During the pre-trip inspection of a bus, what must the driver check regarding the passenger seats?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Seat mounting — are seats firmly attached with no wobble or broken frames; seat back integrity — seats that collapse forward on braking can injure passengers; condition of any seatbelts on equipped buses; aisle must be clear for emergency evacuation

  1. A Seats require no inspection
  2. B Seat mounting — are seats firmly attached with no wobble or broken frames; seat back integrity — seats that collapse forward on braking can injure passengers; condition of any seatbelts on equipped buses; aisle must be clear for emergency evacuation
  3. C Only that the seats are clean
  4. D Only count the number of seats

Why this is the answer

PASSENGER SAFETY requires that every seat be structurally sound. A loose or broken seat that shifts during a crash or emergency stop can cause serious passenger injury — the seat becomes a projectile and the passenger loses their restraint system. Pre-trip seat inspection: manually push on each seat to check mounting stability; test seat backs for collapse resistance; verify any seat belts (required on over-the-road coaches manufactured after 2016) are functional and undamaged; ensure the aisle remains clear of obstructed egress paths.
