§ 31-5-214 — Required position and method of turning at intersections

(a) The driver of a vehicle intending to turn shall do so
as follows:
(i) Right turns: Both the approach for a right turn
and a right turn shall be made as close as practicable to the
right-hand curb or edge of the roadway;
(ii) Left turns: 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 vehicle. Whenever practicable the left turn shall
be made to the left of the center of the intersection and so as
to leave the intersection or other location in the extreme
left-hand lane lawfully available to traffic moving in the same
direction as the vehicle on the roadway being entered;
(iii) Two-way left turn lanes: Where a special lane
for making left turns by drivers proceeding in opposite
directions has been indicated by official traffic-control
devices:
(A) A left turn shall not be made from any other
lane;
(B) A vehicle shall not be driven in the lane
except when preparing for making a left turn from or onto the
roadway or when preparing for a U-turn when otherwise permitted
by law.
(b) The highway department and local authorities in their
respective jurisdictions may cause official traffic-control
devices to be placed and thereby require and direct that a
different course from that specified in this section be traveled
by turning vehicles and when the devices are so placed no driver
shall turn a vehicle other than as directed and required by the
devices.
