DUI Lawyer in Rancho Cucamonga and the Inland Empire West

Attorney Advertising

A first DUI arrest in the West End of San Bernardino County starts two separate cases at once: a criminal case in the San Bernardino County Superior Court and a license case with the California DMV. They run on different clocks, and the DMV clock is the short one. The United Firm | La Liga Defensora, A.P.C. defends first-offense DUI cases for people who live and work in Rancho Cucamonga, Fontana, Ontario, Upland, Chino, Rialto and Pomona, and you can talk with us and hire us entirely by phone.

The 10-day DMV deadline comes first

If you were arrested for driving with a blood alcohol level of 0.08% or more, or you refused a chemical test, the officer usually takes your paper license and gives you a pink temporary license that lasts 30 days. You have 10 days from the arrest to request an Administrative Per Se (APS) hearing with the DMV (Vehicle Code 13558). If no one asks for the hearing, the suspension starts automatically when the temporary license runs out. For a first offense with a test result of 0.08% or more, that administrative suspension is generally four months; for a refusal it is one year.

Requesting the hearing keeps your options open. It usually keeps you driving until the hearing is decided, gives us the officer’s report and test records before the court case moves forward, and lets us question how the stop and the test were handled. DMV hearings can be held by video conference or by phone, so you usually do not have to take a day off to sit in a DMV office.

Where your court case will be heard

Most misdemeanor DUI cases from the West Valley are filed by the San Bernardino County District Attorney and heard at the Rancho Cucamonga District courthouse, 8303 Haven Avenue, Rancho Cucamonga. Your citation or release paperwork lists the courthouse and date assigned to your case. One local detail matters: Pomona and Claremont are in Los Angeles County, so an arrest there is prosecuted by the Los Angeles County District Attorney and heard at the Pomona Courthouse South, 400 Civic Center Plaza, Pomona, even though it is only a few minutes from Rancho Cucamonga.

The date on your citation or release paperwork is your arraignment. In many misdemeanor DUI cases, an attorney can appear for you under Penal Code 977 with your written authorization, although a judge can order you to be present in a DUI case. We tell you up front which hearings you need to attend and which ones we can cover.

What a first-offense DUI can mean

A first DUI under Vehicle Code 23152(a) or (b) is normally a misdemeanor. The law allows a range of penalties, including informal probation, fines and penalty assessments, a state-licensed DUI education program (three months for most first offenses, longer for a test of 0.20% or more), and a court-ordered license suspension. In many first-offense cases you can keep driving on a restricted license, often with an ignition interlock device. A DUI conviction also counts as a prior for ten years if there is a later case.

Every case turns on its own facts, so we do not quote outcomes. What we can tell you is what we look at and what choices you will have at each step.

How we review a first DUI case

The reason for the stop: whether the officer had a lawful basis to pull you over or detain you, including at a checkpoint.
Field sobriety tests: how they were explained, the road surface and lighting, and any medical or footwear issues that affect the results.
Breath testing: the 15-minute observation period and the device’s calibration and maintenance records under California’s Title 17 rules.
Blood testing: how the sample was drawn, stored and analyzed, and whether a retest of the sample is worth requesting.
Timing: when you drank and when you were tested, which can matter when the result is close to 0.08%.
Body-camera and dash-camera video from the arresting agency.

Depending on what the evidence shows, possible paths can include a motion to suppress evidence, negotiation for a reduced charge such as a ‘wet reckless’ (Vehicle Code 23103), or trial. Whether any of these is available depends on your facts and the prosecutor’s position.

Hire us without an office visit

Many people arrested in the Inland Empire commute to work across two counties and cannot lose a day. You can call, talk through what happened, and sign a written fee agreement from your phone. We request the DMV hearing, get the police report, and keep you updated by phone, text and email. If you have already missed the 10-day window, call anyway; there may still be steps we can take in the court case.

Frequently asked questions

How long do I have to request a DMV hearing after a DUI arrest in Rancho Cucamonga?

Ten days from the date of the arrest. The deadline is the same anywhere in California. If you miss it, the DMV suspension usually begins automatically when your 30-day temporary license runs out.

Do I have to go to court at the Rancho Cucamonga courthouse myself?

Not always. In many misdemeanor DUI cases, your attorney can appear for you under Penal Code 977, but the judge can require you to attend certain hearings. We will tell you which dates you must attend.

I was arrested in Pomona. Is that a San Bernardino County case?

No. Pomona is in Los Angeles County, so the case is filed by the Los Angeles County District Attorney and usually heard at the Pomona Courthouse South.

Can I keep driving to work after a first DUI?

Often, yes. Many first offenders qualify for a restricted license, sometimes with an ignition interlock device. The details depend on your test result, whether you refused, and your driving record.

Will a first DUI stay on my record forever?

A conviction counts as a prior for ten years in any later DUI case. After you complete probation, you may be able to ask the court to dismiss the conviction under Penal Code 1203.4, which helps with most private employers but does not erase it for DMV purposes.
