The answer options
- Increase journey times by around 15%
- Reduction of fuel use by around 15%Correct
- Increase your fuel use by around 15%
- Reduce journey times by around 15%
Why that is the answer
Driving smoothly by reading the road ahead, accelerating gently, and avoiding unnecessary braking reduces fuel consumption by around 15%. Harsh acceleration and heavy braking waste energy and burn far more fuel. Although some motorists assume driving aggressively reduces journey times, it rarely makes a significant difference to arrival times and actually increases fuel use and wear on your vehicle.

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.
