The other party is claiming that I came accross into his lane. But the lane merges into one after the junction, and I was half a car ahead of him, as the point of impact was under my drivers door to the back. Unfortunatley there were no witnesses, photos of the accident were given but just of the damage, not where the cars were positioned on impact. He was stationary at the lights on the right, I was approaching the lights, they turned green, I continued and he took off and went into me. This was just after the traffic lights in the box junction, before you merge into one lane after the junction. But as you say how can I prove this, such is life, should I just bear the loss?
