In many vehicle rollover investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, roof crush and body-interior impacts. Obtaining answers often requires advanced roof structural analyses and three-dimensional computer simulations of the rollover motion itself. When analyzing a rollover accident, computer simulation is an invaluable tool, which allows us to model rollover motion and roof crush and can be used to create animations of the accident.

SUV Rollover:
An SUV lost control and traveled over a portion of highway guardrail before rolling down an embankment, destroying the roll cage's integrity. The defense theorized the driver was killed by intruding guardrail posts as the SUV rolled along the guardrail, and that a stronger roll cage design would not have protected him. We reconstructed the entire accident using computer modeling, which disproved the defense's theory and showed that the driver would have survived if the roll cage had been designed stronger.
SUV Rollover Ejection:
A woman driving an SUV was seriously injured when her vehicle rolled over due to the negligence of another driver. The SUV driver was ejected because she was unbelted. The defense claimed that, based upon statistical studies, she would not have been injured if she had been belted. We demonstrated that, her major injuries were caused by her impact with the door interior and would have been inflicted even if she had been belted and had not been ejected. The case settled in the plaintiff's favor.

While the information recorded on event data recorders (EDRs), commonly referred to as vehicle black boxes, is tremendously helpful in determining how a traffic accident occurred and in improving safety, it was not until recently that EDR data was legally challenged in Illinois and ultimately accepted

Forensic Engineering Experts: Animation
Animations are useful visual tools that can help jurors understand how an incident could, or could not, have occurred. Simply describing an event in court, or showing still pictures, may be insufficient to explain a complex sequence of events.

Forensic Engineering Experts: Seatbelts
Motor vehicle seatbelt use provides highly effective protection in frontal collisions for impact angles up to 30 degrees off-center (i.e. between 11 and 1 o’clock). All states have laws requiring their use for front seat passengers, as they have been shown to reduce moderate to severe injuries by 50%. They are less effective when your car is hit in the rear or side and sometimes their locking devices malfunction or the anchorage gives way.
