About the author →

San Fernando is one of Los Angeles County's smallest cities — roughly two and a half square miles, completely surrounded by the City of Los Angeles, with Sylmar to the north, Lake View Terrace to the east, Pacoima to the south, and Mission Hills to the west. That geography matters more than most drivers realize: because San Fernando is its own city and not part of Los Angeles, a DUI arrested here follows a different prosecution path than one arrested a few blocks away in an L.A. neighborhood. Understanding that difference early is one of the most useful things you can do for your case.

How DUIs are policed in San Fernando

Unlike the surrounding L.A. neighborhoods — which are patrolled by the LAPD — the City of San Fernando keeps its own San Fernando Police Department. Its officers patrol the compact street grid around San Fernando Road, Maclay Avenue, Truman Street, and the Sylmar/San Fernando Metrolink corridor, and they make most of the city's DUI stops. San Fernando PD runs its own DUI enforcement program, including DUI sobriety and driver's-license checkpoints and roving saturation patrols on weekend and holiday nights. The department publicly announces these operations, and its press releases note that funding comes from a grant through the California Office of Traffic Safety (OTS) and the National Highway Traffic Safety Administration (NHTSA). At a checkpoint, officers stop vehicles in a pattern, look for signs of impairment, and divert drivers they suspect into a secondary screening with field sobriety and breath tests.

As a small city tucked inside a dense part of the Valley, San Fernando does not carry the raw collision volume of a large city, but OTS still tracks alcohol-involved crashes here and the OTS grant funding is what keeps the local checkpoint program running. (DRAFT — verify the city's current OTS profile at ots.ca.gov; do not cite any specific rank, count, or grant figure without confirming it.) Many San Fernando DUI arrests also begin on the freeways that ring the city — the 210, the 5, and the 118 are all close by. Those freeways fall under the California Highway Patrol, so a CHP officer, rather than San Fernando PD, may be the arresting agency if your stop happened on the freeway. (DRAFT — confirm which CHP area office covers the specific freeway segment of the arrest; the surrounding stretches are split among more than one Southern Division office.)

• Arresting agency is usually the San Fernando Police Department on city streets — or the CHP if you were stopped on the 210, 5, or 118.
• San Fernando PD runs its own OTS/NHTSA grant-funded DUI checkpoints and saturation patrols, mostly on weekend and holiday nights.
• Checkpoint refusals, breath/blood results, and field-sobriety observations are all common pressure points a defense attorney examines.
• Where you were arrested — inside the City of San Fernando vs. a neighboring L.A. neighborhood — affects who prosecutes the case.

Who prosecutes a San Fernando DUI — and where

Here is the distinction that trips people up. In the City of Los Angeles, misdemeanor DUIs are prosecuted by the Los Angeles City Attorney. But San Fernando is not part of the City of Los Angeles — it is a separate, independent city. As a result, a misdemeanor DUI committed inside the City of San Fernando is generally prosecuted by the Los Angeles County District Attorney's Office, not the L.A. City Attorney. Any felony DUI — for example, a DUI causing injury or a fourth offense — is always handled by the L.A. County District Attorney as well. (DRAFT — confirm current prosecuting-agency assignment for City-of-San-Fernando misdemeanor DUI filings; the City of San Fernando's general legal counsel is a contracted firm, but criminal DUI filing authority is the key item to verify with the courthouse.)

A San Fernando DUI is heard at the San Fernando Courthouse (the Superior Court's North Valley District), which serves the northeast San Fernando Valley — Sylmar, Pacoima, Mission Hills, Granada Hills, and the City of San Fernando itself. This courthouse is not one of the L.A. courthouses with its own dedicated page on this site, so we link the county hub below rather than a courthouse page. A misdemeanor DUI typically starts with an arraignment, then moves to a trial department if you plead not guilty. (DRAFT — confirm current DUI calendaring and department routing at the San Fernando Courthouse before relying on specifics.)
