State Serious Injury Conversion Tables
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.
If States are not already using the MMUCC 4th Edition attribute for “Suspected Serious Injury (A)" for reporting serious injuries, they may use the State Serious Injury Conversion Tables until April 15, 2019. FHWA and NHTSA recommend that States adopt the MMUCC 4th Edition definition for Suspected Serious Injury (A) as soon as possible or at least by January 1, 2019 to produce a consistent and compliant data set for an entire 2019 calendar year.
In addition, States that do not use the ANSI D16.1 standard to define seriously injured person types for pedestrian and pedalcyclist may use the State Serious Injury Conversation Tables to convert the equivalent person types from the State Motor Vehicle Crash Database to report non-motorized serious injuries.
