    Why are these yellow lines painted across the road?

    DVSA-style practice question · Alertness

    Illustration for the theory test question: Why are these yellow lines painted across the road?

    The answer options

    • To tell you the distance until the roundabout
    • To enable you to choose the correct lane
    • To keep the appropriate distance from the car infront
    • To make you aware of the speed you are driving atCorrect

    Why that is the answer

    Yellow bar markings painted across the road encourage drivers to slow down, usually on the approach to a roundabout or hazard. As you drive over them, you can feel and hear the lines, which makes you much more aware of your speed. Do not confuse them with chevron markings, which are used on motorways to help you keep a safe distance from the vehicle ahead. These yellow lines simply prompt you to adjust your speed.

    How this comes up in the real test

    Questions from alertness 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.
