Quizplus · Accepted Answer

Technician A is correct because ESC systems apply the brake at the inside rear wheel to help counteract understeer by creating a yaw moment that helps the vehicle turn more effectively. Technician B is incorrect because ESC does not extend a car's physical limits or increase traction; it helps maintain control within the existing limits.
