Take a dominant position on right turns, you have right of way to things behind you. I've had people try and undertake/overtake on junctions and I've seen them do it to other people, this is incredibly dangerous as especially at junctions another vehicle may block the view of you out to and they could set off whilst your left stationary and plough into you. Occasionally on right turns you'll get a tw*t overtake you so be aware of that .
