Vehicle loading

What this topic tests

Weight, where you put it, and towing. A small topic, and a predictable one: the weight goes over the axles, the driver is responsible, and a trailer that starts to swing is slowed rather than braked.

  • Heavy items over the axles. Too far forward loads the tow ball; too far back lifts it and starts the trailer swinging.
  • A snaking trailer: ease off the accelerator. Do not brake hard, steer sharply or accelerate.
  • The driver is responsible for the load, whoever put it there.
  • A roof load raises the centre of gravity and reduces stability — it is the handling that changes, not the braking.
  • Towing needs a breakaway cable on a braked trailer, and exterior mirrors if the trailer is wider than the car.

The mark people lose: Thinking that a stabiliser fixes bad loading. It damps side winds and buffeting; it cannot correct weight that is in the wrong place.
