Electronic Stability Control (ESC) is a crucial safety feature designed to help prevent rollovers in commercial vehicles. This system works by automatically detecting and reducing loss of traction, which can lead to instability and rollover situations, especially when a vehicle is turning. ESC uses sensors to monitor the vehicle's direction, speed, and steering input, allowing it to apply brakes to individual wheels to help maintain control and prevent skidding or tipping over.

While Anti-lock Braking Systems (ABS) help prevent wheel lockup during hard braking, they do not specifically address the dynamics of a rollover situation. The Tire Pressure Monitoring System (TPMS) focuses on ensuring that tires are properly inflated, which is important for safety and performance but does not directly prevent rollovers. The Traction Control System (TCS) helps manage wheel spin during acceleration, which is beneficial for traction but does not necessarily prevent rollovers during dynamic driving conditions, such as sharp turns or sudden maneuvers. Thus, the ESC is the most effective system for enhancing vehicle stability and preventing rollover incidents.
