Correct answer

  1. A Nothing additional
  2. B The stop arm, alternating flashing warning lights (amber and red), crossview/convex mirrors, the service door, emergency exits, and any wheelchair lift/securement equipment — items specific to student safety
  3. C Only the tires
  4. D Only the engine

Why this is the answer

SCHOOL BUS-SPECIFIC INSPECTION ITEMS (beyond standard CMV and passenger bus checks):

Stop arm: Extends and retracts properly, undamaged.

Warning lights: Alternating amber and red flashing lights all work.

Crossview/convex mirrors: The special mirrors (front fender convex mirrors and crossover mirrors) that let the driver see the danger zone in front of and beside the bus — properly adjusted and clean.

Service door: Opens/closes properly.

Emergency exits: All function, open, and warning buzzers work; WHEELCHAIR LIFT and SECUREMENT equipment (if equipped): Functional.

Seating: Secure.

Floors/aisles: Clear; FIRE EXTINGUISHER, FIRST AID KIT, EMERGENCY EQUIPMENT: Present and accessible; these items are critical to student safety; the warning light/stop arm system protects loading/unloading; the crossview mirrors let the driver see children in the danger zone; emergency exits enable evacuation; the school bus pre-trip includes all standard inspection items PLUS these student-safety-specific components; verifying them every trip is essential because they directly protect children — a non-functioning stop arm, warning light, or crossview mirror endangers students.
