Summary

This report, titled *Indiana Crash Facts 2007*, provides a comprehensive statistical analysis of traffic collisions in Indiana to inform policy-making and safety program design. Produced by the Indiana University Public Policy Institute’s Center for Criminal Justice Research in collaboration with the Indiana Criminal Justice Institute, the document utilizes data from the Indiana State Police’s Automated Reporting Information Exchange System (ARIES). The primary objective is to assess the state of traffic safety against benchmarks established by the National Highway Traffic Safety Administration (NHTSA), focusing on priority areas such as alcohol involvement, safety belt usage, young drivers, motorcycle safety, and dangerous driving. The methodology involves analyzing detailed crash reports containing over 200 data items per collision, including date, location, vehicle types, and driver conditions. The report aggregates this data to identify trends from 1998 to 2007, comparing Indiana’s statistics with national averages. It examines specific variables such as blood alcohol content (BAC), restraint use, age demographics, and collision severity. The analysis serves as an analytical foundation for the Indiana Strategic Highway Safety Plan, providing evidence-based metrics to evaluate the effectiveness of current safety initiatives and to set future performance goals. Key findings for 2007 indicate a 6.4 percent increase in traffic-related collisions resulting in injury or property damage, totaling 205,005 incidents. There were 898 fatalities in 804 fatal collisions, a slight decrease from the previous year. Alcohol-related collisions accounted for 4.8 percent of all collisions and 28.9 percent of fatal collisions, representing a decrease from 2006 levels. Speed was a factor in 9 percent of all collisions and 20.5 percent of fatal collisions. The report highlights that 70.4 percent of fatal collisions occurred in rural areas, while 64.6 percent of all collisions occurred in urban areas. Young drivers aged 18 to 20 exhibited the highest rate of driver fatalities per 10,000 licensed drivers. Additionally, only 43.4 percent of persons killed in motor vehicle collisions were known to be restrained, and the economic costs of crashes exceeded $4.5 billion. The significance of this report lies in its role as a critical resource for state and national policymakers. By identifying specific problem areas, such as the high rate of unrestrained occupants and the prevalence of alcohol and speed in fatal crashes, the document supports targeted interventions. It establishes short- and long-term goals for reducing fatalities and injuries, such as lowering the traffic fatality rate per 100,000 population and increasing seat belt usage. The data underscores the need for continued enforcement and education programs, particularly regarding impaired driving and occupant protection, to mitigate the substantial human and economic costs associated with traffic crashes in Indiana.

Key finding

Alcohol-related collisions accounted for 28.9 percent of all fatal collisions in Indiana in 2007, while drivers aged 18 to 20 experienced the highest fatality rate per 10,000 licensed drivers.
