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.

The previous bus inspection report has the required repair certification. What must the new driver still establish before driving?

Reviewing a report does not replace the driver's duty to be satisfied that the vehicle is safe to operate now.

A passenger suggests leaving an emergency exit door open to cool the bus while it moves. What should you do?
