Any action which causes another driver to brake or take avoiding measures is probably a wrong one.
As a frequent joiner of a dual carriageway, I am regularly 'blocked' from joining it by cars in the nearside lane who won't move over when the outside lane is perfectly clear. I guess it's their right....
Thats an interesting issue in its won right.The rules are quite clear - you leave the slip road and enter the dual carriageway when its clear to do so, and you cant just force a car in the inside lane to move to the outside. There never used to be a problem with this but in recent years its more and more the case that cars just force their way in from the slip road as if its their right to do so.
