The answer options
- The system is running a test
- The system has turned off
- The system has a fault
- The system has activatedCorrect
Why that is the answer
Electronic Stability Control detects when your vehicle is losing grip or starting to skid. If the ESC indicator lamp lights up or flashes while you are driving, it means the system has activated to help you maintain control and restore traction. If the light stays on permanently, this would indicate a system fault or that it has been manually turned off, but a brief illumination shows the safety system is actively working.
How this comes up in the real test
Questions from safety and your vehicle appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
