Colorado CDL Traffic Lawyer

If you are reading this article, chances are you hold a commercial driver’s license and already understand how important your driving record and CDL are to your livelihood. You may live and work in Colorado, or you may be an out-of-state commercial driver who received a traffic ticket or criminal traffic charge while traveling through Colorado. Either way, a Colorado traffic case can mean much more to a CDL holder than simply paying a fine or accumulating points on a driver’s license.

Commercial drivers face an additional layer of federal regulations that can affect what happens to their CDL after a conviction. Do you know whether your charge qualifies as a major offense or a serious traffic violation under federal law? Could a conviction result in the disqualification of your CDL? Does it matter whether you were driving a commercial motor vehicle or your personal vehicle when the violation occurred? And how might the federal prohibition against “masking” CDL convictions affect the plea agreement that a Colorado prosecutor is willing—or legally permitted—to offer?

The answers are particularly important in Colorado because the treatment of CDL traffic cases can vary significantly from one jurisdiction to another. Some prosecutors and courts have restrictive policies concerning plea agreements for CDL holders, while others may permit greater flexibility depending upon the charge and circumstances of the case. A reduction in Colorado points also does not necessarily answer the more important question of how a particular conviction may affect your commercial driving privileges.

This guide explains the federal CDL disqualification rules, serious traffic violations, masking requirements, and the practical issues involved in defending a Colorado CDL case. It also addresses some of the charges I regularly encounter when representing commercial drivers, including DUI and DWAI, altered or falsified logbooks and records, failure to comply with minimum safety standards, careless driving involving accidents, reckless driving, and speeding violations. The goal is to help you understand not only the charge you are facing, but also what it may mean for your CDL and your ability to continue driving for a living.

CDL Disqualifications and Serious Traffic Violations

For a CDL holder, the number of points assessed under Colorado law is only part of the equation. Federal regulations impose separate rules that can affect a commercial driver’s ability to operate a CMV. Under 49 C.F.R. § 383.51, CDL disqualifications are organized into several categories, including major offenses and serious traffic violations. The potential consequences depend on the particular offense, the driver’s prior record, and, in some circumstances, whether the violation occurred while driving a commercial or non-commercial motor vehicle. Importantly, certain major offenses and serious traffic violations can affect a CDL even when the driver was operating a personal vehicle rather than a CMV.

Major CDL Offenses

Federal law identifies certain violations as major offenses that can result in substantial periods of CDL disqualification. These include driving under the influence of alcohol or a controlled substance, having an alcohol concentration of .04 or greater while operating a CMV, refusing a required alcohol test, leaving the scene of an accident, using a vehicle to commit certain felonies, driving a CMV while disqualified under specified circumstances, and causing a fatality through the negligent operation of a CMV.

For many major offenses, a first conviction results in a one-year disqualification from operating a commercial motor vehicle. The disqualification generally increases to three years when the qualifying offense occurs while operating a CMV transporting hazardous materials. A second conviction arising from a separate incident involving certain major offenses can result in a lifetime CDL disqualification.

One particularly important point is that some major offenses do not have to occur while driving a commercial vehicle. For example, a CDL holder convicted of driving under the influence of alcohol under state law can face a one-year CDL disqualification even if the offense occurred while driving a personal vehicle. By contrast, the separate federal provision concerning an alcohol concentration of .04 or greater applies specifically when the driver is operating a CMV. For CDL holders, determining the potential consequences therefore requires looking not only at the conviction itself, but also at the particular federal provision involved and the type of vehicle being driven.

Serious Traffic Violations

Federal CDL regulations also identify a separate category of serious traffic violations. These include speeding 15 mph or more over the posted speed limit, reckless driving, improper or erratic lane changes, following too closely, certain traffic violations arising in connection with a fatal accident, operating a CMV without the required CDL or proper class or endorsements, and certain texting or handheld mobile telephone violations while operating a CMV.

Unlike many major offenses, a single serious traffic violation does not ordinarily result in an immediate CDL disqualification. Instead, the federal regulations focus on multiple serious traffic violations arising from separate incidents within a three-year period. A second qualifying serious traffic violation within three years can result in a 60-day disqualification, while a third qualifying violation within that period can result in a 120-day disqualification.

This makes a driver’s existing record particularly important when evaluating a new CDL traffic case. A speeding ticket for 15 mph over the limit or a reckless driving charge may not, standing alone, result in an immediate CDL disqualification, but the consequences can be very different for a driver who already has a qualifying serious traffic violation within the applicable three-year period.

Common Colorado CDL Traffic and Criminal Charges

Commercial drivers in Colorado can face much more than ordinary speeding tickets. Some cases involve traditional moving violations, while others arise from roadside commercial vehicle inspections, hours-of-service requirements, vehicle safety regulations, or allegations involving required records and logbooks. Depending on the charge, a commercial driver may be facing a traffic infraction, a criminal traffic offense, potential CDL consequences, or a combination of these concerns.

Some Colorado commercial vehicle violations are criminal offenses. Colorado law authorizes the Colorado State Patrol to adopt commercial vehicle safety rules addressing matters that include driver qualifications, hours of service, vehicle equipment, inspections, repairs, maintenance, and other safety requirements. A violation of a rule adopted under C.R.S. § 42-4-235 can constitute a class 2 misdemeanor traffic offense. Commercial drivers should therefore not assume that a citation arising from a roadside inspection or commercial vehicle regulation is simply a payable traffic ticket.

Commercial Vehicle Safety and Hours-of-Service Violations

Colorado’s commercial vehicle laws incorporate a broad range of safety requirements governing the operation of commercial vehicles. C.R.S. § 42-4-235 authorizes the Colorado State Patrol to adopt rules addressing matters that include driver qualifications, vehicle equipment, hours of service, inspections, repairs and maintenance, crash reporting, and other commercial vehicle safety requirements. A violation of a rule adopted under this statute can constitute a class 2 misdemeanor traffic offense. 

These provisions can result in charges that may look very different from the traffic offenses most drivers are accustomed to seeing. Commercial drivers may encounter citations involving hours-of-service violations, inaccurate or falsified records of duty status or logbooks, vehicle equipment and maintenance requirements, or violations discovered during a roadside commercial vehicle inspection. The particular federal regulation underlying the charge can therefore be just as important as the Colorado statute listed on the summons.

Hours-of-service rules are designed to limit how long commercial drivers may drive and remain on duty. For example, FMCSA regulations generally limit a property-carrying driver to 11 hours of driving after 10 consecutive hours off duty, prohibit driving beyond the 14th consecutive hour after coming on duty, require a qualifying 30-minute break after eight cumulative hours of driving, and impose 60/70-hour limits over seven/eight consecutive days. There are also important exceptions and special rules, including provisions concerning sleeper berths, adverse driving conditions, and certain short-haul operations. 

A citation involving an allegedly false or altered logbook or electronic record deserves particularly careful review. The issue is not simply how many hours the driver actually drove. The underlying records, electronic logging data, the particular regulation cited, and any applicable exception may all be important in determining what the prosecution must prove and what defenses or resolutions may be available.

Failure to Obtain Port of Entry Clearance — C.R.S. § 42-8-105

Colorado law requires certain vehicles to obtain clearance from the Colorado State Patrol or a port of entry weigh station before operating on Colorado highways. The requirement includes vehicles or combinations of vehicles with a manufacturer’s gross vehicle weight rating or gross combination weight rating of 26,001 pounds or more, as well as certain other vehicles identified by statute. 

The clearance requirements can be more extensive than simply stopping at a weigh station located directly on the driver’s route. The statute provides for obtaining clearance at the first port of entry weigh station located within five road miles of the route the driver would normally follow. It also requires covered owners or operators, absent a previously secured clearance or applicable special permit, to seek out a port of entry weigh station even when it is not located on the route being traveled. In addition, clearance must be verified at each port of entry weigh station located along the normal route from the point of departure to the destination.  

Whether a driver violated the port of entry requirements can therefore depend upon the vehicle involved, its weight rating, the route being traveled, the location of the port of entry, and whether the driver had previously obtained a valid clearance or special permit. A driver cited for failing to obtain port of entry clearance should not simply assume that the violation is an ordinary weigh-station ticket without first reviewing the specific charge and circumstances.

Driving a Commercial Motor Vehicle Without a CDL — C.R.S. § 42-2-404

Colorado law generally prohibits a person from operating a commercial motor vehicle on Colorado highways unless the driver has been issued and is in immediate possession of a commercial driver’s license. A violation is ordinarily a class 1 misdemeanor traffic offense, making this considerably more serious than an ordinary traffic infraction.  

The statute, however, contains an important provision for a driver who actually has a valid CDL. If the driver presents a valid commercial driver’s license to the court within 30 days after the violation or at the driver’s first scheduled court appearance, the offense, if there is a conviction, is reduced to a class A traffic infraction. 

This distinction can be particularly important when the issue is possession or proof of a valid CDL rather than whether the driver was legally qualified to operate the commercial vehicle in the first place. A driver cited under C.R.S. § 42-2-404 should therefore determine exactly why the citation was issued and whether the statutory provision allowing reduction to a traffic infraction applies.

DUI and DWAI Charges Involving CDL Holders

A commercial driver facing a DUI or DWAI charge in Colorado may have significantly more at stake than the consequences associated with an ordinary driver’s license. Importantly, the frequently cited .04 BAC standard for commercial drivers does not mean that a CDL holder is protected from DUI or DWAI consequences whenever the driver’s BAC is below .04.

Colorado’s ordinary DUI and DWAI laws continue to apply. DUI includes driving when alcohol, drugs, or a combination of both renders a person substantially incapable of exercising clear judgment, sufficient physical control, or due care. DWAI requires a lower level of impairment—impairment to the “slightest degree” so that the person is less able than ordinarily to exercise those abilities. Colorado also separately prohibits DUI per se when a driver’s BAC is .08 or higher at the time of driving or within two hours afterward.  

Commercial drivers have an additional concern when actually operating a commercial motor vehicle. Colorado defines “Excess BAC CDL” as driving a commercial motor vehicle with a BAC of .04 or more, and the statute provides for revocation of the commercial driving privilege for the disqualification period established under federal law.  

The distinction between holding a CDL and driving a commercial motor vehicle at the time of the incident is therefore important. A CDL holder arrested for DUI or DWAI while driving a personal vehicle can still face serious consequences to the commercial driving privilege, even though the special .04 Excess BAC CDL provision applies to driving a commercial motor vehicle.

Refusal can carry additional consequences when the driver is operating a commercial motor vehicle. Under Colorado’s expressed consent law, an officer requesting a chemical test from the driver of a commercial motor vehicle must warn the driver that refusal will result in a 24-hour out-of-service order and a one-year revocation of the privilege to operate a commercial motor vehicle

Careless Driving and Commercial Vehicle Accidents

Careless driving is another common charge involving commercial drivers in Colorado, particularly when a traffic citation arises from a crash. Under C.R.S. § 42-4-1402, careless driving generally involves operating a vehicle in a careless and imprudent manner, without due regard for the road, traffic, and other attendant circumstances. A basic careless driving charge is a class 2 misdemeanor traffic offense, while careless driving resulting in bodily injury, serious bodily injury, or death is a class 1 misdemeanor traffic offense.

For commercial drivers, careless driving charges can arise from a wide variety of crashes. These include ordinary highway and city traffic crashes, collisions involving lane changes or following distance, and loss-of-control crashes caused by snow, ice, wind, or other difficult driving conditions. A tractor-trailer that slides off an icy roadway or jackknifes on I-70, for example, may result in a careless driving citation even though the crash occurred during challenging weather or road conditions.

I also frequently see these cases arise from relatively low-speed incidents involving tractor-trailers at truck stops, loading areas, parking lots, and similar locations. Something as routine as backing a truck into or out of a parking space can result in contact with another vehicle or property and a careless driving charge.

There is another wrinkle that commercial drivers should not overlook. If the driver leaves after a crash without realizing that contact occurred—or believing that no reportable damage resulted—the incident can potentially lead to an allegation of leaving the scene of a crash in addition to the underlying traffic charge. What began as a minor backing incident at a truck stop can therefore become considerably more serious.

For a CDL holder, the analysis should not stop with the immediate fine or points associated with the ticket. The charge, the circumstances surrounding the crash, the driver’s record, and the potential effect of any conviction on the driver’s commercial driving privileges and employment should all be considered before resolving the case.

Reckless Driving and CDL Consequences

Reckless driving can present particularly serious consequences for a commercial driver. Under C.R.S. § 42-4-1401, a person commits reckless driving by operating a vehicle in a manner that demonstrates a wanton or willful disregard for the safety of persons or property. Reckless driving is a class 2 misdemeanor traffic offense in Colorado. 

Reckless driving requires more than ordinary carelessness. Colorado courts have recognized that careless and reckless driving both involve a disregard for safety, but reckless driving requires a substantially more culpable degree of conduct. The distinction can therefore be important when reviewing the driving behavior alleged by the officer, dash-camera or body-worn-camera footage, witness accounts, accident evidence, and the circumstances surrounding the citation. 

For a CDL holder, however, the consequences do not end with the Colorado criminal traffic case. As discussed above, reckless driving is also classified as a “serious traffic violation” under federal CDL regulations. A conviction can therefore become particularly significant when combined with another serious traffic violation occurring within the applicable three-year period.

This makes the precise disposition of a reckless driving charge especially important for a commercial driver. A plea that may appear favorable when viewed only in terms of Colorado points or the immediate criminal case may still have separate consequences for the driver’s CDL. Before resolving the case, the driver should consider both the Colorado disposition and how that disposition will be treated under the federal commercial-driver rules.

Speeding Violations and CDL Holders

Speeding tickets can have consequences for a commercial driver that extend well beyond the fine imposed by the court. Colorado assigns points based upon the amount by which the driver exceeded the applicable speed: 5 to 9 mph over is generally 1 point, 10 to 19 mph over is 4 points, 20 to 39 mph over is 6 points, and 40 mph or more over is 12 points. 

Higher-speed violations can also become criminal traffic cases. Under C.R.S. § 42-4-1101, driving 25 mph or more over the reasonable and prudent speed or maximum lawful speed is generally a class 2 misdemeanor traffic offense. If the violation occurs within a designated maintenance, repair, or construction zone, it is a class 1 misdemeanor traffic offense. 

For CDL holders, however, another threshold is especially important: 15 mph or more over the speed limit can qualify as a “serious traffic violation” under federal commercial-driver regulations. As discussed above, multiple serious traffic violations within the applicable three-year period can result in disqualification of the commercial driving privilege. A commercial driver should therefore not evaluate a speeding case solely by looking at the number of Colorado points assigned to the ticket.

Colorado also enacted significant new point penalties for certain speeding convictions effective August 12, 2026. The new law applies to violations involving driving 20 mph or more over the reasonable and prudent speed, or driving in excess of Colorado’s maximum lawful speed of 75 mph. For a second qualifying violation within 12 months, the Department of Revenue must assess 2 additional points; for a third or subsequent qualifying violation within 24 months, 4 additional points; and for a fifth or subsequent qualifying violation within five years, 8 additional points. Separately, driving 100 mph or greater results in 4 additional points beyond the points otherwise assessed for the speeding conviction.

These different thresholds can make the precise resolution of a speeding case particularly important for a CDL holder. A reduction in the alleged speed may affect the Colorado point assessment, whether the offense remains a criminal traffic charge, and whether the resulting conviction falls within the federal definition of a serious traffic violation. For that reason, the number written in the “alleged speed” and “speed limit” boxes on a commercial driver’s summons can matter considerably more than it might initially appear.

Leaving the Scene of a Crash and CDL Consequences

Leaving the scene of a crash can create particularly serious problems for a commercial driver. Colorado’s traffic statutes now use the term “crash” in provisions that were historically described in terms of a motor vehicle “accident.” Colorado law imposes different duties depending upon whether a crash involves property damage, injury, serious bodily injury, or death. In general, a driver involved in a crash must stop, provide the required identifying and vehicle information, render reasonable assistance when someone is injured, and report a crash involving injury, death, or property damage to law enforcement.  

The potential criminal penalties increase dramatically when someone is injured. Leaving the scene of a crash involving injury is a class 1 misdemeanor traffic offense; leaving the scene involving serious bodily injury is a class 4 felony; and leaving the scene involving death is a class 3 felony. A conviction under the injury-or-death statute also results in revocation of the driver’s license. A property-damage-only violation under C.R.S. § 42-4-1602 is a class 2 misdemeanor traffic offense. 

For CDL holders, there is an additional and potentially career-threatening consequence. Colorado’s mandatory revocation statute specifically addresses a driver found to have knowingly and willfully left the scene of a crash involving a commercial motor vehicle driven by that person. In addition, leaving the scene is treated as a major disqualifying offense under the federal CDL rules. A commercial driver therefore needs to consider not only the criminal charge and ordinary driver’s-license consequences, but also the separate effect on the commercial driving privilege. 

Colorado law also provides an administrative license-suspension process for certain leaving-the-scene allegations involving serious bodily injury or death. Importantly, DMV action does not require the driver first to be convicted in the criminal case. The Department may impose a one-year suspension based upon its own administrative determination under a preponderance-of-the-evidence standard, subject to the driver’s right to request a hearing. The deadline to request that hearing can be extremely short.  

A leaving-the-scene allegation can also arise from a surprisingly minor event. As discussed above, a commercial driver backing a tractor-trailer at a truck stop or loading area may make contact with another vehicle without immediately realizing it. Whether the driver knew a crash occurred, what happened afterward, the extent of any damage or injury, and what the driver did to comply with Colorado’s stop, information, aid, and reporting requirements can all become important issues in defending the case.

How a Colorado Traffic Conviction Can Affect Your CDL

For a commercial driver, resolving the court case is only part of the analysis. A plea agreement that appears favorable when viewed solely in terms of fines or ordinary driver’s-license points may still have significant consequences for a CDL. Federal and Colorado law separately identify certain convictions as disqualifying offenses or serious traffic violations, and those consequences can depend upon the particular offense, the driver’s prior record, and whether the violation occurred while operating a commercial motor vehicle or a personal vehicle.

This is one reason CDL cases should be evaluated differently from an ordinary traffic ticket. Before accepting a plea agreement, a commercial driver should understand not only the immediate court consequences, but also whether the conviction will be reported to the licensing authority, whether it counts toward a CDL disqualification, and what effect it may have on the driver’s ability to continue working.

Federal CDL “Masking” Rules and Colorado Plea Agreements

CDL cases present an additional complication when negotiating a traffic charge: the federal prohibition against “masking” certain convictions. Under 49 C.F.R. § 384.226, states may not mask a conviction for a traffic-control violation committed by a CDL holder, or by a person required to hold a CDL, by preventing the conviction from appearing on the driver’s record. The rule also prohibits states from using diversion programs to keep such convictions off the record.

The masking rule does not mean that every CDL traffic charge must result in a conviction to the offense originally charged. Traffic cases may still involve legitimate factual and legal issues, and charges may be amended or dismissed when supported by the circumstances of the case. The federal rule does, however, limit the ability to resolve a case simply by making an otherwise reportable conviction disappear from the driver’s record.

This distinction is especially important because the particular offense of conviction matters under the federal CDL rules. For example, federal regulations identify reckless driving and speeding 15 mph or more above the posted limit as serious traffic violations. Multiple qualifying convictions arising from separate incidents within a three-year period can result in CDL disqualification. The goal in evaluating a proposed resolution therefore should not be limited to obtaining fewer Colorado points; it should include determining what the actual conviction will be and how that conviction may affect the driver’s commercial driving privilege. 

Colorado courts and prosecutors do not necessarily approach plea negotiations involving CDL holders in the same way. Some jurisdictions have restrictive policies concerning reductions of traffic charges for commercial drivers, while others evaluate possible resolutions based upon the facts, driving history, evidentiary issues, and circumstances of the individual case. No particular reduction or disposition can be assumed simply because the defendant holds a CDL.

Colorado Courts May Treat CDL Plea Bargaining Differently

Commercial drivers sometimes assume that there is a single statewide policy governing plea negotiations in CDL traffic cases. In practice, the approach can vary significantly from one Colorado jurisdiction to another. Some courts and prosecutors take a particularly restrictive approach to reducing traffic charges when the defendant holds a CDL, while others will consider an amended charge when the facts and circumstances support a different disposition.

The City of Thornton provides a useful example of the more restrictive approach. Its written advisement for CDL holders states that federal regulations prohibit masking traffic convictions and advises commercial drivers that they should expect a plea offer “to the charge as written.” Other Colorado jurisdictions may have their own policies or practices concerning commercial drivers and plea negotiations.

This means that the location of the case can matter. A resolution that may be considered in one Colorado court may not be available in another, even when the original charges appear similar. The prosecutor’s policies, the particular facts of the case, the driver’s record, the evidence supporting the charge, and the potential CDL consequences can all affect whether a negotiated resolution is possible.

For an out-of-state commercial driver, this can be especially important. A driver who receives a Colorado citation while passing through the state may have no familiarity with the particular court or prosecutor handling the case. Before simply paying a ticket or accepting an offered disposition, it is important to determine what the resulting Colorado conviction will be and what that conviction may mean for the driver’s CDL in the licensing state.

Why a Lower-Point Plea May Not Solve the CDL Problem

For an ordinary Colorado driver, reducing the number of points associated with a traffic conviction is often an important objective. For a CDL holder, however, the number of Colorado points is only part of the analysis. Federal commercial-driver rules focus on the offense of conviction and whether that offense falls within a category that can result in CDL disqualification.

For example, federal regulations classify speeding 15 mph or more above the regulated or posted speed limit as a serious traffic violation. Reckless driving is also specifically included. Multiple serious traffic violations arising from separate incidents within a three-year period can result in a 60-day or 120-day CDL disqualification, depending upon the driver’s record and the circumstances of the violations. 

As a result, a plea agreement should not be evaluated simply by comparing the points assigned to the original charge with the points assigned to the proposed disposition. A lower-point conviction may be beneficial, but the more important question for a commercial driver may be whether the specific offense of conviction carries a separate federal CDL consequence.

The reverse is also important: not every traffic conviction that carries Colorado points is automatically a federally defined serious traffic violation or major disqualifying offense. Colorado’s point system and the federal CDL disqualification rules serve different purposes and should be analyzed separately.

How I Approach a Colorado CDL Traffic Case

A commercial driver’s case should be evaluated with more than the immediate traffic charge in mind. My first step is to determine exactly what the driver is charged with, whether the driver was operating a commercial or personal vehicle, and what consequences a conviction could have under both Colorado law and the federal CDL regulations.

I also review the driver’s prior record because a conviction that might not independently result in CDL disqualification can become significantly more serious when combined with a prior qualifying offense. The timing and nature of earlier convictions can therefore be just as important as the charge in the current case.

The evidence matters as well. Depending upon the charge, that may include police reports, body-worn or dash-camera footage, accident reports and diagrams, witness statements, speed-measurement evidence, commercial vehicle inspection records, electronic logging information, or other records related to the alleged violation. The fact that a citation was issued does not necessarily mean that every element of the charged offense can be proven.

Finally, I consider the practices of the particular Colorado court and prosecutor handling the case and whether a negotiated resolution is realistically available. If a plea offer is made, I evaluate the proposed disposition not simply by its fine or Colorado point assessment, but also by the potential effect of the resulting conviction on the driver’s CDL.

For a commercial driver whose livelihood depends upon remaining behind the wheel, those issues should be considered before the case is resolved—not after the conviction has already been entered.

Frequently Asked Questions About Colorado CDL Traffic Cases
