Why should you back towards the driver's side?

Backing towards the driver's side is advantageous because it significantly improves visibility for the driver. When a driver backs towards the driver's side, they are able to see more clearly in their mirrors and have better access to their direct line of sight. This enhanced visibility helps in monitoring the direction of the vehicle, identifying obstacles, and ensuring a safer maneuver overall.

The other reasons, while they may hold some relevance in specific situations, do not capture the primary importance of visibility. Maneuverability can vary based on the vehicle and the specific circumstances of the backing situation, while legal requirements regarding backing often focus more on safe practices than on a specific side. Avoiding obstacles can also be a factor, but it primarily ties back to the broader principle of maintaining heightened awareness and visibility while reversing.
