Changing lanes in a circle

Question

I had a situation in a circle with two lanes. There are no signs in the lanes around the circle that indicate if you can turn left from that lane. Can you turn left from the inside lane of such a circle or must you go to the left/outside lane first before exiting the circle? Is there a basic rule if there is no road signs that indicate where you may or may not turn, or to go around the circle?

Answer

You must move to the outside lane to exit the circle (inside lane for continuing around the circle). Indicate your intention and move over when safe to do so. There is no basic rule apart from keep left and signal clearly when changing direction.
