Alabama CDL Class A Permit Practice Test

Keeping cargo balanced in the cargo area is essential because it helps maintain stability during all driving actions—acceleration, braking, and especially turning. When weight is spread evenly from front to back and side to side, the vehicle’s center of gravity stays within a safe range, reducing the risk of swaying, loss of control, or rollover and making steering and stopping more predictable.

Most weight should not be concentrated at the rear or stacked high. Piling weight toward the back shifts the center of gravity rearward and can make the vehicle harder to control, especially at higher speeds or in emergencies. Putting the heaviest items on top raises the center of gravity and increases the chance that the load may shift, upsetting balance. Loading more weight on one side can cause the truck to pull to that side and uneven tire loads, which wears tires unevenly and can affect handling.

So aiming for a balanced, secure load—low, evenly distributed, and well secured—best supports safe, stable driving.
