Aaron (Al) Duncan II, ACTAR, is a Vehicle Collision Reconstructionist with Warren. He is accredited as a Traffic Accident Reconstructionist by The Accreditation Commission for Traffic Accident Reconstruction.
Background Experience - Prior to joining Warren, Mr. Duncan worked for 23 years as a South Carolina Highway Patrol Trooper to include 10 years as a Multi-Disciplinary Accident Investigation Team (M.A.I.T.) member. As a trooper, he investigated in excess of 1,000 vehicle accidents and incidents. Then, as a member of M.A.I.T. for 10 years, he was involved in over 1,000 detailed investigations and collision reconstructions. Mr. Duncan is a member of the South Carolina Association of Reconstruction Specialists (SCARS), the International Association of Accident Reconstruction Specialists (IAARS), and the Blue Knights International Motorcycle Group. He holds a Bachelor of Science Degree in Political Science from Lander University in Greenwood, South Carolina and completed the Law Enforcement Basic Program at the South Carolina Criminal Justice Academy in Columbia, South Carolina.
Mr. Duncan has testified multiple times in state courts and he has been court qualified as an expert in accident investigation and collision reconstruction. His expertise focuses on investigating and reconstructing vehicle collisions involving single and multi-vehicles, animals, pedestrians, motorcycles, heavy trucks, and commercial vehicles. Mr. Duncan is also a skilled user of Forensic Mapping Technology and Computerized Collision Diagramming Software for collision scene analysis. He is experienced in the data download and analysis of airbag black boxes (Crash Data Retrieval Units) in automobiles, pickup trucks, and SUVs.
Areas of Expertise:
- Crash Data Retrieval
- Forensic Mapping Technology
- Vehicle Collision Reconstruction
In my 25 years of investigating collisions and traffic related incidents, one thing I have noticed repeatedly is that right turns are considerably better than lefts. I know it is obvious and sometimes seems a little petty; however, when it comes to the safety of your family, it is a big deal. Since I am currently in the process of teaching my second child how to drive, I am harping on vehicle safety a lot and this is one of the many practices I teach. I have instilled in my children (and my wife has picked up on it as well) that they should always plan out their route and, in doing so, make right turns instead of lefts whenever possible. The “Right Turn Only” practice will make your travels safer.
Event Data Recorders (EDRs) were first introduced by General Motors (GM) in 1974. That data was only available to GM; however, since 1994 more and more vehicle EDR’s have recorded data that can be gathered. The data captured can be imaged and is being used by vehicle manufacturers, law enforcement officers, and collision reconstructionists to better understand what is happening in a collision. In accident investigation, EDRs have the potential to provide independent measurements of crash data that would elsewise be estimated by reconstruction methodology.
