UCR Guide

Who This Applies To

• Interstate motor carriers (property-carrying, passenger-carrying, or hazmat) required to register annually under the Unified Carrier Registration Plan.
• Freight brokers and freight forwarders engaged in interstate commerce who must complete annual UCR registration as a non-carrier entity.
• Leasing companies that lease vehicles to interstate motor carriers and are subject to UCR registration under the leasing company category.

What To Verify

• Whether the entity type (motor carrier, broker, freight forwarder, or leasing company) is required to register — use the UCR Plan's 'Do I Need to Register' tool to confirm applicability.
• The current registration year's fee bracket based on the number of commercial motor vehicles in the fleet — fee brackets and amounts are set annually by the UCR Plan and must be verified before payment.
• The registration window for the upcoming year — UCR registration typically opens in October and applies to the following calendar year, but deadlines should be verified directly with the UCR Plan.
• Whether any exemptions apply, such as for certain government vehicles, carriers of exempt agricultural commodities, or operations below applicable thresholds.

Step-by-Step Overview

1. Confirm the entity type and check UCR applicability using the official UCR Plan portal at plan.ucr.gov, including the 'Do I Need to Register' wizard.
2. Count the number of commercial motor vehicles in the fleet to determine the correct fee bracket for the applicable registration year.
3. Register through the UCR Plan portal or a participating state agency and pay the fee for the correct registration year — do not use fee tables from third-party or prior-year sources.
4. Retain the registration confirmation for compliance records and make a calendar note for the next annual registration window opening.
5. Review fleet size changes before the next registration year to confirm the correct fee bracket for renewal.

Common Mistakes

• Registering for the wrong calendar year — UCR fees are year-specific and prior-year registration does not carry over to the new year automatically.
• Using an incorrect vehicle count that places the fleet in the wrong fee bracket — over- or under-payment may require correction with the UCR Plan.
• Missing the annual registration window because it opened earlier than expected — the window typically opens in October but the exact date should be verified at plan.ucr.gov each year.
• Assuming that UCR registration through one state covers only that state — UCR is a national program and a single registration covers all participating jurisdictions.
