Research & Data

Our Research and Data Division (RADD) analyzes crash data and conducts traffic safety research. RADD codes the fatal crash data that goes to the national Fatality Analysis Reporting System (FARS). We provide statistics and reports for other state agencies, as well as for the news media, private entities, and the public.

About RADD

RADD manages Washington’s Fatality Analysis Reporting System (FARS), a census of all traffic fatalities occurring on Washington roadways. Find out more about Washington’s collision data sources and why there are sometimes differences in the number of deaths we report and the number reported by other agencies.
