Home › CDL Practice Tests › Combination Vehicles Questions › Question 125
Which combination of findings confirms a sound coupling from the equipment side?
- A.Handle out, small gap, latch open
- B.Jaws open but trailer resting on the plate
- C.Kingpin touching the throat only
- D.Jaws closed on the kingpin shank, no apron gap, release handle fully in, and safety latch closed
Correct answer
D. Jaws closed on the kingpin shank, no apron gap, release handle fully in, and safety latch closed
Why
No single sign is enough; the set of them together proves the pin is seated, gripped, and locked against release. Checking all four takes seconds and is the driver's final guarantee.
