What is the effect of bad weight distribution on a truck?

Bad weight distribution on a truck can lead to decreased handling and longer stopping distances, making option B the correct choice. When a truck's weight is not evenly distributed, it can cause instability and affect the vehicle's grip on the road. This instability makes it harder to maneuver and control the truck, especially in emergency situations or when turning.

Moreover, an uneven weight distribution can impact the braking system. If the load is too heavy on one side, that side may not stop as quickly as the other, leading to longer stopping distances. This is particularly hazardous in heavy vehicles where breaking distance is already amplified due to their mass. Good weight distribution is essential for safe operation, as it ensures that each tire carries an appropriate amount of weight, enhancing overall handling and braking effectiveness.

The other options do not accurately reflect the consequences of poor weight distribution. It does not improve fuel efficiency or tire performance; in fact, it can cause uneven tire wear and potentially lead to tire blowouts. The assertion that bad weight distribution has no effect is also misleading, as it has serious implications for safety and vehicle performance.
