Who pays
| Category | Who this is | Fee basis |
|---|---|---|
| Motor carrier (for-hire) | Moves other people's freight or passengers for compensation. | By fleet size |
| Motor private carrier | Moves its own goods in support of its primary business — contractors, retailers, farms, manufacturers. | By fleet size |
| Exempt carrier | Hauls commodities exempt from economic regulation (some agricultural products) and needs no MC authority. Not exempt from UCR. | By fleet size |
| Freight forwarder | Consolidates shipments and takes responsibility for the transportation. | By fleet size (lowest bracket if no vehicles) |
| Broker | Arranges transportation; operates no vehicles. | Lowest bracket ($55 in 2027) |
| Leasing company | Leases vehicles without drivers to carriers. | Lowest bracket ($55 in 2027) |
| Carrier + broker (or forwarder, or lessor) | Holds more than one role. | One fee, as a carrier, on the whole fleet |
Canadian and Mexican companies that operate in the United States are covered too. Source: 49 U.S.C. 14504a; the carrier-plus-broker rule is confirmed on the New Mexico, Connecticut and Indiana state pages.
What counts as a commercial motor vehicle
A self-propelled vehicle used on public roads in commerce to move freight or passengers that meets any one of these:
- gross vehicle weight rating or actual weight of 10,001 lbs or more; or
- combined with its trailer, a rating or actual weight of 10,001 lbs or more; or
- carries placarded hazardous materials, at any weight; or
- is designed to carry more than 10 passengers including the driver (11+ seats).
Wording varies: Wisconsin and Washington pages say “10 or more” passengers. The federal definition in 49 U.S.C. 31101 and the UCR FAQ say “more than 10”.

What “interstate” means
It is wider than “I cross state lines.” The UCR Plan's own questionnaire asks two questions:
- Do you transport freight or passengers across state or national boundaries?
- Does the freight or do the passengers cross a boundary at any point in the journey — including before you pick them up or after you deliver?
Example: you move containers from the Port of Los Angeles to a warehouse in California and never leave the state. The container arrived from China, so your leg is part of an international movement and UCR almost certainly applies. The same logic covers rail intermodal transfers and interline freight.
Not sure? Take the six-question check — it mirrors the official questionnaire.
Who is exempt
| Who | Why |
|---|---|
| Operations entirely within one state, moving freight that neither came from nor goes to another state | Not interstate commerce |
| Private carriers of passengers — church buses, school and company shuttles carrying their own people, not the public | Explicit statutory exclusion |
| Operations only in Hawaii; transportation solely for the federal government; certain emergency vehicles | Listed in the official questionnaire; confirm details there |
Some states extend UCR to intrastate carriers under §14504a(j). Washington's UTC, for example, says intrastate passenger carriers must register. Check your own state.
Myths that get people fined
- “All my vehicles are under 10,000 lbs.” You still register; your count is 0 and you pay the lowest bracket. But a light pickup pulling a trailer that together weigh 10,001 lbs counts.
- “I only haul my own goods.” That is a private carrier. Private carriers register.
- “My MC authority is revoked.” The UCR FAQ says you still fall under the Agreement if you operate in interstate commerce.
- “My state doesn't participate.” Not an exemption. You choose a base state from the regional list and pay the same fee.
- “My vans seat 10 or fewer.” You still register; it only affects the count.
- “I'm a broker, I don't own trucks.” Brokers register every year at the lowest bracket. Details here.
