The State Serious Injury Conversion Tables were compiled by the National Highway Traffic Safety Administration (NHTSA) using State Motor Vehicle Crash Manuals to assist States in reporting serious injuries as required by FHWA's Safety Performance Management Measures Final Rule (23 CFR 490) and NHTSA's Uniform Procedures for State Highway Safety Grant Programs Interim Final Rule (23 CFR 1300). These two regulations require that serious injuries be reported per the Model Minimum Uniform Crash Criteria (MMUCC) 4th Edition attribute for "Suspected Serious Injury (A)" as defined in the "P5. Injury Status" element.
States that do not currently use the MMUCC 4th Edition attribute for "Suspected Serious Injury (A)" shall use the State Serious Injury Conversion Tables until April 15, 2019 to convert the equivalent definition and attributes from their State's Motor Vehicle Crash Database for the purpose of reporting safety performance measures beginning with the 2017 Highway Safety Improvement Program (HSIP) Annual Report and the 2018 Highway Safety Plan (HSP). However, it is recommended that States begin using the MMUCC 4th Edition definition and attributes beginning January 2019 in order to have a complete and consistent data file for the entire 2019 calendar year.
Additionally, the tables provide the equivalent definitions for pedestrian and pedalcyclist as defined in the American National Standard Institute (ANSI) D16.1-2007 Manual on the Classification of Motor Vehicle Traffic Accidents in order for States to report the required number of non-motorized serious injuries in the HSIP Annual Report
Please refer to the FAQs and Instructions for additional information on using the State Serious Injury Conversion Tables.
