What must roadway workers do when they hear a train approach warning?

When roadway workers hear a train approach warning, moving to safety immediately is crucial for their protection. This action is essential because approaching trains are often traveling at high speeds, and even a short amount of time can be critical in avoiding a dangerous situation. Roadway workers are trained to respond swiftly to these warnings to ensure that they are not in harm's way, as trains cannot stop quickly and are much larger and heavier than any worker or equipment on the tracks.

Remaining on the track would put workers in jeopardy, as trains can come unexpectedly. Notifying other workers of the warning is important, but the priority must be to ensure personal safety first, as re-routing or communicating can occur after moving to a safe location. Ignoring the warning when it is unclear is also highly discouraged, as it poses a significant risk; it is better to assume safety measures and act without delay than to risk a potentially hazardous situation around unclear signals. Thus, the correct course of action when hearing a train approach warning is to move to safety immediately.
