What must drivers do when they see a school zone sign?

Answer: C — Reduce speed and watch for children

When drivers encounter a school zone sign, reducing speed and being vigilant for children is crucial for ensuring safety. School zones are designated areas where children may be present, either arriving at or departing from school. This increased pedestrian activity necessitates a lower speed limit to give drivers more time to react to any unexpected movements from children or school crossing guards. Maintaining a slower speed allows for better visibility and reaction time, which is essential in preventing accidents. Additionally, school zones often have specific speed limits, typically lower than surrounding areas, to enhance safety. Awareness of children walking or biking in these areas is also critical, as they may not always be predictable in their actions. Meanwhile, ignoring the speed limit, maintaining current speed, or speeding up to clear the area can lead to dangerous situations, as they compromise the safety of children. Therefore, reducing speed and being alert is the most responsible action for drivers in school zones.
