This article is an update to the February 9, 2012 comprehensive review of the FMCSA’s CSA program written by Walt Metz, entitled “CSA and Motor Carrier Safety Ratings: The Past, Present and Future” published in JD Supra. CSA continues to be a work in progress and recent changes make it no less controversial. Developments that have occurred since the first article was published include a delay by the FMCSA in implementing a system for assessing carrier responsibility for reportable crashes, changes or “enhancements” to the Safety Measurement System (“SMS”), and a further delays in implementing the FMCSA’s plan to use SMS data in the making of Safety Fitness Determinations for carriers. These three issues are addressed in the article update.
