What should a driver do when reversing a semi-trailer?

• A. Turn the steering wheel in the same direction as the trailer
• B. Turn the steering wheel in the opposite direction to where you want the trailer to go
• C. Keep the steering wheel straight
• D. Back up without steering to stay in a straight line

Answer: (B)

When reversing a semi-trailer, the driver must turn the steering wheel in the opposite direction to where they want the trailer to go. This is due to the way articulation points between the tractor and trailer function. When a driver turns the steering wheel, the front of the tractor moves in the direction of the turn, which causes the rear of the tractor to move in the opposite direction. Therefore, if the driver wants the trailer to move to the right, they need to turn the steering wheel to the left, effectively directing the front of the tractor left and allowing the trailer to follow behind and swing to the right. Understanding this principle is crucial for safely maneuvering large vehicles, especially in tight spaces. It helps in avoiding obstacles and maintaining control over the trailer’s movement, which can be significantly different from standard passenger vehicles due to their size and the mechanism of articulation. It can be a common misconception for inexperienced drivers to believe the turns are made in the same direction, but mastering this skill is essential for effective and safe backing maneuvers.
