Motor carrier classes by state
New York taxes the mile. On top of registration, on top of fuel tax, a truck over 18,000 pounds owes a tax computed on the New York public-highway miles it runs — and the exemption written for construction equipment excludes dump trucks by name.
The Highway Use Tax is the single fact that most changes how an aggregate operation is run and priced in New York, and it is the one most often missing from an out-of-state operator’s cost model. It is not a fuel tax and not a registration fee. It is a weight-distance tax: miles traveled on New York public highways, multiplied by a rate keyed to the weight of the vehicle and to a reporting method the carrier elects once a year for its entire fleet.
For a hauler moving stone, that structure has consequences a long-haul carrier never feels. Short, repetitive, heavily laden runs generate taxable miles at the loaded rate all day long. The election between the two reporting methods is made on the first return of the calendar year and cannot be changed until the next one, so a fleet that guesses wrong in January lives with the guess through December. And the exclusion that lets a grader or a scraper off the hook entirely is drafted so that a dump truck cannot reach it, no matter what job it is working.
The second New York fact is that a divisible load — which is what sand, gravel and stone are — can lawfully exceed the ordinary weight limits here, under a permit program built around a wheelbase formula. That program is capped, rationed by monthly lottery, and carries a set of downstate rights that behave like transferable property. Every figure below is tied to the publication, regulation or statute that sets it, with the issue date, revision date or edition that source displays.
Running dump work in New York? Send the HUT certificates of registration, the divisible load permit types and any downstate grandfather certificates — those three documents describe a New York aggregate operation better than the equipment list does.
The threshold is stated plainly in the Department of Taxation and Finance’s Tax Bulletin HU-115, issued April 13, 2016 and last updated March 26, 2026: “A HUT certificate of registration and decal is required for any truck, tractor, or other self-propelled vehicle with a gross weight (either alone or in combination) of more than 18,000 pounds.” A vehicular unit at 18,000 pounds or less is exempt — unless the carrier elects the unloaded weight method, in which case the thresholds drop to any truck over 8,000 pounds unloaded and any tractor over 4,000 pounds unloaded.
The tax itself is described in Tax Bulletin HU-360, issued August 1, 2014 and updated March 26, 2026: it “is computed by multiplying the number of miles traveled on New York State public highways (excluding toll-paid portions of the New York State Thruway) by a tax rate,” with the rate based on the weight of the vehicle and the method chosen. The Thruway carve-out is worth understanding for what it is — a credit for tolls already paid, not a general exemption for limited-access mileage. Miles on every other New York public highway are taxable miles.
Credentials are cheap and the paperwork is not. Bulletin HU-115 puts the HUT certificate of registration and decal fee at $1.50 per vehicle, with the same $1.50 on renewal and on a duplicate. A lease of more than 30 consecutive days generally requires the lessee to obtain its own certificate unless the vehicle will operate in New York for 10 days or less. And a weight change cuts one way: an increase must be reported and a revised certificate issued, while a decrease can be applied for at no charge only during the month of January.
We publish no rate figures here. The schedules are set by the Tax Law and appear in the department’s return instructions, and the bulletins carry a standing caveat that belongs with any figure taken from them: a Tax Bulletin “is accurate as of the date issued,” but “subsequent changes in the Tax Law or its interpretation may affect the accuracy of a Tax Bulletin,” and it does not “replace the law or change its meaning.”
Bulletin HU-360 sets out the choice and its consequences in four lines. When completing the first return for the calendar year, the carrier must choose either the gross weight method or the unloaded weight method. After selecting, the carrier “must use the same method to compute your tax for each return filed during the year,” “cannot change the selected method until the following year,” and must “use it for all your vehicles.” There is no per-unit optimization and no mid-year correction.
The gross weight method applies to every truck and tractor over 18,000 pounds gross operating on New York public highways during the reporting period. Gross weight, for this purpose, is the unloaded weight of the power unit plus the unloaded weight of the heaviest trailer, dolly or other device it will draw, plus the maximum load to be carried or drawn. The driver and a helper are excluded. That definition is built on the heaviest configuration a unit will run, not the average one, which is why a mixed fleet with a few heavy units can be pulled upward by them.
Within the gross weight method there are two sub-options. Under the straight line option the carrier computes tax vehicle by vehicle, using each laden truck’s gross weight against its laden miles and each unladen truck’s unloaded weight against its unladen miles. Under the heaviest weight option — open only to a carrier running more than one unit — the computation uses the heaviest laden units against laden miles and the heaviest unladen units against unladen miles. One demands per-unit mileage discipline; the other trades accuracy for simpler records.
The unloaded weight method reaches further down the fleet: it must be used for every truck over 8,000 pounds unloaded and every tractor over 4,000 pounds unloaded. Unloaded weight is the actual weight of the vehicle including all equipment necessary for its performance and safety, all permanently attached equipment, all equipment used exclusively to protect the load or to load and unload the vehicle, and the weight of full fuel tanks. For a dump truck, the body, the hoist, the tarp system and the tailgate are all in that number.
One narrow relief exists and aggregate is not in it. Bulletin HU-360 provides reduced tax rates for carriers with three or fewer trucks or tractors in New York used almost exclusively to transport boltwood, logs, pulpwood, woodchips, or raw unprocessed milk in bulk. Stone, sand and gravel appear nowhere on that list.
New York excludes a category of construction machinery from the Highway Use Tax altogether, on the theory that such machines are useful in building highways rather than in transporting property over them. Tax Bulletin HU-245, issued August 1, 2014 and updated March 26, 2026, describes a road-building machine as “any of the several machines that are useful in constructing highways but do not transport property over public highways,” gives motor graders and scrapers as common examples, and notes that they keep the exclusion even on a project that is not a highway.
The category is then extended to a specific kind of earthmover: a vehicle in excess of eight feet in width, equipped with pneumatic tires, and “designed, constructed, and used for transporting earth and rock in connection with excavation and grading work.” Reading only that far, an aggregate operator would reasonably think his equipment qualifies. The next sentence closes the door by name. The bulletin states: “Dump trucks, tank trucks, concrete mixers, concrete pumps, any vehicles utilizing a conventional truck chassis, and any vehicles capable of travel at a speed in excess of 40 miles per hour are not road-building machines.” Three separate disqualifiers each catch a highway dump truck on their own — it is named outright, it sits on a conventional truck chassis, and it can exceed 40 miles per hour. A grader working the same job is out of the tax; the truck feeding it is not.
Two related exclusions in the same bulletin are worth knowing because they cover equipment an aggregate contractor often owns. A power shovel — “a machine that utilizes a bucket to dig out ground, earth, stone, or similar substances, and deposit it elsewhere” — expressly includes a backhoe, front-end loader or wheeled excavator. The governing condition across the whole list is that an excluded vehicle keeps its exclusion only while used for the purpose for which it was designed, and, buses aside, “excluded vehicles may not be used to deliver passengers or materials.” Put a load of gravel in an excluded machine and the exclusion is gone. The bulletin cites Tax Law sections 501(2)(c) and 504 as its authority, and carries the same accuracy caveat as every bulletin in the series.
We place New York aggregate and dump accounts, including operators running statewide divisible load permits and fleets holding downstate grandfather rights.
The enforcement mechanism New York attaches to the Highway Use Tax is not primarily a fine — it is the registration itself, and it reaches the buyer of a used truck as well as the delinquent owner. Bulletin HU-115 states that the Department of Motor Vehicles “will not renew the registration or transfer the registered ownership of any motor vehicle that was subject to the HUT unless the Tax Department provides a Certificate of Tax Clearance,” and that the Tax Department will not issue that certificate until the taxpayer has paid all outstanding highway use tax liability.
The document is Form MT-370.1 or MT-370.2, and the bulletin adds a caution aimed directly at fleet acquisitions: “When purchasing a used vehicle that was previously registered for the HUT, be sure to obtain Form MT-370.1 before completing the purchase. If the seller owes any monies or has delinquent HUT returns, you will not be able to register the vehicle with DMV.” A buyer who closes without it has bought a truck he cannot plate.
The Tax Department can also deny a certificate of registration outright, or suspend or revoke an existing one, for any violation of the Highway Use Tax Law. So HUT compliance is not a bookkeeping detail sitting off to one side of the operation — it is a condition of the fleet continuing to be registered, and it belongs in the same conversation as the physical damage schedule when an operator is buying units out of another company.
Most states reserve overweight permits for loads that cannot be broken down. New York runs a separate program for loads that can. Its permit office states the category without ambiguity: a divisible load is cargo of legal dimensions that can be separated into units of legal weight without affecting the physical integrity of the load, and the department’s own permit FAQs give the first example as “aggregate (sand, top soil, gravel, stone),” followed by logs, scrap metal, fuel, milk and refuse.
The controlling statute is section 385 of the Vehicle and Traffic Law, which NYSDOT publishes itself: its Divisible Load Overweight Permits page links the text under the label “Title 3, Article 10, Section 385 — Dimensions and Weights of Vehicles.” One caveat travels with that convenience. The agency reprint carries no compilation date and no amendment history, so while the figures in it can be read directly, its currency cannot be confirmed from the document itself. Read against it, New York’s ordinary limits are a single-axle maximum of 22,400 pounds, 36,000 pounds on two consecutive axles spaced under eight feet, and a gross weight of 34,000 pounds plus 1,000 pounds per foot of wheelbase, capped at 80,000.
The permit weights come from a different formula. Perm 69 (SW), the department’s statewide permit-type and fee schedule dated 01/2020, states it as “(1,250 x Wheelbase) + 42,500,” with the overall wheelbase measured in inches and rounded to the nearest whole foot. A Type 1 permit — three or four axles, minimum 16-foot wheelbase, maximum trailer length 48 feet — carries a $360.00 fee and a maximum gross of 97,400 pounds. A Type 1A, requiring five or more axles, runs $750.00 for five or six axles and $900.00 for seven or more, to a maximum gross of 102,000 pounds. A Type 7 permit, at six or more axles and a minimum 36½-foot wheelbase, reaches 107,000 pounds.
Two limits matter more to a dump operator than the headline weights. Statewide permits are valid on roadways under NYSDOT jurisdiction and on the Thruway, but Perm 69 states they “are not valid for operation over local roads or on roads and bridges operated by the Metropolitan Bridge Authority (MTA), Bridge Authority and the New York City Department of Transportation” — a real constraint when the last mile is a town road. And every divisible load permit is an “R” restricted permit: permitted vehicles may not cross bridges signed “No Trucks with ‘R’ Permits” unless the bridge is officially rated as waivered. The 22,400-pound figure reappears here in a second-order role, as the steering-axle ceiling running across the Type 1, Type 1A and Type 7 permit types alike.
Before any of those weights are available, the equipment has to qualify. NYSDOT’s Divisible Load Overweight Permits page states that all vehicles — trucks, tractors and trailers — must comply with the Infrastructure Friendly Vehicle requirements to be permitted, and the requirements are specification items rather than paperwork ones. They land hardest on exactly the equipment a dump fleet runs, because they are written around lift axles.
The first requirement is a retrofit: all vehicles with a lift axle must have that axle made steerable or trackable, meaning the tires on each side will turn or pivot as the truck turns when the axle is down and in contact with the ground. The second is a placement rule with obvious intent — the air pressure control valve for the lift axle must be located outside the cab, beyond the reach of the occupants while the vehicle is in motion. That is the pressure regulator specifically, not the up-and-down lift controls.
The third is a tire rule: every axle other than a steerable or trackable one must carry two tires on each side, four to the axle, with super singles permitted only on the steering axle and on steerable or trackable lift axles. The fourth is the 80% Rule, which governs how a group must be loaded — the weight on any grouping of two or more axles must be distributed so that no axle in the grouping carries less than eighty percent of any other axle in it.
Underneath all four sits a rating rule that quietly caps the configuration. In determining permitted weights the department uses the lowest gross axle weight rating within a grouping to limit the weight allowed on every other axle in it, across tandem, tridem and quad groups — and an axle’s rating is the lesser of the manufacturer’s gross axle weight rating and the sum of the manufacturer’s tire ratings on that axle. One under-specified axle, or one set of lighter-rated tires, pulls the whole group down, which makes tire specification a permitting question rather than a maintenance one.
A qualifying truck and a completed application are still not enough, because New York caps the number of divisible load permits in existence. The governing regulation is 17 NYCRR Subpart 154-2, filed December 31, 1985 as an emergency measure and made permanent by order filed January 15, 1986 effective February 5, 1986, with its operative sections repealed and refiled February 8, 1994 effective February 23, 1994. The copy NYSDOT publishes carries a Jan-Feb 1996 footer, so it should be read as the department’s posted edition rather than as a current codification.
Section 154-2.3(f) states that the total number of overweight divisible load permits issued by the department is prescribed by section 385(15)(f) of the Vehicle and Traffic Law, and that additional permits authorized effective January 1, 1994 “are to be issued on a lottery basis.” The definition is equally direct: a lottery is “a random drawing held of all new vehicle permit applications for F1 and F2 category permits,” held monthly when permits become available.
The conditions are specific. A vehicle to be permitted must be registered in New York and maintain that registration for the period of the permit. The applicant submits a completed lottery application on form PERM 92, the fee, a copy of the current registration, and the manufacturer’s ratings data — a legible photograph of the door data plate is accepted in its place. And then the provision that belongs on an insurance page: “if selected, the applicant will be required to supply a certificate of insurance (PERM 17) before permit is issued.”
Below the lottery sits an older layer. Under section 154-2.16(b), the replacement rights for F3, F4, F5 and F6 category permits — the downstate categories, covering state highways in the counties of Westchester, Rockland, Nassau, Suffolk, Putnam, Orange and Dutchess — “attach to a self-powered vehicle, tractor or power unit which was registered in New York at some time prior to January 1, 1986 and which was operational on public highways at some time during the three-year period prior to January 1, 1986.” Eligibility, in other words, is anchored to a status a truck’s predecessor held four decades ago.
The rights are evidenced by a certificate of grandfather rights, and the regulation is explicit that a purchaser without one gets nothing: “the new owner of a business will not be eligible for a divisible load overweight permit for the purchased vehicle(s) if there is not a certificate of grandfather rights submitted with the permit application.” Permit rights “cannot be transferred to a new owner or company unless they are being transferred with the vehicle and are part of the sale of the business.” That makes them a real, saleable, but tightly conditioned asset.
The conditions are set out in NYSDOT Divisible Load Notice DLN 10-02, dated 6/21/2010, which supersedes DLN 09-09 and cites Vehicle and Traffic Law § 385(15)(f) and 17 NYCRR § 154-2.16(b) as its authority. To sell a single power unit with grandfather rights, the unit must have been actively permitted for the past five consecutive years at the time of sale, and the purchaser must already hold current downstate rights or active downstate permits on other vehicles. Banked rights cannot be sold with a single vehicle at all — “they can only be sold as part of a sale of the current owners’ entire business.” A certificate marked “Non-Transferrable” cannot be sold to anyone, cannot be banked, and may only be kept active by the current owner. And if the seller’s account carries a status of VOID in the Central Permit Office system, “any and all downstate rights and/or permits, will also be considered null and void.”
Banked weight is the companion concept, governed by section 154-2.18 and confined to the F4, F5 and F6 categories. A registered owner’s banked capacity had to have been established with the department prior to January 1, 1988, and it can only justify acquiring additional vehicles as replacements — never a replacement with greater gross weight capacity than the vehicle replaced.
None of this is insurance, but all of it is diligence. When a New York dump operation changes hands the permits and certificates behind them are frequently worth more than the iron, and they are extinguishable by an administrative status a buyer cannot see from the outside.
The state minimum is a licensing threshold. The program an operator actually needs is built from these lines:
We write dump and aggregate hauling as a named class rather than as an exception to general trucking, and we read each account against the weight and permit regime of the state it operates in. For a New York operator that means starting from what the trucks are actually licensed and configured to carry, sizing physical damage to bodies and hoists rather than to a chassis value, and treating pit, stockpile and job-site work as its own exposure rather than an extension of the highway auto form.
If the operation also runs freight under separate authority, the New York trucking insurance page covers the state’s broader motor carrier picture, and the dump trucking insurance page covers the class mechanics that apply wherever the operator runs.
Yes, above the threshold. Tax Bulletin HU-115, issued April 13, 2016 and updated March 26, 2026, requires a HUT certificate of registration and decal for any truck, tractor or other self-propelled vehicle with a gross weight, alone or in combination, of more than 18,000 pounds. A unit at 18,000 pounds or less is exempt unless the carrier elects the unloaded weight method, which reaches every truck over 8,000 pounds unloaded and every tractor over 4,000 pounds unloaded.
No. Tax Bulletin HU-245, issued August 1, 2014 and updated March 26, 2026, states that “dump trucks, tank trucks, concrete mixers, concrete pumps, any vehicles utilizing a conventional truck chassis, and any vehicles capable of travel at a speed in excess of 40 miles per hour are not road-building machines.” Each of those three clauses independently disqualifies a highway dump truck. A motor grader or scraper on the same project keeps the exclusion; the truck hauling to it does not.
Tax Bulletin HU-360, issued August 1, 2014 and updated March 26, 2026, states that the tax is computed by multiplying miles traveled on New York State public highways — excluding toll-paid portions of the New York State Thruway — by a rate based on the weight of the vehicle and the reporting method chosen. We do not publish rate figures here; take them from the current Form MT-903 instructions, since the department’s bulletins carry their own caveat that they are accurate only as of the date issued.
Yes, which is unusual. New York runs a divisible load overweight permit program, and NYSDOT’s permit FAQs give “aggregate (sand, top soil, gravel, stone)” as the leading example of a divisible load. Permitted gross weight is set by the F1 formula in Perm 69 (SW), dated 01/2020: (1,250 × wheelbase in feet) + 42,500, with a Type 1 permit at $360.00 reaching 97,400 pounds and a Type 1A at $750.00 or $900.00 reaching 102,000 pounds.
Because the number of divisible load permits is capped by statute. 17 NYCRR § 154-2.3(f) states that the total number issued is prescribed by Vehicle and Traffic Law § 385(15)(f), and that additional permits authorized effective January 1, 1994 are to be issued on a lottery basis. Section 154-2.2 defines the lottery as a random drawing of all new vehicle permit applications for F1 and F2 category permits, held monthly when permits become available. A selected applicant must supply a certificate of insurance on form PERM 17 before the permit issues.
They are permit eligibility rights for the F3 through F6 categories covering state highways in Westchester, Rockland, Nassau, Suffolk, Putnam, Orange and Dutchess counties. Under 17 NYCRR § 154-2.16(b) they attach to a power unit registered in New York before January 1, 1986 and operational during the three years before that date. They can be sold, but only with the vehicle and as part of the sale of the business, and DLN 10-02 dated 6/21/2010 requires that the unit have been actively permitted for the past five consecutive years at the time of sale.
They are the equipment conditions NYSDOT requires of every vehicle permitted under a divisible load overweight permit. Lift axles must be retrofitted to be steerable or trackable; the lift-axle air pressure control valve must sit outside the cab beyond the occupants’ reach while the vehicle is in motion; every non-steerable axle needs four tires; and under the 80% Rule no axle in a grouping may carry less than eighty percent of any other in that grouping. Permitted weight is limited by the lowest gross axle weight rating in each group.
Every figure on this page was read at the source below on August 11, 2026, with the effective date of the version read. Treat each as current as of that date rather than as permanent.
Send the declared or registered weights alongside the axle configurations, and tell us where the material moves from. We will size the program against the work the trucks actually do rather than against a statutory floor.
