DVSA-style practice question · Alertness ## The answer options - To avoid the wind - To be able to corner quicker - To allow the large vehicle to stop easier - To allow the driver to see you in their mirrors**Correct** ## Why that is the answer Large vehicles have significant blind spots, especially directly behind them. Staying a good distance back ensures you remain visible in the driver's side mirrors. It also dramatically improves your own view of the road ahead, giving you more time to react to hazards. Dropping back does not help the large vehicle stop or let you corner faster, but it keeps you safe. ## How this comes up in the real test Questions from alertness 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.
