Key Takeaways
Utah recognizes three types of commercial driver's licenses: Class A, Class B, and Class C. Which one a driver holds depends on vehicle weight ratings, passenger counts, and the cargo being hauled. Those same details also determine whether a driver was legally authorized to operate the vehicle at all and whether a carrier should have assigned it.
If a heavy truck or bus has injured you, the class and codes printed on that driver's record can matter as much as the crash report itself. At Lance Bingham, we request licensing documents early when we evaluate a Salt Lake City commercial vehicle claim.

A commercial motor vehicle is not defined by size alone. Utah looks at gross vehicle weight rating, meaning the maximum loaded weight the manufacturer assigns to a vehicle, and gross combination weight rating, which covers a power unit together with everything it tows. Those ratings, rather than the actual load on any given day, set the licensing requirement.
Utah Code Section 53-3-412 sets out the three classifications, and each authorizes a different range of equipment. Federal commercial driver standards in 49 CFR Part 383 sit underneath the state rules, which is why these classes look similar from state to state.
A Class A license covers any combination of vehicles with a gross vehicle weight rating of 26,001 pounds or more, when the towed unit rates above 10,000 pounds. Tractor-trailers, tankers pulled behind a sleeper cab, and flatbed combinations all fall in this group. Class A is the broadest classification, and with the right endorsements, a Class A holder may operate much of the equipment covered by the other two classes.
That reach is one reason Class A is standard for long-haul freight running Interstate 15 and Interstate 80. It also means a single licensing error can involve the heaviest equipment sharing the road with passenger cars.
A Class B license covers a single motor vehicle rated at 26,001 pounds or more, including that vehicle when towing a unit rated at 10,000 pounds or less. Dump trucks, transit buses, box trucks, and refuse trucks are common examples on Utah roads. A Class B holder may not pull a heavy trailer, and that towing limit is the line separating this classification from Class A.
Many Class B vehicles never leave city streets, which places them near pedestrians, cyclists, and stopped traffic all day. Weight still does the damage in a collision, even at lower speeds.
A Class C commercial license covers a vehicle that falls below the Class A and Class B weight thresholds but carries people or dangerous cargo. It applies when the vehicle is designed to transport 16 or more occupants, including the driver, operates as a school bus rated under 26,001 pounds, or hauls hazardous materials requiring placards. Drivers often confuse this classification with a non-CDL Class C license, which is the ordinary license most Utah residents carry.
The distinction matters after a collision involving a shuttle van or a delivery truck carrying chemicals. A vehicle that looks ordinary from the outside may still have required a commercial license and a specific endorsement.
Classification is only the starting point. Endorsements expand what a driver may haul or carry, and each requires a separate knowledge test before the Driver License Division adds it to a license. Several endorsement codes appear on Utah commercial licenses under Utah Code Section 53-3-412:
A driver hauling placarded chemicals without an H endorsement is operating outside the scope of the license, regardless of the vehicle’s weight.
Endorsements also reveal something about the work a driver was hired to perform. A carrier assigning a tanker route to someone without an N endorsement has stepped outside the licensing system that state and federal rules built.
Restrictions work in the opposite direction and narrow what a driver may operate. An L restriction bars operation of a vehicle with air brakes, a K restriction limits the driver to routes inside the state, and an O restriction bars tractor-trailer combinations. A Z restriction applies to vehicles without fully equipped air brakes, and a V restriction signals a federal medical variance.
Most restrictions reflect the equipment used during the skills test. A driver who tested in a vehicle without air brakes carries the L restriction until testing again in properly equipped equipment.


Utah does not hand a commercial license to a new applicant directly. The process runs through a commercial driver instruction permit, and Utah Code Section 53-3-408 sets the qualifications for that permit. A few steps stand between an applicant and a Utah commercial license:
Applicants under 21 may operate only within Utah and cannot add hazardous materials, passenger, or school bus endorsements, according to the Utah Driver License Division. Medical certification is not a one-time formality either, and drivers must keep the self-certification on file with the division current.
Each step exists because commercial equipment forgives very little. A carrier that waives an applicant past any of them assumes a risk that falls on other people using the same highways.
Licensing looks like paperwork until a collision happens. When a truck or bus injures someone, our team at Lance Bingham looks at whether the driver held the correct class, carried the required endorsements, and stayed inside every restriction. A licensing gap rarely causes a crash by itself, but it often points toward a company that put an unqualified driver behind the wheel.
Motor carriers are the parties with a duty to check. They hire, train, assign equipment, and hold the insurance that responds when something goes wrong.
A carrier that hands a Class A rig to a driver holding only a Class B license has made a decision, not a clerical error. Our attorneys examine hiring files, road test records, and dispatch assignments to understand what the company knew before that driver left the yard.
Claims like these run against the company and not the driver alone. For-hire carriers operating in interstate commerce with vehicles rated above 10,000 pounds must carry at least $750,000 in public liability coverage under 49 CFR Section 387.9.
Evidence sits inside files the carrier controls, which is why timing matters so much. We request the driver qualification file, the commercial license abstract, endorsement history, medical certificates, and training records before routine retention periods run out.
Black box data and electronic logging records can also show whether a driver was operating equipment the license never authorized. If a commercial vehicle injured you in Salt Lake City, call 801-383-2922 and we can begin requesting those records.
Licensing rules answer one question. Utah's injury statutes answer the rest, shaping what an injured person may recover and how much time they have to act. Several rules carry real weight in these claims:
These rules interact with one another, and a delay on any single point can quietly limit the others.
Insurance carriers know this framework well and often move faster than the people negotiating against them. Understanding how the deadlines and fault rules apply to your own facts changes what a reasonable resolution actually looks like.
No. A Class B license does not authorize a combination vehicle with a towed unit rated above 10,000 pounds, which is exactly what a tractor-trailer requires.
The L restriction bars that driver from operating a commercial vehicle equipped with air brakes. It usually appears because the driver tested in a vehicle without them.
Potentially, yes. We examine whether the company verified the license class, endorsements, and restrictions before assigning that vehicle to that driver.
Most Utah injury claims carry a four-year filing deadline, though shorter deadlines apply in some situations. We recommend confirming the deadline that fits your facts early.
Yes. Utah prohibits operating a commercial motor vehicle at a .04 blood or breath alcohol concentration or greater, which sits below the general threshold.


If a commercial truck or bus injured you, the license class and endorsement codes on that driver's record deserve a close look.
At Lance Bingham, attorneys Dustin Lance and Cole Bingham handle commercial vehicle claims for people throughout Salt Lake City and the surrounding communities. Our team requests driver qualification files, licensing records, and carrier documents. We evaluate how the types of commercial driver's licenses involved in a crash affect who bears responsibility for it.
Records disappear on retention schedules that favor the companies holding them. Starting early gives us more of the file to work with and gives you a clearer picture of the options available in your situation. Waiting rarely improves either one.
