PHOTO: A car overturned and caught fire in a multi-vehicle crash on I-85 in Gwinnett County late Thursday afternoon, snarling traffic for hours. The Georgia State Patrol said they responded to a four-vehicle crash on the southbound lanes of the interstate at Lawrenceville-Suwanee Road around 5:30 p.m. Troopers said Gwinnett fire crews were already on the scene when they arrived, extinguishing a burning, overturned car. Georgia State Patrol said the 16-year-old driver of the overturned car was able to escape from his vehicle without injury. Troopers said the 16-year-old is suspected of having caused the crash. The other three vehicles involved in the crash were found on the right shoulder. Two of those vehicles had “sustained disabling damage.”
