MISSOULA, Mont. -

The American Bus Association may drop Rimrock Stages membership; this comes after the United States Department of Transportation shut the bus line down over safety concerns.

NBC Montana headed to the bus stop Sunday afternoon where we found the station empty and locked. 

A hand-written sign on the door reads ‘all east and north schedules have been cancelled until further notice – including but not limited to Livingston, Kalispell, Butte, Bozeman, Billings, Helena, Whitefish, Great Falls, etc.’

Another sign simply says ‘hours are 7:30 a.m. - 11:30 a.m. and 9:30 p.m. - 11:00 p.m.’

The bus line was shut down after failing safety and maintenance checks.  The out-of-service order gave the company a short window of time to get their passengers to their final destination before they had to pull their busses off the road.

NBC Montana spoke to Dan Ronan, a spokesperson for the American Bus Association, says the association supports the Department of Transportation’s decision and they too will look to drop Rimrock Stages.

"The American Bus Association has been very supportive of the Department of Transportation to get unsafe bus companies off the road,” said Ronan.  “In the compliance review, the FMCSA found enough problems to issue this order."

Rimrock Stages has been in business for more than 30 years. 

On the company’s website a memo reads: “Effective 3/22/2013 all Rimrock Stages service is indefinitely suspended until further notice.
