What Happens If You Get a DWI in Missouri With a Commercial Driver’s License (CDL)?

Why CDL Holders Are Held to a Higher Standard

Driving a commercial vehicle in Missouri isn’t just a job; it’s a professional responsibility backed by state and federal regulation. When you hold a Commercial Driver’s License (CDL), the expectations are much higher than for regular drivers. You're operating larger, heavier, and often more dangerous vehicles, which is why any allegation of driving under the influence (DWI) is treated with greater severity.

Even if you’re pulled over while driving your personal car on a weekend, a DWI can affect your CDL and put your entire livelihood at risk. Missouri law, and federal guidelines from the Federal Motor Carrier Safety Administration (FMCSA), leave little room for leniency when it comes to DWI charges involving commercial drivers.

What Is Considered a DWI for Commercial Drivers?

In Missouri, the legal limit for blood alcohol content (BAC) for most drivers is 0.08%. However, for CDL holders operating a commercial motor vehicle (CMV), the legal limit is significantly lower: just 0.04%. That means even a single drink may be enough to put you over the legal threshold if you're behind the wheel of your truck, bus, or delivery van.

And it doesn't stop there; Missouri law treats DWI charges just as seriously if you're arrested while driving your personal vehicle. Many drivers assume that as long as they weren’t operating a commercial vehicle, their CDL is safe. Unfortunately, that’s not the case. A DWI conviction in any type of vehicle can trigger a CDL suspension.

CDL holders are also prohibited from refusing a chemical test (such as a breathalyzer or blood draw) without consequences. Refusing a test can result in an automatic one-year disqualification of your CDL under Missouri’s implied consent laws.

Penalties for CDL Holders Charged With DWI in Missouri

The penalties for a commercial driver charged with DWI can be devastating, even for a first offense. Here's what you could be facing:

  • CDL Disqualification: A first-time DWI offense carries a mandatory one-year disqualification of your CDL, whether or not you were operating a CMV at the time.
  • Hazmat Endorsement Penalty: If your CDL includes a hazardous materials endorsement, a DWI can result in a three-year disqualification.
  • Second Offense Consequences: A second DWI conviction leads to a lifetime disqualification of your CDL. Although reinstatement is possible after 10 years, it requires meeting strict eligibility criteria and is rarely granted.
  • Employment Loss: Most commercial driving companies have strict policies against hiring or retaining drivers with a DWI on their record. One conviction could cost you your job and make it difficult to find new employment in the industry.
  • Criminal Record: A DWI conviction is a misdemeanor criminal offense that goes on your permanent record and can affect background checks, future licensing, and more.

These penalties highlight just how high the stakes are for CDL holders. Unlike other drivers, your ability to work is directly tied to keeping your license clean. A single mistake or wrongful charge can bring your career to a grinding halt.

Administrative Actions vs. Criminal Charges

It's important to understand that DWI charges in Missouri involve two separate processes: the criminal case and the administrative license action by the Missouri Department of Revenue.

Once you are arrested for DWI, you face a possible suspension or revocation of your personal driving privileges. But as a CDL holder, you face an additional layer of punishment: your commercial license can be disqualified even if you’re allowed to keep your personal license.

To contest the administrative disqualification, you must request a hearing within 15 days of your arrest. Missing this deadline often means losing the opportunity to fight for your CDL. This is one of the most urgent deadlines CDL holders need to know about after a DWI arrest.

Can You Fight a CDL DWI in Missouri?

Absolutely. Being charged with DWI doesn’t mean you’re automatically guilty. There are many ways to challenge a DWI charge, especially when your career is on the line.

An experienced DWI defense attorney may be able to:

  • Challenge the legality of the traffic stop. Was there probable cause to pull you over?
  • Dispute the accuracy of breath or blood test results
  • Expose issues with how field sobriety tests were administered
  • Review video footage, officer reports, and bodycam evidence for errors
  • Advocate for reduced charges or an amendment that protects your CDL

Every case is different, and the defenses available to you will depend on the details of your arrest. But one thing is certain: the sooner you get legal help, the better your chances of saving your license and your livelihood.

What Should You Do After a DWI Arrest With a CDL?

If you’re a commercial driver arrested for DWI in Missouri, there are several steps you should take immediately to protect your rights:

  1. Request an administrative hearing within 15 days to challenge the suspension of your driving privileges.
  2. Consult a qualified DWI attorney who understands both state DWI law and federal CDL regulations.
  3. Gather documentation, including your driving record, employment policies, and any communication from the arresting agency or the Department of Revenue.
  4. Follow all court orders, including any bond conditions or alcohol evaluations, to demonstrate compliance and responsibility.

Avoid discussing your case with anyone except your attorney. Statements made to your employer or others may be used against you in court or by licensing authorities.
