Q1When inspecting a bus before a trip, which of the following must you check on every emergency exit door?
Show answer
✓ Correct answer: That it opens easily, closes securely, and is not obstructed
The FMCSA CDL manual requires that emergency exit doors open easily from both inside and outside, close and latch securely, and remain free of obstructions so they are usable in an emergency.
Q2During a pre-trip inspection, you discover that one passenger seat is loose and rocks noticeably when you push it. What should you do?
Show answer
✓ Correct answer: Report the defect and do not drive the bus until the seat is secured or removed from service
The CDL manual states that seats must be securely fastened to the bus; a loose seat is a defect that must be reported and corrected before the vehicle is placed in service.
Q3What is the purpose of the standee line marked on the floor of many transit buses?
Show answer
✓ Correct answer: It marks how far forward standing passengers may stand — they must stay behind it
Federal regulations require that standing passengers on a transit bus remain behind the standee line, which is located behind the driver's seat area to keep the driver's view and controls unobstructed.
Q4Which of the following is a signaling device you must verify is working during a bus pre-trip inspection?
Show answer
✓ Correct answer: Horn
The CDL manual lists the horn as a required signaling device that must be inspected and confirmed operational before every trip.
Q5During pre-trip inspection of a bus, you must check that handrails are:
Show answer
✓ Correct answer: Secure, free of sharp edges, and not missing from any step or aisle location where required
The CDL manual requires handrails to be secure and free of damage such as sharp edges or breaks, as they are essential passenger safety items that must be present and usable at required locations.
Q6Which of the following conditions found during a pre-trip inspection would make a bus UNSAFE to drive?
Show answer
✓ Correct answer: An emergency exit window is cracked and the emergency release handle is missing
A missing or inoperable emergency exit release mechanism is a critical safety defect; the CDL manual states that emergency exits must operate properly, and a bus with a non-functional emergency exit must not be driven until repaired.
