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

When drivers encounter a school bus with red lights flashing, they must stop in both directions. This law is in place to protect children who may be getting on or off the bus. The flashing red lights signal that children are either leaving the bus or preparing to board, indicating that drivers should halt their vehicles to prevent accidents.

Stopping is crucial because children may unexpectedly cross the street in front of or behind the bus. Even if there is no traffic coming from the opposite direction, a driver must still stop to ensure the safety of the children. Therefore, this practice not only complies with traffic laws but is an essential safety measure intended to prevent tragic accidents involving schoolchildren.
