And investigators are unsure of the exact time of the crash, Vincent said. First responders arrived at the scene after another driver noticed the damaged guardrail and vehicle and called 911.

A DeKalb County police officer who responded to the incident said the engine was no longer in the car. It was laying next to the vehicle, according to the officer.

One right lane of U.S. 78 is blocked while investigators are at the scene, according to the WSB 24-hour Traffic Center.
