In a multi-trailer configuration, signs of trailer sway can significantly affect the safety and control of the vehicle. The correct answer highlights important indicators of trailer sway: increased steering response, excessive lateral motion, and difficulty maintaining a straight line.

Increased steering response refers to the driver's need to make more frequent or aggressive steering adjustments to counteract the sway. Excessive lateral motion indicates that the trailers are moving side to side more than usual, which can destabilize the entire rig. Difficulty maintaining a straight line is a direct consequence of the trailers swaying, as the driver will struggle to keep the vehicle on its intended path.

These signs are crucial for a driver to recognize because they can lead to a loss of control, increasing the risk of accidents. Proper training in handling multi-trailer configurations emphasizes the importance of recognizing these signs and addressing them proactively, perhaps by adjusting speed, weight distribution, or even stopping to reassess the load if necessary.
