Things aren't looking so good for the super-cheap bus market. Last week, the Feds shut down Chinatown bus company Fung Wah—and yesterday, they revoked the operating license of another Chinatown bus company, Ming An, after finding they employed dangerous, unlicensed drivers.

After an earlier inspection, the DOT's Federal Motor Carrier Safety Administration (FMCSA) found Ming An drivers were frequently ticketed for speeding, did not undergo necessary drug-and-alcohol testing, didn't keep logbooks and some were unlicensed. The FMCSA also found some buses in states of disrepair, and noted the company failed to properly maintain them , leading them to declare Ming An, which primarily ran routes to Southern cities like Virginia Beach and Tampa, "imminent hazard to public safety" and pull their license.

"We are committed to removing unsafe bus and truck companies from our highways and roads," said Transportation Secretary Ray LaHood in a statement. "We will not let up and we will not slow down. Companies that ignore our safety regulations will not be tolerated." Guess you're going to have to spend real money to get to Charleston now, huh.
