What do yellow-red signs warn a train about?

• A. Be prepared to stop because of Planned Work Limits
• B. Stop sign ahead
• C. End of authority
• D. Junction ahead

Answer: (A)

Yellow-red signs target temporary work zones on the track. They signal that planned maintenance or construction limits are in effect ahead, so you should be prepared to stop or proceed under restricted conditions and follow any flagger or dispatcher instructions. This is a caution about a work area, not a direct stop sign or an end of authority marker, nor a junction warning, which is why it’s the best choice here.
