CDL · Doubles and triples

On a set of doubles, where should the rear trailer's landing gear be while you test the coupling?

Correct answer: Raised only a little.

Answer options

  1. ALowered completely.
  2. BRaised only a little. Correct
  3. CRaised completely.

Why

After the converter dolly is backed under the rear trailer, crank that trailer's landing gear up just enough to clear the ground, so the gear will not be damaged if the trailer moves during the tug test. You raise it all the way only after the coupling has been checked and the lines are connected.
