A vehicle with a higher centre of gravity is
- more prone to accelerating quickly.
- more prone to rolling over. ✓
- less prone to rolling over.
- more prone to accelerating slowly.
Answer: B. more prone to rolling over.
A vehicle with a higher centre of gravity is more prone to rolling over.
Why this is the answer
The handbook explains that as the height of a load goes up, the midpoint of the weight, which is the centre of gravity, also moves higher. It states plainly that a vehicle with a higher centre of gravity is more likely to roll over. The same section notes that a loaded vehicle rolls over more easily than an empty one, and that correct loading with cargo kept low and spread out helps prevent rollovers. The passages on livestock and hanging meat say the same thing: a high centre of gravity raises the chance of rolling over.
Why the other answers are wrong
- A. more prone to accelerating quickly. — Nothing in the passages links a high centre of gravity to quick acceleration; the passages talk about rollover risk and load height only.
- C. less prone to rolling over. — This reverses the handbook, which says a higher centre of gravity makes rolling over more likely, not less likely.
- D. more prone to accelerating slowly. — A high centre of gravity is a question of load height and stability, and the passages say nothing about it causing slow acceleration.
Remember it
Think of the load: the taller the weight sits, the tippier the rig, so keep cargo low and close to the deck.
