When repositioning the tow tractor, which action is required to ensure safety?

• A. Set brakes and install chocks
• B. Switch off engine
• C. Remove chocks
• D. Ignore the procedure

Answer: (A)

Preventing movement is the key safety step when repositioning the tow tractor. Engaging the parking brake and placing wheel chocks stops the tractor from rolling, even if controls are momentarily released or if there’s a slight incline. Turning off the engine alone isn’t enough to guarantee full immobilization, and removing chocks or skipping the procedure would remove the physical and control-based restraints that keep people and equipment safe. So, setting brakes and installing chocks is the correct action to ensure safety.
