Following a car accident, the job of experienced crash-scene investigator is to get answers about how a crash happened and who is responsible.
A very important part of the job is to identify the evidence at the scene and gather information that may be needed for an analysis or reconstruction or other technical work to determine the cause of a motor vehicle accident.
Iowa car-crash reconstructionists methodically process a scene of a car accident and use science and technology to forward their investigation:
- First, investigators working at the scene will try to find witnesses to the accident and take statements.
- During the initial on-scene investigation, crash-scene investigators look for evidence on the roadway such as tire marks and note the specific positions of the vehicles involved.
- Vehicles are examined to obtain further information. This may include finding evidence of alcohol or drug use, determining if seat belts were worn, collecting smart phones that may point to distracted driving or evidence of mechanical failure.
- Investigators may make several sweeps of the accident area gathering new clues and thoroughly photographing the scene so nothing is missed.
- In earlier days, investigators would sketch out a scene on a grid using a tape measure to reason out the physics of an accident. Today, laser technology provides 3-D virtual renderings of major accidents helping investigators recreate a scene. Available computer software can derive crash-time speeds.
When it is all said and done, investigators have a pretty good idea of how an accident occurred which they can use as evidence in court. Their findings can provide families of those injured in a car accident with information to help them understand what happened.
Reconstruction of car accident scenes provide many answers to the cause of Iowa car and truck accidents. Investigations reveal that being in a hurry is a factor as well as the fact that more motorist are on the roads. However, not surprisingly, distracted driving is one of the biggest factors in traffic crashes today.
