What should drivers do to prevent rollover accidents when driving heavy vehicles?

To prevent rollover accidents when driving heavy vehicles, it is essential to adopt various safe driving practices, which include all the listed strategies. Driving with an empty load can reduce the risk of tipping over, as a lighter vehicle is generally easier to control. However, it is more critical to focus on maintaining a lower speed and keeping a wider turning radius.

Maintaining a lower speed helps in reducing the center of gravity shift when navigating curves or turns, thus enhancing vehicle stability. Higher speeds can lead to a loss of control and increase the likelihood of a rollover, especially with heavy vehicles that have a higher center of gravity compared to passenger vehicles.

Keeping a wider turning radius is also vital because it allows for smoother turns, reducing the chances of the vehicle leaning excessively, which can initiate a rollover. Sharp turns can shift the vehicle's weight to one side, making it more prone to tipping.

By combining all these strategies—driving with an empty load when necessary, maintaining a lower speed, and keeping a wider turning radius—drivers can significantly reduce the risk of rollover accidents. Therefore, considering all these preventative measures is crucial for ensuring the safety of the vehicle and its occupants on the road.
