What is a primary purpose of a school zone sign?

The primary purpose of a school zone sign is to alert drivers to the presence of a school or marked school crossing. These signs are critical for enhancing safety in areas where children are likely to be walking or crossing the street, typically near schools. They serve as a reminder for drivers to reduce their speed and remain vigilant, as children may be unexpectedly crossing the road or walking in the vicinity.

With the increase in foot traffic during school hours, these signs play an essential role in ensuring that drivers are aware of their surroundings and ready to react appropriately to any situations that may arise, thereby helping to prevent accidents and protect young pedestrians.
