Facing a DUI in Nevada City? Let’s Fight for Your Future, Together.

You didn’t plan for a night in historic downtown Nevada City to end with a flashing light in your rearview mirror. But now that it has, you need an advocate who understands the local Nevada County Superior Court system and knows how to win.

At The Win Law Firm, we help local residents and visitors alike protect their licenses, freedom, and reputations after a DUI arrest in Nevada City and the surrounding Foothills. Whether you were stopped on Highway 49, Broad Street, or near the Rood Center, we build aggressive, localized legal defenses tailored to your unique situation.

DUI Charges Can Derail Your Life in Nevada County

If you’ve been arrested for driving under the influence (DUI) in Nevada City, Grass Valley, or the San Juan Ridge, you are likely facing:

  • Mandatory Court Appearances: Most cases are heard at the Nevada County Courthouse at 201 Church Street.
  • Automatic License Suspension: The DMV starts the clock immediately upon your arrest.
  • Steep Nevada County Fines: Court assessments in our county can significantly increase the base fine.
  • Local DUI Programs: Mandatory enrollment in providers like Community Recovery Resources (CoRR).
  • Ignition Interlock Device (IID): Required installation to maintain driving privileges.

For commercial drivers, local business owners, and students, a conviction at the Nevada City courthouse can follow you for years, impacting your ability to commute through the winding roads of the Sierra Foothills.

A Former Prosecutor Who Knows Both Sides

Kenny Nguyen is a former California prosecutor who now defends Nevada City clients against DUI charges. He has handled thousands of cases, including:

  • First-Time DUI: Navigating the “standard” local penalties to keep you out of jail.
  • Felony DUI: Aggressive defense for cases involving injury or multiple priors.
  • High BAC Enhancements: Defending against the increased penalties for BAC over 0.15% or 0.20%.
  • Underage DUI: Protecting the futures of young drivers in the Nevada Joint Union High School District.
  • Refusal Cases: Challenging the “implied consent” allegations when chemical tests were declined.

As a former prosecutor, Kenny knows how the Nevada County District Attorney’s office builds its cases. He uses this “insider” knowledge to find weaknesses in the prosecution’s evidence—from improper calibration of breathalyzers used by the Nevada City PD to unlawful stops by the CHP on Highway 20.

Comprehensive DUI Defense Services in Nevada City

When you’re facing a DUI charge, the stakes go far beyond a simple traffic ticket. Your ability to drive, keep your job, and maintain your freedom are all on the line. That’s why The Win Law Firm provides full-scope DUI defense services – from challenging the legality of your stop to fighting for you at DMV hearings and in court. Whether you’re in Nevada County or the surrounding areas, our team delivers aggressive, informed, and proactive legal defense tailored to your situation. We don’t just show up – we show up prepared to win.

No two DUI cases are alike – and we never use a one-size-fits-all defense. Attorney Kenny Nguyen personally reviews every detail of your case, including:

  • Reason for the traffic stop – Did law enforcement have lawful probable cause?
  • Field sobriety test conditions – Were they administered properly under NHTSA standards?
  • Breathalyzer machine records – Is there a history of calibration errors or maintenance issues?
  • Blood sample chain of custody – Were lab procedures followed precisely to avoid contamination?

We look for procedural mistakes, rights violations, and scientific flaws that can result in reduced or dismissed charges. If your rights were violated at any stage, we’ll fight to suppress that evidence in court.

After a DUI arrest in California, the DMV initiates an Administrative Per Se (APS) action to suspend your license – even before your court case begins.

You have just 10 days from the arrest date to request a hearing. If you miss this deadline, your license will automatically be suspended – even if you’re found not guilty later in court.

We handle every step of the DMV process, including:

  • Timely DMV hearing request submission
  • Legal representation at the DMV hearing
  • Cross-examination of arresting officers
  • Presentation of legal or scientific defenses to stop the suspension
  • Applying for a restricted license or IID program, if needed

Don’t lose your license before your case even starts – let us fight the DMV for you.

The criminal court process involves multiple stages – and we manage each one while preparing your defense:

  • Arraignment representation: Ensure you enter the right plea and protect your options.
  • Discovery & evidence review: We obtain all police reports, lab results, video, and audio to identify inconsistencies.
  • Pre-trial motions: We may file motions to suppress evidence, dismiss charges, or request alternative sentencing.
  • Plea negotiations: If appropriate, we work to reduce the DUI to a “wet reckless” or lesser charge to avoid mandatory sentencing.
  • Trial advocacy: If your case goes to trial, you’ll be represented by a former prosecutor with proven courtroom skill.

We aim for full dismissals when possible – and strategic damage control when not.

Felony DUI charges often arise when:

  • It’s your fourth DUI in 10 years
  • You caused injury or death in a DUI accident
  • You had a minor in the vehicle
  • You have prior felony DUI convictions

Felony charges carry state prison time, license revocation up to 5 years, and serious long-term consequences.

We evaluate whether your case can be reduced to a misdemeanor, challenge aggravating factors, or negotiate for alternatives like treatment or SCRAM monitoring. The earlier we act, the more options we have.

DUI cases rely heavily on chemical and observational evidence – but this evidence is often flawed. We dig deep into:

  • Breathalyzer calibration logs and officer certifications
  • Blood test lab protocols, handling timelines, and contamination risks
  • Dashcam or bodycam footage to contradict officer narratives
  • Radio dispatch and field notes for inconsistencies in procedures

This level of scrutiny often uncovers errors that open the door to charge reductions or full dismissal.

If you’ve already been convicted of DUI, all is not lost. We help clients clean up their records through:

  • DUI expungement under California Penal Code § 1203.4
  • Early probation termination petitions
  • Record sealing or Certificate of Rehabilitation (in select cases)

Expungement allows you to legally state you were not convicted in most private employment settings – and removes the public stigma of a DUI.

100% DMV Hearing Win Rate
June 2025 Victories from The Win Law Firm

When it comes to protecting your driver’s license after a DUI arrest, winning the DMV Admin Per Se hearing is everything. In June 2025 alone, The Win Law Firm achieved a perfect win rate — securing four separate “Orders of Set Aside” for our clients, meaning no automatic license suspension from the DMV.

Why does that matter? Because losing the DMV hearing often signals the start of even worse consequences — and brings you one step closer to a DUI conviction.

  • Mandatory Ignition Interlock Device (IID) installation
  • Required SR-22 insurance filing
  • Steep DMV license reinstatement fees

And that’s before the criminal case even begins…

A DUI in Nevada City can cost thousands of dollars when you factor in court fines, DUI school, increased insurance premiums, ignition interlock device fees, and lost wages. The total financial impact often exceeds $10,000 over time.

Jail is possible, but not mandatory. Many first-time offenders qualify for alternatives such as probation, DUI education programs, or community service. An experienced DUI lawyer can often reduce or eliminate jail exposure.

If the DMV suspension goes into effect, a first DUI typically results in a four-month suspension. However, this can often be avoided or shortened by winning the DMV hearing or obtaining a restricted license.

In many cases, yes. You may qualify for a restricted license or ignition interlock device that allows you to drive to work, school, and medical appointments while your case is pending.

Refusal triggers an automatic one-year license suspension and additional penalties. However, refusals are often legally challengeable, especially if police failed to properly advise you of the consequences.

Yes. Unlike alcohol, there is no legal THC limit. Prosecutors must prove actual impairment. These cases are often easier to challenge because there is no clear scientific standard.

Many DUI cases are reduced to reckless driving or dismissed entirely due to faulty stops, testing errors, or rights violations. Early legal intervention gives you the best chance at a favorable outcome.

A DUI stays on your driving record for ten years for sentencing purposes. However, expungement may allow it to be removed from most public background checks.
