|Rollover Traffic Accident
Rollover crashes are one of the most dangerous traffic accidents to be involved in. 63% of rollover crashes involve
some type of injury to an occupant, while 18% of rollover accidents involve a fatality.
And while any person can be involved in a rollover accident, as a group, drivers between the ages 16-24 are
significantly more likely to roll over than drivers over age 24.
Accident reconstruction experts have shown that many traffic crashes involving a rollover require some type of
tripping mechanism to induce a vehicle into a roll. A tripping mechanism can be a collision with another motor
vehicle, a steep downward slope on soft earth, or a curb.
That said, a tripping mechanism is not always required to cause a rollover accident. Instead, inappropriate
steering inputs, such as overcorrection, can also cause a vehicle to roll.
Although the cause of a rollover can vary, almost all rollover crashes involve a loss of control with about 75 % of
those control loss cases occurring on icy, wet, or snowy roads.
Due to the high propensity for injury during a rollover crash, the National Highway Traffic Safety Administration
(NHTSA) now offers a rollover rating in addition to their 5-star crash evaluation system.
In addition, many auto manufacturers are now installing rollover sensors (ROS) to aid in the protection of
occupants through side and head curtain airbag deployment. In some cases, our accident reconstruction experts
can download and interpret the crash data from a ROS sensor when investigating the cause of a rollover crash.
For a vehicle to overturn without tripping,
the lateral acceleration (a) in Gs must exceed the value of one half the
track width of the vehicle (w) divided by the center of gravity height of the
The above illustration displays a rollover
collision wherein the depicted vehicle side
slips into a low lying curb.
The curb acts as a tripping mechanism, causing
the top of the vehicle to roll over.
Accurate reconstruction of vehicle roll mechanics
is crucial in understanding how a vehicle was
damaged and the occupants were injured.
