There are several reasons why a car rolls over during driving: improper speed control is easy to roll over: "No matter what kind of car is affected by improper driving, it may roll over under certain circumstances." Generally speaking, a car with a high center of gravity is more likely to roll over. " According to analysis, most rollover accidents are caused by improper driver operation, such as excessive adjustment of direction when driving at high speed, which leads to the car slipping out and overturning.

Complex road conditions are also a reason, such as bends or sloping sections, which are easy to cause rollover. At the corner, the upper limit of speed limit is clearly marked as 40km per hour, but someone turns at a speed of 60km per hour, which is very likely to lead to a rollover accident. Experts suggest that drivers must slow down when driving on corners or ramps, because high-speed cornering will produce centrifugal force in the opposite direction to the driver's steering wheel, which will cause the car body to tilt. When the centrifugal force is greater than the tire's grip, the vehicle will slip or roll over.

In bad weather, improper driving can also cause the vehicle to roll over, such as rain and snow. Because of water or snow on the road surface, the friction coefficient between vehicle tires and the ground becomes smaller, and the vehicle is prone to roll over due to side slip when braking at high speed. At the same time, maintaining vehicle control is the most important factor to reduce the probability of rollover accidents. Therefore, incorrect tire pressure and excessively worn tires are dangerous. Excessive worn tires may cause the vehicle to slip on the slippery road surface, thus causing the vehicle to slip off the road surface and increasing the risk of rollover. Incorrect tire pressure will accelerate tire wear and may lead to disastrous consequences. It is very important for drivers to properly maintain tires and replace them when necessary.
