The documentation below provides a description of each data variable in the NMDOT crash database. The database consists of three levels of data:  

  • Crash-level data contains information about the entire crash, such as crash location, crash date, total fatalities in the crash, and whether alcohol was involved in the crash.  
  • Vehicle-level data contains information about each vehicle and driver in the crash, such as driver age, driver alcohol-involvement, and vehicle type.  
  • Occupant-level data contains information about all people in crashes, such as age and belt usage.  

The NMDOT crash database is compiled using the Uniform Crash Report, a statewide form submitted by the many law enforcement agencies in the state to NMDOT for any crash on a public roadway involving one or more motor vehicles that resulted in death, personal injury, or at least $500 in property damage. No account is kept of unreported crashes, and the database does not include crashes on private property.  


NMDOT crash data is protected by federal mandate Title 23 U.S.C. Section 409 which forbids the discovery and admission into evidence of reports, data, or other information compiled or collected for activities required pursuant to federal highway safety programs, or for the purpose of developing any highway safety construction improvement project, which may be implemented utilizing federal-aid highway funds, in tort litigation arising from occurrences at the locations addressed in such documents or data.
