What is the standard for exterior lights specific to orange and red colors?

The standard for exterior lights specific to orange and red colors designates that 8-way amber lights indicate caution and are used primarily for school zones to alert other drivers about the presence of children. The 8-way red lights serve a critical safety function by stopping traffic when a school bus is loading or unloading children. This system is intended to provide clear communication to other drivers regarding the bus's actions, ensuring the safety of children. Therefore, having both amber and red lights specified ensures that other vehicles are adequately signaled to either slow down or stop, depending on the situation.

In this context, the correct answer effectively highlights the significance of these two colors in maintaining safety regulations for school buses. The other options do not align with established regulations regarding school bus lighting, as they either do not provide the necessary warning signals or misstate what lights are required.
