Vehicle Maintenance & Inspection Flashcards

Which type of preventive maintenance program schedules service based on actual vehicle mileage, engine hours, or fuel consumption rather than fixed calendar intervals?

Answer: Condition-based maintenance

Condition-based (or usage-based) maintenance triggers service according to actual vehicle usage metrics such as mileage or engine hours rather than set calendar dates.

A fleet safety manager is implementing a systematic program to identify and address mechanical deficiencies before failures occur. This is best described as:

Answer: Preventive maintenance

Preventive maintenance is a proactive approach that schedules inspections and service to detect and correct deficiencies before they cause breakdowns or accidents.

Under FMCSA regulations, who is authorized to perform the required periodic (annual) inspection of a commercial motor vehicle?

Answer: A qualified inspector as defined in 49 CFR Part 396

49 CFR Part 396 defines 'qualified inspector' requirements; inspections must be performed by individuals who meet knowledge and skill criteria specified in the regulation.

What information must be included on a periodic (annual) inspection report for a commercial motor vehicle?

Answer: Vehicle ID, date of inspection, inspector's name and signature, and a list of components inspected

A periodic inspection report must identify the vehicle, state the date of inspection, and include the inspector's name, signature, and address along with the components inspected and their condition.

Which component is specifically required to be checked during a pre-trip inspection of a vehicle equipped with air brakes, per FMCSA guidance?

Answer: Low air pressure warning device functionality

Air-braked vehicles require a check that the low air pressure warning device activates before system pressure drops to a critical level, ensuring the driver will be warned of brake system failure.

A fleet manager notices recurring brake adjustment defects across multiple vehicles. What is the most effective systemic corrective action?

Answer: Increase the frequency of brake-specific preventive maintenance inspections

Recurring defects indicate a systemic gap; increasing the frequency of targeted brake inspections addresses the root cause by catching adjustment issues before they become out-of-service violations.

When must a driver complete a post-trip Driver Vehicle Inspection Report (DVIR)?

Answer: After every trip regardless of whether defects are found

49 CFR 396.11 requires drivers to prepare a DVIR at the completion of each day's work, regardless of whether any defects were found.
