What does the signal for "move backward" look like?

• A. An arm held straight up with a closed fist
• B. An arm held out directly behind with an open hand facing the operator
• C. An arm raised above the head in a wave
• D. An arm positioned to the side with fingers pointed down

Answer: (B)

The signal for "move backward" is represented by an arm held out directly behind with an open hand facing the operator. This gesture clearly communicates to the operator that the equipment should move in reverse. The open hand signifies that the signal is active and the operator should take action in alignment with the direction shown. Using an open hand ensures visibility and clarity, as it allows the operator to see the signal easily while maintaining a proper line of sight. This is crucial for safety, as it helps prevent accidents that could occur from misunderstandings. The placement of the arm directly behind also provides a visual cue that is unmistakable, distinguishing it from other signals used during operations. In contrast, the other options represent different actions or are signals for other movements that do not convey the intended message of "move backward."
