The answer options
- Leave the interior light on
- Leave the headlights on
- Fit reflective windows
- Etch the registration number into the windowsCorrect
Why that is the answer
Etching the vehicle registration number onto the windows makes your car much harder for thieves to re-identify and sell on. Replacing all the glass is expensive and risky for criminals, making the vehicle a less attractive target. Leaving interior or exterior lights on will not deter thieves and will only drain your battery, while reflective windows do not provide any actual security benefit.
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.
