§47-11-601.
   
   The driver of a vehicle intending to turn at an intersection shall do
   so as follows:
   
   1. 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.
   
   2. Left turns on two-way roadways. At any intersection where traffic
   is permitted to move in both directions on each roadway entering the
   intersection, an approach for a left turn shall be made in that
   portion of the right half of the roadway nearest the center line
   thereof and by passing to the right of such center line where it
   enters the intersection and after entering the intersection the left
   turn shall be made so as to leave the intersection to the right of the
   center line of the roadway being entered. Whenever practicable the
   left turn shall be made in that portion of the intersection to the
   left of the center of the intersection.
   
   3. Left turns on other than two-way roadways. At any intersection
   where traffic is restricted to one direction on one or more of the
   roadways, the driver of a vehicle intending to turn left at any such
   intersection shall approach the intersection in the extreme left-hand
   lane lawfully available to traffic moving in the direction of travel
   of such vehicle and after entering the intersection the left turn
   shall be made so as to leave the intersection, as nearly as
   practicable, in the left-hand lane lawfully available to traffic
   moving in such direction upon the roadway being entered.
   
   4. Local authorities in their respective jurisdictions may cause
   markers, buttons or signs to be placed within or adjacent to
   intersections and thereby require and direct that a different course
   from that specified in this section be traveled by vehicles turning at
   an intersection, and when markers, buttons or signs are so placed no
   driver of a vehicle shall turn a vehicle at an intersection other than
   as directed and required by such markers, buttons or signs.
