A Georgia Department of Transportation crew was on the way to put up fog-warning signs just before Wednesday's fatal crash, the state agency says.
Drivers had complained of dense fog along I-16 Wednesday morning.
Cissy McNure, spokeswoman for GDOT's District 2, said Laurens County 911 had requested crews place metal signs on the interstate warning motorists of the dense fog.

Department of Transportation crew was alerted and was en route with warning signs at the time of the massive I-16 crash.
McNure said, "Usually the GSP (Georgia State Patrol) makes the decision to request a display of warning signs. GSP usually makes such a call."
By phone from her office in Tennille, McNure said, "DOT did not wait for a call from the State Patrol. Following the 911 call we began activating and didn't discuss whether the highway should be closed. "
The time lapse between the initial call from 911 to the first accident was 28 minutes, McNure said.
McNure acknowledged that state guidelines for smoke and fog along roads and highways focus on primarily on smoke and fires, wildfires and controlled burns.
The Georgia Forestry Commission would typically notify the State Patrol of dense-visibility driving conditions, with the GSP calling DOT.
