A DUI with a Commercial Driver’s License (CDL) is not a fine-and-move-on problem. Your job can be on the line.
Every Illinois DUI has two tracks:
- The criminal charge
- The statutory summary suspension of your driver’s license
For CDL holders, a third layer sits on top: federal CDL disqualification rules. Those rules are stricter than the rules for a regular license. The legal alcohol limit in a commercial motor vehicle (CMV) is .04% BAC — half of the .08% limit for most drivers.

Can you lose your CDL after a DUI?
Often, yes — at least for a time.
For a first DUI, many non-CDL drivers hope for court supervision. That can keep a conviction off the criminal record if you finish the court’s terms.
For a CDL holder, court supervision is usually a trap. Under federal rules, finishing court supervision for DUI still counts as a conviction for CDL disqualification. That can mean:
- One year off commercial driving for a first DUI
- Three years if you were hauling hazmat when arrested
- Even if you were in a personal vehicle, not a truck
A second DUI can permanently disqualify you from holding a CDL.
Losing commercial privileges can cost your job. A DUI mark on your record can also make it hard for other carriers to hire you.
That does not mean you have no options. CDL cases need both criminal DUI skill and a clear read of FMCSA / CDL rules. See also our DUI hub and first offense DUI.
Court dates: A DUI is a criminal charge. You appear for criminal dates — in person, or by Zoom only if that court authorizes Zoom for that date. We tell you what each date requires.
Other penalties for a CDL DUI in Illinois
On top of CDL disqualification, a DUI conviction can bring:
Jail and fines
A typical first DUI is a Class A misdemeanor: up to one year in jail and a fine up to $2,500. Later cases or aggravating facts can raise the stakes. A conviction also ties into license revocation and reinstatement waits. For CDL holders, a second DUI can mean permanent commercial disqualification.
Extra costs
- Court costs (often $1,000+ depending on the county)
- A drug/alcohol evaluation and any required classes or treatment
- Higher car insurance for years if a DUI goes on your record
The evaluation sorts you into a risk level (minimal, moderate, significant, or high). That level drives treatment hours and can affect sentencing talks.
Options when you’re charged with a CDL DUI
Why court supervision is usually wrong for CDL drivers
What looks like a “good” plea for a regular driver can end commercial driving for a year (or three with hazmat). Attorneys who rarely handle CDL cases sometimes miss this. We flag it early.
Reduced charge / alternative outcome
Sometimes the State will discuss a non-DUI charge such as reckless driving. That can avoid an automatic DUI-based CDL disqualification — but reckless driving is still a serious traffic violation. Two serious traffic violations in a set window can disqualify you from a CMV anyway, whether you were in a personal car or a commercial vehicle. Speeding, improper lane use, and texting while driving can also count. A plea only makes sense after we map your full abstract.
Fighting the charge
The cleanest way to protect your CDL is to challenge the case when the facts support it. Common angles:
- The stop: Police need a lawful reason to pull you over. Without it, later evidence can be suppressed.
- Breath or blood testing: Calibration, operator certification, timing gaps, and procedure errors matter.
- Field sobriety tests: These tests are subjective. Medical issues, nerves, lighting, or uneven ground can skew results.
Every file is different. There is no promised result.
Why CDL DUI defense is different
CDL cases mix Illinois DUI law with Federal Motor Carrier Safety Administration (FMCSA) rules. You need a plan for:
- The criminal case
- The summary suspension clock (often day 46)
- How any outcome hits commercial privileges
We build a GamePlan around your goals — keep driving commercially when possible, limit fallout when it is not, and keep you clear on each court step.
