An accident reconstruction expert applies physics and engineering principles to establish speeds, positions, timing, impact sequence, and avoidability. Inputs include scene measurements, tire marks, vehicle damage, event data recorder output, and photographs.
Qualification typically rests on engineering training, law enforcement reconstruction certification, or both.

Why it Matters?
Reconstruction opinions now stand or fall on their consistency with recorded data. An expert whose speed calculation conflicts with the engine control module output faces both a damaging cross-examination and a viable Rule 702 challenge on reliable application. That dynamic has raised the value of early data preservation, since the reconstruction depends on evidence that degrades within days.
