The process involves analyzing human factors as well as physical facts using proven scientific principles. Initial Investigations: The investigation begins with an analysis of police accident reports and photographs, media coverage, on-site inspection and survey, vehicle(s) examination, witness statements and interviews. Site inspection includes analysis of marks on road, crash debris, vehicle fluid spills, line-of-sight surveys and road defects. All police marks should be identified, located by measurement and recorded. Dynamics of the vehicle must be analyzed including determination of speed, lines-of-travel, impact areas and crush stiffness coefficients. Analysis: A proper scientific analysis based upon verifiable fact and natural law is established. Crash factors may include: - Right of Way - Component Failure/Defect - Vision/Visibility - Stopping Distance/Brakes/Speed - Roadway Conditions - Human Factors - Vehicle Dynamics - Weather Conditions Text Box: Inspection and documentation of the vehicle condition may include inspection of vehicle components, recording of damage patterns and mechanical condition, determination of headlight, signal light or brake light condition at the time of impact, and/or compliance of vehicle condition with certification or regulatory standards Conclusions: An analysis of the incident is calculated by determining the motion and direction of the vehicles prior to the incident, the orientation and position of vehicles at impact and the vehicle speeds and dynamics prior to and after impact.

oImagine you are driving a 3 ton utility truck with a ¾ ton trailer carrying an 8 ton ditching machine and entering a right curve on a two lane highway.  You have driven this highway many times and were traveling 50 mph when you slowed for this curve which is followed by a downhill straight section ¼ mile long.  As you slowed the trailer started to “fishtail”.
