What will happen if the power-assisted steering system fails?
- A The steering mechanism will lock
- B The steering will become hard to turn
- C The steering mechanism will not respond
- D The steering will become very loose
Why this is the answer
Most power steering systems only work when the engine is running. If the power steering system fails (or the engine cuts out), much more effort will be needed to steer the vehicle.
Why the other answers don't fit
- A
- The steering mechanism will lock — The mechanism does not lock; it simply loses its assistance.
- C
- The steering mechanism will not respond — The steering still responds, and it takes far more effort.
- D
- The steering will become very loose — Looseness points to worn linkage, not to lost assistance.

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.
