There is currently a big deal with riders being found 50% liable even in cases just like this.
To be honest Wes i'm quite sure thats bullshit so don't worry, I mean how the fuck can you be held even 1% liable let alone 50% when you were on the main road and it was down to her to check the road was clear before she pulled out!
Tis a shame about the bike tho mate, glad your ok chap!
