A DUI is serious for anyone, but for commercial drivers, it risks your career. CDL laws are stricter for you due to the larger vehicles and hazardous materials you manage. Federal and state rules, like Illinois CDL laws, demand a higher safety standard. A conviction can result in long-term or lifetime CDL disqualification.
If you’re asking, “Do you lose your CDL if you get a DUI?” the answer is yes, and the consequences start immediately. The moment you’re charged, your job and future are in jeopardy. Acting fast is crucial. Getting a DUI attorney right away gives you the best chance to protect your license and keep your career on track.

The Harsh Reality: CDL DUI Penalties You Can’t Afford to Ignore
The rules for commercial drivers are significantly stricter, and it’s essential to understand the immediate and long-term consequences.
The Lower Blood Alcohol Concentration (BAC) Limit
For most people driving a non-commercial motor vehicle, the legal alcohol level limit for drunk driving is a BAC rate of 0.08%. For a CDL holder operating a commercial motor vehicle, the limit is half that: 0.04%. This means that even a small amount of alcohol can lead to an arrest and a DUI charge. Furthermore, many trucking companies have a zero-tolerance policy and may require you to have 0.00% alcohol level.
License Disqualification is Swift
The first and most immediate threat is the loss of your commercial driver’s license. This loss happens in two ways:
1. Administrative Suspension: This happens right away, often because of a failed chemical test (like a breathalyzer test) or a refusal to take one. Implied consent rules for commercial drivers are tough. After receiving implied consent warnings, refusing a Breath or Chemical Testing can result in an automatic license suspension or disqualification, even if you are later found not guilty in court. Testing procedures must be followed exactly.

2. Criminal Conviction: A conviction in court for impaired driving charges will trigger additional, severe penalties.
First-Offense Penalties
A first-time DUI conviction in a commercial or personal vehicle will result in a mandatory one-year CDL suspension. If you were transporting hazardous materials at the time of the offense, that suspension jumps to three years.
Beyond the license suspension, you face:
- Fines and Court Costs
- Possible jail time
- Mandatory Programs
Second-Offense Consequences
A second major disqualifying offense, such as a prior DUI (driving under the influence) or refusal to test, has severe consequences. Federal regulations require a lifetime CDL disqualification, effectively ending your commercial driving career. While you may petition for reinstatement after 10 years, approval is not guaranteed, and the process is extremely challenging.
Ignition Interlock Device (IID)
For your personal driver’s license (Class A and other classifications), you may be able to get an ignition interlock license with an Interlock device installed, allowing you to drive non-commercially during your Mandatory Waiting Period. However, you cannot get a restricted or hardship license to continue driving a commercial motor vehicle during your CDL disqualification period.

How a DUI Affects Your Career, Employment, and Future
The most significant impact of a DUI on a commercial driver is the loss of their career.
Job Loss and Limited Employment Opportunities
Trucking companies have strict safety standards. Even a single DUI charge can lead to immediate termination or suspension, regardless of whether you were driving your commercial vehicle or your personal car. Why? Because a DUI makes you a major liability risk, leading to massive increases in insurance costs for your employer.
Can I get a CDL with a DUI? Yes, eventually, after serving the full disqualification period and meeting all reinstatement requirements. However, securing new employment opportunities with a DUI on your permanent background check is incredibly challenging. Many carriers simply will not hire a driver with a major disqualifying conviction, even years later.
Endorsements and Testing
A DUI conviction causes you to lose all CDL endorsements, including hazmat and passenger endorsements. To get them back, you must complete the entire reinstatement process retest, passing all knowledge and skills exams, and paying reinstatement or re-qualification fees. TSA may also deny or revoke the security clearances needed for certain endorsements, limiting the types of jobs you qualify for.
The Federal Clearinghouse
Every major DUI violation, positive drug or alcohol test, and CDL suspension is reported to the FMCSA Drug and Alcohol Clearinghouse. This national database is mandatory for all carriers to check, so the DUI follows you across state lines and directly affects your ability to get hired. Employers see Clearinghouse records instantly, making it much harder to secure future driving jobs.

Defending a CDL DUI: What Legal Strategies Can Help?
Facing a DUI as a commercial driver license holder is a two-front battle: the criminal case in court and the administrative action by the Department of Motor Vehicles (Division of Driver Licensing or CDL Unit). You need an attorney who is prepared to fight on both fronts.
Challenging the Evidence
A strong defense often focuses on finding flaws in the prosecution’s case.
- The Traffic Stop: Did the officer have a proper legal reason (reasonable suspicion) to pull over your motor vehicle? If the stop was unlawful, the evidence collected afterward may be thrown out.
- Chemical testing Results: Was the breathalyzer test equipment properly calibrated and maintained? Were the testing procedures followed exactly? Even small errors can make BAC results, including a high-rate DUI reading, unreliable.
- Field Sobriety Tests: Were the field sobriety tests administered correctly? Certain medical conditions or even road conditions can unfairly skew these results, suggesting impairment where none exists.
CDL-Specific Defense Options
CDL holders are usually not eligible for diversion or deferred prosecution programs that might keep a DUI off their record, so the defense strategy must be more targeted. In many cases, the best approach is negotiating for a non-DUI offense that won’t trigger automatic CDL disqualification.
A skilled DUI attorney may work to reduce the charge to something like reckless driving or another lesser traffic offense to protect your career. Securing a not-guilty verdict, a favorable plea, or pursuing an administrative review of the suspension are all key strategies focused on saving your livelihood.
