Los Angeles CDL DUI Defense Lawyer
Protecting Your Livelihood with a Commercial Driver DUI Attorney in Los Angeles, CA
If you hold a commercial driver's license and have been arrested for driving under the influence, contacting a Los Angeles CDL DUI defense lawyer from our firm today is the most critical step you can take. For commercial drivers, the stakes of a DUI are far higher than for the average motorist. Under California Vehicle Code Section 23152(d), the legal blood alcohol concentration limit is reduced to 0.04 percent when you are operating a commercial vehicle. This strict standard means that even a very small amount of alcohol can lead to a DUI charge and the immediate jeopardy of your career.
At The Law Offices of Christopher Chaney, we provide a calm and professional environment for drivers who are facing the life-altering prospect of losing their CDL. We understand that your license is not just a permit to drive but the foundation of your livelihood and your family's financial security. Our firm is dedicated to providing the strategic and empathetic advocacy you need to challenge the prosecution's evidence and protect your professional standing. Whether the arrest occurred in your commercial rig or your personal vehicle, we are committed to defending your rights with the highest level of care. Contact our firm today through our online contact form to schedule a free, confidential consultation.

California law holds commercial drivers to a much higher standard of conduct due to the size and weight of the vehicles they operate. While the standard legal limit for most adults is 0.08 percent, commercial drivers can be charged with a DUI for having a blood alcohol level of 0.04 percent or higher while on the job. It is also important to note that a commercial driver can face a CDL suspension even if they are convicted for a DUI while driving their personal car with a 0.08 percent blood alcohol concentration. In both scenarios, the legal system views the offense as a major violation of the trust placed in professional drivers.
The administrative consequences are often swifter than the criminal court process. Upon a DUI arrest, the DMV begins an administrative per se action that can result in the automatic disqualification of your commercial driving privileges. A commercial driver DUI attorney in Los Angeles, CA, is essential for requesting a DMV hearing within the strict ten-day window to contest this suspension. Without a successful defense at both the DMV and in criminal court, a first-time conviction will result in a mandatory one-year suspension of your CDL with no option for a restricted commercial license.

The Step-by-Step Legal Process for CDL DUI Cases
The procedural path for a commercial DUI involves two separate but parallel tracks that require careful management by your legal team:
- The ten-day DMV deadline: You must request an administrative hearing within ten days of your arrest to stop the automatic suspension of your license.
- The criminal arraignment: This is your first appearance in court, where the judge reads the formal charges and sets bail or conditions of release.
- Discovery and evidence review: Your attorney obtains all police reports, maintenance logs for testing equipment, and any available video footage.
- The DMV administrative hearing: Your lawyer contests the suspension by challenging the legality of the stop and the accuracy of the chemical test.
- The preliminary hearing or pre-trial motions: In felony cases or serious misdemeanors, we work to suppress evidence obtained through constitutional violations.
- Plea negotiations: Your attorney may negotiate for a reduced charge, such as a wet reckless, to avoid the mandatory one-year CDL disqualification.
- The jury trial: If no resolution is reached, a jury determines if the prosecution has proven the charges beyond a reasonable doubt.
Throughout these stages, your attorney works to identify procedural errors and scientific flaws that can be used to protect your license and your record.
How a CDL DUI Conviction Can Threaten Your Future
The penalties for a commercial driver convicted of a DUI are devastating and often end driving careers permanently. CDL disqualification rules are strict. Certain convictions trigger mandatory penalties under state and federal law.
Potential consequences include:
- Mandatory CDL disqualification: A first offense results in a one-year loss of all commercial driving privileges, while a second offense leads to a lifetime ban.
- No restricted commercial license: Unlike standard drivers, CDL holders cannot obtain a restricted license to drive a commercial vehicle for work during their suspension.
- Significant criminal fines: Court fines and assessments can total thousands of dollars, further straining the finances of those unable to work.
- Jail time and probation: A conviction can result in up to 6 months in county jail and 3 to 5 years of informal probation.
- Increased insurance costs: Even if you eventually regain your CDL, the cost of commercial insurance may be prohibitively expensive or lead to uninsurability.
- Loss of employment: Most trucking companies and delivery services have zero-tolerance policies for DUI convictions and will terminate employment immediately.
Early legal intervention by a commercial driver DUI attorney in Los Angeles, CA, is the most effective way to seek a resolution that preserves your ability to earn a living.
Strategic Methods for Defending You Against CDL DUI Charges
Building a defense for a professional driver requires a meticulous review of both the facts of the arrest and the technicalities of the testing equipment. A Los Angeles CDL DUI defense lawyer may utilize several strategies, including:
- Challenging the initial traffic stop: If the officer lacked probable cause or reasonable suspicion to pull you over, all subsequent evidence may be suppressed.
- Disputing the chemical test accuracy: We investigate if the breathalyzer was properly calibrated or if the blood sample was handled according to strict lab protocols.
- Rising blood alcohol defense: We can use expert testimony to show your blood alcohol concentration was below the limit while driving, but rose during the time before the test.
- Inaccuracy of field sobriety tests: We argue that fatigue, weather conditions, or physical injuries made these subjective tests unreliable measures of impairment.
By focusing on these strategic areas, your attorney works to create reasonable doubt and pursue a dismissal or a reduction of the charges that saves your commercial license.
