Road Signs
A yellow diamond warning sign showing a snake-like S-curve symbol means:
Show Answer & Explanation
Correct Answer: B. Winding road ahead — multiple curves in sequence
A winding-road warning sign indicates several curves close together. Driving these at normal highway speed is dangerous because each curve compounds the previous one's momentum. Slow before the first curve and maintain steady speed through the series.
Why the other answers are wrong
- A.The road contains a sharp single curveA single sharp curve uses a single curved arrow; a winding sign uses an S or repeating curve symbol.
- C.Railway tracks run parallel to the roadParallel railway tracks are not signed with curve warnings; they use railway-specific signage.
- D.Roadwork will cause detoursConstruction detours use orange diamond signs, not yellow winding-curve diamonds.
