What are two critical factors to prevent a vehicle from rolling over?

Keeping cargo low and centered is crucial for preventing a vehicle from rolling over. This practice ensures that the vehicle’s center of gravity remains stable, which is essential for maintaining balance, particularly during turns or when encountering uneven terrain. When the center of gravity is too high, or when the cargo is unevenly distributed, the risk of tipping increases significantly. By ensuring that cargo is loaded low and in the center of the vehicle, the driver can better manage the dynamics of the vehicle during operation, reducing the likelihood of a rollover incident.

Other options may address various aspects of vehicle safety, but they do not directly influence the center of gravity in the same critical way. For example, reducing speed can help prevent accidents, and parking on flat surfaces is safe for the vehicle when stopped, but they do not alter the fundamental dynamics of weight distribution that affect rollover risk. Having a second driver available might support operational efficiency but doesn't have a direct impact on rollover prevention.
