A dangerous driving collision is defined as any collision where a driver takes one or more of the following actions: aggressive driving, disregarding a signal, or speeding (see last page for a full list of definitions, references, and data sources). This fact sheet summarizes Indiana dangerous driving data trends at state and county levels. Collision data come from the Indiana State Police Automated Reporting Information Exchange System (ARIES), as of March 17, 2016.

The annual count of Indiana collisions involving dangerous driving decreased for the first time since 2012 (from 31,228 collisions in 2014 to 28,610 collisions in 2015) (Figure 1). Dangerous driving collisions accounted for 13 percent of all Indiana crashes in 2015, a 2 percentage point decrease from 2014
