A bus's passenger doors are closed, but an exterior baggage-service panel remains open after work at the terminal. What must happen before departure?
Correct answer: Close and secure the access panel as intended.
The outside inspection includes closing access panels for baggage, engine and other service areas. Passenger-door closure does not establish that exterior service panels are safe for travel.

A bus was left unattended during a layover. Its interior passed inspection earlier that day. What is the correct approach before carrying the next group?
Correct answer: Check the interior again for damage and unsafe conditions.
An unattended bus can be damaged. The driver must verify that the interior remains safe, including passenger areas and emergency equipment; an earlier check is not proof of its present condition.

A handrail beside a bus's boarding steps moves in its mounting when checked. The steps themselves are clear. How should the handrail be treated?
Correct answer: As a passenger-safety defect that must be corrected.
Each handhold and railing must be in safe condition. A clear stairwell or gentle driving does not make an insecure support safe for boarding and exiting passengers.

A bus aisle contains no bags, but a loose edge of floor covering curls upward where riders walk. Which conclusion is sound?
Correct answer: The floor covering is still a trip hazard requiring attention.
The interior check includes the floor covering itself, not merely objects left on it. A lifted edge can trip passengers entering, leaving or moving through the bus.

A notice taped inside a bus covers the emergency-door identification sign. The handle and door appear to work. What should be done?
Correct answer: Remove the obstruction so the emergency-exit sign is clearly visible.
Emergency-door identification must remain clearly visible. A functioning handle or a spoken reminder does not replace permanent visible identification for everyone who may need the exit.

A passenger seat's cushion is intact, but the seat frame shifts because a mounting is loose. What does the driver need to recognize?
Correct answer: The seat is not safe merely because its cushion looks good.
All seats must be securely fastened to the bus. Cosmetic condition is not a substitute for sound attachments, and leaving one seat empty does not repair the mounting.

A coach is equipped with a restroom emergency buzzer. During the parked check it fails, although the ordinary stop-request buttons work. Which assessment is correct?
Correct answer: The fitted emergency buzzer needs attention; other signal buttons do not replace it.
If the bus has the equipment, its restroom emergency signaling device is part of the interior safety check. This does not claim every bus has a restroom or uses the same signaling arrangement.

A bus design permits a roof hatch to be secured partly open for ventilation, and its actual instructions allow that use. What additional driving consideration follows from that position?
Correct answer: The partly open hatch increases the bus's overhead clearance requirement.
Some roof hatches have a permitted partly open position, which increases height. Account for the actual open-hatch clearance; this is not permission for routine open-hatch travel on every model or for open emergency doors and windows.

On an interstate passenger bus subject to the federal bus-operation rule, a bag is secured near the driver. It does not block an exit, but it interferes with the driver's movement needed to operate the bus. Is that stowage acceptable?
Correct answer: No; baggage must also allow the driver to move and operate the bus freely.
Safe stowage must preserve the driver's freedom of movement and proper operation, as well as exit access and protection against shifting articles. Satisfying just one of those requirements is not enough.

On an interstate passenger bus subject to the federal bus-operation rule, a securely strapped case blocks access to an emergency window. The normal entry door and aisle remain clear. What must change?
Correct answer: The case must be stowed so that the emergency window remains accessible.
Securing an article against movement does not excuse blocking an exit. The bus-operation rule protects access to all exits by any occupant, not only the normal boarding door.
