Crew must notify the locomotive operator of a condition requiring slowdown or stop within what distance before reaching the condition?

• A. Not more than five miles, but not less than two miles.
• B. Not less than ten miles.
• C. Not more than three miles.
• D. Not more than one mile.

Answer: (A)

When there’s a condition that requires slowing or stopping, the crew needs to give the locomotive engineer a timely heads-up so the engineer has room to react. The standard directive requires notifying within a window of two to five miles before reaching the condition. This range provides enough lead time for the engineer to begin braking or adjust speed safely, without signaling too far in advance where the information might no longer be relevant. If you inform more than five miles away, the notice is premature; if you inform closer than two miles, the window isn’t met, leaving insufficient time for coordinated action. The other distances don’t fit this required window, so the correct choice is the one that matches the two-to-five-mile range.
