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.

On an interstate passenger bus subject to the federal bus-operation rule, a heavy carry-on lies unsecured in an overhead space. It blocks neither the driver nor an exit. What safety issue remains?
Correct answer: It could fall or shift and injure a passenger, so its stowage must be corrected.
Articles must be stowed and secured to protect occupants from falling or displaced baggage. Clear exits and gentle driving do not remove that separate duty.

An ordinary interstate passenger bus subject to the federal bus-operation rule is designed to carry standees. A standing rider on the driver's level steps forward of the marked standee boundary before departure. Where must that rider stand for travel?
Correct answer: Behind the standee boundary.
Standing riders must remain rearward of the standee line or equivalent boundary. This scenario concerns a standee on the driver's level in normal passenger service, not a permanent seated position or driveaway-towaway operation.

A coach's aisle is lower than its seating area. Riders will soon stand to leave at an intermediate stop. When is it best to remind them about that step down?
Correct answer: Before the bus comes to a complete stop, while they can prepare to move carefully.
The manual recommends warning riders about the step down before coming to a complete stop. Give the reminder in a way that does not distract from safely controlling the bus.

A coach is making a scheduled break stop at a busy terminal with several similar buses. Which announcement best supplies the information the manual calls for?
Correct answer: The location, reason for the stop, next departure time and bus number.
At destinations and intermediate stops, give the location, reason for stopping, next departure time and bus number. Those details help riders understand the stop and identify their return service.

A passenger has just boarded a bus that permits standing. The doors are ready to close, but the rider has neither sat down nor obtained a stable brace. What should the driver do before starting?
Correct answer: Wait until the rider is seated or securely braced.
Riders can stumble when a bus starts. Wait for them to sit down or brace themselves before moving; the fact that a bus allows standees does not remove that precaution.

A bus carrying lawful standees approaches a normal stop. No immediate hazard requires abrupt braking. Which stopping style best protects riders?
Correct answer: A smooth, controlled deceleration into the stop.
Starting and stopping smoothly helps prevent passenger falls and injuries. This routine-stop question does not suggest avoiding necessary emergency braking for an immediate danger.

While the bus is moving, a passenger asks the driver to turn around and tell a long story about the route. What is the safer response?
Correct answer: Keep attention on driving and defer the distracting conversation until safely stopped.
Do not engage in distracting conversation or other distracting activity while driving. Necessary passenger supervision does not justify turning away for a prolonged social conversation.

A carrier's procedure calls for ending a disruptive rider's trip. The bus is beside an isolated, unlit shoulder; a staffed, well-lighted stop is nearby. What principle must guide the driver's choice?
Correct answer: Consider the rider's safety too and use a safe discharge location under the carrier's procedure.
Protect the disruptive rider as well as other passengers. Do not discharge a person where it would be unsafe; follow the carrier's procedures and use an appropriate safe location.

A safe traffic gap opens for a bus to leave its stop, but a pole and low branch are close to its outside mirror area. What must the driver still verify?
Correct answer: That the bus and its projecting parts can clear the fixed obstacles.
A traffic gap does not establish physical clearance at the stop. Account for the bus's size and projecting mirrors while checking nearby poles and branches before moving.

A transit coach has the described rear-door interlock: opening the door applies brakes and holds the throttle at idle; closing it releases the interlock. May the driver use that feature instead of the parking brake?
Correct answer: No; use the proper parking brake, not the door interlock as a substitute.
The fitted interlock is a safety feature, not a parking-brake substitute. This question states the particular interlock behavior; it does not assume every coach has the same arrangement.
