    How can you tell if your vehicle's tyres are losing their grip on a wet road surface?

    DVSA-style practice question · Safety Margins

    The answer options

    • Steering will feel heavier
    • Steering will feel lighterCorrect
    • Engine noise will be increased
    • The car may stall

    Why that is the answer

    When driving on wet roads, water can build up between your tyres and the road surface. This leads to aquaplaning, where the tyres float on a layer of water and lose traction. With no grip, resistance on the wheels drops, causing the steering to feel suddenly light and unresponsive. Heavy steering indicates good friction or a power steering fault. As advised in the Highway Code, ease off the accelerator gradually if this happens.

    How this comes up in the real test

    Questions from safety margins 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.
