A high center of gravity in a vehicle significantly affects its stability during maneuvers, especially while turning. When a vehicle has a high center of gravity, it raises the point where its mass is concentrated, which increases the likelihood of the vehicle tipping over. This happens because, during a turn, the vehicle experiences lateral forces that push it outward. With a higher center of gravity, the balance is less stable, and the risk of rolling over increases as the vehicle leans against these forces. In contrast, vehicles designed with a low center of gravity are generally more stable in turns, making them less prone to rollovers. A high center of gravity can also create challenges in handling and controlling the vehicle during turns, but the primary concern is the increased rollover risk. Therefore, understanding the implications of a high center of gravity is crucial for safe operation, especially for larger commercial vehicles.
