1. What Is the UCR Program?
The UCR program is administered jointly by all 50 states and the District of Columbia. It replaced the former Single State Registration System (SSRS) to streamline and standardize registration for carriers operating across state lines.
Even though UCR is a federal program, each state (including Wisconsin) handles the processing and enforcement of registrations within its borders.
2. Who Must Register for UCR in Wisconsin?
If your business meets the following criteria, you must file a UCR registration:
-
You operate commercial motor vehicles in interstate commerce
-
You are a:
-
Motor carrier
-
Motor private carrier
-
Freight forwarder
-
Broker
-
Leasing company
-
-
Your vehicles have a gross vehicle weight rating (GVWR) ≥ 10,000 lbs, or you transport 9–15 passengers (including driver) for compensation, or 16+ passengers with no compensation
Note: Intrastate carriers (operating only within Wisconsin) might be exempt, but certain Wisconsin intrastate carriers still must register if they meet federal criteria.
3. When to File UCR
UCR registration is annual. The registration year runs from January 1 to December 31.
The deadline to register and pay fees is December 31 preceding the registration year. For example, for 2026 registration, you must file and pay by December 31, 2025.
4. How Fees Are Calculated
UCR fees are based on your fleet size — the number of commercial vehicles your company operates. The more vehicles you have, the higher the fee bracket you fall into.
Missed fees or underreported fleet size can result in back fees, fines, and penalties.
5. Penalties for Non-Compliance
Failing to register or pay UCR fees can lead to:
-
Civil penalties
-
FMCSA enforcement actions
-
Vehicle impoundment or operating authority suspension
-
Increased fees and back payments
Wisconsin authorities may also enforce penalties beyond federal actions.
