Which horn sound is used for approaching roadway workers or their equipment on or near the track, regardless of whistle prohibitions?

• A. The horn sound for When stopped, back up.
• B. The horn sound for Approaching Roadway Workers or their equipment on or near the track, regardless of any whistle prohibitions.
• C. The horn signal for Acknowledgement of a Stop Signal other than a fixed signal.
• D. The horn sound for When running, stop at once.

Answer: (B)

The key idea is that there is a dedicated horn signal specifically to warn roadway workers and their equipment when they are on or near the track, and this signal must be used even if whistle bans are in effect. This exception is all about safety—workers can be in the danger zone, so a distinct audible warning is required to ensure they hear an approaching train in time to move to safety or protect themselves. Because protecting workers takes precedence, that horn sound is used regardless of any whistle prohibitions. The other horn signals serve different purposes (such as backing up from a stopped position or acknowledging signals or stopping at a signal), but they are not the established warning when roadway workers are present.
