To start this manouevre pull past the junction and stop with a good gap away from the kerb. Using your mirror get yourself parallel to the kerb with the corner in clear view. As you start to reverse make sure you do full observations including your blind spots on both sides. People will always walk passed the back of your car regardless of reverse lights or not and cars will continue to drive up to the junction.

If anyone gets near the car STOP! Keep reversing until the curve of the corner is about to disappear of the bottom of the mirror as shown opposite. Now you need to decide how much to turn. Its not an exact science. See opposite for my personal experience on this subject.

Continue to follow the kerb using your mirror whilst keeping those observations all around you. If anyone approaches the car STOP! Once you have completed the curve and your door handles appear parallel to the kerb like the 1st photo above straighten your wheels and reverse for about 2 car lengths in a straight line. This will allow any cars coming up from behind to go around you and get back onto the correct side of the road in time to take the turn.
