When a school bus driver has another job, whom must they report this to?

The correct choice is that the school bus driver must report another job to the Motor Carrier. This requirement is in place because the Motor Carrier is responsible for regulating and overseeing commercial transportation, ensuring that drivers comply with safety and service regulations. Reporting additional employment helps maintain transparency and ensures that the driver can safely balance multiple responsibilities while adhering to regulations that govern driving hours, safety, and compliance.

The Motor Carrier is also involved in monitoring the overall safety standards within the transportation industry, making it crucial for drivers to keep them informed of any potential conflicts that could arise from additional employment. This helps in assessing the driver's ability to remain alert and proficient while operating a school bus, which is vital for the safety of the students they transport.
