True or false: Any object waived violently by a person on or near the track is a signal to stop.

The statement that any object waived violently by a person on or near the track is a signal to stop is true. In railroad operations, unusual or violent motions made by individuals in close proximity to the tracks typically indicate an emergency or a need for immediate action. Such signals are crucial for alerting train crews to impending danger or hazardous situations that require them to halt their progress for safety reasons. This operating practice safeguards both the crew and any potential passengers by facilitating quick responses to unexpected situations.

Other potential interpretations, such as the type of object or additional verbal commands being required, do not align with the established protocols, as the visual alert itself serves as a sufficient signal under typical circumstances.
