At the end of a route or an activity trip, what does a school bus post-trip inspection look for that a general commercial vehicle post-trip would have no reason to?

Explanation

A school bus post-trip hunts for children asleep in the seats and belongings left behind, and checks the gear that only a school bus carries, meaning its stop signal device, its external mirror system, and its warning lights. The driver covers the aisle and then the outside of the bus, also looking for windows and doors left open and for damage or vandalism, and anything turned up goes straight to a supervisor or to the school. Those first two items are why the check takes this shape: a general commercial post-trip has no passengers who might stay behind and no school-bus-only warning gear that might have failed, and either oversight becomes tomorrow morning's emergency. The wrong options all narrow the check to something a truck driver would recognize. Cutting it down to brakes, steering, lights, and tires, or to fuel and pressures for the next shift, treats the bus as a machine and forgets the people who were riding in it. Reviewing and signing off the last inspection report is a real obligation under 49 CFR 396.13, but it is owed before driving rather than after, and it already sits inside general vehicle inspection knowledge. 49 CFR 383.123(a)(2)(i) anchors this question because the school-bus-only equipment being checked is very nearly the list that paragraph itself sets out; general post-trip inspection knowledge lives at 49 CFR 383.111(a)(17)(iv), and neither paragraph says what to look for aboard a bus.
