Which sign alerts drivers of a school zone?

The sign that alerts drivers of a school zone is typically labeled as "School Zone Ahead." This sign serves as a warning to drivers to reduce their speed and be especially cautious as they approach areas where children may be present, such as near schools during drop-off and pick-up times. The sign is an essential part of traffic safety, as it highlights the increased risk associated with school zones, particularly when students are arriving at or leaving school.

Other signs related to children's safety, such as those indicating "Slow Children at Play" or "School Crossing," serve specific functions but do not indicate the broader school zone context as effectively as the "School Zone Ahead" sign. "End School Zone" marks the conclusion of the school zone area; therefore, it does not provide advance warning. In the context of driver awareness, the "School Zone Ahead" sign is crucial for ensuring that vehicles are prepared to navigate these potentially hazardous environments safely.
