Move right, towards the centre of the lane (see Take the lane) before reaching the intersection.
If the road you are on has more than one lane each way through the intersection, get into the correct lane before the intersection (see Using hand signals correctly).
If traffic is queuing at the intersection, you may be able to move carefully to the front of the queue. See:
Signal if you are turning left or right (see Signalling).
Follow the traffic lights, signs or give way rules controlling the intersection you are at.
