Basic Controls (Maneuvers) for the CDL Exam

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

• !Too many pull-ups — most states allow 2 free, then deduct
• !Crossing boundary lines (encroachments) — counted regardless of correction
• !Using the side mirror instead of "GOAL" (Get Out And Look) when uncertain
• !Failing to set up the maneuver from the right starting position

Study tips

• 1Practice "GOAL" early — examiners do not penalise getting out to look; they penalise hitting cones.
• 2Drill the off-set alley dock approach: align tractor parallel to the lane, count tractor lengths, sweep into the dock.
• 3Memorize state-specific encroachment and pull-up limits before test day.
• 4Set up consistent reference points (mirror corner aligned with cone, etc.) — reproducible setup is what passes.

1. 1

   During the off-set alley dock maneuver, the most common failure is:

   • AStalling the engine
   • BExcessive pull-upsCorrect
   • CStopping too quickly
   • DLooking in the wrong mirror
   Why this answer?

   Too many pull-ups is the most common cause of failure on the alley dock. Examiners typically allow 2 free pull-ups before deducting points; setting up correctly the first time avoids the issue.
