What Counts as a Commercial DUI in California?
California holds commercial drivers to higher safety standards than other motorists. Under California Vehicle Code § 23152(d), it is unlawful for a person holding a commercial driver’s license (CDL) to operate a commercial vehicle with a blood alcohol concentration (BAC) of 0.04% or higher.
The BAC measures how much alcohol is in a person’s system. For most non-commercial drivers, the legal limit is 0.08%. For CDL holders, the limit is half that amount—even if the driver feels fine or shows few signs of impairment.
Why a Commercial DUI Charge Matters
A commercial DUI isn’t just another traffic violation. It can have serious consequences that go beyond fines and license suspension. Commercial drivers depend on their license for their livelihood, and a single conviction could end that career.
Penalties for a commercial DUI charge can include:
- A one-year suspension of your CDL for a first offense.\
- Permanent loss of your CDL for a second DUI conviction, even if it happens in a non-commercial vehicle
- Possible jail time, probation, or community service
- Mandatory DUI school and court fines
- A criminal record that affects job opportunities
Commercial drivers also follow federal rules from the Federal Motor Carrier Safety Administration (FMCSA). Breaking these rules can bring extra penalties and even block you from driving across state lines.
How a Whittier Commercial DUI Attorney Helps After an Arrest
A criminal defense lawyer can take action right away to protect your driving privileges and record. Legal representation is especially important for commercial drivers who must maintain a clean background check so they can continue to work.
A lawyer can:
- Explain how getting a DUI affects your commercial driver’s license.
- Review the traffic stop, arrest, and chemical testing process.
- Challenge inaccurate or incomplete BAC results.
- Speak for you at the California Department of Motor Vehicles (DMV) hearing and in court
- File an appeal if your license is suspended or if you are convicted.
- Negotiate with prosecutors for reduced or dismissed charges.
- Seek options such as probation, DUI programs, or limited driving privileges.
Your DUI attorney will look at every part of your arrest, including why you were stopped and how the evidence was handled. This helps with finding defenses that can make your case stronger.
When to Hire a Criminal Defense Lawyer for a Commercial DUI
If you are facing a DUI in Whittier, you don’t have to wait for formal charges to come in before you hire an attorney. Securing legal help early gives you a better chance to protect your license and build a defense.
You should contact a defense lawyer if you:
- Were arrested on a DUI charge while driving a commercial or personal vehicle
- Are being questioned by law enforcement about a suspected DUI
- Got a letter from the DMV about a license suspension
- Have a prior DUI on your record
- Are facing potential job loss because of your CDL status
A lawyer handling commercial DUI cases in Whittier can speak for you, stop you from saying anything that hurts your case, and protect your rights from the start of the investigation.
How California DUI Laws Apply to Commercial Drivers
The state’s DUI laws are detailed under California Vehicle Code §§ 23152 and 23153. Section 23152 covers driving under the influence of alcohol or drugs, while Section 23153 applies to DUI cases involving injury to another person.
A lawyer can explain how these laws apply to your situation. For example:
- You may face criminal penalties in court and administrative penalties through the DMV.
- You have only 10 days after your arrest to request a DMV hearing to challenge a license suspension.
- Even if your case involves prescription medication or a low BAC reading, prosecutors can still file charges under the “impairment” provision of the law.
An attorney can advise you on what to expect. To learn more, call Los Angeles DUI Lawyer for a free consultation.
Common Defenses Used in Whittier Commercial DUI Cases
Every DUI case has unique factors and circumstances that can affect a case’s outcome. A lawyer can use several strategies to challenge the prosecution’s case, depending on the facts.
Possible defenses include:
- Faulty or uncalibrated breathalyzer or blood testing equipment
- Unlawful traffic stop or arrest without probable cause
- Mishandling or contamination of blood samples
- Lack of clear signs of impairment
- Procedural errors by police or lab technicians
Even if your BAC reading was above the legal limit, an experienced defense lawyer can look at how the test was done and challenge results that seem wrong. This can help lower or even dismiss your charges.
Protecting Your Commercial Driver’s License and Future Career
For many drivers, a CDL is something they worked hard to earn. Losing it can take away their whole career. A DUI conviction can also make it harder to get or keep jobs with trucking companies, delivery services, or passenger transport companies.
A defense lawyer can:
- Act fast to stop the DMV from suspending your CDL right away.
- Argue for a restricted license to allow limited work driving.
- Challenge the evidence and fight for a reduced or dismissed charge.
- File appeals and seek alternative outcomes to preserve your record.
The legal process moves fast after a DUI arrest. Reaching out to an attorney early gives them more time to look at your case and build a defense for you.
What if You Have a Prior DUI?
Facing a second DUI is serious for any commercial driver, so acting early gives you a better chance to protect your future. You should still call a defense lawyer right away. They will review your record and build a strategy that fits your situation.
Sharing details about your prior case helps your attorney understand what the court may consider. They can check whether the old DUI was handled correctly, look for mistakes in the new arrest, and find ways to lower the impact of the new charge.
Your attorney can also ask for lighter penalties and push for outcomes that protect your CDL as much as possible.
