Show the answer and the explanationHide the answer
Correct answer: A. Slow down and be ready to follow a flagger's signals ahead.
Why
The Flagger sign warns that a flagger is ahead, controlling traffic through a work zone. Slow down, watch for the flagger, and be ready to stop. Obey the flagger's signals: a STOP paddle means stop, and a SLOW paddle means go on slowly with care. A Workers sign looks similar but shows a person with a shovel; it warns of workers in or near the road, not a flagger.
Why the other answers are not correct
- B. Wrong: a work area with a flagger calls for a lower speed and full attention, not a faster pass.
- C. Wrong: the sign is placed in advance of the flagger; you stop where the flagger signals you to stop, not at the sign.
- D. Wrong: the orange color and the flag show a flagger in a work area, not a school crossing guard.
