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

When drivers see a school bus with its red lights flashing, they are required to stop regardless of the direction of travel. This law is in place to ensure the safety of children getting on or off the bus. The flashing red lights serve as a visual cue that children may be crossing the street, and stopping is essential to prevent any accidents or injuries.

The law is strict about this requirement; vehicles approaching from both directions must halt. This is especially important in residential areas or near schools where children are more likely to be present. It reflects the commitment to protecting the most vulnerable road users—students—by providing them a safe environment to board and alight from the bus.

For further context, options that involve slowing down, passing with caution, or honking are inadequate responses, as they do not prioritize the immediate safety needs associated with the presence of a school bus with its lights activated.
