Why UCR Is Required for Interstate Commerce
The UCR program was created to:
-
Replace older state-by-state carrier registration systems
-
Allow states to collect fees from interstate carriers
-
Fund motor carrier safety enforcement and compliance programs
If you operate in interstate commerce, UCR registration is mandatory unless you qualify for a specific exemption.
Who Must Register for UCR in Interstate Commerce?
You must register for UCR if you operate interstate as any of the following:
-
For-hire motor carriers
-
Private motor carriers
-
Brokers
-
Freight forwarders
-
Leasing companies
This applies whether you are:
-
A single-truck owner-operator
-
A fleet carrier
-
Based in any U.S. state or U.S. territory
What Vehicles Are Covered?
UCR applies to commercial motor vehicles that:
-
Have a GVWR or GCWR of 10,001 lbs or more, or
-
Are used to transport hazardous materials requiring placards
UCR Applies Even If:
-
You operate in only one state but your freight crosses state lines
-
You already have a USDOT number
-
You are registered for IRP or IFTA
-
You rarely run interstate loads (even one trip triggers UCR)
Who Is Exempt from UCR?
UCR generally does not apply to:
-
Intrastate-only carriers (no interstate connection)
-
Vehicles under 10,001 lbs not hauling placarded hazmat
-
Certain government and non-profit vehicles
UCR Is an Annual Requirement
-
UCR must be renewed every year
-
Fees are based on the number of commercial vehicles
-
Failure to register can result in fines, roadside enforcement, or vehicle out-of-service orders
Enforcement of UCR in Interstate Commerce

-
Roadside inspections
-
Weigh stations
