Why should the load be evenly distributed across the vehicle?

The load should be evenly distributed across the vehicle primarily to prevent excessive wear on tires and enhance stability. An unbalanced load can lead to uneven tire wear, which not only reduces the lifespan of the tires but can also compromise safety by increasing the likelihood of a tire blowout. Additionally, a well-distributed load is crucial for maintaining the vehicle's center of gravity, which directly influences how it handles during turns and stops. This stability is essential for safe operation, especially in larger vehicles, as it helps prevent jackknifing and rollovers.

While organizational aspects, faster loading/unloading times, and visibility can be considerations in vehicle operation, they are secondary to the primary safety and functionality concerns related to load distribution. Properly distributing the load ensures that the vehicle handles predictably, which is vital for the driver's control and overall road safety.
