It happened December 21, around 1:30 p.m., at Exit 293 on Interstate 75.

A GSP spokesperson says the 1998 Ford Expedition, driven by 29-year-old Maria Tabuena from Calhoun, Georgia, was hit on the left side, as the tractor trailer changed lanes traveling north.

Witnesses described the semi as a late 90s "long-nose" Peterbilt, maroon in color, and pulling a silver trailer with damage to the right side.
