What is "Accident Reconstruction"?
An "accident" is defined as "an unexpected and undesirable event". Accident reconstruction involves determining how and why an accident happened - accomplished first by correctly interpreting the clues left by the remaining physical evidence of the accident, then by reconstructing and studying the events both preceding and following the accident.
A peculiarity of this profession is that accident investigations are methodically worked backwards, time-wise - from the end results back to the beginning sequence of events.
All kinds of accidents can be investigated through reconstruction methodology plane crashes, crane failures, bridge collapses, vehicular collisions, etc.
Reconstructions of traffic collisions, specifically, typically involve determining the factors which contributed to the cause and severity of the collision, such as excessive speed, poor visibility, a defective tire, the failure of an occupant to wear a safety belt, or the disregard of traffic control devices.

We find it fascinating how many "Accident Reconstruction" sites are nothing but a bunch of over paid engineers with no or little actual experience in this type of critical work. Here we are talking about the lives off all those left behind, those that are permanently disabled or those that died and you actually get an attorney who goes out and hires a company with no actual experience!
