What gesture indicates a proceed signal at a speed of no more than 5 MPH?

The gesture that signifies a proceed signal at a speed of no more than 5 MPH involves holding the hand or a white light steady away from the body. This specific signal is clearly defined in train operation protocols to ensure safe communication between train operators and signalers. By holding the hand or light in a steady position, it conveys a clear and unambiguous message that allows for controlled movement, ensuring that the train operator understands they can proceed while adhering to the speed limit.

Other gestures, though they may convey different meanings in other contexts, do not represent the appropriate signal for this particular scenario. For example, moving the hand in a circular motion is typically used for different instruction, while waving a flag up and down usually communicates an urgent signal. Pointing in the direction of travel might indicate direction but does not specifically address the speed restrictions or the proceed aspect. Thus, understanding the precise meaning of signals is crucial for safety and proper operation in train handling.
