# How should you avoid fuel spillage?

DVSA-style practice question · Attitude

## The answer options

-   Ensure the filler cap is securely fastened**Correct** 
-   Ensure the tank is only 3/4 full 
-   Ensure you've used a locking filler cap 
-   Ensure the fuel gauge is working 

## Why that is the answer

Always make sure your fuel filler cap is securely fastened after refuelling. A loose cap allows fuel to spill onto the road, particularly when turning or accelerating. The Highway Code warns that diesel spillage creates a dangerously slippery surface, placing other road users, especially motorcyclists, at great risk. You do not need to restrict filling to three-quarters full, provided you do not overfill the tank and the cap is properly secured.

## 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.

## Passed your theory? Get the practical booked

Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
