Which statement about hand signals on a jobsite is true?

• A. The signals are different for every type of machinery.
• B. Signals must be clearly understood by the signal person and the operator.
• C. Signals are not standardized.
• D. Signals are optional.

Answer: (B)

Clear, standardized hand signals between the signal person and the operator are essential on a jobsite. In noisy environments, verbal cues can be missed, so the operator relies on the signaler’s gestures to move or stop equipment safely. Because of that, the signals must be clearly understood by both parties to ensure the machine responds exactly as intended and at the right time. Training and safety standards establish a common set of signals so crews can communicate consistently across different machines and sites, reducing the risk of miscommunication and accidents. These signals aren’t optional, and while some tasks may involve additional gestures for specific equipment, the core requirement is that the signaler and operator share a mutual, standardized understanding.
