The Model Minimum Uniform Crash Criteria Guideline (MMUCC) is a minimum, standardized data set for describing motor vehicle crashes and the vehicles, persons and environment involved. The Guideline is designed to generate the information necessary to improve highway safety within each state and nationally. This data set, originally published in the MMUCC Guideline, 1st Edition (1998), has been revised twice in the MMUCC Guideline, most recently in the 3rd Edition (2008), in response to emerging highway safety issues.

The 107 data elements presented in this document include 75 data elements to be collected at the scene, 10 data elements to be derived from the collected data, and 22 data elements to be obtained after linkage to driver history, injury and roadway inventory data. Definitions for the data elements match existing standards, unless modification was necessary to match current trends.
