There's not enough detail to be sure what happened, and, with the best will in the world, we only have your side of the story. However, if you were in a specifically marked lane and he tried to move into that lane without checking it was safe to do so then I can't imagine how you would be in any way at fault.
That is exactly the way I see it, but his story appears to be that he was in the marked lane and I tried to move into his lane. There is no suggestion as to why I would have possibly wanted to do this, and I still do not see how they can say the damage to the cars is more consistent with his account than mine. The relative postions of the cars means I was probably in his blind spot, but he was not in my blind spot, which is why I saw him and attempted to brake. The whole whiplash side of things is completely ridiculous.
I agree that in the absence of an independent witness, it is his word against mine, so it may not be possible for someone independent to decide. But what they are saying is a decision has been made, and that his account is more plausible. That is what I do not understand, and what is making me so angry.
These posts do raise one or two questions though.
If it were 50/50, does that mean my premium will go up just as much?
I am now wondering what the protected no claims actually means. I was told it meant you can have two at fault claims in five years without the NCD being affected. However, one of the post here mentions they will just put up my basic premium anyway. How much does that go up by? If it is a minor increase, that is one thing, but if the premium more than doubles or something stupid like that, then that is pretty serious stuff.
Is the protected NCD only valid if you stay with the same underwriter? Although I am insured with NU, it is via Kwik-fit as the broker. Surely the protected no claims will be valid if my next policy is via the same broker, even if it is not recognised by a completely separate insurance company? I really do not want to give NU any more business. No wonder they are having to change their name to get any more business.
Sorry to ask all these stupid questions, but in 25 years of driving, and several minor accidents, this is the first time I have ever been considered liable.
