Utah CDL Traffic Violations: Serious & Major Offenses for Truck Drivers

Utah CDL Traffic Violations: What Commercial Truck Drivers Need to Know

A traffic ticket in Utah can have far more serious consequences for a Commercial Driver's License ("CDL") holder than for an ordinary motorist. For professional truck drivers, a traffic conviction can threaten employment, commercial driving privileges, and the driver's livelihood. This is especially critical for out-of-state CDL holders traveling through Utah on Interstates 15, 80, 70, 84, or other Utah highways.

A driver licensed in California, Texas, Idaho, Nevada, Colorado, or another state may receive a Utah citation without realizing that the resulting conviction can affect commercial driving privileges in their home state. Under Utah law and federal regulations, certain offenses fall into two important classifications:

• "Serious traffic violations," which can result in disqualification when multiple qualifying convictions occur within a three-year period.
• "Major offenses," which can result in a commercial driving disqualification after a single conviction or qualifying administrative action.

Whether the driver was operating a commercial motor vehicle (CMV) or a personal automobile is frequently critical in determining the impact of a violation.

1. What Is a Serious Traffic Violation Under Utah Law?

Utah Code § 53-3-402(18) identifies ten categories of serious traffic violations for CDL purposes:

• Excessive speeding: Driving 15 miles per hour or more over the posted speed limit. An amended charge to under 15 miles is very helpful, but not determinative on insurance underwriting or your employment.
• Reckless driving: Operating a motor vehicle recklessly as defined by Utah or applicable local law.
• Improper or erratic lane changes: Making dangerous, improper, or erratic traffic lane changes.
• Following too closely: Following another vehicle too closely.
• Traffic violations involving a fatal accident: Violating another motor vehicle traffic law in connection with a fatal traffic accident.
• Operating a CMV without a CDL or commercial driver instruction permit (CDIP): Operating a commercial vehicle without having obtained the required commercial license or permit.
• Operating a CMV without the proper CDL class or endorsement: Driving a commercial vehicle without the required license class or endorsement for the vehicle, passengers, or cargo.
• Operating a CMV without the CDL or CDIP certificate in the driver's possession: Violating Utah Code § 53-3-404 by failing to possess the required licensing document, subject to applicable defenses.
• Prohibited wireless communication device use: Using a wireless communication device while operating a CMV in violation of Utah Code § 41-6a-1716.
• Prohibited handheld mobile telephone use: Using a handheld mobile telephone while operating a CMV in violation of 49 C.F.R. § 392.82. Utah Code 41-6a-1617 bans using cell phones while driving in many ways with few exceptions.

The statute does not require every listed violation to occur in a commercial vehicle. However, several offenses expressly require the operation of a CMV. For example, a CDL holder driving a personal pickup truck can commit a serious speeding violation by traveling 15 mph over the speed limit. Conversely, driving a CMV without the proper CDL endorsement necessarily involves a commercial vehicle.

2. What Is a Serious Traffic Violation Under Federal CDL Regulations?

Federal law separately identifies serious traffic violations in 49 C.F.R. § 383.51(c), Table 2. These federal regulations identify the following ten categories:

• Excessive speeding: Driving 15 mph or more above the regulated or posted speed limit.
• Reckless driving: Driving in willful or wanton disregard for the safety of people or property, as defined by state or local law.
• Improper or erratic lane changes: Making improper or erratic traffic lane changes.
• Following too closely: Following another vehicle too closely.
• Traffic offenses connected to a fatal accident: Violating a state or local motor vehicle traffic-control law, other than a parking violation, in connection with a fatal accident.
• Driving a CMV without obtaining a CLP or CDL: Operating a CMV without first obtaining the required commercial learner's permit or commercial driver's license.
• Driving a CMV without possessing the CLP or CDL: Operating a CMV without the required license or permit in the driver's possession, subject to the regulation's proof-of-valid-license exception.
• Driving a CMV without the proper commercial license class or endorsements: Operating a vehicle without the correct CLP/CDL class or necessary endorsements for the vehicle, passengers, or cargo.
• Unlawful texting while driving a CMV: Violating a state or local traffic-control law restricting or prohibiting texting while driving a commercial motor vehicle.
• Unlawful handheld mobile telephone use while driving a CMV: Violating a state or local traffic-control law restricting or prohibiting handheld mobile telephone use while driving a commercial motor vehicle.

Utah's definition substantially tracks the federal regulation. The important question is not merely whether the officer cited the driver for an offense labeled "serious." The question is whether the conduct and resulting conviction qualify under the applicable Utah and federal CDL laws.

3. The Three-Year Lookback: When Serious Traffic Violations Cause CDL Disqualification

Under Utah Code § 53-3-414(6) and 49 C.F.R. § 383.51(c), multiple qualifying serious traffic violations can cause the driver to lose the right to operate a CMV.

The federal minimum disqualifications are:

The three-year lookback is a rolling period, not a calendar-year calculation. For example, assume a commercial truck driver receives these convictions arising from separate incidents:

• January 15, 2025: Speeding 17 mph over the limit in Utah while operating a tractor-trailer.
• September 10, 2026: Following too closely on I-80 while operating a commercial truck.
• February 20, 2027: Reckless driving in Price, Utah, while operating a commercial truck.

Assuming the applicable federal counting requirements are satisfied, the first two convictions would subject the driver to a 60-day disqualification. The third qualifying violation within the same three-year period would result in a 120-day disqualification.

The offenses need not be identical. Excessive speeding, following too closely, and reckless driving can be counted together. The incidents also need not occur in Utah. A commercial driver may accumulate qualifying convictions in multiple states. Importantly, the counting rules require separate incidents. Multiple charges arising from one traffic stop should not automatically be treated as multiple separate incidents for purposes of this three-year disqualification provision.

4. Does It Matter Whether the CDL Driver Was Driving a Commercial Truck or a Personal Vehicle?

Yes. This distinction can determine whether a serious traffic conviction results in CDL disqualification.

Under Utah Code § 53-3-414(6), two serious traffic violations committed while operating commercial motor vehicles, arising from separate incidents within three years, can produce a 60-day disqualification. Three qualifying violations can produce a 120-day disqualification.

However, a different rule applies to serious traffic offenses committed in non-commercial vehicles. Utah Code § 53-3-414(12), consistent with 49 C.F.R. § 383.51(c), addresses serious traffic violations committed in non-CMVs. For qualifying non-CMV serious traffic violations, the federal disqualification rule requires the conviction to result in the revocation, cancellation, or suspension of the driver's license or non-CMV driving privileges. Utah likewise imposes an additional licensing-consequence requirement.

Example A: Speeding in a commercial truck

A CDL holder is cited for traveling 85 mph in a 65-mph zone while operating a tractor-trailer in Utah. The alleged speed is 20 mph over the limit and therefore meets the serious-traffic-violation speeding threshold. A qualifying conviction may count toward the driver's three-year serious-violation history.

Example B: Speeding in a personal automobile

The same CDL holder receives a speeding citation for traveling 85 mph in a 65-mph zone while driving a personal automobile on vacation. The alleged conduct still falls within the federal serious-speeding classification. But for the federal non-CMV serious-violation disqualification rule to apply, the required license suspension, revocation, or cancellation condition must also be met.

Consequently, a speeding conviction in a personal vehicle does not necessarily result in the same CDL disqualification consequences as an identical conviction in a commercial truck. This is one reason why CDL defense counsel should determine precisely what vehicle the defendant was operating when the citation was issued.

5. What Is a Major CDL Offense Under Federal Law?

Major offenses are more consequential than ordinary serious traffic violations. Under 49 C.F.R. § 383.51(b), Table 1, the following ten categories constitute major CDL offenses:

• Driving under the influence of alcohol: Operating a motor vehicle under the influence of alcohol as prescribed by state law.
• Driving under the influence of a controlled substance: Operating a motor vehicle while under the influence of a controlled substance.
• Commercial vehicle alcohol concentration of 0.04 or more: Operating a CMV with an alcohol concentration of 0.04 or greater.
• Refusal to submit to required alcohol testing: Refusing testing required under applicable implied-consent laws or regulations.
• Leaving the scene of an accident: Leaving the scene of a motor vehicle accident in violation of applicable law.
• Using a vehicle to commit a felony: Using a motor vehicle in the commission of a felony other than the specifically identified drug-trafficking or human-trafficking felonies.
• Driving a CMV while commercially disqualified: Driving a CMV after the driver's commercial license or driving privilege has been revoked, suspended, canceled, or disqualified because of qualifying previous CMV violations.
• Negligently causing a fatality while operating a CMV: Causing a death through negligent CMV operation, including applicable manslaughter or negligent-homicide offenses.
• Using a motor vehicle to commit certain controlled-substance felonies: Using a vehicle in the commission of a felony involving the manufacture, distribution, or dispensing of a controlled substance.
• Using a CMV to commit certain human-trafficking felonies: Using a commercial motor vehicle in the commission of a felony involving severe forms of trafficking in persons.

The final two categories carry particularly severe consequences: lifetime commercial disqualification without eligibility for the ordinary ten-year reinstatement procedure.

6. What Are the Major CDL Disqualifying Offenses Under Utah Law?

Utah Code § 53-3-414 addresses major disqualifying conduct and the resulting administrative sanctions. The Utah statute expressly identifies the following offenses and circumstances:

• Driving while impaired or under the influence: Driving a motor vehicle while impaired by alcohol, drugs, controlled substances, or a combination.
• Driving a CMV with an alcohol concentration of 0.04 or greater: The commercial-vehicle alcohol threshold.
• Leaving the scene of a motor vehicle accident: Leaving the scene of an accident involving a vehicle the person was driving.
• Failing to provide required assistance or identification: Failure to comply with the duties imposed in connection with an accident causing injury or death under Utah Code § 41-6a-401.3.
• Using a motor vehicle in the commission of a felony: Using a vehicle to commit a felony.
• Refusing required alcohol or drug testing: Refusal to submit to applicable chemical testing.
• Operating a CMV while disqualified: Operating a commercial vehicle while the CDL is disqualified for a qualifying offense.
• Negligent operation of a CMV resulting in death: Including applicable manslaughter, negligent homicide, and automobile homicide offenses.
• Using a motor vehicle to commit specified controlled-substance felonies: Felonies involving manufacturing, distributing, or dispensing controlled substances.
• Using a motor vehicle to commit a qualifying severe human-trafficking felony: Subject to Utah's statutory requirements and the controlling federal provisions.

Utah also authorizes disqualification in specified circumstances involving administrative DUI action, including under § 53-3-414(14). The major-offense classification does not necessarily depend upon whether an offense is charged as a misdemeanor or a felony. A misdemeanor DUI, for example, can result in a one-year commercial driving disqualification.

7. How Long Does a Major Offense Disqualify a CDL Driver?

For most first major offenses, the required federal disqualification period is one year.

For certain lifetime disqualifications, federal regulations permit a state to consider reinstatement after ten years and completion of an approved rehabilitation program. Reinstatement is not automatic, and some offenses are expressly ineligible.

Unlike serious traffic violations, there is no general three-year lookback limiting the accumulation of major offenses for lifetime disqualification.

8. A Major Offense in a Personal Automobile Can Still Destroy a Truck Driver's Career

A CDL holder does not have to be driving a tractor-trailer to lose commercial driving privileges for a major offense. Consider a truck driver who is arrested for DUI while driving a personal passenger car in Utah. If the driver is convicted of qualifying DUI, federal law generally requires a one-year commercial disqualification, even though the driver was not working and was not operating a commercial vehicle. The driver may also face consequences involving ordinary driving privileges under Utah law.

A second qualifying major offense arising from a separate incident can result in lifetime commercial disqualification. The federal major-offense table expressly distinguishes offenses that apply in non-CMVs from those that can only be committed while operating a CMV. For instance, a personal-vehicle DUI can be a major CDL offense. However, the specific violation of operating a CMV at an alcohol concentration of 0.04 or more necessarily requires commercial-vehicle operation.

9. Utah's 0.05 DUI Limit Is Different from the 0.04 Commercial Vehicle Standard

Utah is known for its general 0.05 blood-alcohol concentration DUI threshold, although impairment-based DUI can exist independently of a particular test result. Commercial truck drivers face a separate federal and Utah commercial-vehicle alcohol standard.

Under Utah Code § 53-3-418 and 49 C.F.R. § 383.51, driving a commercial motor vehicle with an alcohol concentration of 0.04 or more is a major disqualifying offense. Even a driver below 0.04 can face an out-of-service consequence for prohibited alcohol use in connection with commercial driving. Utah Code § 53-3-417 prohibits driving a commercial motor vehicle while having a measurable or detectable amount of alcohol in the body and provides for a 24-hour out-of-service period in specified circumstances.

A 24-hour out-of-service order should not be confused with a one-year CDL disqualification. They are different regulatory consequences.

10. Can a CDL Driver Enter a Plea in Abeyance to Avoid Losing a Commercial License?

No. Commercial drivers should be particularly cautious about plea agreements. Under Utah Code § 53-3-414(13), a guilty or no-contest plea held in abeyance for a disqualifying offense can still trigger the required CDL sanction. The statute specifically addresses situations in which the charge is later reduced or dismissed under the plea in abeyance agreement.

For a CDL holder, the ordinary advantages of a plea in abeyance may not prevent the licensing consequences that follow from the underlying disqualifying offense. Federal law also defines conviction broadly for commercial licensing purposes. Under 49 C.F.R. § 383.5, a conviction can include accepted guilty or no-contest pleas and certain dispositions in which the penalty is suspended or probated.

Accordingly, a commercial driver should not assume that a deferred disposition, reduced fine, traffic-school arrangement, or eventual dismissal will necessarily protect the CDL.

11. What Happens When an Out-of-State Truck Driver Receives a Traffic Citation in Utah?

Utah routinely issues citations to commercial drivers licensed in other states. An out-of-state driver's case ordinarily proceeds under Utah law in the court with jurisdiction over the citation. However, the driver's home state remains responsible for the driver's commercial license and associated licensing record.

Utah Code § 53-3-414(10) includes reporting requirements concerning commercial driving disqualifications and the Commercial Driver's License Information System (CDLIS). The federal notification requirements in 49 C.F.R. § 383.31 also address convictions for traffic-control violations and generally require qualifying CDL drivers to notify their employers within 30 days. Notification to the licensing jurisdiction is governed by the regulation and applicable interstate reporting provisions.

Thus, a driver licensed in Texas who receives a serious speeding conviction in Utah should not assume the conviction will remain a Utah-only matter. It may become part of the driver's commercial driving history and affect later disqualification determinations.

12. Why Commercial Drivers Should Take a Utah Traffic Citation Seriously

Ordinary motorists often evaluate a traffic ticket by looking at the fine, insurance consequences, and driver's-license points. Commercial drivers must consider additional questions:

• Was the offense classified as a serious traffic violation or major offense under federal regulations?
• Was the driver operating a CMV?
• Does the driver have previous qualifying violations within the applicable three-year period?
• Would a conviction cause commercial driving disqualification?
• Does the driver's home state have additional administrative consequences?

These questions should be addressed before a CDL holder enters a plea or pays a citation. Payment of a traffic citation may constitute a conviction for federal CDL purposes. A driver should not assume that paying a relatively inexpensive Utah traffic ticket is harmless simply because no court appearance is required.

A Utah traffic citation can carry consequences beyond the court-imposed fine. For CDL holders, the important question is often whether a conviction will jeopardize the right to continue driving commercially. Commercial drivers who receive Utah traffic citations should have the applicable Utah statute, federal CDL classification, driving history, and potential licensing consequences evaluated before resolving the case.
