Crash data

Crash records contain data from the Police Traffic Collision Reports, i.e., date and time of collision, location, contributing circumstances, weather, etc. as well as data derived from the officer's narrative and diagram (collision type, object struck, junction relationship, etc.).  Our retention for crash data is 15 full years, plus the current year.  Crash data is not considered complete or finalized until July of the following year it was collected.  Example: 2024 crash data is considered finalized in July 2025.
