DOT: Unsafe buses removed from roads before holiday weekend

DOT said it also had launched 38 compliance reviews of commercial bus rating, which are used to determine a company's safety rating. 

"The public deserves safe passenger bus transportation every ride,” Federal Motor Carrier Safety Administration chief Anne Ferro said in a statement. "FMCSA and its law enforcement partners will not rest until we weed out every unsafe passenger carrier and driver."

The department has proposed requiring bus drivers to get learner's permits before they can obtain commercial driver's licenses.
