    If your anti-lock brakes (ABS) warning light stays on, what should you do?

    DVSA-style practice question · Safety and your Vehicle

    The answer options

    • Ensure the parking brake is released
    • Check the level of brake-fluid
    • Check the footbrake free play
    • Immediately have the brakes checkedCorrect

    Why the other options are wrong

    • “Ensure the parking brake is released” is a distractor. It does not meet the standard the question is testing, which immediately have the brakes checked does. Picking it in the real test costs a mark you cannot get back, and with a pass mark of 43 out of 50 you only have seven to spare.

    Why that is the answer

    An illuminated ABS warning light indicates a fault within your anti-lock braking system. While your conventional brakes should still function, the ABS will not work during an emergency stop, increasing the risk of skidding. Official DVSA guidance advises having the system checked by a qualified mechanic immediately. Simply checking the brake fluid level or parking brake will not resolve an electronic ABS fault, so prompt professional repairs are essential.

    What safety and your vehicle covers

    • · Legal minimum tread depth of 1.6mm across the central three-quarters
    • · Dashboard warning lamp colours and which mean stop immediately
    • · Braking, steering and suspension faults and how they feel
    • · Fuel economy, emissions and eco-safe driving technique

    Mistakes learners repeat on this topic

    • · Quoting 1.6mm as an all-weather safe depth rather than the legal minimum
    • · Checking tyre pressures when the tyres are hot instead of cold
    • · Treating an amber warning lamp as something to ignore
    • · Forgetting that an over-inflated tyre wears in the centre, not the edges

    Instructor tip: Learn the warning lamp colours as a traffic-light system: red stop, amber investigate, green or blue informational.

    How this comes up in the real test

    Questions from safety and your vehicle 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.

    Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
