Unified Carrier Registration (UCR)

Introduction

The Unified Carrier Registration (UCR) program is a federal initiative managed by the Federal Motor Carrier Safety Administration (FMCSA) that requires motor carriers, brokers, freight forwarders, and leasing companies operating in interstate and international commerce to register annually with a participating state and pay fees based on fleet size or business role. Created by Congress in 2005 to replace the Single State Registration System, the UCR aims to streamline the registration process and fund state motor carrier safety and enforcement programs across 41 participating states. The program applies to for-hire, private, and exempt carriers, including those based in Canada and Mexico operating in the U.S., with specific exemptions defined by the UCR Agreement.

UCR fees vary by fleet size, with rates for small operations starting around $46 and scaling up to tens of thousands of dollars for the largest fleets, while brokers and freight forwarders pay fees based on their roles rather than vehicle counts. After several years of fee reductions, UCR fees increased by about 25% in 2025 to better fund safety programs without reaching pre-2019 levels. Compliance is mandatory, with enforcement including roadside inspections, fines, and operating authority suspension for non-compliance. The registration period opens annually on October 1 and closes December 31, with many carriers opting into auto-renew programs to simplify compliance.

The UCR program's continuous updates include clearer enforcement guidelines and increased education efforts through initiatives like the Unified Carrier Registration Awareness campaign, aiming to maintain high compliance rates and enhance safety oversight in the motor carrier industry. Support and resources are available for carriers and brokers via official UCR helpdesks and authorized service providers to assist with registration and compliance processes.

What is the UCR?

The Unified Carrier Registration (UCR) Plan is a federally mandated, state-administered annual registration and fee system for commercial motor carriers engaged in interstate commerce. It replaced the old Single State Registration System (SSRS) in 2007. The UCR is managed by the UCR Board, established under the U.S. Secretary of Transportation.

Purpose of the UCR

Its primary purpose is to generate revenue that funds state programs for commercial motor vehicle safety and enforcement. Unlike safety rating systems, the UCR is strictly a fee collection mechanism for supporting these programs.

How UCR Differs from Other Registrations

The UCR is distinct from the International Registration Plan (IRP), which covers vehicle registration, and the International Fuel Tax Agreement (IFTA), which deals with fuel taxes. UCR focuses solely on funding safety-related state activities tied to commercial interstate operations.

Who Must Register?

Entities required to register annually under the UCR include:

• For-hire motor carriers (trucking companies hauling goods for others)
• Private motor carriers (companies hauling their own freight interstate)
• Freight forwarders
• Brokers
• Leasing companies operating commercial motor vehicles interstate

The UCR applies to entities that hold a USDOT number and operate in interstate commerce across the 50 U.S. states and the District of Columbia.

Who is Exempt?

• Carriers operating exclusively in intrastate commerce
• Companies designated as “New Entrants” exempt during their first year of operation but required to register after
• Certain agricultural carriers meeting specific conditions

UCR Fee Structure (2024-2025 Data)

Basis for Fees:

UCR fees are calculated based on the total number of commercial motor vehicles (power units) a carrier operates across its entire fleet, regardless of how many states the vehicles operate in. Fees are paid once annually.

2024 Fee Schedule (consistent with 2023):

• 0–2 vehicles: $59
• 3–5 vehicles: $220
• 6–20 vehicles: $439
• 21–100 vehicles: $2,387
• 101–1,000 vehicles: $22,587
• 1,001+ vehicles: $225,887

Special Note for Brokers and Freight Forwarders: These entities pay the lowest fee tier (0–2 vehicles) because they do not own power units, resulting in a 2024 fee of $59.

2025 Fee Changes: The Federal Motor Carrier Safety Administration (FMCSA) approved an average 25% increase in fees for 2025 after prior decreases and fee stability in previous years. Representative 2025 fees include:

• 0–2 vehicles: $46 (smallest fleets & brokers)
• 3–5 vehicles: $138
• Largest bracket (1,001+ vehicles): $44,836

Note: The decrease in the smallest bracket from 2024 to 2025 reflects fee recalibration and statutory revenue caps.

Fees are federally capped by law. The UCR Board adjusts fees up or down annually to ensure total revenue meets but does not exceed the cap, explaining periodic fee volatility.

Registration & Payment Process

• Registration Period: The UCR registration year runs October 1 - September 30, with fees due by December 31 of the previous calendar year (e.g., 2025 registration fee due by Dec 31, 2024).
• Base State Registration: Carriers register through their base state — where their principal place of business is located. If that state does not participate in UCR, registration can be done through any participating state.
• How to Register: Via the official UCR portal UCR.gov or participating state websites, linked from the UCR Plan site.

Enforcement & Penalties

• Enforcement Authorities: State law enforcement officers (DOT officers), state motor vehicle agencies, and groups like the Commercial Vehicle Safety Alliance (CVSA) enforce UCR compliance during roadside inspections and audits.
• Penalties for Non-Compliance: Fines can range from $300 to over $5,000 per violation depending on the state and circumstances. Vehicles can be placed out-of-service until compliance is verified. Penalties may be assessed per vehicle or per violation.
• Broker and Shipper Liability: Brokers and shippers may face legal risks (“negligent selection” liability) if they hire or contract with carriers lacking proper UCR registration. Some states are increasingly focusing on broker accountability.

Common Pain Points & Misconceptions

• “I have IRP, so I’m covered.” — False. UCR is separate from IRP and IFTA.
• “New carriers don’t need to register.” — New Entrants are exempt only their first year. Registration is mandatory thereafter.
• “Small fleets don’t need to worry.” — False. Enforcement targets all sizes; fines are high relative to fee cost.
• “I operate in just a few states.” — UCR applies to all interstate commerce regardless of the number of states involved.
• “Confusion over fleet size.” — All owned, leased, and controlled power units counting toward fleet size must be included.
• “Uncertainty about base state.” — The base state is the principal place of business; multi-location operations may need guidance.

Industry Data & Trends

• Revenue Generated: The UCR system generates over $100 million annually to fund state commercial motor vehicle safety programs.
• Participation: Currently, 41 states participate. Arizona, Florida, and a few others do not participate; carriers there must register through a participating state.
• Digital Integration Efforts: Industry and regulators are pushing for streamlined digital compliance tools for easier registration, verification, and broker accountability.
• Stable Fees with Periodic Adjustments: Fees have stabilized recently but adjusted upward in 2025 due to revenue caps imposed by federal law.
• Audit Focus: UCR compliance is a standard check during state and federal motor carrier compliance audits.

Actionable Guidance by Audience

Carriers / Drivers:

• Accurately count your fleet size including owned and leased vehicles.
• Identify your correct base state for registration.
• Register and pay fees by December 31 prior to the registration year.
• Keep proof of registration (no decals issued) in your vehicle for inspections.
