Sell My TruckOverview
49 CFR Part 367 establishes the standards for the Unified Carrier Registration (UCR) program, the annual registration system that replaced the old Single State Registration System (SSRS) for interstate motor carriers, motor private carriers, freight forwarders, leasing companies, and brokers engaged in interstate commerce.
Under UCR, carriers register once per year through a participating state and pay a fee based on the size of their fleet. Fees are distributed among the participating states. The registration year runs from January 1 through December 31, and registration for the upcoming year typically opens in October. Operating without a current UCR registration while engaged in interstate commerce is a violation enforceable at roadside.
UCR fee tiers are set by fleet size — from 0-2 vehicles at the lowest tier to 1,000+ vehicles at the highest. Brokers and freight forwarders pay a flat fee. The UCR fee is separate from and in addition to other federal and state fees, including FMCSA operating authority fees, state registration fees, and IFTA fuel tax obligations.
Key Provisions
- Requires annual registration and fee payment for interstate carriers, brokers, and freight forwarders.
- Fees scale based on number of commercial motor vehicles operated — 9 tiers from 0-2 to 1,000+ vehicles.
- Registration is annual (January 1–December 31) with enrollment typically opening each October.
- Replaces the old Single State Registration System (SSRS) with a single unified national program.
- Non-compliance can result in roadside violations and loss of operating privileges.
Why It Matters to Truck Owners
UCR is an annual compliance obligation that every interstate carrier must track. Missing the registration window or operating with a lapsed UCR registration exposes you to roadside violations — officers at weigh stations and inspection stops can and do check UCR status. The fee is relatively small, but the consequences of non-compliance are disproportionate.
Frequently Asked Questions
What is UCR registration and who needs it?
UCR (Unified Carrier Registration) is the annual federal registration program for motor carriers, motor private carriers, brokers, freight forwarders, and leasing companies engaged in interstate commerce. Any carrier with a USDOT number that operates across state lines must register and pay the annual UCR fee.
How much does UCR registration cost?
UCR fees are based on fleet size. For the smallest fleets (0-2 vehicles), the fee is typically under $100 per year. Larger fleets pay more, with the highest tier (1,000+ vehicles) running several thousand dollars annually. Exact fees for the current year are published by the UCR Plan at ucr.gov.
When do I need to renew my UCR registration?
UCR registration runs on a calendar year (January 1 through December 31). Enrollment for the next year typically opens in October. Carriers should register as early as possible to avoid operating with a lapsed registration after January 1.
