The Unified Carrier Registration Agreement (UCR) applies to you or your business if you operate a commercial motor vehicle in interstate or international commerce. A CMV is defined under Part 49 USC Section 31101, and means a self-propelled vehicle used on the highways in commerce principally to transport passengers or cargo if the vehicle:

  • Has a gross vehicle weight rating or gross vehicle weight of at least 10,001 pounds, whichever is greater.
  • Is designed to transport more than 10 passengers, including the driver.
  • Is used in transporting material found by the Secretary of Transportation to be hazardous under Section 5103 of this title and transported in a quantity requiring placarding under regulations prescribed by the Secretary under Section 5103.
  • Holds an interstate USDOT number and or an active interstate MC number.
  • Engages in interstate commerce but does not leave the state. Example: air freight, river terminals, designated grain elevators, distribution carriers of freight coming from outside the State of Minnesota.
