I have just had an accident in my car?

it is very hard to understand what happened in the accident. your description has to be detailed to the point someone reading it can draw a picture of the accident scene. your insurance company is going to get recorded statements from all parties involved, obtain the police report, and possibly do a scene investigation. your insurance company will at that point make a liability decision. whether you feel you are at fault or not does not matter. the facts of the loss is what matters and that is what your insurance company is going to based their decision on. not much you can do but let your insurance company complete the necessary steps and settle the claim. just worry about getting your vehicle repairs.
