The Rancho Cucamonga courthouse for Fontana DUI cases
Fontana DUI cases are typically filed at the San Bernardino County Superior Court Rancho Cucamonga Courthouse, also known as the Rancho Cucamonga Justice Center, located at 8303 N. Haven Avenue in Rancho Cucamonga. This west-end SB County courthouse serves Fontana, Rancho Cucamonga, Ontario, Upland, Montclair, and surrounding west county cities. It is one of the busier courthouses in the SB County system given the population density of the western Inland Empire. Some Fontana arrests on I-10 may be filed at the San Bernardino main courthouse depending on the CHP division that made the arrest.

The DMV Driver Safety Office for Fontana
The San Bernardino Driver Safety Office handles APS hearings for western San Bernardino County, including Fontana. The 10-day deadline to request the APS hearing runs from the arrest date. For Fontana arrests, confirm the specific DSO from the pink Notice of Suspension, as the SB County DSO may route Fontana cases based on the specific arrest location and arresting agency. Missing the deadline results in automatic suspension beginning day 31 after arrest.
You have 10 calendar days from your arrest date to request an APS hearing. Missing this deadline means automatic license suspension beginning 30 days after arrest. Check your pink Notice of Suspension for the correct Driver Safety Office, or have an attorney request the hearing on your behalf.
SB County Sheriff, Fontana Station, and CHP enforcement
The San Bernardino County Sheriff Department's Fontana Station is the primary law enforcement agency for the city of Fontana, which is served by the Sheriff under a contract arrangement. The Sheriff's Department conducts DUI enforcement throughout the city. The California Highway Patrol has a major presence on I-10 (the San Bernardino Freeway) and I-210 (the Foothill Freeway), both of which run through Fontana and carry some of the highest vehicle volumes in the Inland Empire. The I-10/I-15 interchange near Fontana/Ontario is a major CHP enforcement location. NASCAR's Toyota Speedway in Fontana generates additional DUI enforcement during major events.
SB County prosecution for Fontana cases
Fontana DUI cases are prosecuted by the San Bernardino County DA's West Valley Branch operating out of the Rancho Cucamonga Courthouse. The same county-wide charging guidelines apply. SB County's firm prosecution posture applies equally in the west-county Rancho Cucamonga courthouse. Defense counsel with experience in the Rancho Cucamonga courthouse is valuable for Fontana defendants given the local prosecutorial and judicial practices in that specific courthouse.
After a Fontana DUI arrest
Request the DMV APS hearing within 10 days at the San Bernardino Driver Safety Office. Your arraignment will be scheduled at the Rancho Cucamonga Courthouse at 8303 N. Haven Avenue. Retain California DUI counsel before arraignment. Fontana Sheriff arrests will have documentation patterns different from CHP freeway arrests, and I-10/I-210 CHP arrests are often accompanied by dashcam video — both affect defense strategy in distinct ways.
