Which form documents stop and flag protection?

• A. Form A
• B. Form B
• C. Form D
• D. Form C

Answer: (C)

Stop and flag protection relies on a clear, written instruction that tells train crews to stop and flag past a work area to shield personnel on or near the tracks. The form used to document this specific protection is Form C. It records where the protection is in effect, the time window, the flaggers involved, how trains are to be signaled, and who to contact for authorization or changes. This written record ensures everyone on the railroad understands exactly where and when trains must stop and how they should be flagged, reducing the risk of a train entering an active work zone. Other forms cover different protections or situations, so Form C is the one designated for stop-and-flag protection.
