Think of your steering wheel as a clock, and place a hand at 12 o’clock. Then imagine a line running lengthwise down the middle of your tow vehicle. If your trailer and vehicle are both perfectly straight, or if the rear of the trailer is left of the imaginary center line, the trailer will go left when you turn the steering wheel to the right (clockwise) as you back up. But if the rear of the trailer is right of that imaginary line, the trailer will instead go right when you turn the steering wheel clockwise. Of course, the opposite will happen when you turn the steering wheel to the left (counterclockwise). Keep in mind that the shorter the trailer, the more it responds to minimal steering adjustments.
