Where should you position an empty ISO container on the trailer during part-loading?

• A. Over the rear axles
• B. Close to the fifth wheel
• C. Close to the trailer edge
• D. Over the front axle

Answer: (A)

Center of gravity and axle weight distribution are what this is testing. When you’re part-loading, you want a starting position that gives you the most flexibility to balance the trailer as you add other loads, while keeping axle weights within limits and maintaining stable handling. Putting an empty ISO container over the rear axles places the load toward the back of the trailer, which gives you room to move heavier cargo forward later to bring the overall balance toward the middle. It helps keep the front (steering) axle from being overburdened as you add more weight, and it improves stability during braking and cornering because you’re not loading the front axle heavily from the outset. If you started with the container near the front end or near the edge, you’d restrict your ability to adjust the balance safely as loading continues, increasing the risk of excessive load on the front axle or loss of stability.
