NHTSA supports the use of uniform crash report form data elements and encourages the use of ANSI D-16 and D-20 standards.  The purpose of ANSI-16, Manual On Classification Of Motor Vehicle Traffic Accidents, is to provide a common language for collectors and users of traffic crash data.  The purpose of ANSI D-20, Data Element Dictionary For Traffic Records Systems, is to provide a common set of element coding instructions as these relate to traffic safety, driver licensing and vehicle registration.

ANSI D16.1-1996 Manual on Classification of Motor Vehicle Traffic Accidents

NHTSA in collaboration with the Federal Highway Administration and the National Association of Governors’ Highway Safety Representatives has developed a guideline for crash data collection.  To facilitate this effort, an expert panel was formed consisting of Representatives from law enforcement, Emergency Medical Services, traffic engineering, departments of motor vehicles, academia, and a number of private organizations and groups interested in highway and traffic safety.  The guideline is referred to as the Model Minimum Uniform Crash Criteria (MMUCC).  MMUCC is intended to be a guideline for collecting crash data.  MMUCC is endorsed by a number of highway safety groups and organizations.  The final MMUCC was published in August 1998.
