When crossing a divided highway, who must escort students?

Answer: B — The driver of the bus

The driver of the bus is responsible for escorting students when crossing a divided highway to ensure their safety. As the individual who is in charge of the bus and the children on board, the driver has a primary duty to monitor the surrounding environment and make sure that the crossing is conducted safely. This includes checking for oncoming traffic and ensuring that all students cross at the appropriate times. While a police officer or a crossing guard may assist in traffic control and managing safety in school zones or at crossings, it is ultimately the bus driver's responsibility to ensure that students get across the highway safely. In some situations, other students may not have the authority or training to guide their peers across busy roads safely, making the driver's role even more crucial in these environments.
