• A. True
• B. False
• C. Only during daylight
• D. Only with supervisor approval

Answer: (B)

Crossing a tow bar or riding on the outside of moving equipment creates a high risk of serious injury. When the aircraft, tow bar, and tow vehicle are connected, movements can occur suddenly or unexpectedly as steering, braking, or engine power changes apply force to the linkage. A person in or near that area can be crushed, pulled into components, or struck by moving parts. Being on the outside of a moving aircraft or tow bar also puts you in the pinch and crush zones where limbs or clothing can be caught, with little room to react.

Because of these hazards, the safe and correct practice is to stay clear of the tow bar and the outside of the equipment during tow operations, and only approach or cross when everything is secured and the area is controlled according to established procedures. This safety rule holds at all times, regardless of lighting or supervision.
