Vehicle tail swing must be at the forefront of the driver's mind when conducting which of the following maneuvers?

When executing a turn, tail swing becomes a crucial consideration for the driver of a tractor-trailer. As the vehicle approaches a turn, the rear section of the trailer swings outward, potentially encroaching into adjacent lanes or hitting obstacles. This is particularly significant because the length of the vehicle means that the rear does not follow the front in a straight line; instead, it describes a wider arc. This aspect requires careful attention to ensure that the trailer remains within appropriate boundaries and does not pose a hazard to other road users or property. Recognizing and managing tail swing is vital for maintaining safety during turns, making it a priority for drivers to be aware of their vehicle's size and maneuverability under such conditions.
