What is Electronic Stability Control (ESC)?

Electronic Stability Control, commonly abbreviated as ESC, is an advanced safety feature found in modern vehicles that is designed to protect drivers from losing control of their vehicles in certain circumstances. It is a computerized technology that assists in minimizing the chances of skidding or sliding during sudden maneuvers or when encountering slippery road conditions.

ESC constantly monitors the movement and stability of the vehicle. It uses sensors to determine if the vehicle is veering off course or if any wheel is losing traction. When ESC detects any deviation from the intended path, it automatically applies brakes to specific wheels and adjusts engine power to help the driver regain control and keep the vehicle on the intended trajectory. This system greatly improves a vehicle’s stability and handling, reducing the risk of accidents and rollovers.

ESC works in conjunction with other safety systems, such as the antilock braking system (ABS) and traction control system (TCS). Together, these systems provide enhanced safety during emergency maneuvers, sharp turns, and adverse weather conditions.

It is important to note that ESC does not replace safe driving practices but rather acts as a supplemental safety feature. Drivers should always practice defensive driving techniques, maintain proper tire pressure, and ensure their vehicle’s anti-lock brakes are in good working condition.

ESC has become mandatory in many countries due to its effectiveness in preventing accidents and improving vehicle safety. It has been proven to reduce the risk of single-vehicle crashes by up to 49% and multiple-vehicle crashes by up to 20%.
