During the uncoupling pull-away pause, what are you checking?
- A.That the engine temperature is normal
- B.That the landing gear is holding, the trailer is not sinking, tilting, or rolling, and nothing is still connected
- C.That the radio still works
- D.That the trailer doors are locked only
Correct answer
B. That the landing gear is holding, the trailer is not sinking, tilting, or rolling, and nothing is still connected
Why
This is the last chance to catch a sinking leg, a forgotten air line, or a trailer starting to tip while the tractor can still support it. A few seconds here prevents a dropped trailer.
