This sign means?
- Road slippery when wet
- Hidden intersection ahead
- Narrow road ahead
- Winding road ahead ✓
Answer: D. Winding road ahead
This sign warns of a winding road ahead.
Why this is the answer
The handbook's list of common warning signs includes an entry for a winding road ahead, and it treats that as a separate sign from the ones for a slight bend or curve in the road and for a sharp bend or turn. Warning signs like these alert you to a road condition coming up so you can adjust before you reach it. Since the sign in the picture is the one that means winding road, that is the meaning to choose.
Why the other answers are wrong
- A. Road slippery when wet — The handbook's warning-sign list does not include a slippery-when-wet sign, so nothing in these passages supports that meaning.
- B. Hidden intersection ahead — A hidden intersection sign is listed separately and refers to drivers on a sideroad who cannot get a clear view of traffic, not to the shape of the road.
- C. Narrow road ahead — A narrowing road is covered by the separate pavement-narrows-ahead sign, which is a different warning from the winding road one.
Remember it
Winding means a stretch of curves one after another, so separate it in your mind from the single-curve and sharp-turn signs.
