The U.S. Department of Transportation’s Federal Motor Carrier Safety Administration (FMCSA) has declared a Mitchell, South Dakota-based trucking company, Lonnie Roth, and separately its owner, Lonnie Roth, as a commercial driver, to be imminent hazards to public safety and ordered the company and the driver to immediately cease all interstate and intrastate commercial operations.

The National Transportation Safety Board (NTSB) has recommended audits of the Federal Motor Carrier Safety Administration’s oversight processes in light of several deadly crashes that the NTSB investigated. The NTSB said the findings from these investigations raise serious questions about the oversight of motor carrier operations.
