The Fatality Analysis Reporting System (FARS) 2022 Final Release - Fatal Motor Vehicle Accidents Auxiliary File dataset was compiled from January 1, 2022 to December 31, 2022 by the National Highway Traffic Safety Administration (NHTSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The final release data is published 12-15 months after the initial release of FARS, and could contain additional fatal accidents due to the delay in police reporting, toxicology reports, etc., along with changes to attribute information for previously reported fatal accidents. This file contain elements derived from the FARS datasets to make it easier to extract certain data classifications and topical areas. This file downloaded from the open data catalog is synonymous with what USDOT/NHTSA releases for FARS as the ACC_AUX file. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529020
