CDL Traffic Violations (49 CFR 383)

For commercial drivers, a single ticket (even in a personal vehicle) can trigger CDL disqualification under 49 CFR 383. Federal rules and defenses that work.

A CDL Is a Federal License Held to Federal Rules

Your commercial driver’s license is issued by Wisconsin but governed by federal regulations under 49 CFR Part 383. That dual system is what makes CDL traffic violations so consequential. A ticket that is a minor forfeiture for a regular driver can be a career-ender for a CDL holder.

And critically, many CDL disqualifications apply to tickets issued in a personal vehicle, not just a commercial vehicle. That rule catches a lot of commercial drivers by surprise.

The law at a glance

Wisconsin implements the federal CDL rules at § 343.055. Under 49 CFR § 383.51, Serious Traffic Violations carry a 60-day disqualification for a second offense and 120 days for a third within three years. Major Offenses (DUI, leaving the scene, felony involving a vehicle, driving while disqualified) carry one-year disqualifications for a first offense, three years if hazardous materials are involved, and lifetime disqualification for a second major offense.

What Counts as a Serious Traffic Violation

Under 49 CFR § 383.5, Serious Traffic Violations include:

  • Excessive speeding, 15 mph or more over the posted limit.
  • Reckless driving.
  • Improper or erratic lane changes.
  • Following too closely.
  • Violations connected to a fatality in any vehicle.
  • Driving a commercial motor vehicle without holding a CDL, without the CDL in possession, or without the proper class or endorsements.
  • Using a handheld phone while driving a commercial vehicle.
  • Texting while driving a commercial vehicle.

Two of these in a three-year period triggers a 60-day disqualification. Three triggers 120 days.

What Counts as a Major Offense

Under 49 CFR § 383.51(b), Major Offenses include:

  • Operating a commercial motor vehicle with a BAC of 0.04 or higher (half the usual 0.08 limit).
  • OWI in any vehicle under state law.
  • Refusing a chemical test in connection with an OWI.
  • Leaving the scene of an accident in any vehicle.
  • Committing a felony involving the use of a vehicle.
  • Driving a commercial vehicle while disqualified.
  • Causing a fatality through negligent operation of a commercial vehicle.

A first conviction in any of these categories is a one-year disqualification (three years for HAZMAT drivers). A second is a lifetime disqualification, reinstatement-eligible only under narrow federal hardship provisions.

Why This Ties Back to OWI Defense

For CDL drivers, an OWI charge, even a first offense with a BAC below the civilian .08 threshold, carries a one-year career suspension in addition to whatever the state court does. Our OWI practice page is dui-owi-attorney and the OWI microsite is racineowi.com. The microsite has a dedicated CDL-OWI page that walks through the federal layer in depth.

If the underlying OWI is dismissed or reduced to a non-qualifying offense, the federal disqualification does not attach.

Defense Angles

  • Civilian-track conversion. Reducing a Serious Traffic Violation to a non-qualifying violation (certain equipment violations, parking-equivalent forfeitures, or non-moving charges) removes the federal CDL consequence.
  • Venue and charging review. Sometimes the State charges a § 346.62 reckless driving when § 346.57 speeding would fit the facts. Arguing charging merit can move the case to a non-serious category.
  • Speed-measurement challenges. Radar, laser, and pacing methods each have defenses, calibration, training records, visual-obstruction, target verification. A 15-over speed ticket reduced to 10-over is a CDL-saving outcome.
  • Underlying OWI attack. Probable cause for the stop, probable cause to arrest, implied-consent procedural defects, blood-draw challenges, and breath-instrument calibration records are all defensible in the OWI itself, which, if successful, removes the federal CDL consequence automatically.
  • DOT master-driver-record cleanup. The Wisconsin DOT and FMCSA master driver record sometimes reflects dispositions inconsistent with the court judgment. We audit it.

What Changes for HAZMAT Drivers

HAZMAT-endorsed drivers face longer disqualifications and additional TSA security-threat-assessment consequences. A conviction that triggers a one-year disqualification for a standard CDL holder triggers a three-year disqualification for a HAZMAT holder under 49 CFR § 383.51(b)(2). Your first call after the ticket should be to defense counsel, not to your employer.

Collateral Consequences

  • Job loss, most trucking, school-bus, and delivery employers suspend or terminate on any CDL disqualification.
  • Insurance surcharges are steeper for CDL holders than for standard drivers.
  • DOT medical-card complications can follow a disqualification even after reinstatement.
  • CSA (Compliance, Safety, Accountability) score impact for company-assigned drivers.
  • Employer MVR review, many CDL employers run motor-vehicle reports quarterly.

Call the Same Day the Ticket Is Issued

For a CDL, the federal reporting clock starts when the ticket is disposed of, not when it is issued. The window to get counsel involved and negotiate a non-disqualifying disposition is short. Call or text Cafferty & Scheidegger at (262) 632-5000. Free, confidential consultation.

Frequently Asked Questions

Can a CDL be disqualified for a violation in a personal vehicle?
Yes, and this catches most CDL holders by surprise. Under 49 C.F.R. § 383.51, serious traffic violations (speeding 15+ mph over, reckless driving, improper lane change, following too closely, texting or handheld phone use, driving without a CDL when required) count toward CDL disqualification regardless of whether the ticket was in a commercial or personal vehicle. Major offenses (OWI, leaving the scene of an accident, felony involving a motor vehicle) similarly count from any vehicle.
How many serious traffic violations trigger a CDL disqualification?
Under 49 C.F.R. § 383.51(c), two serious traffic violations within a 3-year period = 60-day disqualification; three within a 3-year period = 120-day disqualification. The 3-year window is rolling, not calendar. The federal disqualification runs in addition to any Wisconsin license suspension under § 343.32.
What's a major offense for CDL purposes?
Under 49 C.F.R. § 383.51(b), major offenses include: OWI in any vehicle (including personal); operating a CMV with BAC of 0.04 or higher; refusing a chemical test; leaving the scene of an accident in any vehicle; using a CMV in commission of a felony; driving a CMV while disqualified; and causing a fatality through negligent operation of a CMV. First conviction = 1-year disqualification (3 years if HAZMAT); second conviction = lifetime disqualification.
What's the BAC limit for a CDL holder in Wisconsin?
Two limits apply. While operating a CMV, the federal limit is 0.04 BAC under 49 C.F.R. § 383.51(b) and § 346.63(7), half the civilian 0.08 limit. While operating a personal vehicle, the standard 0.08 BAC under § 346.63 applies, but a conviction at any level still triggers the 1-year CDL disqualification under federal law because OWI in any vehicle is a major offense.
Can I keep my CDL if I beat the underlying traffic charge?
Yes. The federal CDL disqualification under 49 C.F.R. § 383.51 attaches only on conviction. Dismissal, acquittal, or amendment to a non-qualifying offense (a non-moving forfeiture, a defective-equipment violation, or in some cases a charge below the 15-mph serious-speeding threshold) prevents the disqualification entirely. This is why CDL cases warrant aggressive defense even on tickets that look minor on paper.
How long does a CDL disqualification stay on my driving record?
Major offense convictions count toward CDL disqualification for life under the second-offense lifetime-disqualification rule, even if decades pass between the first and second. Serious violations count for 3 years under 49 C.F.R. § 383.51(c) for the multi-violation disqualification calculation. The conviction itself stays on the FMCSA Pre-Employment Screening Program (PSP) report for 3 years and on the FMCSA Drug & Alcohol Clearinghouse for 5 years.
Does refusing a chemical test in a personal vehicle disqualify my CDL?
Yes. Under 49 C.F.R. § 383.51(b)(2)(i), refusing a chemical test under any state's implied-consent law is a major offense for CDL purposes, regardless of vehicle. First refusal = 1-year CDL disqualification (3 years if HAZMAT); second refusal = lifetime disqualification. This applies even if the underlying state-court refusal proceeding under § 343.305 is dismissed for procedural reasons, because the federal disqualification often attaches to the refusal itself.
Can I get a hardship CDL during a federal disqualification?
No. Unlike Wisconsin's occupational driver's license under § 343.10 (which is available to most regular-license holders during a suspension), 49 C.F.R. § 383.51 does not authorize a hardship CDL during a federal disqualification. Limited reinstatement is available only after the full disqualification period and only after meeting any state reinstatement requirements (SR-22, OWI assessment, IID compliance under § 343.301).
Do I have to report a CDL ticket to my employer?
Yes. Under 49 C.F.R. § 383.31, a CDL holder must notify their employer of any traffic violation conviction (other than parking) within 30 days, and must notify the state of issuance of any conviction in another state within 30 days. Failure to report is itself a sanction-eligible event. Many trucking employers terminate on any CDL serious-violation conviction even if the federal disqualification has not yet attached.
How does an out-of-state ticket affect my Wisconsin CDL?
Under the Driver License Compact and 49 C.F.R. Part 383, all CDL traffic convictions are reported to the state of issuance and posted to the National Driver Register and CDLIS (Commercial Driver License Information System). Wisconsin will treat an out-of-state CDL conviction as if it occurred in Wisconsin for disqualification calculations. An Illinois 80-mph ticket lands on your Wisconsin master driver record.
