NHTSA Crash Report Sampling System (CRSS) National Files

Annual public-use national probability-sample files for eligible police-reported motor-vehicle traffic crashes. Coordinated crash, vehicle, person, event-sequence, related-factor, weather, vPIC-derived, and auxiliary tables are pinned to the 2024 first final release dated 2026-04-01. CRSS is not a census or arbitrary-event lookup; estimates require its survey-design fields.
