What type of warning system must school buses be equipped with?

School buses are required to be equipped with an 8 lights overhead warning system. This system includes four amber lights that signal a warning when the bus is preparing to stop to load or unload passengers, as well as four red lights that activate when the bus is fully stopped and the doors are opened. The primary purpose of this light system is to alert other drivers and pedestrians of the bus's actions, ensuring the safety of students as they board or disembark.

The use of eight lights provides a clear and visible warning to motorists from all directions, creating a safer environment for children near the school bus. This requirement is crucial in maintaining safety regulations for school transportation and helping to prevent accidents.
