What additional requirement comes into effect once a school bus doors are closed?

Once the school bus doors are closed, the primary requirement that comes into effect is that the bus may then start moving. This is an important safety protocol designed to ensure that all students are safely seated before the bus begins to depart from a stop. The operation of the bus in this manner helps to prevent accidents and ensures that students are not in a position to fall or be injured as the bus starts moving.

It's essential to recognize that this procedure is part of the safety protocols in place for school buses to protect children. The closing of the doors signals that the driver has ensured the safety of the boarding process and that it is now appropriate for the bus to leave the stop. While other requirements regarding safety may apply in the general context of riding a school bus, such as enforcing seatbelt usage or ensuring passengers remain seated, the closing of the doors specifically permits the bus to begin moving.
