Sample question from test 5
signs
What does a yellow plus-shaped crossroad sign warn of?
- A cross road ahead
- A divided highway ending
- A speed limit beginning
- A railroad gate ahead
Answer: A cross road ahead. The plus-shaped warning sign corresponds to Cross Road Ahead in South Dakota's warning sign examples. A railroad gate warning uses railroad symbols and signs, not the plus-shaped road-intersection symbol. Use the crossroad cue to search left and right earlier than usual, cover the brake if visibility is limited, and expect vehicles that may enter or cross your path. Crossroad warnings matter most on rural highways where cross traffic may not have a stop sign visible to you.
