If you operate in interstate commerce, the Unified Carrier Registration (UCR) is a requirement you cannot ignore. The program ensures that carriers, brokers, freight forwarders, and leasing companies contribute fairly to funding safety enforcement across participating states.
UCR Participation by State
Currently, 41 states participate in the UCR program. The 9 non-participating states are:
- Oregon
- Wyoming
- Nevada
- Arizona
- Florida
- Vermont
- New Jersey
- Maryland
- Hawaii
If your company is based in one of these nine non-participating states but your vehicles cross into participating states, you are still required to register and pay UCR fees. Filing is done through a participating state.
The UCR program officially replaced the old Single State Registration System (SSRS) on December 31, 2006.
Why UCR Compliance Matters
- Mandatory for most carriers: Nearly all commercial carriers operating across state lines must register.
- Covers all vehicle types: Buses, coaches, tractors, and trucks tied to your USDOT number are counted under UCR.
- Immediate enforcement: When your truck goes through a weigh station, law enforcement can instantly see if your fleet is UCR-registered.
- Avoid penalties: Operating without UCR registration can result in fines and out-of-service orders.
Who Must Register Under UCR
The following are required to register annually and pay based on fleet size:
- Private property carriers
- For-hire passenger and property carriers
- Carriers of exempt commodities
- Brokers
- Freight forwarders
- Leasing companies
- Farmers regularly crossing state lines with CMVs
Both individual owner-operators and companies with large fleets fall under UCR requirements. If you lease vehicles, the carrier with operational control is responsible for paying the UCR fee.
What UCR Registration Provides
Once you’ve paid your annual UCR fee, your commercial vehicles are authorized to operate across all 50 states — even those not participating in the program.
