Explanation:
A pentagonal (five-sided) sign typically indicates a school zone ahead. This type of sign is used to alert drivers to a nearby school so that they exercise extra caution and slow down, often during specific times when children are most likely to be entering or leaving the school premises. Drivers need to adhere to the posted speed limit signs within a school zone to ensure the safety of students and pedestrians.
