Michigan Commercial Driver DUI
If you hold a CDL and you’ve been charged with a DUI in Michigan — even in your own personal vehicle, not a work truck — you’re facing a problem that goes well beyond the criminal case itself. Michigan law is clear and unforgiving on this point: any OWI conviction, regardless of the vehicle involved, results in an automatic minimum one-year suspension of your CDL.
There are no exceptions. There is no judge who can waive it, no deal that avoids it. The only way to protect your CDL is to avoid the conviction altogether.
Our firm concentrates in Michigan DUI cases, and we understand what’s at stake for someone whose livelihood depends on keeping their CDL privileges. This page explains what the law actually does to CDL holders, and what we look for in these cases.
The CDL DUI Rules Are Stricter Than Most People Realize
Michigan holds commercial drivers to a higher standard. While the legal BAC limit for regular drivers is 0.08%, CDL holders can be charged with a DUI while operating a commercial vehicle at just 0.04% under Michigan’s CDL statute — half the standard limit. Federal Department of Transportation regulations apply on top of Michigan law, which means a conviction triggers consequences at both the state and federal level.
Michigan’s implied consent law applies to CDL holders as well. If you’re suspected of impaired driving, you’re required to submit to breath, blood, or urine testing. Refusing can result in an automatic one-year CDL suspension even if you’re never convicted of anything.
And here’s the part that genuinely surprises people: none of this has anything to do with whether you were driving a commercial vehicle at the time. Get a DUI in your personal car on a Saturday night, and your CDL still gets suspended if you’re convicted. The law doesn’t make a distinction.
What a Conviction Actually Costs You
In the real world, most CDL holders who get charged with a DUI were driving their own personal vehicle — not a work truck. It doesn’t matter. A first DUI conviction still means an automatic one-year CDL disqualification, and the law makes no distinction about what you were driving.
A second offense is a lifetime CDL ban. That’s not hyperbole; that’s the statute. Reinstatement after a lifetime ban is possible after ten years, but it requires meeting specific federal rehabilitation requirements, and there are no guarantees.
Beyond the license itself, the employment picture gets complicated. Many trucking companies have zero-tolerance policies — meaning a DUI charge, not even a conviction, can trigger termination. Even after reinstatement, the conviction follows you through background checks and the federal Drug and Alcohol Clearinghouse.
Our firm has worked with CDL holders who, despite facing a suspension, were able to stay with their employer by temporarily moving out of the driver’s seat. It doesn’t always work out that way, but it happens more than people expect. The point is: the situation is serious, but it’s not always as catastrophic as it looks in the first 48 hours.
What We Actually Do in a CDL DUI Case
Because the CDL suspension is automatic upon a DUI conviction, the entire focus of the defense has to be on avoiding that conviction — or getting the charge reduced to something that doesn’t trigger the CDL penalty.
That means putting every piece of evidence under a magnifying glass — the traffic stop, the field sobriety tests, the breathalyzer calibration, the blood draw procedures — looking hard for anything that doesn’t hold up.
Success in a DUI case is best measured by what does NOT happen to you. For a CDL holder, that means keeping the conviction off your record — because once it’s there, the CDL consequences follow automatically and there’s nothing left to argue about.
If the evidence is solid and a reduction or dismissal isn’t achievable, we’ll tell you that up front. We won’t pretend otherwise and feed you false hope. What we will always do is make sure every angle has been explored before any decision is made about how to produce the very best result.
If You Hold a CDL, Time Matters
The earlier a lawyer gets involved in a CDL DUI case, the more options are available. Evidence gets reviewed, witnesses are identified, and legal issues can be spotted before they’re waived. Waiting until the last minute can limit what’s possible.
