Getting a notice to appear at West Valley Division after a DUI arrest can feel overwhelming. You don't know which building to go to, what will happen in the courtroom, whether you'll leave in handcuffs, or what the prosecutor will offer. This guide answers all of it — exactly what happens at your first DUI court date at West Valley Division — Rancho Cucamonga District, from the moment you walk in to the moment you walk out.
Where Is Rancho Cucamonga Superior Court?
West Valley Division — Rancho Cucamonga District: 8303 Haven Avenue Rancho Cucamonga, CA 91730 Phone: (909) 945-4131 Hours: Monday–Friday, 8:00 a.m. – 4:30 p.m. |
Parking and Arrival Tips
There is a large public parking lot on the north side of the courthouse building. Arrive at least 30 minutes before your listed hearing time. Bring a valid photo ID. You will pass through a security checkpoint — metal detector and bag X-ray — at the main entrance. Check the directory board in the lobby for your department number and floor. Department assignments can change, so always confirm on the board when you arrive. Dress business casual or better. What you wear signals to the judge and prosecutor whether you are taking the proceeding seriously.
What Is a DUI Arraignment?
The arraignment is your first formal court appearance on your DUI charge. It is not a trial. No witness testimony is taken, and no one determines guilt or innocence at an arraignment. It is a procedural step with three purposes: the charges are formally stated, your rights are confirmed, and you enter a plea.
The Three Things That Happen at Your DUI Arraignment
First, the charges are read. The judge confirms you understand what you are accused of — typically VC 23152(a) (driving under the influence) and VC 23152(b) (driving with a BAC of .08% or higher). Both charges are almost always filed together.
Second, your constitutional rights are confirmed. The judge walks through your right to a jury trial, your right to an attorney (including court-appointed counsel if you cannot afford one), and your right against self-incrimination.
Third, you enter a plea. For virtually every DUI defendant at arraignment, the correct plea is NOT GUILTY. This is true regardless of your BAC, whether an accident occurred, or whether you believe you have defenses. Do not plead guilty at arraignment.
Do Not Plead Guilty at Arraignment The DA's first offer is made before your attorney has reviewed a single piece of evidence. Pleading guilty at arraignment forecloses defenses that exist in a significant percentage of DUI cases — including unlawful traffic stops, faulty breathalyzer results, and improper field sobriety tests. |
What Will the San Bernardino County DA Offer at Arraignment?
The prosecutor assigned to your case will have reviewed the arrest report and typically has an initial plea offer ready at arraignment. Whether you should accept that offer is almost always: not at arraignment.
Typical First-Offense DUI Offer at West Valley Division - Rancho Cucamonga Superior Court
For a first-offense DUI with a BAC between .08 and .14, no injury, and no prior DUI within 10 years, the standard West Valley DA opening offer typically includes:
- 3 years of informal (summary) probation
- Fines and assessments — approximately $1,800–$2,500 total
- AB 541 three-month first-offender DUI program
- Ignition Interlock Device (IID) per DMV requirements
- No additional jail time beyond booking credit
This is the DA's opening position, not the ceiling. With an experienced attorney reviewing the stop, the chemical test records, and the officer's conduct, many first-offense DUI cases at West Valley resolve more favorably — and some are dismissed.
Second DUI Offer at West Valley Division - Rancho Cucamonga Superior Court
If you have a prior DUI within 10 years, the SB County DA treats this as a second offense. The standard offer typically includes 96 hours to 1 year county jail (often satisfied through work release or the Sheriff's Work Alternative Program), an 18-month SB-32 DUI program, mandatory IID, 3–5 years of probation, and higher fines. A second DUI at West Valley is a very different case from a first, and suppression motions become even more valuable.
Felony DUI Arraignment at West Valley Division - Rancho Cucamonga Superior Court
If your DUI involved injury (VC 23153), you have 3 prior DUIs within 10 years, or a prior felony DUI, the DA may file felony charges. Felony DUI arraignments at West Valley Division are heard in a felony department. Bail is set or reviewed at arraignment. The potential exposure — state prison vs. county jail — makes having an attorney before arraignment critical, not optional.
Should You Accept the First DA Offer?
In almost every case, no — not at arraignment. The first offer is made before your attorney has received any discovery, reviewed any video footage, checked the breathalyzer calibration records, or evaluated whether the traffic stop was lawful. Accepting at arraignment is the fastest path to a DUI conviction, and it forecloses defenses you may not even know you have.
What to Bring to Your DUI Court Date at West Valley Division
Documents to Bring
Bring your court notice or citation — the paper listing your court date, case number, department, and charges. If you are represented by an attorney, your attorney may appear without you for a misdemeanor arraignment (PC 977 waiver). Confirm this beforehand. If appearing without an attorney, bring your release paperwork from jail, including the pink DS-367 temporary license.
What to Wear
Business casual at minimum. A collared shirt, slacks, or a modest professional dress is appropriate. Avoid hats, flip-flops, athletic wear, or clothing with alcohol-related graphics. Your appearance in court communicates respect — or the lack of it — to everyone in the room.
What Happens After the Arraignment?
The Pretrial Conference
After you enter a not-guilty plea, the court sets a pretrial conference date — typically 4–8 weeks from arraignment. At the pretrial conference, your attorney will have reviewed all discovery and can respond to the DA's position, make a counter-offer, or request scheduling for a suppression hearing.
PC 1538.5 Suppression Motions
If there are grounds to challenge the legality of the traffic stop or chemical test, your attorney files a motion under Penal Code 1538.5 to suppress the evidence. Common grounds in SB County DUI cases include: unlawful traffic stop (officer lacked reasonable suspicion), improper field sobriety test administration, and breathalyzer calibration failures. A successful suppression motion typically results in case dismissal or a significant reduction in charges.
Resolution or Trial
Most DUI cases at West Valley Division resolve through a negotiated plea at or before the pretrial conference stage. Cases that cannot be resolved proceed to jury trial — typically 2–3 days for a misdemeanor DUI at West Valley Division. Kirk Tarman & Associates prepares every DUI case for trial from day one, even when trial is not the expected outcome.

FAQs — DUI Court Date at West Valley Division
Can my DUI case be dismissed at the arraignment itself?
Rarely. A dismissal at arraignment requires a clear defect in the charging documents or an obvious constitutional violation. In practice, dismissal comes after a successful suppression motion or after the prosecutor reviews discovery and determines the case cannot be proven at trial. Your attorney identifies dismissal opportunities as the case progresses.
What if I need an interpreter at West Valley Division?
West Valley Division provides court interpreters for non-English speakers. Have your attorney notify the court clerk in advance if you need an interpreter for Spanish, Vietnamese, or another language.
What if I need to reschedule my arraignment date?
Contact your attorney immediately. Do not simply miss your court date — failing to appear at a scheduled arraignment results in a bench warrant being issued for your arrest.
