As many as six motorists were charged with drunk driving after a seven car pileup on a stretch of Interstate in Georgia early Sunday morning.

A pedestrian walked onto I-75 near the Hartsfield-Jackson Atlanta International Airport at 3 a.m., and was struck by a vehicle, setting off a chain reaction, according to Daniella Rosa, a spokesman for the Clayton County Police.

"Luckily, nobody was killed," Rosa told reporters. However, the pedestrian and a few others were hurt in the sequence of crashes.

Officers responding to the scene initially charged five of the drivers with drunk driving, including William Scott Kirk II, Najm Martinez, Joseph Daise, Tawan Hayes, and Joshua Noble. The sixth drunk driver, transported to the hospital, will be charged once he is released. Police say one of the drivers "blew" a 0.14 percent blood-alcohol content (BAC) on the breathalyzer test, which was well over the 0.08 percent legal limit for driving. Another driver blew a BAC lower than the legal limit but was charged after police determined that alcohol impairment played a role in his reaction to events on the roadway.

Police also plan to charge the pedestrian with obstructing traffic. However, that person is critically injured, according to the Atlanta Journal-Constitution.

The National Highway Traffic Safety Administration says drunk driving killed 10,000 Americans in 2010 and costs the U.S. economy $37 billion per year.
