neighborhoods—which explains why it has the largest caseload of misdemeanor DUI prosecutions in the county. Departments 71–75 are dedicated DUI pre-trial courtrooms. The court operates Monday–Friday, 8 a.m.–4:30 p.m. (DRAFT — verify operating hours)

Who prosecutes my Los Angeles DUI—the City Attorney or the DA?
Misdemeanor DUI cases in the City of Los Angeles are prosecuted by the Los Angeles City Attorney's Criminal Branch. The office has a dedicated DUID Unit and prosecutes roughly 99% of cases referred by law enforcement. Felony DUIs go to the LA County District Attorney. This split—city attorney for misdemeanor, DA for felony—is unique to LA city and differs from many neighboring cities that are prosecuted entirely by the County DA.
Where will my Los Angeles DUI case be heard?
Misdemeanor DUI cases are heard at the Metropolitan Courthouse (Metro Court), located at 1945 South Hill Street, downtown Los Angeles. The court has dedicated DUI departments (71–75) and handles more misdemeanor DUI cases than any other courthouse in LA County. Felony DUIs are filed at the Clara Foltz Criminal Justice Center (also downtown) and eventually transferred to the appropriate felony division.
Why does Los Angeles have so many DUI arrests?
Los Angeles's high DUI arrest volume reflects three factors: (1) the sheer size of the city and LAPD jurisdiction; (2) concentration of bars, clubs, and nightlife in Hollywood, Downtown LA, West Hollywood, and Venice—areas LAPD targets with checkpoints and saturation patrols; and (3) major freeway corridors (I-5, I-10, I-405, US-101) where the California Highway Patrol conducts intensive DUI enforcement. Entertainment and nightlife districts account for the highest arrest rates.
What role does the California Highway Patrol play in LA DUI arrests?
The CHP has jurisdiction over all California freeways, including major LA County corridors (I-5, I-10, I-405, US-101). The CHP produces the highest number of DUI arrests in the Los Angeles area, especially during nights and weekends. CHP officers patrol with extra vigilance for erratic or swerving drivers and are equipped with dashcam evidence. Misdemeanor cases from CHP freeway arrests may still be prosecuted by the LA City Attorney if the arrest occurred within city limits, or by the County DA if in unincorporated areas.
Does Ron Chini have an office in Los Angeles?
No. Ron Chini is based in Irvine, California, and defends DUI cases throughout Los Angeles County—including the City of Los Angeles—from his Irvine office. He does not maintain a local office in LA. Ron is an experienced DUI defense attorney; he does not claim to be a certified specialist, and no result is ever guaranteed.
