The Tennessee Highway Patrol’s Critical Incident Response Team (CIRT) is responsible for assisting other members of the Department in the investigation and reconstruction of motor vehicle traffic crashes. The unit is staffed with THP personnel and all members receive extensive training in traffic crash investigation.
The CIRT unit consists of four teams statewide, each covering two of the eight THP districts. A Lieutenant oversees command of the unit, and each team has a Sergeant who serves as the Team Supervisor. All of the teams are outfitted with the most advanced tools and equipment available to assist them in the investigation of traffic crashes and other incidents. This equipment includes the following:
Since the inception of the CIRT unit in April 2001, members have assisted in over 3,198 cases throughout Tennessee. While primarily responsible for internal investigations, CIRT has also assisted many local and federal law enforcement agencies as well as other state agencies. CIRT is also responsible for the investigation of all criminal homicides investigated by the THP.
