What action must drivers take upon stopping for a school bus?

When approaching a school bus that has its red lights flashing and stop signs extended, drivers must come to a complete stop. This is a critical safety measure designed to protect children getting on or off the bus. By stopping fully, drivers ensure that any pedestrians, especially young students who may be crossing the street, have a safe environment to do so.

This rule is in place to minimize accidents and to reinforce the importance of vigilance around school zones. When a bus is stopped with its warning signals activated, it indicates that children are likely entering or exiting the bus, which necessitates caution from other drivers.

The other actions listed—proceeding without stopping, decreasing speed, or honking the horn—do not comply with the safety laws designed to protect children at school bus stops, potentially leading to dangerous situations and legal penalties. It's essential for all drivers to be aware of and adhere to these regulations to promote the safety of students.
