When should you stop for a school bus?

Stopping for a school bus is governed by laws designed to protect children as they enter or exit the bus. The correct response highlights that a driver must stop when the school bus has its stop sign extended and its red lights flashing. This is a clear indication that children may be crossing the street to board or exit the bus, making it essential for vehicles to come to a complete stop to ensure their safety.

When the stop sign is extended and the red lights are activated, it legally requires vehicles traveling in both directions on a two-lane road to stop unless there is a physical barrier. This rule is in place to prevent accidents and ensure that children have a safe passage.

Other scenarios, such as waiting only until children are visible or reacting to the bus driver's signals, do not provide the same level of safety assurance because they may not account for children who may unexpectedly cross the road at any time. Additionally, stopping when the bus is merely pulling over makes little sense since this does not guarantee that children are nearby or in need of protection. Following the correct option is crucial for the safety of schoolchildren.
