Im not a confident driver. Should I just drive in the outer lane?
No. You must drive in the proper lane. If you are turning left, enter from the left lane and travel in the inner lane of the roundabout. If you are turning right, enter from the right lane and travel in the outer lane of the roundabout. If you are driving straight through the roundabout, you may enter from either the left lane or the right lane. Do not change lanes within the roundabout.
