Texas CDL Traffic Violations and Their Harsher Penalties

A traffic ticket carries consequences for a CDL holder that a standard driver never faces. The same speeding or lane-change citation another driver can resolve quietly can put a commercial driving career at risk. This article is one of the topics in the guide to Texas traffic tickets and your options, and it explains what changes once a driver holds a CDL: which convictions count, why the usual ways of keeping a ticket off a record are closed, and how long a disqualification lasts.

Why the rules are stricter for CDL holders

Federal law sets a single national standard for commercial drivers, and Texas enforces it. The federal disqualification rules in 49 CFR § 383.51 apply in every state, and Texas incorporates them through the Texas Commercial Driver’s License Act.

Two features separate a CDL holder’s situation from an ordinary driver’s. First, a conviction counts even when the driver was in a personal vehicle. Texas defines “conviction” broadly in Tex. Transp. Code § 522.003 to include a plea of guilty or nolo contendere and the payment of a fine or court costs, “regardless of whether the penalty is suspended, probated, or rebated.” Paying a ticket by mail is a conviction for CDL purposes.

Second, federal rules bar states from “masking” a commercial driver’s conviction, hiding it from the driving record through diversion programs available to other drivers. Texas law matches that bar, which is why the two options in the next section are closed to CDL holders.

No deferred disposition or defensive driving

For most Texas drivers, two tools keep a traffic conviction off the record: deferred disposition, where the judge defers a finding of guilt while the driver completes conditions, and a driving safety course (defensive driving) that leads to dismissal. Both are unavailable to CDL holders.

Deferred disposition is governed by Tex. Code Crim. Proc. art. 45A.301, which states the subchapter does not apply to a violation relating to motor vehicle control, other than a parking violation, committed by a person who holds a commercial driver’s license or held one when the offense was committed. The driving safety course dismissal carries the same exclusion in Tex. Code Crim. Proc. art. 45A.351, which does not apply to an offense committed by a person who holds or held a CDL. Both provisions took effect January 1, 2025 as part of the recodification of Chapter 45 into Chapter 45A, though the exclusion for CDL holders is long-standing Texas policy.

A CDL holder who receives a moving-violation ticket has two realistic paths: pay it, which records a conviction, or contest it in court. There is no middle option of quietly completing a class to erase it.

What counts as a serious traffic violation

Not every ticket carries the same weight. The disqualification rules turn on whether a conviction is a “serious traffic violation,” a term Texas defines in Tex. Transp. Code § 522.003(25) to include:

• driving 15 miles per hour or more above the posted speed limit on a single charge;
• reckless driving under state or local law;
• improper or erratic lane changes;
• following the vehicle ahead too closely;
• a traffic-control violation arising in connection with a fatal collision; and
• driving a commercial vehicle without the proper CDL in possession or without the correct class or endorsement.

Parking, vehicle-weight, and vehicle-defect violations are excluded from the definition. A single serious violation does not trigger a disqualification on its own; the count within a set period is what matters.

How long a disqualification lasts

Texas ties the length of a disqualification to the type and number of convictions in Tex. Transp. Code § 522.081:

• 60 days for two serious traffic violations arising from separate incidents within a three-year period.
• 120 days for three serious traffic violations within a three-year period.
• One year on a first major offense: driving under the influence of alcohol or a controlled substance (including DWI), leaving the scene of a collision, using a vehicle to commit a felony, causing a death through negligent operation, or refusing a blood or breath test. A measured alcohol concentration of 0.04 or more in a commercial vehicle, or 0.08 or more in a personal vehicle, also brings a one-year disqualification.
• Three years for a major offense committed while transporting hazardous materials that must be placarded.
• Lifetime for two or more major offenses arising from separate incidents.

A first DWI is one of the major offenses on that list. The penalties for the underlying criminal case are covered in Texas DWI first offense penalties; for a CDL holder, that criminal sentence is only part of the cost, because the same conviction disqualifies the driver from commercial driving for a year.

Violations in a personal vehicle count too

The disqualification rules reach conduct behind the wheel of any vehicle. Tex. Transp. Code § 522.081 opens by stating that its serious-violation provision applies to a violation committed “while operating any motor vehicle, including a commercial motor vehicle.” A CDL holder who collects speeding and lane-change convictions in a personal pickup on the weekend can reach the two- or three-violation threshold the same as one driving a rig for work.

Out-of-service orders and railroad-grade-crossing violations carry their own separate disqualifications under the same chapter. A driver who violates an out-of-service order faces escalating disqualification periods that start higher than the serious-violation periods above.
