Find a Accident Reconstruction Expert →Overview
Accident reconstruction experts apply physics, engineering, and vehicle dynamics to determine how collisions occurred, who was at fault, and what injuries were mechanically plausible. They analyze scene evidence, damage patterns, tire marks, electronic data recorder (EDR) output, and sight-line geometry to reconstruct the pre-impact, impact, and post-impact sequence of events. These experts are among the most frequently retained in personal injury litigation because their analysis often directly determines liability in automobile, truck, motorcycle, and pedestrian cases. The premier credential is ACTAR (Accreditation Commission for Traffic Accident Reconstruction), earned by passing a two-part examination covering kinetic energy, momentum, airborne calculations, principal direction of force, tire evidence, and time-distance analysis, and maintained through 80 continuing education units every five years 1. SAE International publishes peer-reviewed technical standards — recommended practices for critical speed analysis, drag testing, and collision deformation classification — forming the scientific foundation for reconstruction opinions 2. Daubert courts scrutinize whether the methodology has been peer-reviewed, has a known error rate, and is generally accepted.
ACTAR accreditation requires passage of a two-part examination covering momentum, kinetic energy, airborne calculations, principal direction of force, and tire evidence, maintained through 80 continuing education units every five years.

FAQ
An accident reconstruction expert should hold ACTAR accreditation, have formal training in physics or engineering, demonstrate proficiency with industry-standard reconstruction software, and have experience testifying in court. Many have backgrounds in law enforcement accident investigation units.
Accident reconstruction experts are needed in any motor vehicle collision where the cause, speed, or sequence of events is disputed. This includes intersection collisions, rear-end impacts, rollover accidents, commercial truck crashes, and pedestrian or cyclist accidents.
In general, forensic expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic casework, academic qualifications, certifications, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
