Research and Data

We provide statistics and reports for other state agencies, as well as for the news media, private companies, and the public.

Our Research and Data Division (RADD) analyzes crash data and does traffic safety research. We also analyze the data that goes to the national Fatality Analysis Reporting System (FARS).
