What does this mean? DVSA-style practice question · Motorway Rules ## The answer options - The police are ahead - The driver wants you to overtake - They are about to change lanes - Traffic ahead is suddenly slowing or stopping**Correct** ## Why that is the answer Drivers may briefly use their hazard warning lights on a motorway or dual carriageway to warn trailing traffic that queueing or slow-moving traffic is immediately ahead. The Highway Code permits this specific use to help prevent collisions when speed drops abruptly. Hazard lights must never be used to signal a lane change, invite another driver to overtake, or warn others about police presence. ## How this comes up in the real test Questions from motorway rules 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.
