Why should you back toward the driver's side when maneuvering a trailer?

When backing a trailer, maneuvering toward the driver's side enhances visibility significantly because it allows the driver to use the driver's side mirror effectively. This positioning offers a clearer line of sight to the back of the trailer, helping the driver to better judge the distance and angle while maneuvering. The driver's side mirror is strategically placed to provide a broader perspective of the area behind the trailer on that side, making it easier to avoid obstacles and safely position the trailer.

In contrast, backing toward the passenger side can create blind spots, limiting the driver's ability to see crucial areas behind and around the trailer. It can also lead to increased difficulty in aligning the trailer properly since the visual reference from the driver's perspective is compromised. Therefore, to enhance safety and accuracy during the backing process, it is recommended to back toward the driver's side whenever possible.
