There is no UCR Agreement credential requirement. The UCR Act generally prohibits states from requiring interstate motor carriers, motor private carriers, freight forwarders, or leasing companies to display UCR credentials in or on their commercial motor vehicles.
The Tennessee Department of Revenue will provide a receipt to the registrant when they register for UCR through this office. Enforcement officers will be able to independently determine the UCR status of a motor vehicle. Motor vehicle registrations may be viewed online at the FMCSA website at: http://safer.fmcsa.dot.gov/ under Unified Carrier Registration (UCR) or at https://www.ucr.gov/.
