Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

A school bus is a type of bus owned, leased, contracted to, or operated by a school or school district. It is regularly used to transport students to and from school or school-related activities, but not including a charter bus or transit bus. Various configurations of school buses are used worldwide; the most iconic examples are the yellow school buses of the United States and Canada.

In North America, school buses are purpose-built vehicles distinguished from other types of buses by design characteristics mandated by federal and state/province regulations. In addition to their distinct paint color (school bus yellow), school buses are fitted with exterior warning lights (to give them traffic priority) and multiple safety devices...

While many changes related to the 1977 safety standards were made under the body structure (to improve crashworthiness), the most visible change was to passenger seating. In place of the metal-back passenger seats seen since the 1930s, the regulations introduced taller seats with thick padding on both the front and back, acting as a protective barrier. Further improvement has resulted from continuing efforts by the U.S. National Highway Traffic Safety Administration (NHTSA) and Transport Canada, as well as by the bus industry and various safety advocates. As of 2020 production, all of these standards remain in effect.

As manufacturers sought to develop safer school buses, small school buses underwent a transition away from automotive-based vehicles. The introduction of cutaway van chassis allowed bus manufacturers to mate a van cab with a purpose-built bus body, using the same construction as a full-size school bus. Within the same length as a passenger van, buses such as the Wayne Busette and Blue Bird Micro Bird offered additional seating capacity, wheelchair lifts, and the same body construction as larger school buses...

For the purposes of evacuation, school buses are equipped with a minimum of at least one emergency exit (in addition to the main entry door). The rear-mounted emergency exit door is a design feature adopted from horse-drawn wagons (the entrance was rear-mounted to avoid disturbing the horses); in rear-engine school buses, the door is replaced by an exit window mounted above the engine compartment (supplemented by a side-mounted exit door). Additional exits may be located in the roof (roof hatches), window exits, and/or side emergency exit doors. All are opened by the use of quick-release latches which activate an alarm.

The number of emergency exits in a school bus is dependent on its seating capacity and also varies by individual state/provincial requirements. The most currently installed is eight; Kentucky requires a rear exit door (or window, for rear-engine buses), a left-side exit door, four exit windows, and two roof-mounted exit hatches...
