This sign means?

- Narrow road ahead
- Winding road ahead ✓
- Road slippery when wet
- Hidden intersection ahead
Answer: B. Winding road ahead
The sign means winding road ahead.
Why this is the answer
The handbook puts warning signs in the group that warns of possible hazards ahead and gives sharp curve ahead as an example, with the instruction to slow to the advisory speed shown. A winding road ahead warning carries the same kind of message for a road that bends: it alerts you to curves so you can be ready and keep your speed under control. The passages do not spell out the exact sign wording, but the warning-sign section supports this meaning.
Why the other answers are wrong
- A. Narrow road ahead — A narrow road warning would be about a narrow structure such as a bridge, which the handbook lists separately, not about a road that winds.
- C. Road slippery when wet — Road may be slippery ahead is listed as its own warning in the handbook, so it does not mean winding road.
- D. Hidden intersection ahead — The supplied warning-sign passage does not list a hidden intersection sign; the supporting warning list points to curves, not a hidden intersection.
Remember it
Treat a warning sign like a heads-up from a passenger: it tells you what the road is about to do.
