The height of the vehicle's center of gravity is a critical factor in safe handling, particularly concerning the likelihood of rollover. Vehicles with a higher center of gravity are more prone to tipping over during sharp turns, sudden maneuvers, or when encountering uneven surfaces. This increased risk stems from the way that gravitational forces interact with the vehicle's stability. When the center of gravity is elevated, the vehicle's balance becomes less stable, leading to a higher chance of rollovers, especially in large trucks and buses where the load can significantly affect the center of gravity. Understanding this concept is essential for drivers, as it directly impacts how they should operate their vehicle to maintain safety, particularly during turns and in emergency situations.
