    You are towing a trailer and it begins to swing from side to side. What should you do?

    DVSA-style practice question · Vehicle Loading

    The answer options

    • Accelerate until stabilisation
    • Immediately brake and hold the brake
    • Allow it to correct itself by letting go of the steering wheel
    • Reduce speed by easing off the acceleratorCorrect

    Why the other options are wrong

    • “Accelerate until stabilisation” is a distractor. It does not meet the standard the question is testing, which reduce speed by easing off the accelerator 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

    When a trailer starts to swing from side to side, known as snaking, gently ease off the accelerator to reduce your speed until the combination regains stability. Avoid braking sharply, as this can cause the trailer to jackknife or push the car out of control. Accelerating will only make the instability worse and increase your speed dangerously. Highway Code guidance states you should maintain steady control of the steering wheel while allowing the vehicle to slow down gradually.

    What vehicle loading covers

    • · Driver responsibility for load security and legal weight limits
    • · Loading a trailer or caravan and the effect on stability
    • · Stabilisers, breakaway cables and towing mirrors
    • · Roof racks, roof boxes and the effect on fuel consumption

    Mistakes learners repeat on this topic

    • · Loading heavy items high or towards the rear of a trailer
    • · Assuming a stabiliser corrects a badly distributed load
    • · Believing the passenger is responsible for a child's seat belt
    • · Forgetting that a roof load raises the centre of gravity in crosswinds

    Instructor tip: Any snaking-trailer question resolves to slowing down gently — never brake hard or accelerate out of it.

    How this comes up in the real test

    Questions from vehicle loading 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.
