A. 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.
B. 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 centerline thereof and by passing to the right of such centerline where it enters the intersection, and after entering the intersection the left turn shall be made so as to leave the intersection in the lane nearest to the right of the centerline of the roadway being entered. Whenever practicable, the left turn shall be made in that portion of the intersection of the left of the center of the intersection.
C. 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.
D. When traffic control devices are placed at an intersection indicating the course to be traveled by vehicles turning thereat, no driver of a vehicle shall disobey the direction of such indications.

The making of such turns may be prohibited between certain hours of any day and permitted at other hours, in which event the same shall be plainly indicated on signs which may be removed when such turns are unrestricted.
G. Whenever such authorized signs are erected indicating that no right or left turn is permitted, no driver of a vehicle shall disobey the directions of any such sign. (Prior code title 46, art. 11 § 195)
