For nearly 80 years, American yellow school buses have kept their classic design without factory-standard air conditioning. As extreme heat events become more frequent across the US, the lack of school bus AC has turned from a comfort issue into a public health risk. This article explains the high temperature reality inside school buses, children's higher vulnerability to heat, the absence of federal AC mandates, the cost barrier of AC retrofits, ongoing progress in different states, and the industry trend that air conditioning will gradually become standard equipment for school bus fleets.
