REMARKS / The Federal Motor Carrier Safety Administration has made numerous enforcement determinations in the past few weeks shutting down motor carriers in both passenger and freight. COMMENT: This probably indicates something about enforcement priorities – but candidly I do not know more about the detail of such changes.

See here, here, here, and here.

Also, U.S. DOT Secretary LaHood and FMCSA Administrator Ferro met recently  (April 5) with representatives of the passenger motor carrier industry to address safety issues.
