At bus stops where more than one child is unloaded, what procedure helps prevent unloading accidents?

The procedure of counting students as they disembark and recounting them before moving the bus is essential for ensuring that all children are safely unloaded. By counting the students as they exit, the driver has a clear visual confirmation of how many children have left the bus. Recounting before the bus departs ensures that no child remains on the bus unnoticed, thereby reducing the risk of accidents that may occur if a student inadvertently stays on the bus or if a child runs back to retrieve an item. This method emphasizes accountability and vigilance on the part of the bus driver, fostering a safer unloading environment.

The other options, while they might seem helpful at a glance, don't provide the same comprehensive procedural safety as counting does. Allowing only one student to leave at a time can be impractical in busy situations and may lead to delays or frustration. Shouting names could create confusion and does not guarantee that all students are accounted for. Installing a camera could assist in monitoring, but it does not replace the need for the driver's active engagement and assessment of the unloading process.
