The court process for Ontario DUI cases
Ontario DUI cases are filed with the San Bernardino County Superior Court. Cases from the county's western end are heard at the Rancho Cucamonga Courthouse at 8303 Haven Avenue rather than at the courthouse in the City of San Bernardino. Ontario is in San Bernardino County, so cases are prosecuted by the San Bernardino County District Attorney's Office under the same county-wide charging and offer policies that apply across the county.

The DMV 10-day hearing deadline
The DMV handles the suspension of your driving privilege through an Administrative Per Se action that runs entirely separate from the criminal case. Under California Vehicle Code Section 13558 you have ten calendar days from the arrest date to request the hearing, or the license is suspended automatically. Most hearings are now held by phone or video, and in most cases your attorney appears for you.
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. Request the hearing through the DMV Driver Safety unit, or have an attorney request it on your behalf, to preserve your driving privilege while the case is pending.
Ontario Police and CHP DUI enforcement
The Ontario Police Department patrols downtown Ontario, the Ontario Mills and Ontario Ranch areas, and the hotel and entertainment districts near Ontario International Airport, with weekend and holiday DUI operations. The California Highway Patrol covers a dense web of freeways through the city, Interstate 10, State Route 60, and Interstate 15, one of the busiest freight and commuter crossroads in the Inland Empire.
How San Bernardino County prosecutes DUI cases
The San Bernardino County District Attorney's Office prosecutes Ontario DUI cases. A typical first offense with no aggravating facts resolves with three years of summary (informal) probation, a first-offender DUI program, fines and assessments that commonly total $2,000 to $3,500, and a license suspension. Where the stop, the investigation, or the chemical test has a real weakness, a reduction to a wet reckless under Vehicle Code Section 23103.5, or in some cases a dismissal, becomes realistic. Aggravating facts such as a high BAC, a refusal, an accident, or a prior conviction raise the exposure and change the strategy.
What to do after a Ontario DUI arrest
Request the DMV hearing within ten days. Find your arraignment date and courthouse on the citation, and retain DUI counsel before that date so the case is handled correctly from the start. Write down everything you remember about the stop, the field sobriety tests, and the breath or blood test while it is fresh, and preserve receipts, texts, and any video.
