Withdrawal of Proposed Improvements to the Motor Carrier Safety Status Measurement System (SafeStat) and Implementation of a New Carrier Safety Measurement System (CSMS)

Notice; request for comments.
The FMCSA announces that it will replace its Motor Carrier Safety Status Measurement System (SafeStat) with an improved Carrier Safety Measurement System (CSMS) on November 30, 2010. The CSMS has been developed and tested as part of the Agency's Comprehensive Safety Analysis 2010 (CSA 2010) initiative. Therefore, FMCSA is withdrawing the notice of proposed improvements to SafeStat that was published for public comment on May 3, 2006. SafeStat is an automated algorithm currently used by FMCSA to identify high-risk and other motor carriers for on-site compliance reviews. By implementing the new CSMS algorithm, FMCSA will be able to better identify high-risk motor carriers, make more efficient and effective the Agency's and its State partners' allocation of compliance and enforcement resources and provide the motor carrier industry and other safety stakeholders with more comprehensive, informative, and regularly updated safety performance data. From April 12, 2010 to November 30, 2010, FMCSA will provide individual motor carriers with a preview of their performance data at This preview in advance of full implementation on November 30, 2010, will improve safety by effecting early compliance and providing opportunities for motor carriers to become better educated on the new CSMS.
