There are multiple reasons a vehicle may roll over, including: Tripping: Tripping is one of the most common reasons vehicles roll over. It occurs when a car's tire hits something — such as a curb or ditch — that shifts the vehicle's weight to one side, causing it to roll before it can regain its balance. Speeding: If you speed around a curve or take a turn too fast, the tires can lose their grip on the road, leading to a vehicle rollover. Crashing: If you're in an accident and the force from the other vehicle is strong enough, it can tip your car. Inclement weather: When the roads are covered in rain, snow, or ice, roads become slippery, making it easier to lose control of your vehicle, skid off the road, and roll your car.
