What is the reason for this? DVSA-style practice question · Safety and your Vehicle ## The answer options - You may get held up behind a tractor - Your maps may use different scales - You may have to pay a congestion charge on the original route - Your original route may be blocked**Correct** ## Why that is the answer Unforeseen events like collisions, extreme weather, or emergency roadworks can cause sudden road closures. If your original route is blocked, having an alternative planned allows you to divert safely without getting lost, stressed, or distracted while driving. DVSA guidance stresses the importance of thorough pre-journey planning. While you might encounter slow tractors or congestion charges, only a blocked road completely stops you from continuing on your intended path. ## 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.
