The United Carrier Registration system is a federal program that requires businesses operating qualifying commercial vehicles across states or in international trade to register and pay an annual fee. The annual fee depends on the size of a fleet. The UCR program is administered by each base state.
The UCR program also targets businesses that facilitate the transportation of goods, such as leasing and freight forwarding companies. The qualifying motor vehicles include trucks with a minimum gross vehicle weight of 10,001 pounds, passenger vehicles that carry a minimum of 10 passengers and waste-carrying vehicles that have placards. The UCR agreement recognizes power units as the only qualifying vehicles, which excludes trailers. Vehicles operating in interstate trade are also excluded. Each participating state determines how to receive payments for the UCR program. The common accepted modes of payment include online credit card and eCheck payments, while other methods include physical checks and money orders.
The revenues collected through the UCR program are used to implement safety programs for motor carriers. The UCR agreement requires businesses to keep records that validate the information provided in the UCR application. The records should list all vehicles, including vehicles excluded from the UCR filing. The UCR board requires such records in order to audit a business.
