If you or someone you love was just arrested for DUI in Rancho Cucamonga, the next 24 hours matter more than most people realize. Between the booking process, a 10-day DMV deadline that most people miss, and your first court appearance at West Valley Division, there are decisions to make that directly affect your license, your record, and your freedom. This page walks you through exactly what happens — step by step — so you know what to expect and what to do first.
Step 1 — Arrest and Booking at West Valley Detention Center
After a DUI arrest in the Rancho Cucamonga area, you will typically be transported to West Valley Detention Center, located at 9500 Etiwanda Avenue in Rancho Cucamonga. This is San Bernardino County's primary West End jail facility, operated by the San Bernardino County Sheriff's Department.
What Happens During Booking?
During booking, deputies process your personal information, photograph you, and take your fingerprints. Your personal property is inventoried and stored. If you submitted to a breath test at the scene, those results are noted in the arrest report. If a blood draw was taken, the sample goes to the San Bernardino County crime lab — results typically take 4–8 weeks. You will be given your arraignment date before release.
How Long Will You Be Held?
For a standard first-offense DUI with no injury, most defendants are released within 6–12 hours, either on their own recognizance (OR) or after posting bail. In San Bernardino County, standard DUI bail is typically $5,000 for a first offense, though this varies by BAC level, prior record, and whether an accident was involved. If you were in an accident with injury, bail will be set higher and OR release is less likely.
Step 2 — The 10-Day Rule: Protecting Your Driver's License
This is the most time-sensitive step after a DUI arrest in California — and the most commonly missed. When you are arrested for DUI, the arresting officer takes your California driver's license and issues a pink temporary license (DS-367 form). That temporary license is valid for 30 days. But you have only 10 CALENDAR DAYS from the date of arrest to request an APS (Administrative Per Se) hearing with the California DMV.
Critical 10-Day Deadline You have 10 calendar days from your arrest date to request a DMV APS hearing. If you miss this window, your license is automatically suspended on day 31. Kirk Tarman & Associates contacts the DMV within 24 hours of being retained on every DUI case. |
What Is an APS Hearing?
An APS hearing is completely separate from your criminal court case. It is held through the DMV — not the courts — and determines whether your driving privilege will be suspended. If you do not request the hearing within 10 days, your license is automatically suspended on day 31. For a first-offense chemical test suspension, the suspension period is typically 4 months. For a refusal (declining the chemical test), it is 1 year. Requesting the hearing delays the suspension while your case is pending.
How to Request a DMV Hearing in San Bernardino County
The California DMV now handles most APS hearing requests through its online Driver Safety Portal and by phone. You do not need to visit a physical office to request your hearing.

You or your attorney can request the APS hearing online through the DMV Driver Safety Portal or by calling (833) 543-7703. This is one of the first things Kirk Tarman & Associates does for every DUI client — we contact the DMV within 24 hours of being retained on every case.
What Happens If You Miss the 10-Day Deadline?
If you miss the 10-day window, the DMV suspends your license automatically on day 31. You lose the right to contest the suspension. You may still be eligible for a restricted license — to drive to work and DUI school — after 30 days of suspension, but only after installing an Ignition Interlock Device (IID) at your expense.
Step 3 — Your Arraignment at West Valley Division
Your criminal DUI case will be heard at West Valley Division of San Bernardino Superior Court.
West Valley Division — Rancho Cucamonga Superior Court: 8303 Haven Avenue Rancho Cucamonga, CA 91730 Phone: (909) 945-4131 |
West Valley Division handles all misdemeanor and felony DUI cases originating from: Rancho Cucamonga, Ontario, Upland, Montclair, Alta Loma, Etiwanda, Chino, Chino Hills, Guasti, Fontana, Rialto, Bloomington, Crestmore, Lytle Creek area, and parts of Pomona. CHP arrests on the I-10, I-15, and SR-210 freeways through the West End of San Bernardino County also route to West Valley Division.
When Is Your Arraignment?
If released from custody, your arraignment date is printed on your release paperwork. For most first-offense defendants, arraignment is scheduled 30–45 days from the arrest date. If you remain in custody when charges are filed, you must be arraigned within 48–72 hours.
What Happens at Your DUI Arraignment?
Three things happen at arraignment: (1) The charges are formally read — typically VC 23152(a) (driving under the influence) and VC 23152(b) (driving with a BAC of .08% or higher). Both are normally filed together. (2) Your constitutional rights are confirmed — right to a jury trial, right to an attorney, and right against self-incrimination. (3) You enter a plea. In almost every DUI case, the correct plea at arraignment is NOT GUILTY. This preserves all your options while your attorney reviews the evidence.
Should You Have an Attorney at Arraignment?
Yes — and having an attorney before arraignment is even better. For misdemeanor DUI cases, your attorney can often appear on your behalf without requiring your personal presence (PC 977 waiver). Your attorney will also review the DA's initial offer before the hearing and begin requesting the police report, body camera footage, and chemical test records the same day.
Step 4 — Pretrial Hearings and the DA's Offer
After arraignment, your case enters the pretrial phase. This is where the vast majority of DUI cases in San Bernardino County are resolved — through a negotiated plea, a successful suppression motion, or outright dismissal.
What Does the SB County DA Typically Offer for a First DUI at West Valley?
For a first-offense DUI at West Valley Division with a BAC of .08–.14, no accident, and no injury, the standard opening offer from the DA typically includes:
- 3 years of informal (summary) probation
- Fines and assessments totaling approximately $1,800–$2,500
- AB 541 first-offender DUI program (3 months at a licensed SB County provider)
- Ignition Interlock Device (IID) per DMV requirements
- No additional jail time beyond booking credit
These are starting-point numbers, not final answers. With proper legal representation and a thorough review of the evidence, many first-offense cases at West Valley resolve more favorably — and some are dismissed.
What Does Kirk Tarman Do Between Arraignment and Pretrial?
Our office requests all discovery: the arrest report, body camera and dashcam footage, breathalyzer calibration and maintenance records, and blood test chain of custody (if a blood draw was taken). We evaluate whether there are grounds to file a PC 1538.5 suppression motion challenging the legality of the traffic stop or the chemical test results. A successful suppression motion can result in reduced charges or full dismissal of the case.
Step 5 — Resolution or Trial at West Valley Division
Most DUI cases in San Bernardino County resolve before trial. If the DA's offer is reasonable and the evidence is strong, a negotiated plea may be the right outcome. But if the stop was unlawful, the field sobriety tests were conducted improperly, or the chemical test results are questionable, we take the case to trial — and we are prepared to do exactly that.
How Long Does a DUI Case Take at West Valley Division?
A standard first-offense misdemeanor DUI at West Valley Division typically takes 3–6 months from arraignment to resolution. Cases with pending blood test results from the crime lab often take 6–9 months. Felony DUI cases involving injury, a 4th offense, or a prior felony take 6–18 months if they proceed to trial.
Frequently Asked Questions
Do I need to appear at my arraignment in person?
For misdemeanor DUI charges at West Valley Division, your attorney can file a PC 977 waiver and appear on your behalf. In many cases, you do not need to appear at the arraignment at all. Confirm this with your attorney when you are retained.
Will my DUI stay on my record?
A DUI conviction stays on your California driving record for 10 years and counts as a prior offense if you are arrested for DUI again within that period. After completing probation, a first-offense DUI may be eligible for expungement under PC 1203.4 — which sets aside the conviction and replaces it with a not-guilty finding in the court record.
My DUI was on the freeway — does it still go to West Valley Division?
Yes. CHP arrests on the I-10, I-15, I-210, and SR-60 through the West End of San Bernardino County are processed through the West End DA's office and heard at West Valley Division. The arresting agency does not change your courthouse assignment.
Can a first-offense DUI be reduced to a lesser charge?
Yes, in appropriate cases. A "wet reckless" (VC 23103 with VC 23103.5 notation) is a lesser charge that can sometimes be negotiated with the SB County DA. It carries lower fines, shorter probation, and less insurance impact — but it is still priorable (counts as a prior DUI if you are arrested again within 10 years).
