Georgia Code Title 40. Motor Vehicles and Traffic § 40-6-120

(2) Left turn. (A) As used in this paragraph, the term “extreme left-hand lane” means the lane furthest to the left that is lawfully available to traffic moving in the same direction as the turning vehicle. In the event of multiple lanes, the second extreme left-hand lane shall be the lane to the right of the extreme left-hand lane that is lawfully available to traffic moving in the same direction as the turning vehicle. The third extreme left-hand lane shall be the lane to the right of the second extreme left-hand lane and so forth.

(B) The driver of a vehicle intending to turn left shall approach the turn in the extreme left-hand lane lawfully available to traffic moving in the direction of travel of the turning vehicle. Whenever practicable, the left turn shall be made to the left of the center of the intersection and so as to exit the intersection or other location in the extreme left-hand lane lawfully available to traffic moving in the same direction as the turning vehicle on the roadway being entered.

(C) In the event of multiple left turn lanes, the driver of a vehicle turning left shall exit the intersection in the same relative travel lane as the vehicle entered the intersection. If the vehicle is in the second extreme left-hand lane entering the intersection, the vehicle shall exit the intersection in the second extreme left-hand lane. Where there are multiple lanes of travel in the same direction safe for travel, a vehicle shall not be permitted to make a lane change once the intersection has been entered.
