In Virginia, federal officials have shut down a Springfield bus company after finding what they say are multiple safety violations.
The bus company, Advanced Ventures, operates a small fleet of motor coaches and minibuses throughout the region, which provide charter services. On Wednesday, Advanced Ventures was ordered to stop all operations.
Investigators say the charter bus company falsified annual vehicle inspection documents, and their inspections of five buses found 39 safety violations, with two vehicles were immediately removed from service.
Investigators also say owners of the company repeatedly allowed drivers behind the wheel before receiving results of pre-employment drug and alcohol tests, as required by federal regulations.
The shutdown was part of the Federal Motor Carrier Safety Administration's intensified investigation known as "Operation Quick Strike," begun in April. That month, officials shut down the Washington DC Party Shuttle, which ran tours in D.C. and Alexandria.
