Trucks move out at junctions to let people out then get undertaken by impatient drivers.
It's your life, just don't ruin someone elses because you need to drive like a tw*t.
Good point actually, yesterday I decided to move out into the middle lane as a busy slip road up ahead, modified Saxo driver decides to try and undertake me.

Fast lane and middle lane had been clear for some time should he have decided to overtake before.
I just put my foot down a bit and forced him to slow down then come into the middle lane.
