What is a common reason for commercial vehicles to roll over?

Excessive speed during a turn is a primary reason for commercial vehicles to roll over. Large vehicles, such as trucks and buses, have a high center of gravity due to their size and load. When a commercial vehicle takes a turn too quickly, the centrifugal force can increase the risk of tipping over, especially if the vehicle is carrying a heavy load that shifts. This phenomenon is compounded when the vehicle has a higher center of gravity, making it more susceptible to instability in turns.

Maintaining appropriate speeds while turning is crucial for safety. Drivers are trained to understand the dynamics of their vehicles and to adjust their speed according to road conditions and vehicle load. By adhering to speed limits and exercising caution around turns, drivers can significantly reduce the risk of rollover incidents.
