Motor carrier classes by state
Wyoming put a weight in the definition of a private carrier and no weight at all in the definition of a carrier that hauls for compensation. Those two definitions sit in adjacent subparagraphs of the same section. Which one an operator falls under decides whether anything attaches at 26,000 pounds or whether everything attaches at the first paid load, and the answer for a for-hire light combination is the second one.
The parts of light-combination and expedited hauling that behave identically in every jurisdiction — the tight window, the mixed securement duty, the way one high-value load overruns a cargo limit written against an average one — belong to the class rather than to Wyoming, and they are set out on the hot shot trucking insurance page rather than repeated here.
What Wyoming contributes is a pair of definitions that pull against each other inside W.S. 31-18-101(a). One of them, the definition of “commercial vehicle,” carries a 26,001 pound intrastate figure that an operator will find quoted in almost every summary of this state. The other, the definition of “contract motor carrier,” carries no figure at all, and it is the definition the authority and insurance provisions are actually written to.
It is worth being precise about the absence too. No Wyoming statute or rule read for this page uses the words this trade uses for itself. There is no defined term for it, no dedicated class of authority, and no separate schedule. Wyoming reaches the work the way it reaches every carrier: by asking whether property moves for compensation, and then by asking a series of questions about the equipment that are not all questions about weight.
Every figure below is attributed to the instrument that sets it. Where a figure lives in a WYDOT rule chapter that could not be retrieved on the date this page was verified, this page says so rather than reproducing a number it could not read.
Hauling for money inside Wyoming on a combination that never approaches 26,000 pounds? The chapter that decides whether you may run at all does not ask what the rig weighs — it asks whether you were paid.
Tell us whether you hold a Wyoming letter of authority, what the power unit’s axle count is, and what registered gross weight appears on the registration. Those three answers change which subparagraph you are being read under.
The decisive contrast in Wyoming is two subparagraphs apart. W.S. 31-18-101(a)(x)(A) provides: “‘Contract motor carrier’ means any person engaged in the intrastate or interstate transportation of persons or property by motor vehicle on highways for compensation.” There is no rating in that sentence, no combination weight, and no equipment description of any kind. The whole of the trigger is transportation of property, by motor vehicle, on highways, for compensation.
Now read the neighboring definition. W.S. 31-18-101(a)(x)(D) provides that “‘Private motor carrier’ means any person engaged in business and operating a vehicle which has a gross vehicle weight, gross vehicle weight rating, gross combination weight or gross combination weight rating exceeding twenty-six thousand (26,000) pounds operating intrastate,” with a different figure stated for interstate operation, “who, without compensation, transports over highways his employees or property of which the person is the owner, lessee or bailee, used in the furtherance of any commercial enterprise.”
The drafting is deliberate on its face. Wyoming knew how to write a weight into a carrier definition, wrote one into the definition of the operator who is not being paid, and declined to write one into the definition of the operator who is. An operator whose rig is nowhere near 26,000 pounds and who reasons from the private-carrier figure has read the definition that describes somebody else’s operation.
The word that separates them is “compensation,” and Wyoming defines that too. W.S. 31-18-101(a)(iv): “‘Compensation’ means money or other recompense given, either directly or indirectly, for the transportation of persons or property by a motor carrier.” The phrase “either directly or indirectly” is doing work. A haul that is not separately invoiced, but is priced into a job the operator is being paid for, is not obviously outside a definition drawn that way.
There is one further oddity in the chapeau above both of them that is worth naming rather than tidying away, because a reader who notices it will assume the page has misquoted. W.S. 31-18-101(a)(x) opens: “‘Motor carrier’ or ‘carrier’ means a contract, private or interstate commercial vehicle operating on highways as hereafter defined.” The chapeau defines a class of person as a vehicle, and then the subparagraphs beneath it define each member as a person. The subparagraphs are the operative text and this page reads them as written; the chapeau is reproduced here exactly so that nobody has to wonder whether it was cleaned up.
The 26,001 pound figure that dominates secondary accounts of this state is real, and it sits in a different definition doing a different job. W.S. 31-18-101(a)(iii) defines “commercial vehicle” as “any vehicle or vehicle combination used, designed or maintained for transportation of persons for hire, compensation or profit, or designed or used primarily for the transportation of property for gain or profit,” and then says the term “shall include, but not be limited to” a list. Subparagraph (E) is the intrastate list, and it runs to seven limbs.
Limb (I) is the familiar one: any vehicle transporting persons or property with a gross vehicle weight rating, gross combination weight rating, gross vehicle weight or gross combination weight of twenty-six thousand one (26,001) pounds or more. Limbs (II) and (III) are passenger counts, eight or more for compensation and sixteen or more without. Limb (IV) is a vehicle requiring a hazardous materials placard.
Then the list stops being about scale weight. Limb (V) reaches “a power unit having two (2) axles and a gross vehicle weight or registered gross vehicle weight exceeding twenty-six thousand (26,000) pounds.” Limb (VI) reaches “a power unit having three (3) or more axles regardless of weight.” Limb (VII) reaches a vehicle “used in combination when the weight of such combination exceeds twenty-six thousand (26,000) pounds of gross vehicle weight.”
Limb (VI) is the one that will surprise an operator running a heavier chassis. It contains no weight condition whatsoever. A three-axle power unit is inside the definition on the strength of its axle count alone, and the fact that it may be far below any of the pound figures in the neighboring limbs is irrelevant to limb (VI) by its own terms. An operator who moves from a two-axle truck to a dually-and-tag configuration has changed which limb they are read under without changing what the rig can carry.
And the chapeau above the list is open. “Shall include, but not be limited to” is not a closing formula; it is an express statement that the seven limbs are examples of the general definition rather than the whole of it. The general definition is about vehicles used, designed or maintained for the transportation of property for gain or profit. That is a purpose test, and a rig that fails all seven enumerated limbs has still not been shown to sit outside the sentence that the limbs illustrate.
Limb (V) does something no other limb in the intrastate list does: it accepts either “gross vehicle weight or registered gross vehicle weight.” One of those is a fact about the truck. The other is a fact about the paperwork.
Registered gross vehicle weight is a declared figure. An operator picks a registration weight when the plate is bought, usually with an eye on what the rig might reasonably be asked to haul and on what the registration costs at each step. It is entirely possible to register at a weight the combination has never actually reached, for the ordinary and sensible reason that nobody wants to be caught a few hundred pounds over a declared limit on the one load that runs heavy.
The consequence in Wyoming is that a two-axle power unit can enter the “commercial vehicle” definition by a decision made at a licensing counter rather than by anything that happens on a scale. A conservative registration choice is a safety-classification choice as well, and the two decisions are usually made by different people at different times without either one knowing about the other.
This is one of the few places where a purely administrative act moves a rig across a regulatory line, and it is worth checking on any Wyoming account before anyone reasons from the scale ticket. The declared weight on the registration is evidence of the classification in a way that the load on the deck is not.
Send the authority status, the power unit’s axle count, and the registered gross weight printed on the registration. In Wyoming those three answers place the operation under a definition before any coverage question is reached.
The insurance obligation is statutory and its text is unusually direct about what it covers. W.S. 31-18-209(f) provides that “the department shall require intrastate contract carriers to deposit with it, policies of insurance companies which are either authorized to do business in Wyoming or are lawfully able to transact insurance without a certificate of authority pursuant to title 26 of the Wyoming statutes as determined by the insurance commissioner of this state or other adequate security for cargo, public liability and property damage insurance for the protection of the public generally.”
Three things in that sentence matter more than any dollar figure. The duty is owed by intrastate contract carriers — the class defined without a weight, which is the point of the section above. Cargo is named alongside public liability and property damage rather than being left to the market. And the insurer has to be admitted in Wyoming, or else specifically found by the insurance commissioner to be lawfully able to transact insurance without a certificate of authority; a surplus-lines placement is not simply interchangeable with an admitted one for the purpose of this deposit.
The same subsection makes the filing continuous and makes its lapse operational rather than administrative. The policy, bond or proof of other security “shall be continuous and remain in full force and effect unless and until cancelled on not less than thirty (30) days written notice to the department, the notice to commence to run from the date it is received at the office of the department.” And then: “The cancellation filed with the department shall, upon its effective date, suspend the operating authority of the affected carrier and no operations shall be conducted on any highway until the insurance, bond or other adequate security, in the form and amount required, becomes effective and is approved by the department.”
That is a hard stop, written into the statute, with an approval step at the end of it. The truck does not resume when the new policy incepts; it resumes when the department has the replacement security in the required form and amount and has approved it. A gap that would be a paperwork problem in another state is a parked fleet here.
The subsection carries one more duty that operators of light combinations routinely underestimate. The department “shall require contract motor carriers to use and carry in their motor vehicles at all times uniform bills of lading, showing all property currently being transported, to deliver copies to both consignor and consignee and to retain a copy for the inspection of the department and the state highway patrol.” Work sold on availability, moved on a text message and settled afterwards is exactly the pattern this sentence is inconsistent with.
What this page does not state is the dollar amount. The statute does not contain one; W.S. 31-18-209(f) says “in the form and amount required” and leaves the amount to the department’s rules. Those rules are a WYDOT rule chapter, and on the date this page was verified that chapter could not be retrieved — see the section on the two chapters below. A number that could not be read at source is not published here.
Wyoming defines the instrument itself. W.S. 31-18-101(a)(ii): “‘Authority’ means a document issued under this act by the department, granting intrastate authority to a person to operate a motor vehicle as a motor carrier transporting persons or property.” The issuing body is the Wyoming Department of Transportation, named at W.S. 31-18-101(a)(v) as the department of transportation.
W.S. 31-18-209(a) provides that “the department shall issue authority to qualified motor carriers. The authority shall remain valid and in effect unless revoked or suspended by the department for good cause, such as a violation of this act, or cancelled at the request of the authority holder.” There is no renewal cycle in that sentence. The authority does not expire on a calendar; it persists until something ends it.
The application requirements are short. W.S. 31-18-209(b) requires the application to be in writing and verified, and to contain the applicant’s name and address, a statement of the nature of the transportation service proposed, any additional information the department deems necessary, and a filing fee of fifty dollars ($50.00). The replacement fee for a letter of authority is ten dollars ($10.00). Several of the paragraphs that once sat in that list were repealed by Laws 1998, ch. 46, § 2, and the numbering still shows the gaps.
The carrying obligation is at W.S. 31-18-301(b): “No motor carrier that is required to have authority shall operate on the highways without a copy of the current authority carried in each power unit.” Subsection (c) makes it producible on demand to field investigators, the highway patrol or authorized port-of-entry personnel, and gives them the power to compel a stop for inspection. It also contains the bypass provision — a vehicle that is properly registered, has a proper fuel license, valid authority and is legal in size and weight may, on the department’s approval, be authorized to bypass a port of entry.
Read that bypass sentence against the classification questions above. Every one of its four conditions is a condition an operator can be wrong about without knowing it, and the one most likely to be wrong on a light combination is “valid authority” — because the operator concluded from a weight figure that no authority was needed.
W.S. 31-18-103(a) disapplies four named sections — 31-18-104, 31-18-209, 31-18-301 and 31-18-304 — to a defined list. That is a meaningful set of sections to be exempted from: it is the department’s licensing duty, the authority and insurance section, the carry-and-produce section and the marking section, which is to say most of what this page has described.
The list itself does not reach commercial freight. Its first three paragraphs were repealed by Laws 2009, ch. 183, § 2 and appear only as numbered gaps. What survives is intrastate transportation by a farmer or rancher, or an employee exclusively in that service, of produce or commodities for the farmer’s own use to and from the farm or ranch; the exchange of intrastate transportation between farmers or ranchers in the immediate community; and further paragraphs in the same register.
Every surviving limb is defined by who owns the property and why it is moving, not by how much the rig weighs. There is no weight-based relief in the section at all. An operator hauling somebody else’s property for money is outside the exemption on the face of the first paragraph, and the absence of a weight limb is the point rather than an oversight — the section is drawn on character of use, and Wyoming had the drafting vocabulary for weights available two sections earlier and did not reach for it here.
This matters because the exemption list is where an operator would look for relief, and looking there and finding nothing is a result. The four sections it can switch off are the four sections that would otherwise apply in full.
Wyoming does not pin the federal safety text to an edition date in statute. W.S. 31-18-303(a) directs that “the department shall adopt rules and regulations prescribing the permissible operating time and other requirements of motor carrier drivers, equipment and the transportation of hazardous materials which are consistent with comparable regulations of the United States department of transportation.”
Subsection (c) then supplies the currency rule, and it is written as a default with an escape: “Unless exception is made by the department after public hearings held pursuant to the Wyoming Administrative Procedure Act, the rules of the department shall be current with rules adopted by the United States department of transportation, as now or hereafter amended.”
Two consequences follow. The first is that a federal amendment reaches Wyoming intrastate operation without a Wyoming rulemaking event, because the statute’s default is currency rather than a snapshot. There is no edition date to check and no “revised as of” clause to fall behind. The second is that any divergence has to have come through a public hearing under the state’s Administrative Procedure Act, which means a departure from the federal text is a thing with a record rather than a thing that quietly happened.
Subsection (b) carries a narrow public-utility emergency relief from driving-time regulations, conditioned on an emergency existing — defined as an occasion or instance that jeopardizes public health or safety or endangers property — and on the utility exercising due diligence in contacting state or local officials and documenting its efforts. Subsection (e) subjects intrastate for-hire passenger transportation in vehicles with an occupant capacity of seven or more but not more than fifteen to the hours-of-service requirements that apply to vehicles with capacities of fifteen or more.
Neither of those reaches a property-hauling light combination, and this page names them so that the shape of the section is visible: Wyoming legislated on hours in two specific directions, and general intrastate freight was not one of them.
Honesty about what could not be read is part of the answer here, because Wyoming keeps its operative detail in rule rather than in statute. The Wyoming Department of Transportation’s Motor Carrier program maintains a small set of current rule chapters, and two of them carry material this page would otherwise state: Chapter 1 (Motor Carriers), which hooks the federal safety regulations to the statutory definitions and carries a Wyoming-specific appendix, and Chapter 3 (Insurance Requirements), which fixes the amounts that W.S. 31-18-209(f) leaves to the department.
On the date this page was verified, the state’s rules host would not serve either chapter. The search landing page answered normally at rules.wyo.gov, but every request for a rule document returned a seventeen-byte body reading “No File Available,” with a session cookie and a referer as well as without, and the site’s own data endpoint answered “ERROR: Value cannot be null.”
So this page states the statutory obligation — that cargo, public liability and property damage security must be deposited, that it must be continuous, that its cancellation suspends the authority — and does not state the amounts. It also does not restate the appendix-level modifications the rule chapter is understood to contain. A figure that could not be read at source on the day of verification is not a figure this page is entitled to publish.
The practical guidance that follows is not a limitation of this page so much as a description of the state. An operator who wants the current Wyoming amounts should obtain them from the department directly rather than from any secondary summary, and should date the answer, because a rule chapter that is difficult to retrieve is also a rule chapter whose secondary copies are difficult to date.
There is no rate table for this class and no honest way to quote one from a page. What follows is the material an underwriter reads before producing a number, and in Wyoming the first item is not the truck.
Authority status comes first, because it decides which regime the account is in. An operator holding a Wyoming letter of authority is a contract motor carrier with a continuous deposit obligation and a statutory shut-off on cancellation. An operator who concluded from a weight figure that none of that applied is a different risk on paper and the same risk on the road, and the difference will surface at the first port of entry rather than at renewal.
Configuration is second, and specifically axle count and registered gross weight rather than what the rig scales at. Limb (VI) reads the axles. Limb (V) reads the registration. Neither reads the load. An account that has added a tag axle or bought a heavier plate has moved on the classification questions without moving on the operational ones.
Radius and terrain are third, and in Wyoming they are unusually consequential for reasons that have nothing to do with the code. Long empty distances between service points mean a breakdown is a long recovery, an out-of-service order is a long delay, and a driver’s day distributes differently than the same driver’s day in a dense state. The honest answer to a radius question is a distribution rather than a maximum, and the distribution is what gets priced.
Commodity is fourth and it moves cargo more than liability. Light-combination freight skews to high value per pound — components, controlled-temperature items, replacement parts bought at a premium precisely because something has stopped — and a cargo limit set against the average load fails against the load that generates the claim. Wyoming names cargo in the statutory deposit, which means the cargo question is a compliance question here as well as a coverage one.
Underneath all of it sits the contract stack. Whether the operation runs on its own authority or someone else’s, what a shipper agreement requires by way of additional-insured and primary-and-non-contributory wording, and whether a waiver of subrogation has been given, are terms that change the program without changing a single fact about the truck.
Some of the most useful facts about this state are absences, and an absence is only worth stating if the content that would contain it was actually read. The Legislature’s consolidated Title 31 was re-fetched for this page and hashes identically to the copy read in research; chapter 18, the Commercial Vehicles chapter, was read for the definitions, exemptions, authority, insurance, carrying and rulemaking sections named above.
Inside that chapter there is no defined term for this trade, no class of authority written for it, no separate insurance schedule keyed to it and no weight band drawn around it. Wyoming does not have a rule for this work, and no state read in the census does. The work is reached by the compensation trigger and by the equipment prongs, which were written for motor carriage in general.
There is also no dollar amount for the insurance deposit anywhere in the statute. That is not a gap in the reading; the statute delegates the amount and says so, and the delegation is what sends the question to a rule chapter this page could not retrieve. Stating the delegation and declining to state the number is the accurate report.
Finally, the exemption section contains no weight relief. That was established by reading W.S. 31-18-103(a) rather than by inferring it from the section heading, and it is the reason this page treats the binding question as a compensation question rather than a weight question throughout.
The state minimum is a licensing threshold. The program an operator actually needs is built from these lines:
We write hot shot and expedited hauling as a named class rather than as an exception to general trucking, and we read each account against the weight and authority regime of the state it operates in. For a Wyoming operator that means starting from the rating of the power unit and the trailer separately rather than from the combination, sizing cargo against the heaviest load actually carried rather than the average one, and treating the state line as a rating fact because a single crossing can change which driver file the operation owes.
If the operation also runs freight under separate authority, the Wyoming trucking insurance page covers the state’s broader motor carrier picture, and the hot shot trucking insurance page covers the class mechanics that apply wherever the operator runs.
Not on the definition the authority and insurance provisions are written to. W.S. 31-18-101(a)(x)(A) defines a contract motor carrier as any person engaged in the intrastate or interstate transportation of persons or property by motor vehicle on highways for compensation, with no weight element. The 26,001 pound figure that appears in most summaries of this state sits in the separate definition of “commercial vehicle” at W.S. 31-18-101(a)(iii), which does a different job.
Because one limb of the intrastate list has no weight condition. W.S. 31-18-101(a)(iii)(E)(VI) reaches “a power unit having three (3) or more axles regardless of weight.” The adjacent limb, (E)(V), reaches a two-axle power unit only if its gross or registered gross weight exceeds twenty-six thousand pounds. Adding an axle can move a rig across that line without changing what it hauls.
It matters, and it is the unusual feature of this state’s list. W.S. 31-18-101(a)(iii)(E)(V) accepts “gross vehicle weight or registered gross vehicle weight.” Registered gross weight is a figure declared when the plate is purchased, so a conservative registration choice can place a two-axle power unit inside the definition even if the combination has never reached that weight on a scale.
W.S. 31-18-209(f) requires the department to take a deposit of policies, or other adequate security, for cargo, public liability and property damage, from insurers authorized to do business in Wyoming or lawfully able to transact without a certificate of authority as determined by the insurance commissioner. The statute states no dollar amount; it leaves the amount to department rule. On the date this page was verified, the WYDOT rule chapter carrying those amounts could not be retrieved from the state’s rules host, so this page does not state them.
Operations stop. W.S. 31-18-209(f) provides that the cancellation filed with the department shall, upon its effective date, suspend the operating authority of the affected carrier, and that no operations shall be conducted on any highway until the insurance, bond or other adequate security, in the form and amount required, becomes effective and is approved by the department. Cancellation runs on not less than thirty days written notice, counted from receipt at the department’s office, and reinstatement requires departmental approval rather than merely a new policy.
Not on a calendar. W.S. 31-18-209(a) provides that the authority “shall remain valid and in effect unless revoked or suspended by the department for good cause, such as a violation of this act, or cancelled at the request of the authority holder.” W.S. 31-18-301(a) states the same result for authorities issued after April 1, 1989. The obligation that recurs is the carrying obligation at W.S. 31-18-301(b), which requires a copy of the current authority in each power unit.
No. W.S. 31-18-103(a) is the exemption section, and it disapplies W.S. 31-18-104, 31-18-209, 31-18-301 and 31-18-304 to a list drawn on character of use — farm and ranch transportation of the operator’s own produce or commodities, exchanges of transportation between farmers or ranchers in the immediate community, and further paragraphs in the same register. Three of its paragraphs were repealed by Laws 2009, ch. 183, § 2. Nothing in the list turns on the weight of the vehicle.
The statute does not freeze it. W.S. 31-18-303(c) provides that “unless exception is made by the department after public hearings held pursuant to the Wyoming Administrative Procedure Act, the rules of the department shall be current with rules adopted by the United States department of transportation, as now or hereafter amended.” The default is currency; a divergence requires a public hearing, which means any Wyoming-specific departure has a rulemaking record behind it rather than arriving silently.
No. No Wyoming statute read for this page names this trade, defines it, or gives it a class of authority or a schedule of its own. The state reaches the work through a compensation trigger in the carrier definitions and through equipment prongs — weight, axle count, registered weight, passenger count, placarding — written for motor carriage generally. That is the ordinary pattern; what makes Wyoming worth reading closely is that its for-compensation definition has no weight in it while its neighbor does.
Not a table, and any figure offered without seeing the operation would be invented. What an underwriter reads is the authority status, the power unit’s axle count and registered gross weight rather than its scale weight, the radius expressed as a distribution together with the recovery distances on the routes actually run, the commodity mix and the value of the heaviest load carried, whether the deposited security is written by an admitted insurer, and the additional-insured and waiver terms flowing down from shipper agreements.
Every figure on this page was read at the source below on September 1, 2026, with the effective date of the version read. Treat each as current as of that date rather than as permanent.
Send the power unit and trailer ratings separately, the radius distribution, and whether any dispatch crosses a state line. We will size the program against the work the trucks actually do rather than against a statutory floor.
