About Our Experts
Fraud Investigation
Each year, approximately 160,000 people are involved in
side impacts with fixed roadside objects.
- NHTSA
In the United States, collisions with fixed objects and non-collisions account for only about 19% of all
reported crashes, yet they result in 44% of all fatalities.

Accident reconstruction data reveals that trees and utility poles are by far the most frequently struck
objects.  A collision with one of these two fixed objects results in the highest risk of injury and, therefore,
are the objects causing the greatest loss to society.  

Experts estimate that accidents involving fixed objects represent a loss to our society of about $3 billion
each year.

And while the type of object that is struck often predicts the severity of subsequent injuries, there are
other variables which can affect the outcome of a fixed object crash, which include driver characteristics,
such as size or age of the driver.  

Certain types of traffic violations are also strongly associated with fixed object crashes.

For example, driving over the speed limit and driving under the influence of alcohol increase the
probability of being in a fatal fixed object accident.  And, not surprisingly, drivers that do not use seatbelts
are associated with an increase in the probability of more severe injuries, even when an airbag is
deployed.

When a vehicle strikes a fixed object, some of its kinetic energy (energy due to motion) is converted into
work, or in this case, vehicle deformation and fixed object damage.

Our accident reconstruction experts employ a variety of investigative measures, including energy
analysis,  to explore, determine and evaluate the events leading up to a fixed object crash.
Vehicle type and maximum crush depth can be used by
experts to estimate a vehicle's barrier equivalent velocity via
empirically derived accident reconstruction formulas, such
as Victor Craig's narrow object crush equation.
Scene evidence, such as skid marks or yaw marks are often
an intricate part of determining the pre-impact motion of a
vehicle before a fixed object collision.
