You see this sign on a rural road. What should you expect ahead?

Yellow diamond sign with a black border and a black arrow that winds left and right as it points up.
  1. AA single sharp turn, then a long straight road.

Show the answer and the explanation

Correct answer: D. A series of three or more curves close together.

Why

This is the Winding Road sign. It warns that the road ahead has three or more curves close together. Slow down before the first curve and keep a safe speed until the curves end, because you may not see far ahead. A plaque such as NEXT XX MILES can show how far the curves go on. The Reverse Curve sign looks similar, but its arrow bends only twice and warns of two curves.

Why the other answers are not correct

  • A. One sharp turn is shown by the Turn sign, an arrow with one square bend.
  • B. Two curves in opposite directions are shown by the Reverse Curve sign, an arrow with two bends.
  • C. Hills and dips have their own signs; this winding arrow shows the road bending to the left and right.
