DVSA-style practice question · Hazard Awareness ## The answer options - They make traffic look bigger - They give a wider field of vision**Correct** - They cover all blind spots completely - They make it easier to judge traffic speed behind ## Why that is the answer Convex mirrors are curved slightly outwards to give you a wider field of vision than flat mirrors, helping you see more of the road behind and to the sides. However, they make vehicles look smaller and further away than they actually are, which can make judging traffic speed harder. Remember, convex mirrors reduce blind spots but do not eliminate them completely, so you must still carry out checks over your shoulder. ## How this comes up in the real test Questions from hazard awareness 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.
