After uncoupling and pulling fully clear, what final checks should you make before leaving the trailer?
- A.Only that the tractor is in gear
- B.That the trailer lights stay on
- C.That the trailer is stable and chocked as needed, doors and load are secure, and no lines or equipment are left attached or on the ground
- D.Nothing, uncoupling ends when the jaws open
Correct answer
C. That the trailer is stable and chocked as needed, doors and load are secure, and no lines or equipment are left attached or on the ground
Why
A left trailer is your responsibility until someone else takes it. A final walk-around catches a leaning load, an open door, or a forgotten chock or line before it becomes an incident.
