Who is responsible for ensuring school bus riders wear seat belts?

Answer: B — The bus driver

The responsibility for ensuring that school bus riders wear seat belts primarily falls on the bus driver. As the individual in charge of operating the vehicle and ensuring the safety of all passengers, the bus driver plays a critical role in monitoring seat belt use. While bus monitors and other personnel may assist in reinforcing safety protocols, ultimately, it is the driver's responsibility to enforce these rules and ensure compliance among students. Regarding the other options, while parents are crucial in teaching their children about safety and the importance of wearing a seat belt, they are not present on the bus to enforce these rules. The school administration might implement policies regarding safety, but the immediate enforcement of these policies, particularly regarding seat belts on the bus, is the driver's duty.
