Authorities: 3 dead in fiery highway crash in Ga.

MONTROSE, Ga. -- More than two dozen vehicles collided in a fiery pileup on a foggy Georgia interstate on Wednesday morning, killing at least three people and leaving several others hurt, officials said.

Laurens County EMS director Terry Cobb, who was at the scene on Interstate 16 in central Georgia, told The Associated Press at least six vehicles were still on fire when crews arrived. Emergency officials encountered fog on the way to the crash site, though it was not immediately known if that was a factor in the wreck, Cobb said.

"Once we got there, the fog was kind of lifted at the scene," he said.

A total of 27 vehicles were involved in four separate accidents around 8:10 a.m., the Georgia State Patrol said in a news release.

They included six commercial vehicles and an empty petroleum tanker truck, which ruptured and caught fire, the patrol said.

Cobb said Wednesday morning that 12 people were taken to hospitals, most with what appeared to be minor injuries. However, the state patrol said later in the day that nine people were hurt. The discrepancy in the number of injuries could not immediately be resolved.

It wasn't known what caused the wrecks, but the area was under a dense fog advisory at the time, said Laura Belanger, a meteorologist at the National Weather Service in Peachtree City. In some areas, visibility was only a quarter-mile or less, Belanger said.

The pileup happened near Montrose, about 40 miles southeast of Macon. It shut down a roughly seven-mile stretch of the highway that is a major artery between Savannah and Macon, forcing cars to be detoured around the area.

Video from WMAZ-TV in Macon showed flames and dark, heavy smoke along the interstate.
