Mi-CAT Overview

Effective November 1, 2021 the Traffic Crash Reporting Unit retired the Traffic Crash Reporting System (TCRS) which was previously access through Mi-Login. 

To replace this website, the TCRU has developed a new traffic crash analysis and visualization application called Mi-CAT (Michigan Crash Analysis Tool). Mi-CAT users receive access to up-to-date traffic crash data and statistics for all crashes that have occurred in Michigan. It can be used to query crash locations, view crash dashboards, create visualizations and charts, and search for UD-10 images.
