I approached a junction with a lorry waiting at it. I thought the lorry was going right due to its positioning on the road. I know they have to go wide but this guy was literally in the middle of the road. He wasn’t indicating. I’m going left so I pull up on the left side of the junction where I am now side by side with the lorry. I am stationary and checking left and right for a gap to go. The lorry then decides to go left and crashes into the side of my car. I must have been in his blind spot for him not to see us. That’s my car written off but at least we are all ok. Am I at fault?
