A left turn from a one-way street into a two-way street shall be made by passing to the right of the centerline of the street being entered upon leaving the intersection.
(2) 
Approach for a left turn from a one-way street into a two-way street shall be made as near as practical to the left-hand curb or roadway edge of the one-way street.
(3) 
When markers, buttons or signs are placed within or adjacent to intersections, thereby requiring and directing that a different course from that specified in this section be traveled by vehicles turning at an intersection, no driver of a vehicle shall turn a vehicle at an intersection other than as directed and required by such markers, buttons or signs.
