How can you avoid wasting fuel?
- A By having your vehicle serviced regularly
- B By revving the engine in the lower gears
- C By keeping an empty roof rack on your vehicle
- D By driving at higher speeds where possible
Why this is the answer
If you do not have your vehicle serviced regularly, the engine will gradually become less efficient. This will cause increased fuel consumption and, in turn, an increase in the amount of harmful emissions it produces.
Why the other answers don't fit
- B
- By revving the engine in the lower gears — High revs in a low gear is one of the quickest ways to waste fuel.
- C
- By keeping an empty roof rack on your vehicle — An empty rack is pure drag with nothing to show for it.
- D
- By driving at higher speeds where possible — Fuel use climbs sharply with speed.

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.
