Which statements about hand signals used on a jobsite are correct?

• A. II only
• B. I only
• C. I and II
• D. Neither I nor II

Answer: (A)

Hand signals on a jobsite are standardized methods used to communicate with equipment operators when voice communication isn’t effective. The key point is that signals must be agreed upon, taught, and understood by both the signaler and the operator, so interpretations are consistent and hazards are minimized. Signals should be given with a clear line of sight, and everyone involved should be trained on the approved set, often reinforced with a posted signaling chart and pre-job briefings. Radios can supplement communication, but hand signals should be based on a standard, practiced set, not improvised or ambiguous gestures. If one statement aligns with these practices—emphasizing standardization, training, and mutual understanding—while the other does not, that explains why only that one is correct.
