The answer options
- Poor steering
- Remaining in high gears for longer
- Accelerating round bends
- Harsh braking and acceleratingCorrect
Why that is the answer
Harsh acceleration uses a significant amount of extra fuel because it forces the engine to work much harder. Rapid braking then wastes the energy created, requiring you to accelerate again and burn even more fuel. Driving smoothly and planning ahead reduces unnecessary speed changes. Remaining in higher gears actually improves fuel efficiency by keeping engine revs low. DVSA eco-driving guidance highlights that smooth driving saves fuel and reduces vehicle emissions.
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.
