FMCSA has extended the public comment period for its proposed rule on safety fitness determinations for motor carriers. The comment extension is a result of stakeholder requests to FMCSA. The deadline for the submission of initial comments is now May 23, 2016. Reply comments will be due on or before June 23, 2016. Under the proposal, it would replace the current three-tier federal rating system of "satisfactory-conditional-unsatisfactory," which has been in place since 1982, with a single determination of "unfit." A carrier that is determined to be unfit would be required to either improve its operations or cease operations (Truckinginfo).
