What does the yellow warning sign typically indicating a school represent?
Answer: A — All of the above
The correct answer is A. "All of the above" includes both the statements "You are approaching a school or school crosswalk" and "Slow down, drive with caution and watch for children." In this case, the yellow warning sign indicating a school serves as a reminder for drivers to be cautious, reduce their speed, and be vigilant for children in the area, making both statements true. So, selecting "All of the above" is the correct choice as it encompasses both the specific warnings related to schools.
