Fifth-wheel coupling components are recommended to be inspected on which schedule?

• A. Weekly
• B. Monthly
• C. Daily
• D. Yearly

Answer: (B)

Regular inspection of the fifth-wheel coupling components helps ensure a safe, secure connection between the tractor and trailer. The recommended schedule for a thorough, hands-on inspection is monthly, because this interval allows time to notice wear or damage on the locking mechanism, jaws, kingpin, mounting bolts, and release handle, and to check that everything moves smoothly and remains secure. Daily pre-trip checks should still be done to catch obvious faults and confirm the coupling is locked before moving, but a detailed inspection is performed monthly to prevent developing faults from going unnoticed.
