DVSA-style practice question · Safety and your Vehicle ## The answer options - Leave the interior light on - Leave the headlights on - Fit reflective windows - Etch the registration number into the windows**Correct** ## 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.
