Why are school buses painted yellow and why don t they have any seat belts?

Yellow is the brightest color in the spectrum to human vision. Buses are not built with seat belts, so that's why they don't have them.

They are painted yellow to make them easy to see so that drivers notice them and don't hit them or run over children.

They don't have seat belts for the same reason as a chair in your house or school doesn't: because you aren't in a place dangerous enough to need them, such as a car or an airplane. Trains and school buses, even without seat belts, are much safer than a car, even with seat belts,
