Warning, Construction & Information SignsStandalone practice
On a rural road, you pass a round yellow sign with a black X and the letters R and R. What should you do?
Correct answer: Slow down, look and listen for a train, and be ready to stop
Why
At the crossing itself, you will see the white X-shaped crossbuck sign, and sometimes flashing lights, a gate or a bell. Check for more than one track, because a second train can come. If your view of the tracks is blocked as you approach, South Dakota law limits your speed to 15 mph within 50 feet of the crossing.
