Request for Comment; Draft Model Minimum Uniform Crash Criteria (MMUCC) Guideline, Sixth Edition

The Model Minimum Uniform Crash Criteria (MMUCC) provides States a guideline for describing crashes involving motor vehicles in-transport to generate the information necessary to improve traffic safety. The primary benefit of using MMUCC is increased crash data uniformity so traffic safety insights can be developed more quickly. Since its inception in 1998, MMUCC has been a voluntary guideline for States; however, standardization of crash data is essential to NHTSA and its safety stakeholders. The crash data that NHTSA obtains from the States supports several of NHTSA’s efforts such as the Fatality Analysis Reporting System (FARS) and the Crash Report Sampling System (CRSS), which are essential to NHTSA’s traffic safety activities as well other Federal, State, and local agencies. Therefore, it is critical that the recommended MMUCC data elements be designed with clarity, purpose, and feasibility. NHTSA is revising the Model Minimum Uniform Crash Criteria (MMUCC) 5th Edition and requests comments on the draft MMUCC Guideline, Sixth Edition to inform appropriate improvements and identify stakeholder concerns.
