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