What causes cars to overturn easily?
Car rollover is one of the serious accident situations, so what makes cars easy to rollover?
Road conditions
Bumpy, uneven roads, steep inclines or slopes are some of the causes of car rollovers. In addition, wet, slippery roads also pose many risks that cause the car to skid, lose control and roll over.
High speed driving
Driving at high speed is the most common cause of car rollovers. Since inertial force is proportional to speed, the higher the speed, the greater the inertial force. When inertial force is greater than gravity, the car is more likely to rollover. According to statistics from the National Highway Traffic Safety Administration (NHTSA), about 40% of car rollovers are related to high-speed driving. Of these, 75% of rollovers occur when the car is traveling at 80 km/h or more.
Using stimulants or alcoholic beverages while driving
Using stimulants or alcoholic beverages while driving will reduce the driver's ability to control situations, especially making it easier for the car to roll over.
Drivers in a state of drowsiness are more likely to violate traffic laws and take more risks, such as speeding or weaving in and out of traffic, endangering others around them.
Vehicle characteristics
In fact, any type of vehicle can roll over. However, vehicles with a high center of gravity are at a higher risk of rolling over. Accordingly, tall or high-chassis vehicles such as SUVs, pickup trucks, MPVs... are more likely to roll over than low-chassis vehicles such as sedans, hatchbacks...
Tire problems
Wheel slippage is also one of the causes of vehicle rollovers, especially SUVs or 15-seat trucks. When the vehicle has a tire blowout or flat tire, the driver will have a lot more difficulty controlling the vehicle. Therefore, vehicle owners should regularly check their tires to ensure safety.
Driving habits
According to the National Highway Traffic Safety Administration, more than 70% of rollover accidents are caused by the driver's habits at the time of the accident. Such as the habit of listening to music or talking on the phone, causing loss of concentration while driving.
