Withdrawal of Proposed Enhancements to the Safety Measurement System

Notice.

On June 29, 2015 and October 5, 2016, FMCSA proposed enhancements to the Agency's Safety Measurement System (SMS) and published a preview version of the changes. However, the Fixing America's Surface Transportation Act (FAST Act) required the National Research Council of the National Academy of Sciences (NAS) to conduct a study of FMCSA's Compliance, Safety, Accountability (CSA) program and the Safety Measurement System (SMS). NAS published their report titled, ``Improving Motor Carrier Safety Measurement'' on June 27, 2017. This notice announces that FMCSA will not complete the enhancements previously proposed and the preview is removed from the SMS website.
