There are about 280,000 rollover accidents reported each year, which result in over 10,000 deaths annually, according to the National Highway Traffic Safety Administration (NHTSA). Sport utility vehicles (SUV's) are more likely to rollover when involved in an automobile crash because they carry heavier loads which make them top heavy and thus more likely to rollover.
Rollover accidents occur when a vehicle is unstable when making turns and traveling at high speeds. It has to do with the relationship between the center of gravity and the track width. When there is a lot of weight on the center of gravity it can cause the vehicle to rollover when making sharp turns or sharp changes in direction. Often, rollover accidents are a result of a flaw in the design of the vehicle and/or tires, or cause by the actions of another driver.
Most often rollover accidents occur when a driver loses control of a vehicle and it causes the vehicle to slide sideways and ultimately rollover. Sometimes the vehicle can hit a curb, guardrail, tree stump, or soft and/or uneven ground on the side of the road, causing the vehicle to rollover.
Rollover accidents are among the most serious and lethal of all motor vehicle accidents. These types of accidents come suddenly and without warning. Therefore; the NHTSA introduced a rollover rating system in 2001. The system reports rollover safety in a 5 star system. 5 stars equals a rollover risk of less than 10%, while one star indicates a 40% or greater rollover risk. Make sure and analyze the 5 star rollover rating system when purchasing your vehicle.
