About the author →
Fontana's DUI enforcement environment is shaped by three critical factors: its position at the intersection of three major freeways (I-10, I-15, and SR-210) that cut through the city, its identity as a regional logistics and trucking hub, and its own active police department. The I-10 corridor carries heavy east-west traffic linking Los Angeles to the High Desert; I-15 runs north-south from San Diego to Las Vegas; and SR-210 connects the San Gabriel Valley to the High Desert. These three arterials create constant freight and commuter flow—and with that flow comes California Highway Patrol DUI enforcement on the freeways. Within the city, the Fontana Police Department runs its own checkpoints and patrols, particularly in commercial corridors, near the Auto Club Speedway, and on major arterials like Slover Avenue and Sierra Avenue. Together, freeway and local enforcement make Fontana one of San Bernardino County's more active DUI-arrest zones.
How DUIs are policed in Fontana
Fontana operates its own Fontana Police Department and conducts regular DUI checkpoints and saturation-patrol operations, funded partly by grants from the California Office of Traffic Safety. The city also sees significant California Highway Patrol enforcement on the I-10, I-15, and SR-210 corridors that run through Fontana.
OTS Ranking: According to California's Office of Traffic Safety rankings, Fontana's DUI arrest and collision victim counts reflect both legitimate impaired-driving incidents and the intensity of freeway enforcement on the I-10 and I-15 corridors. As one of San Bernardino County's largest cities and a major transportation hub, Fontana experiences significant DUI checkpoint and patrol activity.
Fontana Police Department Checkpoints: The Fontana Police Department conducts regular DUI and driver's license checkpoints throughout the city, typically operating from evening hours through early morning on Friday and Saturday nights. Checkpoint locations are selected based on historical DUI arrest and collision data and are pre-announced via press releases. The department also conducts saturation patrols in high-incident areas, particularly near commercial districts, transportation corridors, and areas surrounding the Auto Club Speedway during racing events.
CHP Inland Division: The California Highway Patrol's Inland Division (headquartered at 847 E. Brier Drive, San Bernardino, CA 92408) patrols the I-10, I-15, and SR-210 corridors throughout San Bernardino County, including Fontana. These freeways are among California's busiest freight and commuter routes, and the CHP conducts both routine traffic enforcement and special DUI-operation units (DUOs) on these corridors, particularly overnight and on weekends. Any DUI arrest on the freeway route through Fontana is handled by the CHP and prosecuted at the appropriate San Bernardino County courthouse.
Where a Fontana DUI case is heard
Fontana DUI cases are not heard inside Fontana. The court's own guidance for the Fontana District confirms it schedules only traffic infractions and does not hear felony or misdemeanor cases, so a DUI filed out of Fontana is calendared at the Rancho Cucamonga Courthouse instead. The San Bernardino County District Attorney's Office prosecutes the case, not a Fontana city attorney. That West Valley courthouse also handles DUI filings from Rialto, Ontario, Upland, and Rancho Cucamonga itself, so your case shares a calendar with the rest of the region. Whether CHP wrote your report on I-10, I-15, or SR-210, or Fontana PD wrote it on a city street, the case lands at the same building either way. Ron appears at every hearing and coordinates the court calendar with your separate ten day DMV deadline.
Booking and getting your car back after a Fontana arrest
Fontana Police Department officers do not hold people locally beyond initial processing. The Sheriff's West Valley Detention Center in Rancho Cucamonga handles remote video court appearances for people arrested out of Fontana, according to the Sheriff's Department's own description of that facility, so most Fontana arrestees move through it rather than a jail inside city limits. A CHP stop on I-10, I-15, or SR-210 near Fontana typically routes to the same facility. Getting your car back is a separate process from your custody status. Fontana's published towing and release policy allows release during regular business hours once the registered owner, or an agent acting for them, shows a valid driver's license and current registration and the underlying reason for impound, such as a suspended license, has been resolved. The department also keeps a 24 hour phone line that can tell you which storage yard is holding the vehicle before you drive out to get it.
Fontana transit and DMV options during a suspension
Fontana sits on Omnitrans' bus network, with routes reaching the Fontana Transit Center and connecting onward to Rialto, San Bernardino, Rancho Cucamonga, and Ontario. Omnitrans is also building the West Valley Connector, a rapid bus corridor under construction that is meant to link Pomona, Montclair, Ontario, Rancho Cucamonga, and Fontana with faster, more frequent service once it opens. Metrolink's San Bernardino Line stops in Fontana too, at the station on Orange Way, with direct service toward Los Angeles Union Station and the rest of the West Valley. For DMV business apart from the ten day Driver Safety hearing, such as reinstating a license once a suspension period ends, Fontana has its own DMV office on Poplar Avenue, though it is set up mainly for drive tests, records, and document requests rather than full counter transactions, so a more involved reinstatement may still require a different office.
