      (1)   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)   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.

      (4)   Markers, buttons or signs may 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 such markers, buttons or signs are so placed, no operator of a vehicle shall turn such vehicle at an intersection other than as directed and required by such markers, buttons or signs.
