Before backing a tractor under a semitrailer, how should the tractor be positioned?
Correct answer: D – Directly in front of and aligned with the trailer
In the Arkansas CDL coupling sequence, the tractor is positioned directly in front of the trailer and its alignment is checked using both outside mirrors. Backing under at an angle can push the trailer sideways and damage the landing gear. The tractor should then be backed slowly using the lowest reverse gear.
