Why that is the answer
Red reflective studs mark the left-hand edge of the carriageway, separating the main road from the hard shoulder or verge. They help you identify the boundary of the road in the dark or in bad weather. Do not confuse these with green studs, which show where slip roads join or leave, or white studs, which separate lanes. Amber studs mark the right-hand edge next to the central reservation, as outlined in the Highway Code.
How this comes up in the real test
Questions from vehicle handling 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.
