The Indiana Criminal Justice Institute uses National Highway Traffic Safety Administration funding to partner with the Indiana University Public Policy Institute (IUPPI) to analyze ARIES crash data for each calendar year. Research findings are summarized in a series of Crash Facts publications. Indiana code requires a law-enforcement officer to investigate and submit a written report for each motor-vehicle crash that results in injury, death or property damage of at least $1,000. Indiana Officer’s Standard Crash Reports are submitted electronically using the Automated Reporting Information Exchange System (ARIES).
Crash Fact Books
This publication provides an in depth view of Indiana crashes, incorporating the more than 200 data items collected from officer crash reports submitted via ARIES and maintained by LexisNexis Risk Solutions and the Indiana State Police. The publication was prepared by the traffic safety research team at the Indiana University Public Policy Institute on behalf of ICJI.
County-level Crash Data
Each year, the traffic safety research team at the Indiana University Public Policy Institute prepares a report for ICJI summarizing detailed crash characteristics for each of Indiana’s 92 counties.
Topical Fact Sheets
ICJI partners with IUPPI researchers to prepare an annual series of fact sheets on various aspects of Indiana traffic collisions, including alcohol-impaired driving and other dangerous driving behaviors, seatbelt use, child passenger safety, motorcycles, young drivers, non-motorists, and commercial vehicles. Fact sheets summarizing the most recent data available (2019) are provided below.
