Which procedure is not recommended when backing a tractor/trailer combination?

Turning toward the passenger's side while backing a tractor/trailer combination is not recommended due to the increased risk of losing sight of the trailer's path and potential hazards that may be present on that side. It can create a situation where the driver has a limited view and may not fully appreciate the positioning and direction of the trailer.

In contrast, turning toward the driver’s side is generally recommended because it allows the driver to maintain a better line of sight and visibility of the trailer. Additionally, using mirrors for guidance is crucial as they provide a view of the surrounding area and help monitor the trailer's movement. Checking blind spots regularly is equally important as it ensures that the driver is aware of any obstacles or pedestrians that may not be visible through the mirrors. These practices help maintain safety when maneuvering large vehicles.
