Show the answer and the explanation

Correct answer: D. Slow down and be ready for stopped traffic ahead.

Why

This yellow warning sign tells you that traffic ahead may be stopped, often at a traffic signal. Slow down, look well ahead, and be ready to stop smoothly. You do not stop at the sign itself. When the stop is at a signal, a Signal Ahead sign with a signal symbol comes first, before this sign.

Why the other answers are not correct

  • A. This is a yellow warning sign, not a STOP sign, so you do not stop at the sign itself.
  • B. The sign warns of stopped traffic ahead, so you slow down instead of speeding up.
  • C. The sign gives you early warning, so you slow down now instead of waiting until the stopped traffic is in view.
