Which type of unstable load requires extra caution on curves?

• A. Hanging meat or livestock
• B. Boxes of grain
• C. Furniture
• D. Empty pallets

Answer: (A)

Unstable loads change how a vehicle handles on curves because they can move or swing as the truck leans and experiences lateral forces. When you go through a curve, the centrifugal force pushes the load outward. If the load can move, it will shift toward the outside of the turn, altering the trailer’s center of gravity and increasing the risk of loss of control or rollover. Hanging meat or livestock are suspended and free to swing inside the trailer, so their motion can dramatically amplify this effect—making careful speed management and securement essential on curves. Other loads like boxes of grain, furniture, or empty pallets are more fixed or tightly secured and don’t have the same degree of free movement, so while still requiring proper securing, they don’t present the same curve instability risk as suspended loads.
