What sign indicates a school zone?

The sign indicating a school zone is specifically designed to alert drivers that they are approaching an area where children may be present, and it typically includes the words "School Zone" along with specified speed limits. This sign is crucial for ensuring safety because it informs drivers to reduce their speed to protect children who may be crossing the street or boarding or disembarking from school buses. The inclusion of speed limits in school zones is particularly important, as it emphasizes the need for extra caution in these areas where traffic patterns can change rapidly due to the presence of students.

Other options may point to important traffic controls, but they do not specifically denote a school zone. For instance, signs that indicate "Stop" with flashing lights are used in various contexts but do not necessarily indicate the proximity of a school. A pedestrian crossing sign alerts drivers to areas where pedestrians may be present, but it lacks the specificity of a school zone sign. Additionally, red signs indicating speed limits might apply to various road conditions but do not specifically signal a school zone. Therefore, the "School Zone" sign is the most accurate representation of warning drivers about the presence of a school and the associated need for reduced speed.
