Missouri State Highway Patrol

Major Crash Investigation Unit

The Patrol currently has twenty officers assigned to five Major Crash Investigation Units, located strategically throughout the state. The primary mission of the MCIU is to investigate and provide detailed reporting of serious crashes involving fatalities, commercial motor vehicles and crashes resulting in felony criminal charges. The crash teams also assist other law enforcement agencies with serious traffic crash investigations and critical crime scene mapping. The teams utilize Robotic Total Station technology, which allows for the accurate and fair depiction of crash and crime scenes diagrammed to scale. Each officer is trained in the human, mechanical and environmental factors of traffic crash investigation. They are considered court experts in the field of traffic crash investigation.

Each member of the MCIU is an ACTAR certified crash reconstructionist. The Accreditation Commission for Traffic Accident Reconstruction (ACTAR) is an internationally recognized commission with approximately 700 ACTAR Accredited Reconstructionists practicing throughout the United States, Canada, Australia, Singapore and United Arab Emirates. These Accredited Reconstructionists are engineers, physicists, police officers, consultants, former police officers and those of other backgrounds working in the profession.
