What is the purpose of ensuring there is enough space between the rear of the truck and the landing gear?

The purpose of ensuring there is enough space between the rear of the truck and the landing gear primarily focuses on preventing collisions when the vehicle is turning. Adequate clearance is essential because the rear of the truck can pivot during turns, and without sufficient space, the landing gear could be struck. This could lead to damage not only to the landing gear itself but also to the trailer and associated components.

Maintaining this space contributes to safer maneuvering, particularly in tight spaces or sharp turns, where the risk of impact is heightened. The other options, while relevant in different contexts of truck and trailer operation, do not address the primary function of creating space to prevent impact during turning maneuvers.
