I was taught to make a lateral move towards the centre of the road which approaching a junction, which draws attention and is more visible than taking a constant line. The other thing is to watch the rotation of front wheels - a vehicle creeping isn’t always obvious as your perspective changes on approach but wheels rotating (or not) isn’t affected.
I tend to do the lateral move towards the centre of the road if possible, but on my usual ride in into London a wiggle is often easier with the road space.
