What does an amber flashing signal light indicate?

The amber flashing signal light indicates caution and instructs drivers to reduce speed. This signal is commonly used on school buses to alert other motorists that the bus is either stopping or preparing to stop for the purpose of loading or unloading children. By reducing speed, drivers can ensure they are prepared to stop safely if the bus comes to a halt. This precaution helps protect the safety of children entering or exiting the bus, as well as ensuring that bus drivers can carry out these actions without the risk of accidents. Understanding this signal is crucial for both school bus drivers and other motorists to maintain safety around school zones and during bus operations.
