Why is it important to use a helper when backing up a vehicle?

Using a helper when backing up a vehicle is important because it significantly helps in avoiding blind spots. When a driver is reversing, they often cannot see directly behind them or may have limited visibility to the sides, which can lead to dangerous accidents or collisions with obstacles, other vehicles, or pedestrians. A helper serves as an extra set of eyes, providing guidance and ensuring that the driver is aware of their surroundings, thereby enhancing safety during the backing maneuver. This practice is especially crucial for larger vehicles, such as trucks, where blind spots can be more extensive and visibility is more limited.

While other factors like distance measurements and encouraging better driving habits are also valuable, the primary goal of having a helper is to enhance visibility and awareness, making the backing process safer for everyone involved.
