Question: 1 / 400

What is the impact of a high center of gravity on vehicular accidents?

It has no impact

It can contribute to rolling over on turns

A high center of gravity significantly affects the stability and handling characteristics of a vehicle. When a vehicle has a high center of gravity, it becomes more prone to tipping over during sharp turns, sudden maneuvers, or when encountering uneven terrain. This is particularly true for tall vehicles such as trucks, buses, and vans, which can easily lose balance when their weight shifts during a turn.

During a turn, centrifugal force pushes the vehicle outward, and if the center of gravity is elevated, the risk of the vehicle tipping increases. This is because the weight distribution changes, leading to a higher chance of a rollover. Therefore, understanding the dynamics related to a high center of gravity is crucial for safe driving, especially for commercial drivers who may operate larger vehicles that can be more susceptible to rollover incidents under adverse conditions.
