What does a school zone sign indicate?

A school zone sign indicates a reduced speed limit when children are present, making it crucial for drivers to slow down and remain vigilant. The presence of children near schools increases the risk of accidents, particularly when they are entering and exiting school grounds or crossing the street. Therefore, these signs designate specific areas where drivers should be extra cautious and adhere to lower speed limits to ensure the safety of students.

The focus on reduced speed limits in school zones is based on the awareness that children may not always be fully attentive to their surroundings, and sudden stops or quick adjustments might be required. Thus, it's important for drivers to be aware of these signs and to comply with the posted speed limits, especially during school start and end times when children are likely to be present.
