Which advanced driver assistance system (ADAS) is designed to actively prevent collisions?
- A Automotive night vision
- B Driver drowsiness detection
- C Advanced emergency braking system
- D Cruise control
Why this is the answer
Advanced emergency braking uses sensors on the car to detect objects ahead. The system analyses whether you’re reacting and the collision risk. If it calculates that you’re likely to crash, the system applies the brakes to try to prevent a collision.
Why the other answers don't fit
- A
- Automotive night vision — It helps you see. It does not act for you.
- B
- Driver drowsiness detection — It warns you to rest, which is not the same as preventing a collision in the moment.
- D
- Cruise control — It holds a speed and does nothing about what is ahead.

Where this question comes from
The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
