Backing under your trailer at an angle can cause which of the following?

• A. Push the trailer sideways.
• B. Keep the air lines from getting pinched.
• C. Damage/break the landing gear.
• D. Both A and C.

Answer: (D)

Backing a trailer at an angle creates sideways forces that the trailer isn’t designed to handle when coupling. The kingpin and trailer frame aren’t aligned with the tractor’s path, so as you back, the trailer tends to drift sideways. That sideways push can stress the landing gear and even bend or damage the legs, especially if the trailer is heavy or not fully supported. The air lines between the tractor and trailer aren’t a guaranteed protection against this misalignment; backing at an angle can increase the chance of pinching or kinking those lines as the connections flex. So the real risks are the trailer being pushed sideways and potential damage to the landing gear.
