Fifth Wheel & Coupling Steps

Just before the fifth wheel contacts the trailer apron, what should you do?

  • A.Stop, get out, and check the alignment and height one more time
  • B.Speed up slightly to finish the connection
  • C.Turn the steering wheel hard to one side
  • D.Release the trailer brakes so the trailer can roll toward you
Correct answer

A. Stop, get out, and check the alignment and height one more time

Why

A final stop and look catches a misalignment or height problem before metal strikes metal. It is far cheaper to correct position now than to repair a bent kingpin or apron.
