How should a driver position their vehicle on a two-way street when preparing to make a left turn at an upcoming intersection?

1. Position the vehicle near the centre line of the roadway without crossing it, signal left, and yield to oncoming traffic
2. Position the vehicle on the far right shoulder and make the turn abruptly across both lanes
3. Move entirely into the oncoming traffic lane 50 metres before the junction
4. Keep to the extreme right curb and turn without using turn signals
