| SUVs are more than 2 1/2 times more likely to rollover in a collision than non-SUV vehicles. - NHTSA |
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 vehicle (h).

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.
