Motorway incident

[tobeee]

My friend had an accident on the motorway, and we'd be interested to know how the law stands in the circumstances:

He was in stationary/slow moving traffic in third lane, and indicated left to move into middle lane. Eventually a lorry signalled him access, but as he moved across, a motorbike ran into him, hitting the front wing. Both stopped to exchange details, and no injuries, so that's good.

So, who's wrong? Maybe both of them - driver for not looking carefully enough, and biker for jumping traffic inbetween lanes. Please can someone give a balanced legal viewpoint.

Not a wheelie, but a pretty good stoppie by all accounts!

Thanks for all your thoughts.

The issue I was most interested in was the biker creating a fourth lane. I'm not anti-biker (ride trials myself) but it's probably a common thing for people to be surprised by a bike zipping between lanes on a motorway. Must be a clear-cut answer as to whether the biker is acting illegally or merely endangering himself by riding between lanes...

Anyway, this seems to have opened a can of worms, so I hope nobody's been upset by anyone else's comments.
