Who is authorized to make repairs on a school bus or its equipment, unless they are the mechanic responsible for maintenance?

The correct answer indicates that only a mechanic is authorized to make repairs on a school bus or its equipment, aside from the mechanic responsible for maintenance. This underscores the importance of safety and proper training when it comes to maintaining school buses. School buses are equipped with various systems that require specialized knowledge and tools for effective and safe repairs. Mechanics undergo extensive training and certification to ensure they understand the specific requirements and regulations governing school bus maintenance, which is crucial for the safety of the students who use these vehicles.

Other choices do not hold true in this context. For example, allowing bus drivers or anyone else to make repairs could lead to safety issues if they lack the necessary expertise. Similarly, making repairs on the road without the proper authority could compromise both safety and compliance with regulatory standards. Thus, the choice emphasizing that only a mechanic can perform these repairs reflects a commitment to maintaining high safety standards for school transportation.
