What is the most probable cause of rollovers?

Speed is identified as the most probable cause of rollovers because excessive speed can lead to a loss of vehicle control, increasing the likelihood of tipping over, especially during sharp turns or evasive maneuvers. When a vehicle is traveling too fast, centrifugal force can overpower the vehicle's stability, particularly in high center-of-gravity vehicles, which are more susceptible to rollovers. Keeping speed within safe limits helps ensure better control and stability, reducing the risk of rollovers.

Other factors, such as weather conditions, can contribute to overall driving challenges, but speed has a more direct impact on the dynamic forces acting on the vehicle during maneuvers. Driver distraction also plays a role in overall driver safety but is not a primary cause of rollovers. Vehicle weight can affect stability and braking but is typically less influential than the speed at which a vehicle is being operated.
