What is the correct procedure for turning left or making a U-turn (third or fourth exit) at a multi-lane roundabout?

1. Approach in the far right lane with no signal, drive all the way around the outer perimeter, and exit
2. Approach in the left lane signaling left, circulate in the inner lane, signal right after passing the exit before the target, and exit into the left/middle lane
3. Approach in the right lane signaling left, cut across the middle island, and stop in the center
4. Enter from any lane without signaling and brake to a stop in the inner roundabout lane
