Which of the following signifies that you are near a school zone?

The presence of a yellow flashing light is a clear indication that you are approaching a school zone. This type of signage is strategically used to alert drivers to slow down and be cautious, as children may be crossing the street or walking near the road during school hours. School zones often have specific speed limits, and the yellow flashing light helps emphasize the need for increased awareness and reduced speed in these areas.

While other options like stop signs and painted crosswalk lines are important traffic control devices, they do not specifically signify that you are in or near a school zone. A stop sign indicates where to come to a complete halt, and painted crosswalk lines signal designated crossing points for pedestrians. Curb painting can vary in meaning and is not a standardized indicator of school zones. The yellow flashing light serves as a universal and effective warning system specifically linked to school zones, making it the correct recognition for this situation.
