California Car / Permit practice question · Road Signs
A round, yellow sign with a large black 'X' and the letters 'RR' means:
Answer choices
- A crossroad intersection is ahead
- A railroad crossing is ahead— Correct answer
- Trucks are entering the roadway
- Route marker for a rural road
Why this is the answer
A yellow-and-black round sign, or an X-shaped one, signals a railroad crossing ahead. Look and listen, slow down, get ready to stop, and let every train pass before you cross. It is not a crossroad warning, and you should expect a train on any track, from either direction.
