School zone speed limits are typically enforced during drop-off and pick-up times to ensure the safety of children arriving at or leaving school. The correct answer is D, 7 a.m. to 4:30 p.m., as this timeframe covers the usual window of increased pedestrian and vehicular traffic around schools. It is essential for drivers to be aware of and adhere to these specific hours to prevent accidents and promote a safe environment for everyone in the school zone.
