When are Amber warning lights activated at a stop where red lights are exempt?

Amber warning lights are specifically used to alert other drivers that a school bus is preparing to stop for loading or unloading children. These lights are activated to provide advanced warning to vehicles approaching the bus, particularly in scenarios where the red lights are not in use due to specified exemptions.

In situations where red lights are exempt, such as on certain roadways or under specific conditions where it's safe to stop without needing to activate the full stop signal (red lights), the amber lights serve as a precaution to ensure that drivers are aware of the potential for children getting on or off the bus. Therefore, the amber lights should not be activated if the law specifically dictates that red lights are exempt.

This context highlights that in circumstances where the law does not require the use of red lights, the amber lights should not be used either, resulting in a clear ‘never’ activation at such stops. Understanding this distinction is crucial for school bus drivers to ensure compliance with traffic laws and the safety of the children they transport.
