When Should Counsel Consider Retaining a Collision Reconstruction Expert?
A collision reconstruction expert should be retained as early as practical after a collision. Early involvement helps preserve physical and electronic evidence before vehicles are repaired, scrapped or altered, and allows the specialist to advise on what information and access will be needed.
Why Timing Matters
Physical and electronic evidence can be lost quickly after a collision. Roadway evidence fades, vehicles are repaired or salvaged, and electronic data can be overwritten. Retaining a reconstructionist early helps ensure that the evidence needed for a reliable analysis is documented and preserved before it is gone.
When Reconstruction May Be Relevant
Reconstruction may be relevant when technical questions about how a collision occurred are important to a civil or criminal matter — for example, questions about vehicle speed, the sequence of events, or the factors that contributed to the crash. An attorney can advise on when expert analysis or testimony is appropriate for a specific case.
What Information Helps a Reconstructionist
Helpful information includes the date and location of the collision, the vehicles involved (make, model, year and VIN where available), a description of the collision, the location and condition of the vehicles, and any available scene photographs, video or reports. For commercial vehicles, engine and braking-system information is also useful.
Reconstruction Does Not Guarantee an Outcome
Reconstruction provides objective technical information about how a collision occurred. It does not guarantee any specific legal outcome, and it does not determine legal liability — that is the role of the court or jury. The conclusions a reconstructionist can reach depend on the evidence that exists.
