What should you check before setting off? DVSA-style practice question · Vehicle Handling ## The answer options - Radiator anti-free levels - Your vehicle has a warning triangle - The lights and windows are clear and clean**Correct** - You have a mobile phone ## Why that is the answer Before driving in fog, you must ensure maximum visibility for yourself and other road users. Clean windows help you see as clearly as possible, while clean lights ensure your vehicle is visible to others through the poor weather. While checking radiator anti-freeze is useful winter maintenance, ensuring your lights and windows are clean is essential for immediate safety before setting off in fog, as advised by the Highway Code. ## How this comes up in the real test Questions from vehicle handling 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.
