MMUCC Guideline: Model Minimum Uniform Crash Criteria, Fifth Edition (2017)

The use of State crash data is often hindered by a lack of uniformity. Sharing and comparing data between localities, States, and the federal government can be very difficult when the data elements used by separate agencies to describe the same crash characteristic have different definitions or attributes. To encourage greater uniformity, a voluntary data collection guideline was developed cooperatively by the National Highway Traffic Safety Administration (NHTSA) and the Governors Highway Safety Association (GHSA) in 1998. The Model Minimum Uniform Crash Criteria (MMUCC) guideline identifies a minimum set of motor vehicle crash data elements and their attributes that States should consider collecting and including in their State crash data systems. Typically, the data elements and their values (attributes) describe who was involved, where the crash took place, when and under what circumstances it took place, what the impacts of the crash were, and why the crash happened. A number of important changes were made in this edition. States are given more flexibility in how they collect crash data. Elements were rearranged into four distinct sections to streamline the collection of more detailed information on fatal crashes, crashes involving commercial motor vehicles or vehicles placarded as carrying hazardous materials, and crashes involving non-motorists. A new type of data element—the dynamic data element—is introduced for the first time to capture data on topics that are changing rapidly.
