The answer options
- It is powered by gravity
- It is powered by electricityCorrect
- It is powered by diesel
- It is powered by diesel
Why that is the answer
Electric vehicles are powered by electricity stored in rechargeable batteries rather than fossil fuels. Because they produce zero tailpipe emissions while being driven, they do not release harmful exhaust gases like carbon dioxide or particulates into the atmosphere. Vehicles powered by diesel burn fossil fuels, which contribute to air pollution and climate change. DVSA guidance highlights choosing electric power as an effective way to reduce your environmental impact.
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.
