    Which vehicles should use the left-hand lane on a three-lane motorway?

    DVSA-style practice question · Motorway Rules

    The answer options

    • Emergency service vehicles
    • Slow vehicles
    • Large vehicles
    • Any vehicle not overtakingCorrect

    Why that is the answer

    The Highway Code states that you should always drive in the left-hand lane on a motorway unless you are overtaking. Middle and right-hand lanes are for overtaking only. Once you have passed a slower vehicle, you must move back to the left lane when it is safe. The left lane is for all traffic, not just slow or large vehicles, whenever the road ahead is clear.

    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.
