The answer options
- Through increased fuel bills
- By reducing exhaust emissionsCorrect
- Through the legal enforcement of speed regulations
- By increasing the number of cars on the road
Why that is the answer
Driving in a fuel-efficient manner means your engine burns less fuel. Because less fuel is used, your vehicle produces fewer harmful gases, such as carbon dioxide, directly reducing air pollution and helping to protect the environment. Following official DVSA eco-driving advice, such as accelerating smoothly and anticipating the road ahead, will also help lower your fuel bills rather than increase them.
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.
