Tragic Baltimore Beltway Crash Claims Lives of 6 Construction Workers.

Six construction workers were killed in a traffic accident in Baltimore County, Maryland, when a black car collided with a white car on the Beltway, sending the black car over the median and into the middle of a work zone. The cause of the accident is still under investigation, but it appears the black car may have been changing lanes while the white car was in its blind spot and "speeding aggressively." The National Transportation Safety Board is investigating the crash, including an analysis of the safety of highway construction zones.
