If you are a learner drive and want to turn left at a roundabout, approach this challenge as if you were going to go straight on or turn right. In other words, get into the outer lane so that you can cut across any cars planning to go straight on. If there is a traffic jam in the exit lane you wish to take and there are two cars stationery on the roundabout waiting for the jam to clear, check whether they have left a gap for traffic entering the roundabout from their right. If so, overtake these stationery cars and plug the gap, so making it impossible for the traffic to flow.
