Show the answer and the explanation

Correct answer: A. A sharp low spot in the road surface ahead.

Why

This sign warns of a sharp low spot in the road ahead. Slow down before you reach it so that you keep control and do not jolt your vehicle. If a speed plaque is below the sign, use that speed as a guide. The BUMP sign has the same shape and color, but it warns of a sharp rise in the road instead.

Why the other answers are not correct

  • B. Wrong: a sharp rise in the road is shown by the BUMP sign, not the DIP sign.
  • C. Wrong: a change from pavement to gravel is shown by the PAVEMENT ENDS sign.
  • D. Wrong: a drop-off at the road edge is shown by a shoulder sign; this sign is about the road surface in your lane.
