Crash Data

CDOT maintains a crash database for the purpose of improving traffic and highway safety as required by 23 U.S.C. Section 148 and 23 U.S.C. Section 405. All crash data listings, reports and dashboards are protected under 23 U.S.C. Section 407.

Disclaimer: All crash data post 2020 is subject to revision and change.

Crash Data Dashboards

Transportation safety is a top priority for Colorado. CDOT Traffic Safety & Engineering Services developed performance dashboards displaying all reporting public roadway crashes in Colorado to better understand numbers, causes, types, and locations of crashes in order to develop effective countermeasures and meet performance targets.

Disclaimer: Colorado traffic crashes as presented in the dashboard should be regarded as preliminary and subject to change. Please consult the Fatal Crash Page for the official and most current count of traffic fatalities in Colorado.

Requesting Specific Crash Data

More specific crash data requests (intersection, corridor, city, county, etc.) can be provided through an open records request (typically in excel format). Local agencies and MPOs/TPRs can contact CDOT directly for crash data within their own jurisdiction. When requesting, please provide specific location(s) and date ranges (e.g., January 1, 2019 - December 31, 2021) or state the desired number of years of the most recent available crash data (up to five years). CDOT does not release personal identifying information including names, driver’s license numbers, addresses, birth dates, license plate numbers, VIN numbers, local and state identifiers such as case numbers, etc.

For requests of individual crash reports, requests should be sent through the Department of Revenue (DOR). CDOT is not the legal custodian of these records and will refer requests to DOR. Copies of original crash records may also be available directly from the responding law enforcement agency.

Process

When a crash occurs, after an officer investigates and fills out a crash form (DR3447), the form is sent to the Department of Revenue (DOR). DOR processes the records and enters them into a database called DRIVES where the official, legal record is maintained. CDOT receives data from the DRIVES system for all crashes, excluding private property and counter reports. (Counter reports are self‐reported by drivers and are not investigated by a law enforcement officer).

CDOT has a process that enhances the crash data received from DOR so that data can be used more efficiently for engineering and research purposes. This process adds an additional field for crash type, corrects common errors, updates the location information where available, and normalizes the data. This cleansing process creates a working database that CDOT then uses for engineering safety analysis and evaluation of safety for infrastructure projects. Some examples of how this data is used is to assess Level of Service of Safety (LOSS) for highway segments and intersections, identification of crash patterns, statewide strategic safety planning, evaluation of safety performance measures, and development of crash prediction models and diagnostic norms.
