FMCSA’s Crash Preventability Determination Program (CPDP) reviews 21 specific crash types and modifies information in the Agency’s Safety Measurement System (SMS) to distinguish not preventable crashes. Under the CPDP, if you were involved in an eligible crash, you may submit a Request for Data Review (RDR) with the required police accident report and other supporting documents, photos, or videos through the Agency’s DataQs system.

Crashes determined to be Not Preventable through the CPDP are removed from the calculation of the Crash Indicator Behavior Analysis Safety Improvement Category (BASIC) in FMCSA’s SMS, but are still listed on the website. Not Preventable determinations are also noted in FMCSA’s Pre-employment Screening Program.

Crash Eligibility

FMCSA expanded the CPDP on December 1, 2024. Crashes on or after this date follow the eligibility list on this page, while those prior to December 1, 2024, will be reviewed under the previous standards. FMCSA cannot review crashes older than 5 years. For eligibility requirements for crashes occurring prior to December 1, 2024, click here.
