Charles Caldwell, 44, is charged with felony serious injury by vehicle and DWI.
Meanwhile, Officer Teresa Gilliam is listed in fair condition at Duke University Medical Center.
The 15-year veteran had just pulled over another driver near the Cole Mill exit when eyewitnesses saw the tractor trailer Caldwell was driving swerve and slam into Gilliam's unmarked cruiser. The impact forced the squad car into the other stopped vehicle.
Warrants revealed Gilliam suffered two broken ribs, a brain injury and injuries to her spine and back.
Neither the stopped driver nor Caldwell, who both went to the hospital, suffered any major injuries.
According to court records obtained by ABC11, Caldwell was seen weaving all of the road before the crash. He was going 70 in a 60 mile per hour zone and failed to move over as he was approaching Gilliam's stopped patrol car.
Officers on the scene, who performed blood tests, also noted that Caldwell's eyes were droopy and his speech was slurred.
Caldwell is now out of jail on a $100,000 bond.
