In California, you can be charged with driving under the influence (DUI) under two primary legal standards:
- Per Se DUI: This occurs when a driver operates a motor vehicle with a blood alcohol content (BAC) of 0.08% or higher. For commercial drivers, the legal limit is 0.04%, and for drivers under 21, California has a zero-tolerance policy, with a threshold as low as 0.01%.
- Impairment-based DUI: Even if your BAC is below the legal limit, you can still be charged with a DUI if law enforcement believes that alcohol, drugs (including marijuana or prescription medications), or a combination of substances has impaired your ability to drive safely. DUI laws in California also cover the use of illicit drugs, controlled substances, or medications that can impair motor skills and judgment, even if those substances were legally prescribed.
Common Scenarios That Lead to DUI Arrests
Every DUI case begins with an initial law enforcement encounter. Our Simi Valley criminal defense lawyers have represented clients in a wide variety of situations that led to DUI charges, including:
- Traffic stops: Officers may pull a driver over for swerving, speeding, running a red light, or any other vehicle code violation. If they suspect impairment, the stop can escalate to a DUI investigation.
- Sobriety checkpoints: These are pre-planned stops where drivers are randomly checked for signs of impairment. These checkpoints are legal in California, but follow strict guidelines.
- Field sobriety tests: Officers may request that you perform physical or cognitive exercises—such as standing on one leg or walking in a straight line—to assess your coordination and mental clarity.
- Breath, blood, or urine testing: Chemical tests are used to detect BAC levels or the presence of drugs. Refusing to submit to testing can result in automatic license suspension and enhanced penalties.
Many arrests are based on subjective evaluations or faulty testing procedures. Our skilled DUI defense attorney can uncover weaknesses in how the stop and investigation were handled.
Immediate and Long-Term Consequences of a DUI Arrest
The penalties for a DUI conviction in California are substantial and go far beyond the courtroom. Even a first offense can lead to:
- License suspension: Automatic suspension can begin shortly after your arrest unless you request a DMV hearing within 10 days.
- Jail time: A first-time DUI may result in up to six months in county jail, while repeat offenses or aggravating circumstances can lead to longer incarceration.
- Fines and court fees: You may face thousands of dollars in penalties, along with the cost of DUI education programs and installation of an ignition interlock device.
- Probation: Most DUI convictions result in 3 to 5 years of probation, with strict conditions including mandatory counseling and community service.
- Increased insurance rates: A DUI on your record will typically cause your auto insurance premiums to skyrocket, or your policy may be canceled altogether.
- Criminal record and reputational damage: A DUI conviction is a permanent criminal record that may affect your ability to find employment, secure housing, or obtain a professional license.
Many people don’t realize how deeply a DUI conviction can disrupt their lives until it’s too late. That’s why having our experienced Simi Valley DUI lawyer advocating for you from day one is absolutely essential.
Types of DUI Cases We Handle in Simi Valley, CA
With years of experience handling DUI cases across Southern California, The Law Offices of Christopher Chaney have earned a reputation for results-driven, strategic DUI defense. Our team understands the complexities of California DUI law and the local nuances of the Simi Valley court system. Whether you’re facing your first arrest or dealing with enhanced felony charges, a seasoned DUI lawyer from our firm is equipped to handle your case with precision, urgency, and care.
We provide comprehensive defense across the full spectrum of DUI-related charges, including the following:
- First-time DUI in Simi Valley: If this is your first DUI offense, you’re likely overwhelmed and unsure of what to expect. First-time DUI convictions can still result in jail time, license suspension, and mandatory DUI classes. We work to reduce or dismiss charges and explore diversionary options to minimize long-term consequences.
- Repeat DUI offenses in Simi Valley: California imposes stricter penalties for second, third, and subsequent DUI offenses. Our firm aggressively defends clients facing repeat charges, fighting to reduce sentencing, avoid extended license revocation, and prevent felony classification.
- Felony DUI in Simi Valley: A DUI becomes a felony when it involves serious injury, multiple prior offenses, or aggravating factors like excessive speed or a minor in the vehicle. These charges require a high-level defense and a strategic courtroom approach. As an experienced DUI defense attorney in Simi Valley, we deliver the strong representation necessary for these high-stakes cases.
- Underage DUI in Simi Valley: California’s zero-tolerance law means drivers under 21 can be arrested with a BAC as low as 0.01%. We help young drivers and their families understand the law, minimize penalties, and protect educational and professional futures.
- DUI with injury in Simi Valley: If another person is injured and you’re accused of driving under the influence, you may face felony charges with severe penalties, including prison time and restitution. We analyze accident reports, causation, and chemical tests to uncover weaknesses in the prosecution’s case.
- Prescription drug DUI in Simi Valley: Many drivers are surprised to learn that taking prescribed medications—such as anti-anxiety drugs, pain relievers, or sleep aids—can result in a DUI arrest. These cases are complex and require a nuanced defense built on medical and legal insight.
- Marijuana DUI in Simi Valley: Despite legalization, driving under the influence of marijuana remains a crime. Because there is no fixed legal THC limit, marijuana DUIs often rely on subjective assessments. We challenge these assumptions and flawed testing protocols to protect our clients.
- CDL driver DUI in Simi Valley: Commercial drivers are held to a higher standard, with a legal limit of just 0.04% BAC. A DUI conviction can end a CDL holder’s career. We understand the high stakes and work tirelessly to protect your license and your livelihood.

- Out-of-state driver DUI in Simi Valley: Visitors and tourists arrested for a DUI in Simi Valley face unique legal hurdles. We provide local representation to out-of-state clients, helping them resolve their charges efficiently while minimizing travel and disruption.
Navigating DUI Proceedings in Simi Valley
Facing DUI charges in Simi Valley can be confusing, stressful, and overwhelming, especially for first-time offenders. At The Law Offices of Christopher Chaney, we understand how unfamiliar the legal system can feel, which is why we take the time to clearly explain every phase of the process. From your first consultation to the final resolution of your case, a dedicated DUI lawyer will stand by your side, protecting your rights and helping you make informed decisions.
Below is an overview of what you can expect during the DUI proceedings in Simi Valley.
After the Arrest: What Comes First
Immediately after a DUI arrest, you will likely be given:
- A Notice of Suspension from the DMV
- A citation to appear in court
- Possibly, a temporary license valid for 30 days
You have just 10 calendar days from the date of arrest to request a DMV hearing to challenge your license suspension. Failing to act quickly can result in automatic loss of driving privileges, even before your criminal case is heard.
Hiring a DUI defense attorney during this critical early window can help ensure that all necessary steps are taken promptly, preserving your rights and giving your attorney a head start on your defense.
Preparing for Your DUI Hearing
Your DUI case actually proceeds along two tracks: an administrative process with the California Department of Motor Vehicles (DMV) and a criminal process in the Ventura County Superior Court system. Each track requires its own strategy.
At the DMV hearing, we focus on preventing license suspension. In court, we begin gathering and analyzing:
- Police reports
- Body cam or dash cam footage
- Breathalyzer or blood test results
- Arrest procedures
- Any prior DUI history
We may also file early motions to suppress evidence or dismiss charges depending on what our investigation uncovers.
Achieving the Best Outcome Possible
The outcome of a DUI case depends on numerous factors: your prior record, the strength of the prosecution’s evidence, the circumstances of the arrest, and the skill of your attorney. At The Law Offices of Christopher Chaney, we strive for the best possible outcome in every case, whether that means:
- Full dismissal of charges
- Reduction from DUI to reckless driving (a “wet reckless”)
- Avoidance of jail time through community service or house arrest
- Minimizing fines and license suspension
With our comprehensive knowledge of California DUI law and deep experience in the Simi Valley court system, we craft smart, customized strategies to secure favorable results for our clients.
Strategic DUI Defense in Simi Valley
At The Law Offices of Christopher Chaney, we know that every DUI charge is built on a foundation of evidence, and we also know that evidence is not always as reliable or conclusive as the prosecution claims. As your DUI lawyer, our mission is to break down the state’s case piece by piece, expose its weaknesses, and build a powerful counter-strategy that puts you in the strongest position for success.
Here’s how our firm strategically defends DUI charges in Simi Valley, CA.
Understanding the Prosecution’s Burden
In any DUI case, the burden of proof lies entirely with the prosecution. They must prove beyond a reasonable doubt that:
- You were driving a vehicle
- You were under the influence of alcohol and/or drugs
- Your ability to drive was impaired, or your BAC was over the legal limit
Our job as your DUI defense attorney in Simi Valley, CA, is to challenge the prosecution at every stage of their case. If there are holes in their timeline, inconsistencies in witness statements, or procedural violations, we will find them and use them to your advantage.
Identifying Errors in Arrest Reports
Police officers must follow strict legal procedures when conducting a DUI stop and arrest. Unfortunately, they don’t always get it right. We comb through every detail of the arrest report to uncover:
- Unlawful traffic stops (no reasonable suspicion)
- Improperly administered field sobriety tests
- Failure to read Miranda rights
- Omissions or contradictions in the officer’s narrative
These errors may lead to suppression of evidence, weakening the prosecution’s case significantly—or even resulting in dismissal.
Disputing BAC Results and Test Validity
Breath and blood tests are common tools in DUI prosecutions, but they are far from foolproof. Our defense strategies include challenging:
- Breathalyzer calibration and maintenance logs
- Blood sample handling and storage protocols
- Mouth alcohol contamination (e.g., from mouthwash, GERD, or dental work)
- Unqualified test operators
We may also call upon toxicologists or forensic experts to testify that the test results were inaccurate or misleading. In marijuana or prescription drug DUIs, where no clear impairment thresholds exist, we challenge the subjective assessments made by officers at the scene.
