It is a matter of safety.
Millions of little children are transported in yellow carriages that they call school buses every day to school. But have you ever wondered why are all school buses yellow in color? Does it bring out a specific attribute just like a uniform brings to a school? Or is it to give attention to the headlights?
Neither of them. School buses should be yellow color as per the law. Along with other safety measures taken for school going children, the school buses were made yellow for a matter of safety. But there's something else to it.
Then one strict shade that resembles the skin of a mango was considered the only valid color for a school bus.
In 1939, Dr. Frank W. Cyr organized a meeting to discuss the standard color for school buses.
It is said that yellow color is more identifiable as compared to red from a distance.
Normally, people think that red is a more vibrant color, and people are more attentive to red. But that's not true.
That's why it's easy to identify school buses even during foggy mornings.
