The answer options
- Fuel consumption can improve
- Exhaust emissions can increase
- The engine may struggle to start
- The road can be made slippery for other usersCorrect
Why that is the answer
A loose or missing fuel cap allows diesel to spill onto the road, particularly when turning, accelerating, or braking. Diesel is oily and does not evaporate quickly, making the carriageway extremely slippery and dangerous for other road users, especially motorcyclists and cyclists. Always ensure your fuel cap is securely fastened after refuelling. While spilling fuel increases fuel consumption, the primary safety concern is the hazard created on the road surface.
How this comes up in the real test
Questions from attitude 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.
