Pick an answer to test yourself.
Correct answer
To keep the vehicle steady and prevent skidding.
Official explanation
Electronic Stability Control (ESC) is an active safety system which can be fitted to cars, buses, coaches, and trucks. It is an extension of anti-lock brake technology, which has speed sensors and independent braking for each wheel. It aims to stabilise the vehicle and prevent skidding under all driving conditions and situations within physical limits. It does so by identifying a critical driving situation and applying specific brake pressure on one or more wheels as required. If necessary, the engine torque is also adjusted automatically.
