What Is UCR?
The Unified Carrier Registration (UCR) program is a federally mandated system that requires certain interstate motor carriers, brokers, freight forwarders, and leasing companies to register annually and pay a fee based on fleet size.
UCR is not a permit — it is an annual registration requirement tied to your USDOT number.
Who Must Register for UCR in Illinois?
You must register for UCR if your Illinois-based company:
-
Operates interstate (crosses state lines OR transports interstate freight within Illinois)
-
Has an active USDOT number
-
Operates as:
-
Motor Carrier
-
Broker
-
Freight Forwarder
-
Leasing Company
-
Even if you only have one truck, you must register if you engage in interstate commerce.
Who Is Exempt?
You generally do NOT need UCR if you:
-
Operate strictly intrastate (no interstate commerce)
-
Do not transport interstate freight
-
Are a government entity
However, many carriers mistakenly believe they are intrastate when they are legally considered interstate due to freight origin/destination crossing state lines.
Illinois UCR Fees
UCR fees are based on the number of commercial motor vehicles you operate in interstate commerce.
Fee tiers typically include:
-
0–2 vehicles
-
3–5 vehicles
-
6–20 vehicles
-
21–100 vehicles
-
101–1,000 vehicles
-
1,001+ vehicles
Fees change periodically, so carriers should verify current rates before filing.
Registration Deadline
UCR registration must be completed annually, typically by December 31 for the upcoming registration year.
Late registration can result in:
-
State enforcement penalties
-
Roadside citations
-
Additional administrative fees
