Rollover crashes
are the most dangerous
collision type for all
classes of light vehicles
Angelique Cintron, a 19-year
old student at Florida State University, was violently killed on November
7, 1997, in a single vehicle rollover accident involving her Kia Sportage
sport utility vehicle. Angie was on her way to her West Palm Beach
home for the weekend when, according to eyewitnesses, a black sports car
cut sharply in front of her on the Florida Turnpike south of Orlando.
She was forced to take evasive action at 70 miles per hour. Notwithstanding
her efforts to avoid a crash, her 1995 Kia Sportage rolled over approximately
6 times.
Angelique was wearing a seat
belt, but the roof crushed. She died of head injuries. Her
parents sued the South Korean car manufacturer alleging that the Sportage
is unsafe because it rolls over too easily, has a weak roof, and is marketed
unsafely to the public as a safe and stable passenger vehicle.
Kia denied that the Sportage
was prone to roll over or that it had an unsafe roof, contending that the
small SUV is safe, and that Angelique's death was caused by a combination
of the black sports car, Angelique's own alleged careless driving, and
the severity of the crash.
The West Palm Beach jury
disagreed: "It was a serious design failure in that car that failed to
protect the occupant," the jury foreman said.
Tab Turner and Ted Babbitt,
the attorneys for Angelique's parents, argued that several defects contributed
to the fatality: the collapsed roof, a windshield that popped out during
the roll, and an instability that caused the Sportage to roll in the first
place.
"They want to point their
fingers at everybody but themselves," Turner said.
The National Highway Traffic
Safety Administration (NHTSA) classifies sport utility vehicles (SUV) as
a light truck vehicle, along with pickups and vans. The agency has
recognized that rollover crashes are one of the most significant safety
problems for all classes of light vehicles, especially light trucks.

Crash data collected by NHTSA
from the various states indicate that in rollover crashes, light truck
vehicles are involved in 127% as many crashes as are passenger cars.
Analyzing these statistics from another perspective, according to a government
study, pickups and SUVs have a rollover rate that is 2-3 times higher than
the average passenger car. A study performed for the Motor Vehicle
Manufacturers Association has also recognized the significant difference
between rollover rates for passenger cars versus sport utility vehicles.
Statistics gathered between
1992-1996 reveal an average of 227,000 rollover crashes per year.
These rollovers resulted in an average of 9,063 fatalities per year and
more than 200,000 non-fatal injuries.
Rollover Resistance Rating
NHTSA's Rollover Resistence
Rating system {Star Rating System} is designed to measure vehicle characteristics
of the center of gravity and track width {T/2h}. The more narrow and tall
the vehicle is, the more susceptible it is to rolling over.

NHTSA's Star Rating System
Fatality Analysis Reporting
System (FARS)
According to the 1997 FARS,
almost 10,000 people were killed in light vehicle rollovers during that
year, including morethan 7,600 who died in single-vehicle rollovers.
FARS analysis shows that 53% of light vehicle occupant deaths in single-vehicle
crashes involved rollovers.
And the proportion is notably
different by vehicle type: 45% of car occupant fatalities in single-vehicle
crashes involved rollover, compared to 60% for pickup trucks, 65% for vans,
and 79% for SUVs.
These statistics support
the proposition that rollover crashes are the most dangerous type of collision
for all classes of light vehicles whether measured by fatalities or by
incapacitating injuries for each occupant. The data are even more
alarming when one considers that rollover accidents are the least frequent
crash mode per registered vehicle.
Buyer Beware:
When measured by either fatalities
or debilitating injuries for each occupant involved:
| • |
Rollovers
are second only to frontal crashes in their level of severity. |
| |
|
| • |
More
deaths result from rollovers than from side and rear crashes combined. |
| |
|
| • |
The greatest number of rollovers
occur in sport utility vehicles. |
| |
|
| • |
SUVs have a rollover rate
that is 2-3 times higher than the average passenger car.
