What action should be taken if backing an ambulance?

Using agreed-upon hand signals while backing an ambulance is crucial for ensuring safety and communication in a potentially hazardous situation. These signals create a clear line of communication between the driver and the individual directing the vehicle. It helps prevent accidents and can alert others in the vicinity of the ambulance's movements. Additionally, hand signals can effectively convey instructions even when noise from traffic or other environmental factors may hinder verbal communication.

In contrast, backing quickly to alleviate traffic can lead to dangerous situations as it may compromise the driver's ability to assess the surroundings. Closing all windows, while it may have some benefits in terms of noise reduction, does not contribute directly to safe backing procedures. Ensuring all lights are turned off is unnecessary and could reduce visibility, which is essential when maneuvering an emergency vehicle.
