When a school bus has its overhead red lights flashing, what is the required action for drivers?

When a school bus has its overhead red lights flashing, it indicates that children are either boarding or disembarking from the bus, and it is crucial for the safety of those children that drivers take appropriate action. The required action for drivers is to stop no closer than 20 feet from the bus. This distance allows for a safe zone around the bus, protecting children who may be crossing the street or walking near the bus.

Stopping at this distance also complies with state traffic laws designed to enhance the safety of schoolchildren. It's essential for drivers to be aware that failing to stop for a school bus with flashing red lights can result in severe penalties, reflecting the serious nature of the situation.

The other options do not prioritize the safety of the children and could place them at risk. Passing cautiously or continuing to drive at the same speed ignores the law and the possible presence of children. Honking to alert the bus driver is unnecessary and does not contribute to the safety of the situation.
