What action must a school bus driver take if the bus breaks down?

Answer: B — Stay with the bus and follow emergency procedures

A school bus driver must stay with the bus and follow emergency procedures if the bus breaks down. This approach is crucial for several reasons. First, the bus serves as a safe haven for the children onboard. Leaving the vehicle could expose them to potential dangers, especially if they are in traffic or an unsafe location. By remaining with the bus, the driver can ensure the safety and security of all passengers. Additionally, following established emergency procedures ensures that the situation is managed correctly, which typically includes signaling for assistance, using hazard lights, and communicating with dispatch or emergency services as necessary. These protocols are designed to minimize risks and protect the safety of both the children and the driver, making it vital to adhere to them. The other options, while well-intentioned, do not prioritize the safety of the children onboard or follow proper protocol in a breakdown situation.
