Model Minimum Uniform Crash Criteria (MMUCC) 5.0

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 5th Edition (2017), in response to emerging highway safety issues and other highway safety needs. The data elements presented in this document include data elements to be collected at the scene, data elements to be derived from the collected data, and 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. (See MMUCC website at https://www.nhtsa.gov/mmucc-0.)
