PHILADELPHIA, PA - MARCH 30: A man walks by discount buses to New York City on March 30, 2011 in Philadelphia, Pennsylvania. After a series of recent accidents, one of which killed 15 and injured more than a dozen others on March 12 on the Westchester County-Bronx border, discount bus services have come under intense scrutiny. The popular bus services take passengers on routes to Boston, Washington DC and numerous southern cities for discounted rates. The Department of Transportation (DOT) said it inspected 164 buses following the crash and found violations in 41 cases. A Senate subcommittee will meet this afternoon to consider whether new protections such as seat belts or mandatory driver training are needed in federal law.
