What is the first action a driver must take after deciding on the type of evacuation needed?

Securing the bus is the first crucial step a driver must take after determining the type of evacuation needed. This action involves ensuring the safety of the bus, which may include placing the bus in a safe location away from danger, turning off the ignition, and activating hazard lights. By securing the bus, the driver helps to prevent the vehicle from rolling or other dangers that could expose the passengers to further risk during the evacuation process.

Once the bus is secured, the driver can then proceed with informing students about the evacuation procedure, contacting emergency services if necessary, and leading the passengers out of the bus in an orderly manner. Thus, securing the bus creates a safer environment for both the driver and the passengers before any further action is taken.
