 Car Accident Reconstruction & Investigation

How Are Car Accidents Investigated?

Car accident claims require in-depth investigations to help determine the factors that contributed to the crash, including the mechanics, physics, driver behavior, and more. We at Scarlett Law Group are extremely familiar with the technology used to recreate and investigate accidents, and are able to represent complex car accident cases.

Investigation Phase

The first step is to conduct a thorough investigation collision and to collect evidence of the scene.

Some of the components of a car accident scene investigation can include:

  • Examination of vehicles involved in the collision
  • Documenting other objects involved, such as trees, buildings, etc.
  • Collecting traffic video or photographs of the scene
  • Reviewing eyewitness testimony and police reports

Use of Accident Reconstruction in Injury Trials

While liability for many vehicular/trucking collisions is clear, accident reconstruction and workup of the biomechanics of injury are nonetheless required in the proper trial presentation in virtually all such cases. The Scarlett Law Group works with top experts in the world on this subject. For example, many are surprised to learn that most SUVs and pickup trucks maintain a rigid bumper system which clearly can result in much greater injury to occupants in even low speed impact collisions.

Analyzing Bumper Damage

The presence or absence of motor vehicle bumper damage is usually thought to be an important consideration when estimating the severity of a low speed, or minimal damage collision.


  • Passenger cars: Most passenger car bumpers contain elements designed to dissipate the impact energy, such as shock absorber-like isolators, foam cores or lattice cores.
  • SUV and pickup trucks: A rigid bumper system, such as contained on most SUV and pickup trucks, typically consist of a steel bumper beam attached to the vehicle frame either directly or by mounting brackets. Rigid bumpers are common on pickup trucks, vans, and sport utility vehicles.

A number of studies have provided insight into analyzing collisions involving these kinds of bumpers.

  • In one study, full-scale impact testing was selected as a method of investigating the performance of rigid bumper systems during low-speed collisions. A vehicle-to-vehicle test is clearly the best facsimile of the actual collision. However, barrier impacts are widely used in mandatory standards compliant tests, and the relative ease of conducting a barrier test makes it an attractive alternative to a vehicle-to-vehicle test when assessing the behavior of a rigid bumper.
  • In at least one study, comparison was made between the damage produced in barrier and vehicle-to-vehicle test of a similar severity to assess the viability of barrier testing when analyzing real-world collisions involving rigid bumpers.

The Scarlett Law Group, together with its experts, maintains constant review of all literature in this area, and when re-enactment, via computerized projection or actual vehicle reenactment is performed for forensic purposes, the Scarlett Law Group and its expert chooses the most viable option available.
