There are 2 definitions of a commercial motor vehicle that apply to the UCR Agreement.
The first definition determines whether the company files a UCR application due to the change in the federal definition of a motor carrier or motor private carrier.
The second definition of a commercial motor vehicle used under UCR is taken from section 31101 for the payment of fees. These two definitions are the same for freight operations and transporting hazardous materials but differ for passenger operations.
These definitions reference the transportation of property and passengers using a commercial motor vehicle as defined under section 31132.
Section 31132 is designed or used to transport:
More than eight passengers, (including the driver, for compensation
More than 15 passengers, including the driver not or compensation.
Section 31101 is designed or used to transport more than 10 passengers.
The difference in the number of passengers may mean that a company needs to file a UCR application but may not have any vehicles to report and pays the lower tier fee.
