Final answer:
In a posted school zone, you may drive no faster than the speed limit indicated, typically 20 to 25 mph, to ensure the safety of children.
Step-by-step explanation:
In a posted school zone where children are going to or coming from school, the speed limit is typically lowered to maintain safety. Drivers are required to adhere to these limits strictly due to the high presence of children, who are more vulnerable to accidents due to their unpredictable movements and smaller stature. The exact speed limit can vary by location but is often 20 to 25 miles per hour unless otherwise posted or during non-school hours. Authorities may enforce the school zone speed limit with greater strictness, and penalties for speeding in these areas can be severe. It is important for drivers to pay close attention to posted speed limit signs and adjust their driving speed accordingly.
