What must drivers do when they see flashing lights on a school bus?

When drivers see flashing lights on a school bus, they must stop and wait until the lights stop flashing. This requirement is in place to ensure the safety of children who may be entering or exiting the bus. The flashing lights serve as a warning to indicate that children are nearby and that drivers must take extra precautions.

Stopping when the lights are flashing helps prevent potential accidents and allows children to cross the street safely. It's important for drivers to be vigilant and patient in these situations, as children can be unpredictable and may not always be visible until they are on the road.

Continuing to drive at the same speed or making a U-turn would compromise safety, and stopping only if children are present could lead to dangerous situations if a child unexpectedly arrives at the bus. Therefore, the requirement to stop for the flashing lights is a protective measure intended to safeguard children's lives.
