Under 21 DUI (Zero Tolerance)

Drivers under 21 can be penalized for a BAC of 0.01% or higher. Typically results in a one-year license suspension. If BAC exceeds 0.08%, misdemeanor charges and additional penalties may apply.

Commercial DUI (0.04% BAC or higher)

Commercial drivers face stricter limits. A first offense may include heavy fines, up to one year in jail, and a one-year suspension of commercial driving privileges. A second offense can lead to a lifetime ban.

DUI Causing Injury

It can be charged as a misdemeanor or a felony. Penalties range from fines up to $5,000 and 1–3 years license suspension to prison sentences of 2–10 years for felony cases.

Aggravated DUI

Factors like a BAC of 0.15% or higher, having a minor in the car, or excessive speeding can increase penalties. This often means higher fines, longer jail time, and extended license suspension, along with probation, DUI programs, and community service.

From First Call to Final Resolution: What to Expect When You Work with Geller Law, PC

A DUI charge in California moves fast. Knowing what comes next helps you stay ahead.

Step 1: Initial Consultation

Your first step is to talk with our attorney, Sam Geller. You’ll talk through what happened, when it happened, and what you’re facing. Sam will give you clear, honest answers.

Step 2: Case Review

Next, we look at all the evidence. This means police reports, breath or blood test results, dashcam footage, and arrest records. We look for weak points in the state’s case. A flawed field sobriety test or a broken chain of custody can change everything.

Step 3: Strategy Planning

Geller Law, PC, appears in court for you. We file motions, push back on weak evidence, and negotiate with prosecutors. California DUI cases can involve both criminal court and DMV hearings; we handle both.

Step 5: Resolution

Every case ends differently. Some result in reduced charges. Others may be dismissed on the basis of faulty evidence. We work toward the best outcome your case allows. You’ll know where things stand at every step.

Common DUI Defense Strategies

An effective DUI defense requires knowledge, experience, and strategic thinking. Our attorneys employ numerous defense strategies tailored to each unique case.

• Challenging Breathalyzer Accuracy: These devices require proper calibration and maintenance. We investigate whether the equipment was properly maintained and calibrated, or whether operator error occurred.
• Questioning Traffic Stop Legality: Police are required to have reasonable suspicion to initiate a traffic stop. We scrutinize whether the officer had legitimate cause to pull you over. Stops made without proper justification can render all subsequent evidence inadmissible.
• Exposing Blood Test Irregularities: We examine if proper protocols were followed during the collection, storage, and testing of blood samples. Chain-of-custody issues or improper handling can compromise results.
• Highlighting Procedural Violations: Officers have to follow specific procedures during a DUI arrest. We investigate if your Miranda rights were properly administered and if officers followed all required protocols.
• Medical Condition Defense: Certain medical conditions can mimic intoxication or affect breath test results. Conditions like GERD, diabetes, or even certain diets can produce false positives.
