What should you do? DVSA-style practice question · Incidents, accidents and emergencies ## The answer options - Deal with it when you have time to do so - Continue, the engine sounds fine - Hope it is a temporary fault - Investigate the problem promptly when safe to do so**Correct** ## Why that is the answer Warning lights alert you to potential safety or mechanical faults. Ignoring them can cause severe vehicle damage or lead to a dangerous breakdown. Even if the engine sounds fine, serious underlying issues like brake or oil faults might not make an immediate noise. You should find a safe place to stop promptly, consult your vehicle handbook, and investigate the problem before continuing your journey. ## How this comes up in the real test Questions from incidents, accidents and emergencies 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.
