How does the CEMAC Highway Code require a left turn to be made from a two-way street into another two-way street?

1. Move as close as possible to the centre line beforehand, let oncoming traffic pass, then enter the new road on its right-hand side
2. Move as close as possible to the right-hand kerb beforehand and swing across in one wide movement
3. Cut the corner and enter the new road on its left-hand side before merging right
4. Turn without slowing, because a vehicle turning left has priority over oncoming traffic
