How must a crew respond to a "flagman" signal according to NORAC?

A crew must respond to a "flagman" signal by slowing down and being prepared to stop as directed by the flagman. This response is crucial because the flagman is positioned to provide specific information or instructions regarding safety, typically in situations where track obstructions or other hazards may be present.

By slowing down, the crew ensures that they have sufficient time to assess the situation and respond effectively to any further instructions from the flagman. This precaution helps maintain safety on the tracks, as it allows for an adequate reaction time in potentially dangerous circumstances.

In contrast, responding inappropriately—such as speeding up or ignoring the flagman’s signal—could lead to hazardous situations, both for the crew and any other trains or workers present on or near the tracks. Thus, the correct response aligns with established safety protocols and the overarching principle of prioritizing safety in operations.
