Will I Lose My CDL if I Got a DUI Off-Duty in California?

 Posted on August 05, 2026 in CDL

You can lose your commercial driver's license after an off-duty DUI in California, even if you weren't driving a commercial vehicle at the time. However, as is the case with any charge, you have the right to fight the allegations. If you've been arrested for DUI in 2026, talk to our Sonoma, CA CDL defense lawyer.

Attorney Paul Richard Burglin has represented more than 5,000 individuals charged with DUI over his 32-year career. And since 1985, Burglin Law Offices, P.C. has helped CDL holders facing legal troubles. Let us put that experience to work for you.

How Does a Regular DUI Affect a Commercial Driver's License?

Under California Vehicle Code Section 15300, a DUI conviction, even one that happened in a personal vehicle while off duty, can result in the disqualification of your commercial driver's license. The law treats commercial license holders differently than regular drivers, holding them to a stricter standard both on and off the job.

This means a DUI arrest during a weekend trip, a night out, or any other personal activity can still put your CDL at risk. Many drivers don't realize this distinction until they're already facing the consequences.

Why Are Commercial Drivers Held to a Higher Standard?

Commercial drivers operate large vehicles that can cause serious harm if driven unsafely. Because of this, federal and state regulators apply lower blood alcohol limits and harsher penalties to CDL holders.

What Is the Legal Blood Alcohol Limit for CDL Holders?

Regular drivers in California face DUI charges at a blood alcohol concentration of 0.08 percent or higher. For commercial drivers, that threshold drops to 0.04 percent, even when driving a personal vehicle. This means a CDL holder can be charged with DUI at a level that wouldn't result in any charge at all for a non-commercial driver.

How Long Will You Lose Your CDL After a DUI?

A first-time DUI conviction, even one that occurred off duty, typically results in a one-year disqualification of your commercial driver's license.  A second DUI offense, or certain combinations of serious violations, can result in a lifetime disqualification of your CDL. In some cases, a driver may be able to apply for reinstatement after 10 years. However, this isn't guaranteed and depends on the specific circumstances of the case.

Can You Get Your CDL Back After a Disqualification for DUI?

Whether or not you can get your CDL back depends on the nature of the offense and how much time has passed. First-time disqualifications are typically temporary and end automatically once the disqualification period is over. This is as long as other licensing requirements are met. Lifetime disqualifications are much harder to overcome and often require a lengthy waiting period and a strong showing of rehabilitation.

What Should You Do if You're Arrested for DUI While Off Duty as a CDL Holder?

Protecting your CDL starts the moment you're arrested, not after your case reaches court. Steps that can help protect your career include:

• Requesting a DMV hearing within 10 days of your arrest to challenge an automatic license suspension
• Avoiding any statements to police beyond basic identifying information
• Contacting a CDL defense lawyer as soon as possible after the arrest
• Gathering any evidence that supports your defense, such as witness information or receipts showing your timeline that night
• Notifying your employer only after speaking with a lawyer about how much information you're required to share

Missing the 10-day DMV hearing deadline is one of the most common mistakes drivers make. It can result in an automatic suspension even before the criminal case is resolved.

Can a Lawyer Help Reduce the Impact of a DUI on Your CDL?

A lawyer familiar with CDL cases can challenge the traffic stop, the accuracy of blood alcohol testing, and whether proper procedures were followed during your arrest. In some cases, a strong defense can lead to a reduced charge that doesn't carry the same disqualification consequences as a full DUI conviction. Every case depends on the specific facts involved. But exploring these options early gives you the best chance of protecting your license.
