The speed limit on roads near high schools can vary, but in many areas, the speed limit is typically around 25 to 35 miles per hour. This is because high traffic areas near schools require lower speed limits for the safety of students and pedestrians. It is important to always obey posted speed limit signs and drive cautiously in school zones.
A speed limit sign with flashing yellow lights is known as a "flashing speed limit sign" or "dynamic speed display sign." These signs are designed to alert drivers to adjust their speed, particularly in areas where conditions may warrant a lower speed, such as near schools or construction zones. The flashing lights serve to capture attention and enhance safety by emphasizing the importance of adhering to the posted speed limit.
