Did You Know?
The Accreditation Commission for Traffic Accident Reconstruction (known as ACTAR) was formed to implement a set of standards in the field of traffic accident reconstruction that were developed from a 1985 study commissioned by the National Highway Traffic Safety Administration (NHTSA). ACTAR is the standard professional accreditation body for accident reconstructionists. When you see the ACTAR seal affixed to a report (our report), you can be assured that the reconstructionist who prepared it is highly qualified in this specialized field. For more information on ACTAR, please click on the seal to the left.
