What type of vehicle does OPCF 6B specifically refer to?

OPCF 6B specifically refers to coverage for school buses. This endorsement is designed to address the unique insurance needs associated with school buses, including the transportation of students. School buses have distinct operational characteristics and risks; therefore, the OPCF 6B endorsement ensures that there are adequate protections in place for both the vehicle and its passengers. This coverage often includes special considerations for liability and the specific uses to which school buses are subjected, differentiating it from coverage for other types of vehicles.

The other options represent different categories of vehicles that have their own insurance requirements and regulations, but are not specifically addressed by the OPCF 6B.
