(c) after entering the intersection, turn the vehicle to the left so that it leaves the intersection to the right of the marked centre line of the roadway being entered, or if there is no marked centre line then to the right of the centre line of the roadway being entered, and,

(d) when practicable, turn the vehicle in the portion of the intersection to the left of the centre of the intersection.

(3) When the driver of a vehicle intends to turn the vehicle left at an intersection where traffic is restricted to one direction on one or more of the highways, the driver must cause the vehicle to approach the intersection in the extreme left hand lane available to traffic moving in the direction of travel of the vehicle, and after entering the intersection turn the vehicle to the left so as to leave the intersection as nearly as practicable in the left hand lane available to traffic moving in the direction of travel of the vehicle on the highway being entered.
