CDL Serious Traffic Violations and Disqualification Periods

Under federal rules, CDL serious traffic violations and disqualification periods work on a three-year rolling count: one conviction on its own carries no federal disqualification, two within three years disqualify you from operating a commercial motor vehicle for 60 days, and three within three years bring a 120-day disqualification. The qualifying offenses are set out in Table 2 of 49 CFR 383.51, and the count follows you across state lines through a national database, so a ticket in one state and a ticket in another combine on your home state’s record.¹

Which Offenses Count as Serious Traffic Violations

Ten offenses fall into the serious category under 49 CFR 383.51:¹

Speeding 15 mph or more over the posted or regulated limit.
Reckless driving as defined by state or local law, including driving with willful or wanton disregard for the safety of others.
Improper or erratic lane changes.
Following too closely.
Any traffic violation (other than parking) arising from an accident that killed someone.
Driving a CMV without ever having obtained a CDL.
Driving a CMV without the physical CDL card in your possession. If you show the court before your appearance date that you held a valid CDL when cited, you will not be found guilty of this offense.
Driving a CMV without the proper class of license or the endorsements required for the passengers or cargo on board.
Texting while driving a CMV, which includes manually entering or reading text, email, instant messages, or web content on an electronic device.
Using a handheld mobile phone while driving a CMV, including while temporarily stopped in traffic.

The texting and handheld phone rules treat “driving” as covering time spent stopped at a light or sitting in a jam. To use a handheld phone legally, you have to pull completely off the road.

How the 60-Day and 120-Day Disqualifications Are Counted

The first serious traffic conviction does not trigger a federal disqualification on its own. The clock starts mattering with the second:²

Two serious violations in a CMV within three years: 60 days.
Three or more serious violations in a CMV within three years: 120 days.

The offenses do not have to match. A speeding conviction paired with a texting conviction counts as two, and any other mix from the list works the same way. They also do not have to occur in the same state. Every CDL conviction flows into the Commercial Driver’s License Information System, which links state licensing agencies nationwide, so out-of-state tickets combine with your home-state record.

One detail catches drivers off guard: the three-year window runs from the dates of the offenses themselves, not the dates of conviction.³ A court delay of several months does not push a ticket outside the window.

When a Ticket in Your Personal Car Counts

A serious traffic violation committed in your personal vehicle can count toward CDL disqualification, but only if the conviction also results in the revocation, cancellation, or suspension of your regular driver’s license or non-CMV driving privileges.¹ When that condition is met, the same 60-day and 120-day periods apply.

A routine speeding ticket in your personal car that stays under the 15 mph threshold and produces no license action will not touch your CDL. A reckless driving conviction that costs you your regular license will. As a working rule, any off-duty driving that puts your personal license at risk puts your commercial license at risk too.

Serious Violations Compared With Major Offenses

Serious traffic violations are the middle tier of CDL enforcement, not the worst. A separate list of major offenses under Table 1 of 49 CFR 383.51 carries much harsher penalties, and it is worth knowing where the line falls so you do not confuse the two. Major offenses include driving under the influence, a BAC of 0.04 or higher in a CMV, refusing an alcohol test, leaving the scene of an accident, using a CMV to commit a felony, and causing a fatality through negligent CMV operation. Each carries a one-year disqualification for a first offense and a lifetime disqualification for a second.¹

If the first major offense happens while hauling hazardous materials, the initial disqualification is three years rather than one. Using a CMV in drug trafficking or human trafficking brings a lifetime disqualification with no eligibility for reinstatement. Most major offenses apply whether committed in a CMV or a personal vehicle.

Railroad Crossing and Out-of-Service Violations

Two other categories run on their own separate schedules and are easy to mistake for serious traffic violations.

Railroad-Highway Grade Crossings

Failing to properly approach, stop at, or clear a railroad crossing, or disobeying crossing signals or a traffic officer at a crossing, triggers disqualification on the first conviction, not the second:¹

First conviction: at least 60 days.
Second conviction within three years: at least 120 days.
Third within three years: at least one year.

Out-of-Service Orders

Driving a CMV in violation of an out-of-service order carries the steepest short-term penalties in the CDL system. For non-hazardous loads, a first violation brings 180 days to one year of disqualification; a second within ten years brings two to five years; a third within ten years brings three to five years. When hazardous materials or passenger transport are involved, a first offense brings 180 days to two years, and a second brings three to five years. Drivers convicted of violating an out-of-service order also face civil penalties of at least $3,961 for a first conviction and at least $7,924 for a second.⁴

Reporting a Conviction Within 30 Days

Even a single conviction that never triggers a disqualification still triggers a reporting obligation. Any CDL holder convicted of a traffic violation other than parking, in any vehicle, must notify their current employer in writing within 30 days of the conviction date. If you are not currently employed, you notify the state that issued your CDL instead. If the conviction happened in a state other than the one that issued your license, you must also notify your licensing state’s designated official within the same 30 days.⁵

The written notice has to include your full name, driver’s license number, conviction date, the specific offense, whether the violation occurred in a commercial vehicle, the location of the offense, and your signature. Missing the deadline exposes you to additional administrative consequences and gives your employer grounds for termination.

Getting Your CDL Back After the Disqualification

Once a 60-day or 120-day period runs, reinstatement is generally straightforward if nothing else is pending against your record. Federal regulations do not lay out a reinstatement application process for standard serious-violation disqualifications; that piece is handled by the state agency that issued your CDL. Some states restore your privileges automatically when the clock runs out. Others require you to submit a reinstatement application and pay a fee, and those fees typically run from roughly $15 to $500.

State recordkeeping rules mean the convictions themselves stick around. States must retain convictions, disqualifications, and other licensing actions on your CDLIS driver record for at least three years, and some keep them longer.⁶ Because the retention period matches the three-year serious-violation window, an old conviction stops counting toward a new disqualification once it ages out, even if it still appears on your record.

Reinstatement after a lifetime disqualification for a major offense works differently. Most states allow an application after ten years if the driver has completed an approved rehabilitation program. Drivers disqualified for using a CMV in drug trafficking or human trafficking are permanently ineligible for reinstatement under any circumstances.¹
