Which statement describes the proper use of a ground guide during backing?

• A. The ground guide is there to replace the driver’s duties entirely.
• B. The ground guide helps the driver see hazards and guide safe movement.
• C. The ground guide should operate the vehicle’s controls.
• D. The ground guide should stay inside the vehicle at all times.

Answer: (B)

Backing a vehicle, especially an emergency vehicle, relies on a clear, outside observer to keep the driver aware of hazards and to guide the vehicle's movement. A ground guide serves that purpose by spotting obstacles, pedestrians, or other hazards in the path and signaling the driver on how to move safely. The driver still controls speed, steering, and braking—the ground guide does not replace those duties.

For this to work well, the ground guide should be outside the vehicle, in a position with a clear view of the rear and sides, facing the driver to communicate with hand signals or radios. They must not touch or operate any of the vehicle’s controls, and they should stay out of the vehicle’s path while backing. This collaboration is what makes backing safer than relying on the driver alone.

The other options aren’t appropriate because the ground guide isn’t there to take over driving, operate controls, or stay inside the vehicle; those duties remain with the driver, with the ground guide providing external visibility and direction.
