FMCSA Serious Traffic Violations: CDL Disqualification and Reinstatement

Under Federal Motor Carrier Safety Administration rules, serious traffic violations are a defined set of moving offenses — things like excessive speeding, reckless driving, and texting behind the wheel of a commercial vehicle — that don’t cost you your CDL on a single conviction, but stack quickly. A second conviction within three years brings a mandatory 60-day disqualification. A third within the same window brings 120 days. The offenses, the math, and the reporting duties are all set out in 49 CFR 383.51.1eCFR. 49 CFR 383.51 – Disqualification of Drivers

Which Offenses Count

Table 2 of 49 CFR 383.51 lists every offense the FMCSA treats as a serious traffic violation:1eCFR. 49 CFR 383.51 – Disqualification of Drivers

  • Driving 15 mph or more above the posted or regulated speed limit
  • Reckless driving, defined as willful disregard for safety
  • Improper or erratic lane changes
  • Following too closely
  • A traffic violation arising from an accident involving a fatality
  • Driving a CMV without ever having been issued a CDL or CLP
  • Driving a CMV without your CDL or CLP in your possession
  • Driving a CMV without the proper class of license or endorsements for the vehicle or cargo (for example, hauling hazmat without an H endorsement)
  • Texting while driving a CMV
  • Using a hand-held mobile telephone while driving a CMV

One narrow safe harbor exists for the possession offense. If you were cited for not having your CDL on you, you can avoid a conviction by showing the enforcement authority, before your court date, proof that you held a valid CDL on the day you were cited.2eCFR. 49 CFR 383.51 – Disqualification of Drivers That defense doesn’t help a driver who never held the license.

Serious violations sit in the middle tier of the FMCSA’s penalty structure. Major offenses — driving a CMV under the influence, leaving the scene of an accident, causing a fatality through negligent driving, using a CMV to commit a felony — are covered by Table 1 and carry a one-year disqualification for a first conviction (three years with hazmat) and a lifetime ban for a second.3Federal Motor Carrier Safety Administration. Disqualification of Drivers (383.51) The serious-violation category is different: one conviction is not enough on its own.

How Convictions Stack Into a Disqualification

A single serious traffic violation does not disqualify you. What triggers the penalty is the second conviction within a three-year period, measured from the date of the earlier offense. That second conviction carries a mandatory 60-day disqualification from operating any commercial motor vehicle.1eCFR. 49 CFR 383.51 – Disqualification of Drivers A third or subsequent conviction inside that same three-year window extends the disqualification to 120 days.

The offenses don’t have to be the same type to count together. A conviction for excessive speeding plus a conviction for following too closely is two serious violations. Each conviction must come from a separate incident.

A disqualification is nationwide. It doesn’t matter where the underlying violations happened, and moving to another state or applying for a new license elsewhere won’t get around it. State licensing agencies share these records through national databases. Motor carriers are prohibited from letting a disqualified driver operate a commercial vehicle for any reason during the disqualification period.

Violations in Your Personal Vehicle

Serious traffic violations you commit in your personal car can count toward CDL disqualification, but only when the conviction actually results in the revocation, cancellation, or suspension of your regular (non-commercial) driving privileges.1eCFR. 49 CFR 383.51 – Disqualification of Drivers A routine speeding ticket that only adds points to your record generally won’t reach your CDL.

Once that threshold is crossed, the math is the same as for CMV violations. A second qualifying conviction within three years brings 60 days; a third brings 120. The federal view is that losing your basic driving privileges signals you may not meet the safety standard for commercial operation.

Reporting a Conviction

Federal law puts the reporting duty on you, and the deadline is short. You must notify your current employer in writing within 30 days of any traffic conviction (other than parking), no matter which state it happened in and no matter what vehicle you were driving.4eCFR. 49 CFR 383.31 – Notification of Convictions for Driver Violations If you’re not employed at the time, you notify the state that issued your CDL instead.

If the conviction happened in a state other than the one that issued your license, there’s a second notice: you must also inform your licensing state’s designated official within 30 days.5eCFR. 49 CFR 383.31 – Notification of Convictions for Driver Violations Home-state convictions don’t require this step because your licensing state already has the record.

The written notice has to include:6eCFR. Notification of Convictions for Driver Violations

  • Your full legal name and CDL number
  • The date of conviction
  • The specific offense, and any resulting license suspension, revocation, or cancellation
  • Whether you were driving a commercial vehicle at the time
  • The location where the violation occurred
  • Your signature

Missing the notification can compound the original problem. Carriers rely on these reports to maintain compliance, and a driver who doesn’t report can leave the carrier unknowingly out of compliance during an audit.

Getting Your CDL Back

Federal regulations set the length of the disqualification but leave the reinstatement mechanics to the states.7eCFR. 49 CFR Part 383 Subpart D – Driver Disqualifications and Penalties Once your 60-day or 120-day period ends, your state licensing agency handles reactivation. Most states require you to apply in person, pay a reinstatement fee, and show that the disqualification period has fully elapsed. Fees generally run somewhere between about $45 and $130 depending on the state.

A traffic-related disqualification doesn’t automatically require a new DOT physical, but your existing medical examiner’s certificate still has to be valid. If it expired while you were disqualified, you’ll need to pass a new physical before you can drive again. Calling your state CDL office ahead of your reinstatement date is the quickest way to confirm what they’ll ask for.

If a Violation on Your Record Is Wrong

The FMCSA runs a system called DataQs for challenging entries in its federal safety databases.8Federal Motor Carrier Safety Administration. DataQs Through DataQs you can file a Request for Data Review to dispute an inaccurate or incomplete record. The system tracks the request and notifies you of the outcome.

DataQs deals with data accuracy inside federal records. It is not a substitute for fighting a citation in court, and it will not reverse a conviction. If you want to contest the underlying charge, that has to happen in the jurisdiction where you were cited, and ideally before the conviction is entered on your record in the first place.
