On January 21, 2016 (81 FR 3561), the Federal Motor Carrier Safety Administration (FMCSA) published a notice of proposed rulemaking (NPRM) in the federal register to amend the Federal Motor Carrier Safety Regulations (FMCSRs) 49 CFR Parts 350, 365, 385, 386, 387, and 395 to revise the current methodology for issuance of a safety fitness determination (SFD) for motor carriers. The proposed new methodologies would determine when a motor carrier is not fit to operate commercial motor vehicles (CMVs) in or affecting interstate commerce based on the carrier’s on-road safety data in relation to five of FMCSA’s seven Behavior Analysis and Safety Improvement Categories (BASICs); an investigation; or a combination of onroad safety data and investigation information. The intended effect of this action is to more effectively use FMCSA data and resources to identify unfit motor carriers and to remove them from the Nation’s roadways. FMCSA will be accepting both initial comments and reply comments in response to this NPRM. Please send your initial comments on or before March 21, 2016 and reply comments on or before April 20, 2016.
