When taking an exit to the right (e.g. third exit) at a multi-lane roundabout, what is the correct procedure?

1. Approach in the left lane and signal left continuously
2. Approach in the center without signaling and take whichever lane is empty
3. Approach in the right-hand lane indicating right, maintain position around the island, then signal left after passing the exit prior to your intended exit
4. Sound horn continuously while circling in the outer left lane
