What is the role of a ground guide or spotter during backing or maneuvering?

• A. To operate the vehicle's throttle from outside the cab if needed.
• B. To help the driver see hazards and guide safe movement of the vehicle.
• C. To replace the driver's duties entirely during backing.
• D. To direct pedestrians around the vehicle.

Answer: (B)

Backing a vehicle often creates blind spots, so a ground guide fills that visibility gap by watching behind and along the intended path and signaling the driver to move or stop. Their main job is to help the driver see hazards and guide safe movement of the vehicle, using clear hand signals or verbal commands and keeping communication steady so the vehicle can be steered safely and obstacles or pedestrians are avoided. They do not operate the throttle from outside the cab, replace the driver's duties, or direct pedestrians around the vehicle; those tasks are not the spotter’s responsibility and could compromise safety.
