What device is used for relaying signals indicating conditions on the right-of-way?

• A. Flag
• B. Indication
• C. Terminal Indicator
• D. Green Band

Answer: (A)

Relaying conditions on the right-of-way is done with a portable, easily visible signal that a worker can place or hold to communicate with approaching trains. A flag fits this role perfectly: it’s a simple, direct device that a flagger can deploy at any point along the track to tell trains to stop or proceed with caution depending on the situation. It doesn’t rely on fixed infrastructure and is immediately understood by train crews, which is crucial for safety in work zones or where signals are not functioning. The other terms don’t serve as the signaling device used to convey right-of-way conditions. One is a generic term rather than a specific tool, and the others refer to parts or features of fixed signaling systems rather than a portable signaling method used by personnel on the track.
