The Crash Reconstruction Program uses the latest equipment to map crashes and crime scenes and collect evidence. Survey equipment such as the Nikon NPR-332 total station and LTI laser with angle encoder, Vericom performance computers, digital cameras, drag sleds, and tape measures are used by CRP reconstructionists. Crash and crime scenes are mapped using total stations, triangulation, and base line offset techniques. The CRP currently uses the latest version of Crash Zone and AR Pro software. CRP reconstructionist's provide Idaho POST certified instruction in Basic and advanced crash investigation to law enforcement officers statewide through the POST academy and to ISP officers and cadets through the Idaho State Police training section.

The Crash Reconstruction Program utilizes peer review, standardized procedures, and a standardized reconstruction report format. The CRP provides continuing education and training to its current reconstructionists and implements selection criteria and testing for new candidates. The CRP is managed by a program coordinator who ensures quality control and facilitates day to day operations for the program.
