Six School Bus Facts

School buses are yellow everywhere except for the roof. The reason is that white tops are more reflective, lowering the temperature inside the bus by an average of 10 degrees during the summer.

School bus yellow is a color that was specifically formulated for use on school buses in North America in 1939. The color was chosen because it attracts attention and is noticed faster than any other color.

White Strobe lights are supposed to make the bus more visible to other motorists. If your bus has one, it must be on while transporting students to and from school. Some states require newer buses to have one, and it has to be on at all driving times. Rules differ from state to state.

Onspot chain systems are a set of built in chains that can be released to provide traction on icy roads. The chains look like a small octopus that hangs next to the rear wheels of the bus. They are fixed to the bus’ suspension and when required are engaged by a button on the dashboard. Many fire trucks and ambulances use the same type of chains.

The cost of adding seat belts to school buses outweighs any potential benefits, according to NHTSA studies. Modern school buses are large and heavy, and their passengers sit high off the ground. School buses are designed to be safe.

The tiny holes in the ceiling surface absorb sound energy, keeping the bus quieter than it would be otherwise. The mechanism is similar to that used by many acoustical tile products, such as dropped-ceiling tiles.
