What speed must you travel in a school zone only when indicated by a sign or signal?

In a school zone, the speed limit is generally set to ensure the safety of children and pedestrians. When indicated by a sign or signal, the appropriate speed is typically 25 miles per hour, which allows drivers to react swiftly in case of unexpected situations, such as children crossing the street. This limit is established to reduce the risk of accidents and to promote a safer environment during times when children are arriving at or departing from school.

While some jurisdictions might have varying limits, the 25 mph speed limit is a commonly recognized standard in school zones across many areas, including Virginia. Therefore, understanding and adhering to this speed when indicated is crucial for maintaining safety in school zones.
