How should a driver generally make a left turn at a junction?

1. Turn from the right-hand kerb as the default method on every road
2. Stop in the middle of the junction with hazard lights until oncoming traffic disappears
3. Swing wide into the oncoming lanes of the road being entered
4. Take the shortest path that still leaves the vehicle in the correct half of the new road, giving way to oncoming traffic going straight or turning right
