How must hand signals be given?

The requirement for hand signals to be given from a point where they may be plainly seen is crucial for maintaining clear communication between crew members, especially in situations where verbal communication may be inadequate or unsafe due to noise or distance. This ensures that all individuals involved can observe the signals clearly and interpret them correctly, thereby minimizing the risk of misunderstandings that could lead to accidents or operational delays.

Hand signals are a vital part of railway operations, particularly in contexts where visibility is essential for safety. When signals are given from a visible location, it allows both the signaling crew and the receiving crew to maintain a direct line of sight, confirming that the signals are acknowledged and understood. This creates a safer and more efficient operating environment.

Other considerations, such as urgency or personal visibility, are important but secondary to the fundamental principle of visibility of the signal. Signals given in a manner that can only be understood by the train crew may lead to confusion if the crew is not in a position to see or misinterpret the gestures.
