What is the simplest and most accurate method for reversing a large truck into a garage?

[DeAmelia]

First, at the starting point, when you see about two finger-widths below the rearview mirror, begin to turn the steering wheel fully. Observe the rear end position of the right front door handle; generally, you should correct by turning the wheel back half a turn. Then, for left-side garage reversing, gently lift the clutch to move the vehicle backward, look at the left rearview mirror, and when you reach the position, turn the steering wheel fully to the left. Continue moving backward without stopping, while observing the left rearview mirror to maintain the distance between the vehicle body and the garage corner. When the garage boundary line in the left rearview mirror is parallel to the vehicle body, straighten the steering wheel, adjust the vehicle body, and complete the reversing into the garage.
