What does a yellow and black circular or X-shaped railroad sign mean?
- You must stop only if gates are lowered
- A divided highway begins after the tracks
- A train has already cleared every track
- A railroad crossing is ahead, so look, listen, slow down, and prepare to stop
Answer: A railroad crossing is ahead, so look, listen, slow down, and prepare to stop. A yellow and black circular or X-shaped sign warns that a railroad crossing is ahead. Gates lowered is only one possible active warning; the sign itself calls for looking, listening, slowing, and preparing to stop before any train appears. The cue is the round yellow advance sign or X marking. Reduce speed, scan both directions, and let any trains pass before crossing the tracks.
