Single Vehicle Crashes – Rollover Accidents
Thursday, March 29th, 2012It makes no difference whether you are a driver or passenger, any auto accident is a frightening experience. A rollover accident, however, is one of the most dangerous. Why? Let’s start with the statistics:
- In 2002, there were 11 million crashes involving a passenger car, SUV, or pickup truck, and only 3% of those involved a rollover.
- More than 10,000 people died in those crashes, for a fatality rate of is 33%. Most of those victims (72%) were not wearing safety belts.
- Vehicles with a higher center of gravity, like SUV’s, vans, or pickup trucks, were more prone to rollovers in single vehicle crashes.
- The majority of all fatal rollovers were at speeds higher than 55 MPH, and 40% of those accidents involved speeding.
- 85% of all fatalities from rollover accidents were single vehicle crashes.
So rollovers have a higher fatality rate than other kinds of crashes, and usually involve only one vehicle. How do these terrible accidents happen?
The National Highway Traffic Safety Administration (NHTSA) describes two causes for a rollover and divides them into 2 categories; tripped rollovers and un-tripped. Here’s the difference between the two.
A Tripped Rollover is just what its title describes. The vehicle “trips” or “stumbles” over something and falls over itself. Almost all (95%) of single-vehicle rollovers are tripped. The vehicle may go off the road, slide sideways, and its tires hit something, causing it to stumble and roll. It can be something as simple as soft soil, a change in slope, or even a guard rail.
Sometimes, a vehicle traveling on a highway drifts into another lane, the driver quickly makes a steering correction and over corrects. Then the tires hit the soft soil on the shoulder and the vehicle trips, causing it to rollover. It’s not just soft soil that can do this; it could be a guardrail, or curb, snow bank or just about any object.
Tripping also can happen on a steep slope. A vehicle may be going down a steep hill and start to pick up speed. The driver misjudges the steepness of the hill, and any turn or correction is too much at the traveling speed. The vehicle rolls over and tumbles down the hill.
An Untripped Rollover is much less common. These type of accidents occur less than 5% of the time, and happen most often in vehicles that are top-heavy. An untripped rollover usually happens when a driver is trying to avoid a crash, and over corrects. Often the vehicle is heavily loaded and the weight of the cargo causes the vehicle to be top heavy and rollover.
Rollovers are violent, tragic crashes. More often than other types of crashes, they are caused by driver behavior, road conditions, and environmental factors. Too often it’s a correction after a brief distraction. Now that you know how how fatal a single car rollover can be, use extra caution to avoid an accident.
