What is one requirement for school buses regarding inspections?

School buses are required to be inspected annually to ensure they meet safety standards and are in safe operating condition. This requirement is crucial because school buses carry children, and ensuring their safety is of utmost importance. The annual inspection includes checks on various safety features, such as lights, brakes, tires, and the overall mechanical condition of the vehicle, helping to prevent accidents and ensure that the buses are reliable for transporting students.

The other options do not reflect the requirements for school bus inspections appropriately. While registration with the DMV is necessary for all motor vehicles, including school buses, it is not specific to the inspection requirements. Emissions tests may apply to certain vehicles depending on local regulations, but they are not a requirement specifically for school buses in Pennsylvania. Lastly, school buses are not exempt from inspections; in fact, they are subject to stricter inspection standards due to the nature of their operation.
