Why should you back toward the driver's side?

Backing toward the driver's side is emphasized primarily because it allows for better visibility. When the driver backs toward the driver's side, they are more likely to see pedestrians, obstacles, and other vehicles, as their view is largely unobstructed. This is crucial for ensuring safety when maneuvering a large vehicle, as blind spots can make it difficult to see anything on the passenger side. Enhanced visibility while backing helps in making better judgments about the space and surroundings, ultimately reducing the likelihood of accidents.

The other options, while reflecting some aspects of vehicle operation, do not capture the primary reason associated with the question as accurately as the visibility factor does. While convenience and damage prevention may have some relevance in specific situations, they are secondary to the critical need for safety through better visibility. Legal requirements about backing procedures may also exist, but they vary by jurisdiction and don't specifically relate to the benefits of backing towards the driver's side in terms of visibility.
