NHTSA works to ensure that complete, accurate, and timely traffic safety data are collected, analyzed, and made available for decision-making at the national, State, and local levels. Analyzing reliable and accurate traffic records data is central to identifying traffic safety problems and designing effective countermeasures to reduce injuries and deaths caused by crashes.
NHTSA’s National Driver Register and Traffic Records Division provides coordinated guidance, outreach, best-practices, and training and technical assistance designed to improve the timeliness, accuracy, completeness, uniformity, integration, and accessibility of State crash, driver, vehicle, roadway, citation and adjudication, and injury surveillance databases. The Traffic Records Team is tasked with helping States improve their traffic safety data collection, management, and analysis capabilities through evaluation, training, and technical assistance.
Traffic Records Assessment
NHTSA’s assessments are peer evaluations of State traffic records system capabilities. Using the online State Traffic Records Assessment Program (STRAP), independent subject matter experts from State, local, and other areas examine State responses to a uniform set of questions and rate the responses against the ideal set out in the Traffic Records Program Assessment Advisory. The final report includes these ratings, recommendations, and considerations that the States may consider in working to improve their traffic records system performance.
Crash Data Improvement Program (CDIP)
NHTSA’s CDIP technical assistance program examines the quality of a State’s crash data and provides the State with specific recommendations to improve the quality, management and use of that data to support safety decisions. This program is free to the States and made available on a first-come, first-served basis given available funds. States that wish to request a CDIP at no expense should complete the "Application for Traffic Records Programs" found in the additional resources at the top-right of this page, and submit to their regional NHTSA office.
NHTSA’s Traffic Records GO Team program is designed to provide resources and assistance to State traffic records professionals as they work to better their traffic records data collection, management, and analysis capabilities. GO Teams are small groups of one to three subject matter experts designed to help States address traffic records issues. States that wish to request a GO Team at no expense should complete the "Application for Traffic Records Programs" found in the additional resources at the top-right of this page, and submit to their regional NHTSA office.
Model Minimum Uniform Crash Criteria
The Model Minimum Uniform Crash Criteria (MMUCC) Guideline, Fifth Edition (2017), is a voluntary guideline designed to help States determine (minimally) what crash data to collect on each reportable crash. Additionally, NHTSA and the Governors Highway Safety Association (GHSA) developed a standardized methodology for mapping State crash data to MMUCC, MMUCC Mapping Rules, which is incorporated into the new edition. The new MMUCC website is located at www.nhtsa.gov/mmucc. States that wish to request a MMUCC Mapping at no expense should complete the "Application for Traffic Records Programs" found in the additional resources at the top-right of this page, and submit to their regional NHTSA office.
