Which factor is crucial in preventing vehicle rollovers?

Proper loading and weight distribution is critical in preventing vehicle rollovers because it directly affects a vehicle's center of gravity and overall stability. When a vehicle is loaded unevenly or exceeds recommended weight limits, it can shift its center of gravity higher, making it more prone to tipping over, especially during sharp turns or sudden maneuvers. For instance, if the cargo shifts or if an excessive amount of weight is placed on one side of the vehicle, it can create an imbalance that increases the risk of a rollover.

Maintaining a low and evenly distributed center of gravity helps ensure that the vehicle remains stable during operation. This is particularly important for large vehicles, such as trucks and buses, which have a higher risk for rollovers due to their size and load capacity. Proper loading techniques and adherence to weight limits not only enhance safety but also comply with regulations designed to keep both drivers and others on the road safe from accidents.
