    What kind of sign tells you what you must not do?

    DVSA-style practice question · Road and Traffic Signs

    The answer options

    • Blue circle
    • Red bordered white circleCorrect
    • Blue square
    • Green square

    Why that is the answer

    Circular signs give orders. A circle with a red border tells you what you must not do, giving a prohibition such as a maximum speed limit or a ban on turning. Blue circles are easily confused with these, but they give positive instructions, telling you what you must do. Rectangular or square signs give information or directions rather than compulsory orders.

    How this comes up in the real test

    Questions from road and traffic signs 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.
