Did You Know? School Buses Are Yellow Because It's the Easiest Color to See!

School Buses Are Yellow for a Scientific Reason! 🚌

Ever wonder why ALL school buses are the same yellow color? It’s because yellow is the color that humans can see fastest, even in their peripheral vision!

In 1939, educator Frank Cyr organized a conference that standardized the school bus color to “National School Bus Glossy Yellow.” This specific yellow was chosen because people notice it 1.24 times faster than red — which is important for keeping kids safe. It’s also highly visible in dawn, dusk, rain, and fog.

Color a school bus in its special yellow, then try drawing it in other colors to see which stands out most! Ask your kids: “If you could change the school bus to any color, what would you pick?”

Fun fact bonus: There are about 480,000 school buses in the United States — they carry 26 million children every day, making it the largest mass transit system in the country! 🎒
