A commercial DUI in California is not just another traffic offense — it is a direct threat to your livelihood, your professional reputation, and your future. As a CDL holder, your ability to drive is your income. One arrest can jeopardize everything you have worked for.
Commercial drivers are held to a stricter legal standard than other motorists. Even a first offense can trigger severe consequences, including a lengthy CDL disqualification. In many cases, the penalties extend beyond the courtroom and directly impact your employment, professional licenses, and long-term career opportunities.
At Gorelick Law Offices, Attorney Lynn Gorelick brings over 38 years of criminal defense experience, with a focused practice in DUI defense. She has handled thousands of DUI cases and extensive DMV Administrative Per Se hearings. She understands how California prosecutors build commercial DUI cases — and how the DMV moves quickly to suspend or revoke commercial driving privileges. Just as importantly, she knows how to challenge weak evidence, flawed testing procedures, and improper traffic stops.
Our approach is strategic, thorough, and aggressive when it counts. We carefully examine:
- The legality of the traffic stop
- Field sobriety test administration
- Breath and blood testing accuracy and calibration
- Officer training and report inconsistencies
- DMV procedural requirements
When your CDL and career are on the line, you need a lawyer who understands both the criminal court process and the administrative license system — and who moves fast to protect your rights.

Need A Commercial DUI Lawyer In California?
California commercial drivers face a lower legal BAC threshold than non-commercial drivers. While the standard limit for most adult drivers is 0.08%, CDL holders operating a commercial vehicle can be arrested and charged with DUI at just 0.04% BAC. That is half the standard limit.
This lower threshold means commercial drivers face greater risk — even when they believe they are within legal limits.
Beyond the standard DUI penalties imposed on all drivers, commercial drivers may face additional consequences, including:
- One-year CDL disqualification for a first offense
- Lifetime CDL disqualification for a second offense
- Immediate job loss or employment suspension
- Difficulty securing future driving positions
- Increased insurance premiums
- Criminal penalties, including fines, probation, DUI programs, and possible jail time
Importantly, even a DUI that occurs in your personal vehicle can affect your CDL. The DMV and criminal court operate separately, and both can impose penalties that impact your commercial driving privileges.
A DUI conviction can derail years of hard work in an instant. For many drivers, it means lost contracts, terminated employment, and long-term financial strain.
Fast action is critical. You generally have only 10 days from the date of arrest to request a DMV hearing to challenge the suspension of your license. Missing that deadline can result in automatic administrative penalties.
At Gorelick Law Offices, we act immediately. We request DMV hearings, review police reports, secure testing records, and begin building your defense without delay. Every case is different, and we tailor our strategy to your specific facts, driving history, and professional needs.
Your livelihood deserves serious protection.
Why California Commercial Drivers Trust Our DUI Defense Attorneys
Experience matters in DUI defense — especially for CDL holders whose careers depend on maintaining a clean driving record.
Attorney Lynn Gorelick brings a depth of experience that few defense attorneys can match:
- Over 38 years of criminal defense experience
- Thousands of DUI cases handled
- Extensive experience representing clients in DMV Administrative Per Se hearings
- Certified on DUI testing equipment used by Bay Area law enforcement, including Draeger breath testing devices and PAS systems
- Trained in administering the same NHTSA field sobriety tests used by police officers
Commercial DUI cases are highly technical. They involve not only criminal court proceedings but also separate DMV administrative actions that can disqualify your CDL — sometimes before your criminal case is resolved.
We understand how these cases are built, and more importantly, how to dismantle weak or flawed evidence.
Our firm carefully analyzes:
- Whether the traffic stop was lawful
- Whether the officer had probable cause to detain or arrest you
- How field sobriety tests were administered and scored
- Breath and blood test procedures and accuracy
- Calibration, maintenance, and certification records for testing equipment
- Chain of custody documentation for blood samples
- Officer observations, inconsistencies, and report errors
Many commercial DUI cases hinge on procedural mistakes, equipment malfunctions, or violations of constitutional rights. A careful, strategic review can reveal critical defense opportunities.
At Gorelick Law Offices, we do not make empty promises or unrealistic guarantees. We provide honest, straightforward guidance about your options and fight aggressively for the best possible outcome. Our goal is simple: protect your CDL, protect your record, and protect your future.

Common Commercial DUI Charges We Defend In California
Commercial drivers may face several types of DUI-related charges, and each carries serious potential consequences for their CDL and career.
We defend CDL holders against:
- DUI While Operating A Commercial Vehicle (0.04% BAC Or Higher)
Commercial drivers are subject to a lower legal limit when operating a commercial vehicle. Even a BAC below 0.08% can result in arrest and CDL disqualification. - DUI In A personal vehicle As A CDL holder
A DUI conviction in your personal vehicle can still impact your commercial driving privileges. - Refusal To Submit To chemical testing
Refusing a breath or blood test can result in enhanced penalties and separate administrative consequences through the DMV. - Drug DUI Involving Prescription Or Illegal Substances
DUI charges are not limited to alcohol. Prescription medications, over-the-counter drugs, and controlled substances can lead to arrest if officers believe they impair your ability to drive safely. - DUI Involving Accident Or Injury
When a DUI is connected to an accident, penalties may increase significantly and can result in felony charges. - Felony DUI
Prior convictions, injuries, or aggravating factors can elevate a DUI to a felony offense. - Multiple DUI offenses
Repeat offenses can lead to extended CDL disqualification, harsher criminal penalties, and long-term career consequences.
Even an arrest without a conviction can trigger administrative penalties affecting your CDL. The DMV can move forward with disqualification proceedings independent of the criminal court outcome.
Immediate legal representation can make a substantial difference. Early intervention allows us to request DMV hearings, preserve evidence, and begin challenging the case before deadlines expire.

What To Do If You're Arrested For A Commercial DUI In California
Being arrested for a commercial DUI can feel overwhelming. The decisions you make in the hours and days that follow are critical.
If you are arrested:
Remain Calm And Respectful.
Do not argue with officers or escalate the situation. Your behavior during the stop and arrest can be documented and used in court.
Do Not Volunteer Unnecessary Statements.
Anything you say can be included in the police report. You have the right to remain silent.
Request An Attorney Immediately.
Clearly state that you want to speak with a lawyer. Do not answer further questions without legal counsel.
Contact A DUI Defense Lawyer As Soon As Possible.
Commercial DUI cases involve both criminal court and DMV proceedings. The sooner a defense attorney becomes involved, the better your chances of protecting your CDL.
Act Quickly To Request A DMV Hearing.
In most cases, you have only 10 days from the date of arrest to request a DMV Administrative Per Se hearing. Missing this deadline can result in automatic license suspension or CDL disqualification.
It is important to understand that the DMV process is separate from your criminal case. Even if your criminal charge is reduced or dismissed, you could still face administrative penalties if the DMV process is not properly handled.
Early intervention allows us to:
- Request and prepare for your DMV hearing
- Review police reports and chemical test results
- Identify weaknesses in the prosecution's case
- Begin building a defense strategy tailored to your situation
The earlier we get involved, the more options you may have. Waiting limits your ability to challenge the case effectively.
If you have been arrested for a commercial DUI in California, do not delay.
FAQs About Commercial DUI Charges In California
1. What Is The Legal BAC Limit For CDL Holders?
For most drivers in California, the legal limit is 0.08%. However, if you are operating a commercial vehicle with a valid Commercial Driver's License (CDL), the legal limit is 0.04% BAC. That is half the standard limit.
This lower threshold reflects the heightened responsibility placed on commercial drivers who operate large or passenger-carrying vehicles. Even if you feel capable of driving safely, a BAC of 0.04% or higher while driving a commercial vehicle can result in arrest and CDL disqualification.
2. Can I Lose My CDL For A First DUI?
Yes. A first commercial DUI conviction can result in a one-year CDL disqualification.
If the offense involved transporting hazardous materials, the disqualification period can be longer. A second DUI offense can lead to lifetime CDL disqualification, even if the second offense occurred years later.
Because your CDL is tied directly to your employment, protecting it should be your top priority after an arrest.
3. What Happens If I Refuse A Chemical Test?
Refusing a breath or blood test after a lawful DUI arrest can trigger additional penalties under California's implied consent laws.
Consequences may include:
-
Automatic license suspension
-
Extended CDL disqualification
-
Enhanced penalties in court
-
Negative inferences are used against you.
Refusal cases are complex and highly technical. An experienced DUI attorney can review whether the refusal was properly documented and whether the officer followed required procedures.
4. Does A DUI In My Personal Car Affect My CDL?
Yes. Even if you were driving your personal vehicle at the time of arrest, a DUI conviction can still impact your commercial driving privileges.
The DMV treats DUI convictions seriously for all CDL holders, regardless of the type of vehicle involved. In many cases, your CDL can still be disqualified even though the offense occurred outside of work.
5. How Soon Must I Request A DMV Hearing?
In most cases, you have only 10 days from the date of your arrest to request a DMV Administrative Per Se hearing.
If you miss this deadline, your license — including your CDL — may be automatically suspended or disqualified. The DMV hearing is separate from your criminal court case, and failing to act quickly can limit your options.
6. Can A Commercial DUI Be Reduced Or Dismissed?
It depends on the specific facts of your case. Commercial DUI charges may be reduced or dismissed if there are weaknesses in the evidence, such as:
-
An unlawful traffic stop
-
Improperly administered field sobriety tests
-
Faulty breath or blood testing procedures
-
Inaccurate calibration or maintenance records
-
Inconsistencies in police reports
Each case must be carefully evaluated. A detailed review of the evidence often reveals defense opportunities that are not immediately obvious.
7. Are Jail Penalties Mandatory?
Not always. Jail time depends on factors such as:
-
Whether this is a first or a repeat offense
-
Your prior criminal record
-
Whether an accident or injury occurred
-
Aggravating circumstances
Some first-time offenses may result in probation, fines, and DUI education programs instead of jail. However, repeat or felony DUI charges can carry significantly harsher penalties.
8. What if I Was Under 0.08% But Over 0.04%?
If you were operating a commercial vehicle and your BAC was 0.04% or higher, you can still be charged with a commercial DUI — even if you were below 0.08%.
Additionally, officers can pursue DUI charges if they believe you were impaired, regardless of your specific BAC reading. Impairment-based charges do not require a BAC over a specific limit.
9. Will My Employer Be Notified?
In many cases, yes — especially if your CDL is suspended or disqualified. Employers often become aware of DUI-related actions through required reporting systems, insurance notifications, or background checks.
A commercial DUI can affect current employment, future job opportunities, and insurance eligibility within the transportation industry.
10. Why Is Hiring An Experienced DUI Lawyer Important?
Commercial DUI cases are more complex than standard DUI cases. They involve:
- Criminal court proceedings
- Separate DMV administrative hearings
- Strict federal and state CDL regulations
- Technical chemical testing evidence
- Career-impacting consequences
An experienced DUI attorney understands how to challenge breath and blood test results, question officer procedures, and navigate both court and DMV systems. Technical details often determine the outcome of these cases.
Protecting your CDL requires fast action, strategic planning, and deep knowledge of DUI law.
