DVSA-style practice question · Vulnerable Road Users ## The answer options - Sharply brake - Set your mirror to dazzle them back - Set your mirror to anti-dazzle positioning**Correct** - Flash your rear lights ## Why that is the answer If headlights from a vehicle behind dazzle you, set your interior rear-view mirror to the anti-dazzle position. This cuts down glare while still allowing you to monitor traffic behind safely. The Highway Code warns against braking sharply or trying to dazzle the driver back, as aggressive reactions or sudden stops can easily cause a serious collision. Stay calm, adjust your mirror, and focus on the road ahead. ## How this comes up in the real test Questions from vulnerable road users 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.

Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
