ATRI Releases Study on Impact of Non-Preventable Crashes and their role on CSA

The American Transportation Research Institute (ATRI) this week releases its latest research study examining the Compliance, Safety, Accountability (CSA) initiative. Specifically, this research focused on “Assessing the Impact of Non-Preventable Crashes on CSA Scores.” In this analysis, ATRI investigated the impact that excluding non-preventable crashes would have on motor carrier CSA Crash Indicator BASIC measures. The analysis used carrier crash records, mapped to the FMCSA's Motor Carrier Management Information System (MCMIS) database, to identify a small and non-controversial subset of nonpreventable crashes with the following causes:

  • Animal collision
  • Other vehicle hits legally parked truck
  • Other vehicle ran a stop light / sign and hit a truck 
  • The driver of the other vehicle was DUI 
  • Truck-assisted suicide

The ATRI analysis then removed these crashes and "recalculated" the Crash Indicator BASIC measure. Among the more than one dozen carriers in ATRI's analysis, the Crash Indicator BASIC decreased nearly 15 percent once the non-preventable crash subset was removed.

Beyond CSA BASIC score impacts, these non-preventable crashes exact a toll on motor carriers and commercial drivers. ATRI's analysis documents these impacts in detail, including real-world crash examples collected from the industry. ATRI also estimates non-preventable crash costs that exceed $68 million for the 15 carriers in the analysis.
