Why must a school bus driver activate the amber (yellow) warning lights a set distance before a stop, rather than only the red lights right at the stop?

Pick an answer

1. Amber lights give approaching traffic advance notice to begin slowing down before the bus actually stops
2. Amber lights are used only at night, never during daytime stops
3. This requirement applies only on roads with a speed limit above 50 mph
4. Amber lights are purely decorative and serve the same function as the red lights, so either color can be used
