At what time is the school speed limit typically enforced?

The correct choice reflects the standard times commonly enforced for school speed limits, which are generally set to ensure the safety of children during peak school hours. The period typically stretches from early in the morning when students are arriving until the early afternoon when school dismisses.

In this case, enforcing the speed limit from 0630 to 1400 makes sense as it covers the time when students are arriving for school and leaving in the afternoon, which are critical times for pedestrian safety. This enforcement helps raise awareness for drivers to reduce speed and remain vigilant in areas where children are present. The range selected adequately captures the peak activity around schools, accounting for variability in start and end times across different districts or types of schools.
