NHTSA makes a number of resources available for states and the public on its website, including program guidance, assessments, technical assistance and information about its traffic records program.
Model Minimum Uniform Crash Criteria
6th Edition Update
The Model Minimum Uniform Crash Criteria (MMUCC) is a minimum, standardized data set for describing motor vehicle crashes and the vehicles and persons involved. By providing a "minimum" set of data elements, MMUCC helps states collect reliable crash data, effectively guide enforcement planning, and shape sound traffic safety policy. This data set, originally published in 1998, has been revised four times, most recently in the 6th Edition (2024), in response to emerging highway safety issues. GHSA has helped manage these updates with funding from NHTSA.

Best Practices
GHSA, under contract with NHTSA, produced a guidance document to characterize more accurately, both quantitatively and qualitatively, the states’ progress in adopting the MMUCC elements. It also highlights promising practices and provides concrete examples that SHSOs can use to support their own efforts to improve crash data collection and integration with other critical data sets.
