Traffic Crash Dictionaries
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.
