Show the answer and the explanationHide the answer
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.
