When reversing a semi-trailer, which steering action is correct?

• A. Turn the steering wheel in the opposite direction of where you want to go
• B. Turn the steering wheel in the same direction you want to go
• C. Honk and then reverse
• D. Keep steering wheel straight

Answer: (A)

When backing a semi-trailer, the steering wheel only controls the tractor’s front wheels, while the trailer pivots on the hitch. This creates a opposite-reacting effect: the trailer will swing in the direction opposite to how you steer the tractor. So to place the trailer where you want it, you steer in the opposite direction of the target path and make small, calm corrections as you go. Steering in the same direction as the desired movement tends to push the trailer away from the plan and can lead to jackknifing or loss of control. Honking or trying to reverse with the wheel straight won’t guide the trailer onto the correct path, and keeping the wheel straight eliminates the necessary adjustment.
