When backing a tractor with a semi, in which direction should the front wheels be turned?

When backing a tractor with a semi, the correct action is to turn the front wheels away from the direction you want to move. This maneuver is crucial because it helps you align the rear of the trailer with your intended path. When the front wheels are turned away from the desired direction of movement, the rear of the trailer will pivot toward that direction, making it easier to navigate the backing process.

This technique is based on the concept of articulation in vehicle handling; when the front pivots in one direction, the rear follows a different path. If you turn the front wheels in the same direction you want to go, the trailer will move away from the desired path. Thus, understanding and managing this pivoting effect is essential for safe and effective backing of a tractor-semi combination.
