  1. Q1. You are loading a trailer. How should the load be distributed?

    1. A. Equally between all four corners
    2. B. Heavier items at the rear to give stability
    3. C. Most of the weight over or slightly in front of the trailer axle, and the nose weight within the vehicle manufacturer's limits Correct answer
    4. D. Load as high as possible for stability

    Explanation. Weight should be placed mainly over or just in front of the trailer axle, with the nose weight (download on the tow ball) within the tow vehicle's specification. Too little nose weight causes trailer snaking.

  2. Q2. What is the effect of overloading a vehicle?

    1. A. Better fuel economy
    2. B. No effect if the load is secured
    3. C. It affects braking, stability, steering and can damage tyres and suspension Correct answer
    4. D. Only affects performance above 60 mph

    Explanation. An overloaded vehicle is dangerous: braking distances increase, handling deteriorates, tyres can fail, and suspension/steering can be overloaded. It is also illegal.

  3. Q3. You are carrying a heavy load in the boot of your car. What effect might this have?

    1. A. No effect
    2. B. It reduces braking efficiency and the vehicle may steer more lightly at the front (lighter front axle load) Correct answer
    3. C. It improves traction
    4. D. It improves braking by adding weight

    Explanation. A heavy boot load shifts weight rearward, lightening the front axle and reducing steering response. It also increases the total load on the rear tyres and suspension.

  4. Q4. How must a load be carried if it extends beyond the side of the vehicle?

    1. A. It is illegal to carry any load that extends beyond the bodywork
    2. B. It may be carried but must be clearly marked with a red flag or official marker during daylight, and lit at night if over 1 metre Correct answer
    3. C. No marking is required unless the load extends more than 2 metres
    4. D. Only permissible with a police escort

    Explanation. A load projecting sideways must be marked. Projections forward, sideways or rearward beyond certain distances require special permission, markers, or a police escort.

  5. Q5. How must a load be secured when being transported?

    1. A. It must be tied down with any available rope
    2. B. It must be properly secured so it cannot move, shift, or fall from the vehicle Correct answer
    3. C. Only large loads need securing
    4. D. No legal requirement to secure loads inside a vehicle

    Explanation. All loads must be properly secured using appropriate lashings, nets or straps. An unsecured load that falls from a vehicle is dangerous and the driver can be prosecuted.

  6. Q6. When would you need to adjust your tyre pressures for a heavily laden car?

    1. A. Never — tyre pressures are fixed
    2. B. Check the vehicle handbook — many manufacturers specify higher pressures for a fully laden vehicle Correct answer
    3. C. Always reduce tyre pressure when heavily loaded
    4. D. Tyre pressure has no effect on a loaded car

    Explanation. Many vehicle handbooks specify higher tyre pressures for a fully laden vehicle to maintain correct load rating and handling. Always check the handbook.

  7. Q7. What hazard can a roof rack create even when empty?

    1. A. None when empty
    2. B. Reduced visibility from rear view mirror
    3. C. Wind noise, increased fuel consumption, and potentially altered vehicle height — a danger in car parks and under barriers Correct answer
    4. D. Extra weight on the roof

    Explanation. Even an empty roof rack increases aerodynamic drag (reducing fuel efficiency), may increase overall vehicle height (check barriers and low bridges), and can add noise.

  8. Q8. You are about to drive a vehicle towing a caravan or trailer. What must you check?

    1. A. Only that the lights are working
    2. B. The tow hitch is correctly connected, the jockey wheel is raised and locked, breakaway cable is attached, lights are working and board is visible, nose weight is correct and load is evenly distributed Correct answer
    3. C. Only that the mirrors are adjusted
    4. D. Check fuel only

    Explanation. Before towing, check: hitch is secure, jockey wheel raised, breakaway cable attached, lights and number plate visible, mirrors adjusted for wider view, nose weight correct, and load secured.

  9. Q9. Your vehicle has a maximum authorised mass (MAM) displayed. What does this mean?

    1. A. The maximum speed for the vehicle
    2. B. The maximum gross weight the vehicle may legally operate at when fully laden (vehicle + load + fuel + passengers) Correct answer
    3. C. The weight of the vehicle when empty
    4. D. The weight of the engine

    Explanation. The MAM (or GVW) is the maximum legal weight of the vehicle fully loaded. Exceeding it is illegal and dangerous.

  10. Q10. A load projects more than 1 metre to the rear of your vehicle. What must you do?

    1. A. Nothing — rear projections are unrestricted
    2. B. Fit a rear marker and, if over 2 metres at night, a red light or reflector Correct answer
    3. C. Only mark it if it is over 2 metres
    4. D. Obtain a permit from the DVLA

    Explanation. A rear projection of more than 1 metre needs marking with a red flag during daylight. Longer projections require specific markers and lighting at night. Beyond certain lengths a police escort is required.

  11. Q11. Who is responsible for ensuring a load is secure?

    1. A. The driver Correct answer
    2. B. The passenger
