Which role is trained to provide at least 15 seconds of warning to roadway workers?

• A. Roadway Worker
• B. Watchman/Lookout
• C. Job Briefing
• D. Marker

Answer: (B)

The Watchman/Lookout is the person trained to give at least 15 seconds of warning to roadway workers. This role is placed to observe approaching trains and communicate a timely warning to the crew, often using a whistle, flags, or other signaling means. That 15-second lead time is designed to give workers enough time to clear the tracks or take protective action before a train arrives, keeping everyone safe in the work zone. The other options don’t carry this specific warning responsibility: a roadway worker is the person doing the on-site tasks, a job briefing is the pre-work safety discussion, and a marker is used to designate locations rather than to warn about an approaching train.
