Crash Preventability Determinations

FMCSA will review Requests for Data Reviews (RDRs) submitted into the Crash Preventability Demonstration Program in the order received. If FMCSA reviews a crash and determines it to be not preventable, the Agency will post a notification of the preliminary determination on DataQs for 30 days. During this time, anyone with documentation or data to refute the preliminary determination may go to DataQs and submit documentation that should be considered before a final determination is made.

FMCSA’s Safety Measurement System (SMS) will display the final determinations of reviewed crashes.

  • Not Preventable: The crash will appear on the public display of SMS with a notation that reads “FMCSA reviewed this crash and determined that it was not preventable.”
    • The Crash Indicator BASIC on the motor carrier and enforcement views of SMS will display calculations with and without the not preventable crashes.
  • Preventable: The crash will appear on the public display of SMS with a notation that reads “FMCSA reviewed this crash and determined that it was preventable.”
  • Undecided: If the documentation provided with the RDR does not allow for a conclusive determination, the crash will appear on the public display of SMS with a notation that reads “FMCSA reviewed this crash and could not make a preventability determination based on the evidence provided.”

Determinations made during the Crash Preventability Demonstration Program will not impact FMCSA’s other systems.
