Trucking Permit Glossary

Plain-English definitions of every state trucking-permit, weight-distance tax, and oversize/overweight term you run into running multi-state. Permits are state-administered — issued by each state’s DMV or transportation agency, separate from federal FMCSA authority. 45 terms.

3

30-Day Permit(Temporary 30-Day Permit · Monthly Trip Permit): A temporary operating or registration permit valid for 30 days, offered by some states as a middle ground between a 72-hour trip permit and full annual registration. It suits a carrier that needs a few weeks of operation in a state — a short-term contract or seasonal run — without committing to a year-long account. Availability, scope, and cost vary by state.; See also: 72-Hour Permit, Trip Permit, Single-Trip vs Annual Permit

7

72-Hour Permit(3-Day Permit · 72-Hour Trip Permit): The most common form of trip permit, valid for 72 hours from issuance. It authorizes a commercial vehicle to operate in a state for a single short trip without enrolling in the state's ongoing registration or weight-distance program. Carriers crossing a state only a few times a year use 72-hour permits per trip rather than opening a full account that requires periodic returns.; See also: Trip Permit, 30-Day Permit, Fuel Permit

A

Apportioned Plate(IRP Plate · Apportioned Tag): The license plate issued under the International Registration Plan to a vehicle registered in multiple jurisdictions. Fees are "apportioned" — divided among the member states and provinces by the share of total fleet miles run in each. It lets one truck operate interstate on a single plate instead of registering separately in every state. Issued and renewed through the carrier's base jurisdiction.; See also: IRP, Base Plate, Base Jurisdiction
Axle Weight(Per-Axle Weight · Axle Load): The portion of a vehicle's total weight carried by a single axle or axle group. States cap axle weights — commonly 20,000 lbs on a single axle and 34,000 lbs on a tandem — to protect pavement and bridges, independent of the 80,000-lb gross limit. A load can be under gross weight yet still need an overweight permit because one axle group is over. Adding axles spreads weight and can keep a load legal.; See also: Overweight Permit, Gross Vehicle Weight (GVW), Bridge Formula

B

Base Jurisdiction(Base State): The single state or province a carrier designates as its home for IRP registration and IFTA fuel-tax filing. The base jurisdiction collects the carrier's apportioned fees and quarterly fuel-tax returns and settles the amounts owed to every other jurisdiction the carrier operated in. A carrier qualifies a state as its base by having an established place of business and mileage there.; See also: IRP, IFTA, Base Plate
Base Plate(Base Jurisdiction Plate): The home-state registration a carrier files its IRP apportioned registration against. The base jurisdiction is where the carrier has an established place of business, accrues mileage, and keeps its operational records. All apportioned fees, renewals, and credentials route through the base plate state, which then distributes fees to the other jurisdictions where the vehicle runs.; See also: Apportioned Plate, IRP, Base Jurisdiction
Bridge Formula(Federal Bridge Formula · Bridge Gross Weight Formula): A federal calculation that limits how much weight can rest on a group of axles based on the number of axles and the distance between them, designed to protect bridges. It governs how weight must be distributed across a truck, not just the 80,000-lb total. Overweight-permit applications often require a bridge-formula or axle-spacing analysis so the state can confirm the configuration is safe for its structures.; See also: Axle Weight, Overweight Permit, Gross Vehicle Weight (GVW), Route Survey

C

CA Number(CA# · California Carrier Number · CHP CA Number): The California identification number the California Highway Patrol assigns to motor carriers operating in the state. It is one of the two California credentials a carrier typically needs; the other is the DMV Motor Carrier Permit. The CA number ties the carrier to its CHP safety record. California runs both programs at the state level, on top of any federal USDOT/MC authority.; See also: California Motor Carrier Permit, State Operating Authority
California Motor Carrier Permit(CA MCP · Motor Carrier Permit · MCP): The permit the California DMV requires of carriers operating commercial vehicles in California. It is issued alongside, but separately from, the CHP-assigned CA number, and proves the carrier has met California's registration and insurance requirements. Carriers running in California generally need both the Motor Carrier Permit and the CA number — bundled together in Fast Permit's California package.; See also: CA Number, State Operating Authority
CT HUT(Connecticut Highway Use Fee · Connecticut HUF · CT Highway Use Tax): Connecticut's Highway Use Fee, a per-mile charge on heavy multi-unit vehicles with a gross weight of 26,000 lbs or more, in effect since 2023. Eligible carriers register for a Highway Use Fee permit with the Connecticut Department of Revenue Services and file monthly returns. It is a state mileage charge layered on top of IFTA fuel tax — not a federal filing.; Read the full guide →See also: Weight-Distance Tax, NY HUT, Massachusetts Registration

E

Escort / Pilot Car(Pilot Car · Escort Vehicle · Flag Car): A vehicle that travels ahead of or behind an oversize load to warn traffic and guide the load through hazards. State permits dictate when escorts are required, based on the load's width, height, or length, and how many. Larger loads may require certified pilot-car operators or police escorts. Height-pole cars check overhead clearances. Escort requirements and certification rules vary state by state.; See also: Oversize Permit, Superload, Route Survey, Heavy Haul

F

FMCSA(Federal Motor Carrier Safety Administration): The U.S. Department of Transportation agency that regulates interstate commercial carriers, issues USDOT and MC numbers, and writes the federal safety rules. FMCSA authority governs interstate operation; it does not issue the state trip permits, weight-distance tax accounts, or intrastate authority covered in this glossary. Those are administered by individual state DMVs, revenue departments, and transportation agencies — a separate compliance layer from the federal one.; See also: MC Number, USDOT Number, State Operating Authority
Fuel Permit(Temporary Fuel Permit · IFTA Trip Permit): A temporary credential that lets a carrier operate in a state for fuel-tax purposes without holding an IFTA license, or that covers a non-IFTA vehicle for a single crossing. A carrier without an active IFTA decal needs a fuel permit (often bundled with a trip permit) to legally fuel and run through the state. State-issued and typically valid for a few days.; Read the full guide →See also: IFTA, IFTA Decal, Trip Permit

G

Gross Combination Weight (GCW)(GCW · Gross Combination Weight Rating · GCWR): The total weight of a power unit plus all towed units and the freight aboard — the combined weight of the whole rig. Several state weight-distance programs key their thresholds off combined gross weight (Kentucky's KYU starts at 60,000 lbs GCW, for instance). It is the figure scales read for enforcement, and the number that determines whether an overweight permit is needed for a given route.; See also: Gross Vehicle Weight (GVW), Axle Weight, Overweight Permit, KYU (Kentucky)
Gross Vehicle Weight (GVW)(GVW · Gross Vehicle Weight Rating · GVWR): The total weight of the vehicle plus its load, fuel, and occupants. The federal limit on the Interstate highway system is 80,000 lbs without a permit; loads above that need a state overweight permit for each state crossed. GVW also sets thresholds for many state programs — for example New York HUT (18,000+ lbs) and several weight-distance taxes key their applicability off declared gross weight.; See also: Overweight Permit, Axle Weight, Bridge Formula, Gross Combination Weight (GCW)

H

Heavy Haul(Heavy Haul Trucking · Specialized Heavy Transport): The specialized transport of loads that exceed standard legal weight or dimension limits — construction equipment, transformers, industrial machinery, wind components. Heavy-haul moves routinely require both oversize and overweight permits in every state crossed, multi-axle trailers to spread weight, escorts, and route surveys. Because each state permits the load separately, a multi-state heavy haul means assembling a stack of per-state permits before the wheels turn.; See also: Overweight Permit, Oversize Permit, Superload, Axle Weight, Gross Combination Weight (GCW)
Hunter's Permit(Hunter Permit · Unladen Permit): A temporary permit that lets an owner-operator legally move a vehicle without a load — typically after leaving one carrier and before leasing onto another, when the truck has no active apportioned registration. It covers the "bobtail" or unladen movement of the tractor (sometimes with an empty trailer) for a short window. State-issued and time-limited; it does not authorize hauling freight for hire.; See also: Unladen / Dolly Permit, Trip Permit, Temporary Operating Authority

I

IFTA(International Fuel Tax Agreement): A multi-jurisdiction agreement among the 48 contiguous U.S. states and 10 Canadian provinces that simplifies fuel-tax reporting for vehicles running across state lines. A carrier registers with its base state, displays an IFTA decal, and files one quarterly return; IFTA redistributes the tax to each jurisdiction by miles actually driven there. Required for most vehicles over 26,000 lbs or with three or more axles. State-administered, separate from FMCSA authority.; See also: IFTA Decal, Fuel Permit, IRP, Base Jurisdiction
IFTA Decal(Fuel Tax Decal · IFTA Sticker): The annual sticker an IFTA-licensed carrier must display on both sides of the cab, paired with a paper IFTA license carried in the vehicle. The decal proves enrollment in the quarterly fuel-tax program. A vehicle without a current decal needs a temporary fuel permit to run through an IFTA state legally. Decals are issued by the carrier's base jurisdiction.; See also: IFTA, Fuel Permit, Base Jurisdiction
Intrastate Authority(Intrastate Operating Authority): Permission to haul commercially within a single state, where both pickup and delivery are inside that state and no interstate freight is involved. Intrastate carriers fall under state rules rather than the FMCSA, and many states require their own operating authority, a state DOT number, and state-specific insurance filings. Crossing a state line, or carrying interstate freight, moves the carrier into federal jurisdiction instead.; See also: State Operating Authority, Temporary Operating Authority, Ohio PUCO
IRP(International Registration Plan · Apportioned Registration): A reciprocal registration agreement among U.S. states and Canadian provinces that lets a commercial vehicle display a single apportioned license plate while operating in multiple member jurisdictions, with registration fees split by the percentage of miles driven in each. IRP is the registration companion to IFTA on the fuel-tax side. Both are state-administered through the base jurisdiction and are separate from federal operating authority.; See also: Apportioned Plate, Base Plate, IFTA, Base Jurisdiction

K

KYU (Kentucky)(KYU Number · Kentucky Weight-Distance Permit · Kentucky Unified Carrier): Kentucky's weight-distance tax license, required for vehicles with a combined gross weight of 60,000 lbs or more operating on Kentucky highways. The carrier obtains a KYU number from the Kentucky Transportation Cabinet and files quarterly mileage tax returns. It is distinct from Kentucky's separate KIT/IFTA fuel credentials and from IRP registration, and is a state program — not federal FMCSA authority.; Read the full guide →See also: Weight-Distance Tax, NY HUT, Oregon Permit

M

Massachusetts Registration(MA Carrier Registration · Massachusetts DPU): Massachusetts administers its own intrastate motor-carrier registration and operating obligations through the Department of Public Utilities and the RMV, on top of federal USDOT authority. Carriers running intrastate in Massachusetts may need state registration and to satisfy state insurance and safety requirements. As with every state program here, it is issued and enforced at the state level, distinct from an FMCSA MC number.; Read the full guide →See also: CT HUT, State Operating Authority, Intrastate Authority
MC Number(Motor Carrier Number · Operating Authority): The FMCSA-issued operating-authority number that lets a for-hire carrier haul regulated freight across state lines. It is a federal credential — distinct from the state permits, registrations, and weight-distance accounts a carrier also needs to run legally in individual states. Holding an MC number does not exempt a carrier from state operating authority, trip permits, or weight-distance tax registration.; See also: USDOT Number, State Operating Authority, FMCSA

N

NM Weight-Distance Tax(New Mexico Weight-Distance Tax · NM WDT · New Mexico W&D): New Mexico's weight-distance tax, required for commercial vehicles with a declared gross weight of 26,000 lbs or more operating on New Mexico highways. The carrier registers for a WDT permit and ID number with the NM Taxation and Revenue Department and files mileage-based returns. Like the other weight-distance states, it stacks on top of IFTA fuel tax and IRP registration rather than replacing them.; Read the full guide →See also: Weight-Distance Tax, NY HUT, KYU (Kentucky)
NY HUT(New York Highway Use Tax · New York HUT Permit): New York's Highway Use Tax, required for most motor vehicles with a gross weight over 18,000 lbs (or unloaded weight thresholds for trucks/tractors) that use New York public highways. The carrier registers with the NY Department of Taxation and Finance, receives a HUT certificate and decal, and files periodic mileage-based returns. It must be in place before the first New York trip and is separate from IFTA and IRP.; Read the full guide →See also: Weight-Distance Tax, KYU (Kentucky), NM Weight-Distance Tax

O

Ohio PUCO(PUCO Authority · Ohio Intrastate Authority): Operating authority from the Public Utilities Commission of Ohio for carriers hauling intrastate within Ohio. PUCO registration covers the state-level safety and insurance requirements for in-state commercial operations. As with California and Texas, federal interstate authority does not replace Ohio's intrastate PUCO requirement for carriers running loads that begin and end inside Ohio.; See also: State Operating Authority, Intrastate Authority
Oregon Bond(ODOT Weight-Mile Bond · Oregon Highway Use Tax Bond): A surety or cash bond the Oregon Department of Transportation can require when a carrier opens a Weight-Mile Tax account, especially for new accounts without an Oregon filing history. It secures payment of the mileage tax the carrier will owe. The bond amount scales with the size of the operation; once a clean payment record is established, ODOT may reduce or release it.; See also: Oregon Permit, Weight-Distance Tax
Oregon Permit(Oregon Weight-Mile Tax · OR Weight-Mile · Oregon Highway Use Tax): Oregon levies a Weight-Mile Tax instead of taxing diesel at the pump, so Oregon is not an IFTA fuel-tax state for diesel. Carriers over 26,000 lbs set up an Oregon Department of Transportation account, may post a bond, and report miles at rates that climb with declared weight. New or occasional operators can run on an Oregon temporary pass instead of a full account until they enroll.; Read the full guide →See also: Weight-Distance Tax, Oregon Bond, Trip Permit
Out-of-Service Order(OOS Order · Out of Service): An enforcement action that legally bars a vehicle or driver from operating until a violation is corrected. Missing or invalid state permits — no trip permit, no weight-distance registration, an unpermitted overweight load — can trigger one at a weigh station or port of entry. The truck cannot move freight until the issue is resolved, which can mean buying the permit on the spot plus paying the fine.; See also: Port of Entry, Overweight Permit, Trip Permit
Oversize Permit(Wide-Load Permit · OS Permit): A state-issued permit required when a vehicle or its load exceeds the legal dimension limits — commonly 8.5 ft wide, 13.5–14 ft high, or set length limits. Each state issues its own oversize permit, sets its own fees, and may dictate travel times, routing, and warning devices. Oversize permits are dimension-based; an overweight permit is the separate weight-based credential, and many loads need both.; Read the full guide →See also: Overweight Permit, Superload, Escort / Pilot Car, Route Survey, Single-Trip vs Annual Permit
Overweight Permit(OW Permit · Heavy-Load Permit): A state-issued permit required when a vehicle's gross weight or axle weight exceeds the legal maximum — typically 80,000 lbs gross on the Interstate, with axle limits set by the federal bridge formula. Each state issues its own overweight permit and may require axle-weight breakdowns, specific routing, or bridge analysis. It is distinct from an oversize (dimension) permit, and many heavy hauls require both at once.; Read the full guide →See also: Oversize Permit, Axle Weight, Gross Vehicle Weight (GVW), Bridge Formula, Superload

P

Port of Entry(Weigh Station · Inspection Station): A state checkpoint — often at a border or weigh station — where commercial vehicles are checked for weight, credentials, and permits. Officers verify trip permits, weight-distance registration, fuel credentials, and oversize/overweight permits, and can place a truck out of service or issue fines for anything missing. Ports of entry are where state permit enforcement actually happens, which is why credentials must be in hand before the crossing.; See also: Weight-Distance Tax, Overweight Permit, Trip Permit

R

Route Survey(Route Study · Pre-Trip Route Survey): A physical or engineered check of a proposed haul route to confirm an oversize or superload can pass — verifying bridge capacity, overhead clearances, turn radii, road width, and obstructions. States often require a route survey before issuing a superload permit, and the findings shape the approved routing and escort plan. For extreme loads the survey may involve a state DOT structural review of every bridge on the route.; Read the full guide →See also: Superload, Oversize Permit, Escort / Pilot Car, Bridge Formula, Overweight Permit

S

Single-State Permit(Per-State Permit): A permit that covers operation, registration, or a weight-distance tax in exactly one state. Because U.S. trucking permits are state-administered, a carrier running through several states generally assembles one permit per state rather than a single national credential. Fast Permit's single-state filing is a $75 flat fee per state; the Big Four bundle combines four weight-distance states in one order.; Read the full guide →See also: Weight-Distance Tax, Trip Permit, Single-Trip vs Annual Permit
Single-Trip vs Annual Permit(Trip vs Annual · Per-Trip vs Annual Permit): Two ways to buy an oversize/overweight or operating permit. A single-trip permit covers one move over a defined route within a short validity window — best for occasional or one-off hauls. An annual (or blanket) permit covers repeated moves of a given configuration for a year at a flat fee — cheaper per trip for carriers that run the same oversize load regularly. Availability and limits vary by state and load type.; Read the full guide →See also: Trip Permit, Oversize Permit, 30-Day Permit
State Operating Authority(Intrastate Operating Authority · State Carrier Authority): A state's own permission to operate commercially within its borders, separate from a federal FMCSA MC number. A carrier that runs purely intrastate, or that hauls for hire inside certain states, may need state-issued authority — California's CA number, the Texas TxDMV registration, or Ohio PUCO authority, for example. Federal interstate authority does not satisfy these state-level intrastate requirements.; See also: CA Number, California Motor Carrier Permit, TxDMV Registration, Ohio PUCO, Intrastate Authority
Superload(Super Load · Superload Permit): An oversize/overweight load so large it exceeds a state's normal permit thresholds — each state sets its own cutoff, often around 16 ft wide, 16 ft high, 200,000 lbs, or extreme length. Superloads need special engineering review: route surveys, bridge analysis, utility coordination, and police or pilot-car escorts. They carry longer lead times and far higher fees than a standard oversize permit, and approval is case-by-case.; Read the full guide →See also: Oversize Permit, Overweight Permit, Route Survey, Escort / Pilot Car, Single-Trip vs Annual Permit

T

Temporary Operating Authority(Temporary Authority · TOA): Short-term permission to operate while full credentials are pending or for a one-time need. At the state level this can mean a temporary intrastate authority or a trip permit that lets a carrier run legally for a defined window before a permanent account or registration is issued. It bridges the gap so a carrier can keep moving freight rather than sitting idle waiting on paperwork.; See also: Trip Permit, Intrastate Authority, State Operating Authority
Trip Permit(Temporary Trip Permit · 72-Hour Permit · Single-Trip Permit): A short-term credential — most commonly valid 72 hours, sometimes up to 30 days — that authorizes a commercial vehicle to operate in a state without enrolling in that state's full registration, fuel-tax, or weight-distance program. Carriers that cross a state only occasionally buy a trip permit per crossing instead of opening an ongoing account. Each state issues its own through its DMV or revenue agency.; Read the full guide →See also: Fuel Permit, Single-Trip vs Annual Permit, Temporary Operating Authority, Hunter's Permit
TxDMV Registration(Texas DMV Registration · Texas Motor Carrier Registration · TxDMV Number): The intrastate motor-carrier registration the Texas Department of Motor Vehicles requires of carriers operating commercially within Texas. It establishes state operating authority and insurance on file for intrastate Texas hauling, separate from federal FMCSA authority. Carriers running purely interstate through Texas have different obligations than those picking up and delivering inside the state.; See also: State Operating Authority, Intrastate Authority

U

UCR(Unified Carrier Registration): An annual federal-state program requiring interstate motor carriers, brokers, leasing companies, and freight forwarders to register and pay a fee tiered by fleet size, remitted through a single base state. UCR is interstate-focused and separate from the per-state operating permits and weight-distance taxes this glossary covers, though carriers commonly handle both. Operating without a current UCR draws citations in participating states.; See also: IFTA, IRP, FMCSA
Unladen / Dolly Permit(Unladen Permit · Dolly Permit · Bobtail Permit): A permit authorizing the movement of an empty (unladen) commercial vehicle or a converter dolly that has no registration of its own. Like a hunter's permit, it covers repositioning equipment — moving a tractor or dolly between jobs or terminals without carrying a paying load. It is a short-term state credential and is not a substitute for the registration and authority needed to haul freight.; See also: Hunter's Permit, Trip Permit
USDOT Number(DOT Number): The identifier the FMCSA assigns to commercial vehicle operators subject to federal safety regulation; it must be displayed on the vehicle. Most state permit and registration applications ask for it because the state ties its own credentials to the federal record. The USDOT number is not a permit or operating authority by itself — it identifies the carrier, while each state permit grants the specific privilege to operate or be taxed there.; See also: State Operating Authority, MC Number, Intrastate Authority

W

Weight-Distance Tax(Weight-Mile Tax · Mileage Tax): A state tax on heavy commercial vehicles calculated from the miles driven in that state at a rate that rises with the vehicle's weight — separate from, and in addition to, IFTA fuel tax. Only a handful of states levy one. Carriers register for an account, then file periodic mileage returns. The programs are state-run; New York, Kentucky, New Mexico, and Oregon each operate their own version.; Read the full guide →See also: NY HUT, KYU (Kentucky), NM Weight-Distance Tax, Oregon Permit, CT HUT
