What action should a driver take when they notice a child approaching the bus?

When a driver notices a child approaching the bus, signaling the child to wait until it is safe is the most appropriate action. This response emphasizes the importance of ensuring the child understands that they should not approach the bus until it is safe to do so. Children may not always recognize the potential dangers of moving traffic or may not be aware of how to safely board the bus. By signaling them to wait, the driver actively engages in a precautionary measure to prevent accidents and ensure the child’s safety.

Turning on the flashing lights is a useful action, as it indicates that the bus is either stopped or preparing to stop, thereby warning other drivers to be cautious. However, it does not provide direct communication or assurance to the child regarding their timing to board the bus. Honking the horn may initially attract the child's attention but does not convey a clear message about safety or waiting until it is safe. Lastly, waiting for the child to board without hesitation does not take the necessary steps to verify that the child is aware of their surroundings or that it is indeed safe for them to approach the bus.
