In a school zone, when must a driver stop?

In a school zone, a driver is required to stop whenever directed by a signal or crossing guard. This is important because crossing guards are trained to ensure the safety of children as they navigate busy streets during school hours. They play a critical role in managing traffic to safeguard young pedestrians, and their instructions are designed to create a safer environment for children who may be crossing the street before or after school.

Other considerations, such as stopping only when children are present or during certain hours, do not account for the variability of school activities or the potential presence of children waiting to cross. Similarly, while stopping at all times may seem like a safe approach, it could lead to unnecessary congestion and confusion in areas where no guard is present or where the signal indicates it's safe to proceed. Stopping only when school is in session also overlooks the importance of making the area safer during all times that children may be near the school, which can include after-school activities or special events.
