BARTOW COUNTY, Ga. -- First responders in Bartow County say an accident sent a semi-truck careening through several trees. Now the driver has been flown to an Atlanta trauma center for emergency treatment.

Crews believe the unconscious victim was thrown from the truck as it left the pavement and slammed into trees along I-75 - not far from the Canton Highway exit.

Arriving paramedics found the driver and immediately began emergency treatment. They also called in a helicopter to get him to Grady Memorial Hospital. So far, however, no one is sure what caused the victim to leave the road.
