When backing a heavy vehicle you should not ____.

• A. use a helper and communicate with hand signals
• B. back slowly with a clear line of sight
• C. walk around the vehicle to check clearance
• D. use wheel chocks and trailers

Answer: (A)

Backing a heavy vehicle safely means you stay in control and have a reliable view of what’s behind you. Using a helper and hand signals isn’t dependable because signals can be missed or misread, and the spotter could be in the path of the vehicle as you move, increasing the risk of a collision. The safer approach is to back slowly with a clear line of sight from the cab, using your mirrors to monitor your path and making small, controlled movements so you can stop quickly if needed. Walking around the vehicle to check clearance helps catch obstacles or hazards you might not see from the mirrors. Wheel chocks are used to prevent movement when the vehicle is stationary, and properly securing trailers and connections is another key safety step to minimize unexpected movement.
