An investigation is still under way, trying to determine the exact cause of a Dec. 30 bus crash on an icy stretch of I-84 that killed nine and injured 38 more. But federal officials didn't wait for the results of the probe to order the Mi Joo Tour and Travel Company—the Vancouver, B.C., owners of the bus—to stop touring in the United States.
The bus crashed through a guard rail and plunged 200 feet down an eastern Oregon embankment, throwing some passengers through broken windows of the bus.
The U.S. Department of Transportation on Tuesday revoked Mi Joo Tour's authority to provide passenger service in the United States. The agency said in its order that the company allowed its driver to remain behind the wheel after he had been on duty for 92 hours during an eight-day stretch—far more than the 70-hour limit.
The Associated Press reports that Transportation Secretary Ray LaHood added that his agency would move quickly to shut down any bus company that doesn't act safely.
