Common Misconceptions About California DUI Laws: Separating Fact from Fiction

Redlands police officers frequently monitor the I-10 freeway and the streets surrounding downtown. A single mistake or a misunderstanding of the law can lead to handcuffs and a trip to the San Bernardino County jail. Many drivers believe they understand their rights, but they often rely on myths that lead to a conviction. If you want to protect your future, you must recognize the common misconceptions about California DUI laws and how separating fact from fiction can save your license.

We do not just handle cases; we win them because we are more educated in the science of DUI defense than the people trying to put you in jail. This guide exposes the lies you might have heard. It provides the truth about navigating the complexities of California DUI law.

Misconception 1: You are Safe if Your BAC is Under 0.08 Percent

The most dangerous myth in Redlands is that you cannot be arrested if you blow a 0.07 percent or lower. This is completely false. California law actually has two separate statutes for driving under the influence. Vehicle Code 23152(b) makes it illegal to drive with a blood alcohol concentration (BAC) of 0.08 percent or higher. This is the “per se” law.

But Vehicle Code 23152(a) makes it illegal to drive while under the influence of any alcoholic beverage or drug. Under this section, the prosecution does not need a specific number. They only need to prove that your physical or mental abilities were impaired to the point that you could no longer drive with the caution of a sober person. If an officer sees you swerving on Alabama Street and you blow a 0.05 percent, they can still arrest you. We have won many cases where the BAC was low, but the police tried to claim impairment anyway.

Misconception 2: Field Sobriety Tests are Mandatory

Police officers in San Bernardino County are trained to make you feel like you have no choice. They might tell you to step out of the car and follow my pen or walk this line. Most people comply because they think they have to. In reality, Field Sobriety Tests (FSTs) are completely voluntary in California. You have the right to refuse them.

These tests are designed to make you fail. They are subjective “divided attention” tasks that even a sober person can struggle to perform on the side of a noisy freeway at midnight. The officer is the only person who decides if you passed or failed. By taking these tests, you are simply handing the prosecution evidence to use against you. Still, refusing these tests does not result in a license suspension. The only test that is mandatory is the chemical test (breath or blood) after you have been lawfully arrested, as required by California’s Implied Consent law.

Misconception 3: You Must Answer All the Officer’s Questions

When a Redlands officer pulls you over, they usually start with questions like “How much have you had to drink?” or “Where are you coming from?” You might think being honest and cooperative will get you a break. It won’t. The officer is building a case against you. Every word you say is recorded and will appear in the police report.

You are required to show your driver’s license, registration, and proof of insurance under Vehicle Code 12951. Failing to present your license is an infraction, but willfully refusing to do so upon a lawful demand is a misdemeanor. Beyond providing those documents, you have a constitutional right to remain silent. You do not have to admit to drinking or provide a timeline of your night. Politely stating that you wish to remain silent and want to speak with your attorney is your best defense. We have seen many cases where a client’s own statements became the primary evidence used against them in court.

Misconception 4: A DUI is Just a Traffic Ticket

Some people treat a DUI like a speeding ticket that you can just pay and move on. This is a massive mistake. A DUI is a criminal offense that can lead to jail time, even for a first offense. Under Vehicle Code 23536, a conviction carries mandatory fines (starting at $390 plus penalty assessments), a driver’s license suspension, and mandatory enrollment in a DUI education program.

A conviction stays on your record for 10 years and can be used to increase the penalties for any future arrests. It can cost you your job, your professional license, and thousands of dollars in increased insurance premiums. For Redlands residents who work in professional fields, the stakes are even higher. We treat every case with extreme aggression because we know that a DUI is a life-altering event, not a minor citation.

Misconception 5: The DMV and the Court are the Same Process

This is perhaps the most confusing part of California DUI law. When police arrest you, you face two completely different silos. One is the criminal court case at the San Bernardino Superior Court. The other is the Administrative Per Se (APS) hearing with the California DMV.

You have exactly 10 days from the date of your arrest to request a DMV hearing. If you miss this deadline, your license will be automatically suspended 30 days after your arrest. Winning in court does not automatically save your license at the DMV, and losing at the DMV does not mean you are guilty in court. We handle both of these processes for our clients. We use the DMV hearing as an opportunity to cross-examine the officer and identify weaknesses in their testimony before we ever set foot in a courtroom.

Misconception 6: Breathalyzer and Blood Results are Always Accurate

The prosecution wants you to believe that the science is perfect. They want you to think that a 0.10 percent BAC result is an undeniable fact. We know better. We have spent years studying the technical mechanics of breath machines and the chemistry of blood testing.

Breathalyzers do not actually measure your blood alcohol; they measure the alcohol in your breath and multiply it using a mathematical formula. This formula assumes everyone is the same, but it doesn’t account for body temperature, hematocrit levels, or lung capacity. Blood samples can also be mishandled or fermented if the vials lack the proper preservatives. Under Title 17 of the California Code of Regulations, the state must follow strict rules for how these tests are conducted. If they miss even one step, we fight to have the results thrown out.

Misconception 7: 2026 Laws Don’t Change Your Defense Strategy

Drivers often assume that DUI laws remain stagnant. In 2026, legislative changes, such as AB 366, extended ignition interlock device (IID) requirements through 2033. Additionally, AB 321 has updated procedural rules regarding “wobbler” offenses, allowing us new opportunities to argue for reductions from felonies to misdemeanors earlier in the process. We stay better educated than the prosecution on these updates, so we can find exits they don’t even know exist.

Why Aggressive Representation is Your Only Choice

The state of California has unlimited resources to prosecute you. They have the police, the crime labs, and the district attorneys. You need a team that is more prepared and more educated than they are. We have won cases that other lawyers said were impossible because we look for the technicalities that others miss.
