What does it mean if the Electronic Stability Control (ESC) indicator light comes on briefly while you’re driving?
Revision material from the imported DVSA bank includes source-checked Lanekind learning corrections. These corrections are not newly issued official examination questions, and practice does not reproduce a live test paper.

The ESC system has activatedThis was the right answer
ESC is a computer controlled technology that detects reduced traction and automatically makes corrective adjustments to prevent loss of control. The ESC light comes on briefly to alert the driver that the system has activated and the car is approaching its handling limits. It’s a powerful driver aid but it cannot save a car once its traction limits have been exceeded.
