Model Minimum Uniform Crash Criteria (MMUCC) Guideline. Third Edition

The purpose of the Model Minimum Uniform Crash Criteria (MMUCC) is to provide a dataset for describing crashes of motor vehicles in transport on a roadway that will generate the information necessary to improve highway safety within each State and nationally. Efforts to standardize crash data have increased since the MMUCC was originally recommended as a voluntary guideline in 1998. The MMUCC data elements represent a core set of data elements, most of which were being collected by the States before the first edition of the MMUCC Guideline was published. The 111 data elements contained in the MMUCC Guideline, 2nd Edition (2003) were revised in response to emerging issues and other highway safety needs. The third edition of the MMUCC Guideline contains 107 data elements. Only one new data element, Bus Use, was added to the third edition of the MMUCC Guideline. The MMUCC Guideline, 3rd Edition (2008) recommends that States implement all 107 data elements included in this document. To reduce the data collection burden, MMUCC recommends that law enforcement at the scene should collect 75 of the 107 data elements. From crash scene information, 10 data elements can be derived, while the remaining 22 data elements should be obtained after linkage to other State data files. States that are unable to link to other State data to obtain the MMUCC "linked" data elements should collect, at a minimum, those "linked" data elements that are feasible to collect on the crash report. At the same time, States should work to develop data linkage capabilities so they eventually are able to obtain, via linkage, all of the information to be generated by the MMUCC "linked" data elements. Because State datasets and systems are difficult to implement or change, no changes will be made to the MMUCC Guideline, 3rd Edition (2008) for five years. During this period, each of the data elements and their attributes will be monitored to determine their usefulness and reliability.
