Effective July 27, 2017, the Federal Motor Carrier Safety Administration (FMCSA) announced a crash preventability demonstration program to evaluate the preventability of eight categories of crashes through submissions of Requests for Data Review to its national data correction system known as DataQs. On August 5, 2019 (84 FR 38087), after 18 months of operating the program the decided to operate a crash preventability determination program, using a streamlined process, and proposes to modify the Safety Measurement System to remove crashes found to be not preventable from the prioritization algorithm and noting the not preventable determinations in the Pre-Employment Screening Program. In addition, FMCSA proposes to consolidate two of the original crash types in the demonstration program and start reviewing additional crash types to determine if crashes in the additional categories are predominantly not preventable. FMCSA seeks comments on its implementation of these changes and on the new crash types. Comments must be received on or before October 4, 2019.
