What is the Unified Carrier Registration (UCR)?
The Unified Carrier Registration is a federal program that requires businesses operating commercial motor vehicles in interstate or international commerce — together with brokers, freight forwarders, and leasing companies — to register every year and pay a fee scaled to fleet size. It was created by the UCR Act of 2005 and is set out in federal law at 49 U.S.C. §14504a.
It runs as a base-state system: you register and pay through a single participating state, which collects the fee on behalf of all participating states. The money supports state motor-carrier safety programs and the administration of the agreement.
Why UCR exists
- Replaced the older Single State Registration System (SSRS) with one unified, fleet-based fee.
- Lets states recover the cost of overseeing interstate carriers operating on their roads.
- Stops states from charging interstate carriers their own separate interstate-registration fees.
- Funds motor-carrier safety enforcement across participating states.
Key facts at a glance
- Annual — filed once per calendar year.
- Fleet-based fee — scales with your commercial-vehicle count.
- Interstate only — purely intrastate operations are not subject to UCR.
- No credential — nothing to display or carry in the vehicle.
- Base-state — pay through one state for all participating states.
- 2026 window — opened Oct 1, 2025; due before Jan 1, 2026.
- Covers carriers, private carriers, brokers, forwarders & leasing companies.
- Prior-year count — your fee bracket uses last year’s vehicle total.
Miss the deadline?
After January 1 the fee is still owed, and a non-registrant may face state enforcement — including fines and, in some states, being placed out of service at roadside. Penalties vary by state.
Who needs UCR — the five groups
If you are engaged in interstate or international commerce, you generally fall into one of these categories:
Motor Carriers (for-hire)
Haul property or passengers across state lines for payment.
Motor Private Carriers
Move your own goods or equipment in interstate commerce.
Freight Forwarders
Assemble & arrange interstate shipments under your own name.
Brokers
Arrange interstate transportation between shippers & carriers.
Leasing Companies
Lease commercial vehicles into interstate operations.
Brokers, leasing companies, and forwarders that do not run their own trucks pay the lowest fee bracket. Carriers (and forwarders that operate vehicles) pay according to the number of commercial motor vehicles they run.
Common exemptions
Some operations are not required to register: businesses transporting only their own people without a transportation fee (a private carrier of passengers — churches, schools, employee shuttles); operations running solely federal-government vehicles; solely emergency vehicles; and operations solely within Hawaii. And of course, purely intrastate operations fall outside UCR entirely.
Interstate vs. intrastate: the test that decides everything
UCR turns on one question: are you in interstate commerce? The distinction is about the journey of the freight or passengers, not just where your truck drives.
| Interstate — UCR applies | Intrastate — UCR does not apply |
|---|---|
| Crossing a state line or U.S. border with property or passengers. | Every trip starts and ends inside one state. |
| Carrying freight that crosses a border at any point — including hauling goods to a port or airport for export. | No load is part of a continuous interstate movement. |
| A purely in-state leg of a shipment that began in another state. | Goods originate, move, and are delivered within the same state. |
The trap most carriers miss
If your truck never leaves the state but the cargo is part of a shipment that started or will end in another state, that movement is interstate — and UCR applies. When in doubt, run the checker above or call (307) 200-8338.
Vehicles & weight: what counts, and how your fee is set
Your UCR fee bracket is driven by the number of commercial motor vehicles (power units) you operated in interstate commerce during the prior year. For UCR, a commercial motor vehicle is a self-propelled vehicle used on the highways principally to move passengers or cargo that meets any one of these tests:
- Has a GVWR or gross weight of 10,001 lbs or more — or, with a trailer, a combined rating of 10,001 lbs or more.
- Carries placarded amounts of hazardous materials, regardless of weight.
- Is designed to carry more than 10 passengers, including the driver.
This mirrors the commercial-motor-vehicle definition in 49 U.S.C. §31101. Here is how the most common situations count:
| Vehicle / factor | UCR status | How it works |
|---|---|---|
| Single truck / truck-tractor | Counts | Gross vehicle weight rating (GVWR) or actual gross weight of 10,001 lbs or more. |
| Power unit + trailer (combination) | Counts | Gross combination weight rating (GCWR) or actual combined weight of 10,001 lbs or more — even when the power unit alone is lighter. |
| Light vehicle, no trailer | Does not count | GVWR / gross weight of 10,000 lbs or less and pulling no trailer. (You still register if you hold an MC number — at the lowest bracket.) |
| Passenger vehicle | Counts | Designed to carry more than 10 passengers, including the driver. |
| Placarded hazmat vehicle | Counts | Any vehicle carrying placardable quantities of hazardous materials — regardless of weight. |
| Interstate use only | Count basis | Only count vehicles operated in interstate commerce during the prior year. (Intrastate-only school buses may be excluded from the fleet count.) |
| Prior-year snapshot | Count basis | Your fee bracket is set by the vehicle total from the preceding year; mid-year fleet changes are not refiled until the next registration. |
Light-vehicle operators, take note
If every vehicle you run is 10,000 lbs or less with no trailer, those units don’t count as commercial motor vehicles — but if you hold a federal MC number you still register, simply at the lowest bracket. Add a trailer that pushes the combination to 10,001 lbs and that unit must be counted.
2026 UCR fee brackets
Your UCR fee is a government fee set by fleet size — the more commercial vehicles you operated in interstate commerce last year, the higher your bracket. Here are the six brackets. (DotMotusCompliance’s service fee is separate and shown at checkout.)
Brokers, leasing companies, and non-vehicle freight forwarders pay the Bracket B1 fee regardless of size. Your fee does not change based on how many states you serve or which base state you use.
State-by-state: participating vs. non-participating
UCR fees are uniform nationwide — what varies by state is whether the state participates in collecting UCR. You register through your base state (your principal-place-of-business state if it participates).
✅ 41 participating states
If your business is based in one of these states, it is your base state:
❌ Non-participating states (9 states + D.C.)
These do not collect UCR. If you’re based here, you choose a base state from your region:
Choosing a base state if yours doesn’t participate
Eastern region
CT, DE, MA, ME, NH, NY, PA, RI, VA, or WV
Southern region
AL, AR, GA, KY, LA, MS, NC, OK, SC, TN, or TX
Western region
AK, CA, CO, ID, MT, ND, NM, SD, UT, or WA
Great Lakes region
IA, IL, IN, KS, MI, MN, MO, NE, OH, or WI

How to file your UCR
- Confirm your USDOT/MC record is current — name, address, and operating status should be accurate.
- Verify your interstate status using the checker above if you’re unsure.
- Count your commercial vehicles from the prior year to find your fee bracket.
- Select your base state (your home state if it participates, otherwise your regional option).
- Submit the registration and pay the fee.
- Keep your confirmation/receipt — there’s no sticker or card for the truck.
