An interstate bus has a steering defect listed on its required inspection report that is likely to affect safe operation. Dispatch wants it used before repair. What is required?
Correct answer: Repair the safety-affecting defect before operating the bus.
A carrier must have a listed defect likely to affect safe operation repaired before using the vehicle again. A signature, lighter load or lower speed does not correct that defect.

Before taking over a bus with a required defect report, what does the incoming driver's signature acknowledge?
Correct answer: Review of the report and certification that required repairs were performed.
The signature records the driver's review and the existence of repair certification. It is not a waiver of defects or a promise to perform repairs personally.

Under the current federal inspection-report rule, no defect was discovered by or reported to a bus driver. Does that rule itself require a no-defect written report?
Correct answer: No; the federal rule does not require one in that situation.
The current rule does not require a report when no defect or deficiency is discovered or reported. That does not remove inspection duties or any separate employer or applicable local requirement.

A bus driver is told about a safety-affecting equipment defect during the shift but did not personally discover it. How should a required daily report treat it?
Correct answer: Include the reported defect and identify the affected bus.
Report content includes safety-affecting or breakdown-related defects discovered by or reported to the driver. Identifying the correct vehicle is essential.

The previous bus inspection report has the required repair certification. What must the new driver still establish before driving?
Correct answer: That the bus is currently in safe operating condition.
Reviewing a report does not replace the driver's duty to be satisfied that the vehicle is safe to operate now.

Your bus was parked unattended between assignments. What should you do before accepting passengers?
Correct answer: Inspect the interior for damage and unsafe conditions.

A passenger suggests leaving an emergency exit door open to cool the bus while it moves. What should you do?
Correct answer: Close the emergency exit door before driving.
The handbook directs drivers not to drive with an open emergency exit door or window. A passenger guarding it does not make it a safe ventilation method.

After baggage loading and restroom service, what should the driver check before pulling away?
Correct answer: That the baggage and other exterior access panels are closed.

A bus has a roof hatch designed to lock partly open for ventilation, and its use is permitted. What extra clearance issue must the driver consider?
Correct answer: The open hatch increases the bus's required overhead clearance.
A raised hatch increases height. Follow the vehicle's instructions, account for that clearance and do not treat open hatches as a routine practice.

A standing passenger moves forward of the bus's standee line before departure. What must happen before the driver proceeds?

A bus designed for standing riders uses a painted floor line, not another permitted indicator, to mark the prohibited front area. What is the minimum line width?
Correct answer: 2 inches, in a contrasting color.
The federal marking rule specifies a contrasting line at least 2 inches wide, or another means indicating the prohibited area. This concerns the driver's level, subject to the rule's exceptions.

A permanent passenger seat is ahead of the standee boundary but is positioned so its seated occupant cannot interfere with safe bus operation. Does the standee rule itself prohibit that seat?
Correct answer: No; the rule distinguishes qualifying permanent seats from standees.
The rule does not prohibit permanent seats in that area when seated occupants will not interfere with safe operation. This is not permission for standing passengers or unsecured chairs.

A bus has an aisle seat. Under the federal equipment rule, what must that seat do when unoccupied?

A passenger seat is not securely fastened to the bus. Can the driver operate the bus by putting a sign on that seat?
Correct answer: No; the bus must not operate with an unsecured seat.
A warning does not secure a loose seat. The rule prohibits bus operation when any seat is not securely fastened.

The main bus aisle is clear, but luggage blocks access to an emergency exit window. Is the loading acceptable?
Correct answer: No; every occupant must have unobstructed access to all exits.
Keeping the main aisle clear is not enough. Stowed articles must not obstruct occupants' access to any exit.

A case beside the bus driver's seat limits arm movement during steering. What should happen before departure?
Correct answer: Restow it so the driver can move and operate the bus freely.
Baggage must be positioned as well as secured so it does not restrict driver movement or proper operation. Tightening an obstruction in place does not solve the problem.

An overhead item could fall onto riders during a sudden stop even though it does not block an exit. What is needed?
Correct answer: Stow and secure it to protect occupants from falling or shifting.
Bus loading must also protect occupants from falling or displaced articles. Clear exits alone do not make an unsecured overhead load safe.
