A carrier covered by 49 CFR 396.11 is returning a bus to service after a required report listed a safety-affecting defect. What must happen before it is operated again?
Correct answer: Correct the safety defect and complete the required repair certification.
The carrier must repair listed defects likely to affect safe operation and certify on the report that a defect was repaired or repair was unnecessary. A defect that actually affects safety cannot simply be ignored because the previous trip finished. This scenario concerns a required defect report, not a no-defect report.

An otherwise clean passenger seat shifts at its floor mounting during inspection. What is the appropriate response?
Correct answer: Have the insecure mounting corrected before the bus carries passengers.
Passenger seats must be firmly attached. Clean upholstery does not compensate for an unsafe mounting.

A strip of aisle flooring has lifted beside a row of bus seats. Why does this need attention before boarding?
Correct answer: It can make passengers trip while moving through the bus.
The interior check includes walking surfaces and trip hazards. A raised edge can cause a fall even when the bus is not moving.

An emergency-window handle is damaged although the glass is intact. Which conclusion is appropriate?
Correct answer: The exit mechanism needs correction; intact glass alone is not enough.
Emergency exits need working operating mechanisms, not merely undamaged glass. Inspecting handles and access is part of passenger safety.

A decoration hides the sign identifying a bus emergency door. What should be done before departure?
Correct answer: Remove the obstruction so passengers can identify the exit.
Emergency-exit identification must remain visible. Passengers may need to recognize the exit quickly without waiting for the driver's help.

A bus has a roof hatch designed to lock partly open for ventilation. What additional clearance concern does using that position create?
Correct answer: The raised hatch increases the bus's effective height.
A permitted partly open hatch can project above the normal roofline. Account for that extra height; this does not mean every exit may be left open. The handbook advises against leaving a roof hatch open as a regular practice.

After an exterior check, a bus's engine access panel remains unlatched. What should happen before moving?
Correct answer: Close and secure the access panel properly.
Exterior access panels must be secured before movement. An inspection is not complete while covers or panels remain open.

A bus driver is preparing for a short transfer without passengers. How should the driver's seat belt be used?
Correct answer: Fasten and adjust it before driving, including on the short transfer.
The driver's belt helps maintain a proper driving position. A short journey or empty passenger area does not remove the need to use it.

A carry-on bag fits in the aisle without touching a seated passenger. May it remain there for the trip?
Correct answer: No; stow it so the aisle and access to doorways stay clear.
Passenger access and evacuation routes must remain clear. Baggage that seems harmless while everyone is seated can obstruct movement when needed.

A heavy bag is loose on a luggage shelf above occupied seats. What needs to be checked?
Correct answer: That its placement and restraint keep it from falling or shifting onto people.
Baggage must not endanger passengers through movement or falling. Ownership and appearance do not establish safe stowage.

On a bus designed to carry standing passengers, someone stands forward of its marked standee boundary. What should the driver do?
Correct answer: Have the passenger move behind that boundary before proceeding.
The designated boundary keeps standing riders out of the driver's forward working area. A handhold does not make the wrong standing position acceptable.

The aisle is lower than the seating area on a coach approaching a rest stop. Which announcement is useful before passengers get up?
Correct answer: Warn them about the step down into the aisle.
An advance warning about the floor-level change helps passengers avoid falls when leaving their seats. Give useful arrival information before they begin moving.
