It's a bit harder to buy a cheap ticket on a bus line on the East Coast. The federal government has shut down 26 bus companies, citing safety concerns.

FOX News Radio's Rich Johnson reports from Washington:

The Transportation Department has shut down 26 bus companies operating along Interstate 95 between New York and Florida, calling those companies 'imminent hazards to public safety'.

Violations include: Using unlicensed and unqualified drivers, using un-inspected buses and breaking work schedule and rest requirements.

Regulating small bus companies has been tough because many, once they're shut down, re-emerge under new names with the same people and the same equipment -- what the industry calls "ghost buses".

Editor's Note: The bus companies carry about 1,800 passengers a day.
