The centre of gravity of an object is the point around which all of its weight is balanced. If the centre of gravity falls outside the object’s base, the object may tip over. Most vehicles are built low enough to the ground so they balance well on hills, curves and uneven road surfaces. But some SUVs, pickup trucks and camper vans have a higher centre of gravity. A vehicle with a higher centre of gravity is less stable on uneven road surfaces and is more likely to roll over on a curve taken at higher speeds. Bear this in mind when driving one of these vehicles.
