How do I proceed with a personal injury claim?

I recommend that you take advantage of a free consultation offered by an attorney located in your area. It is very difficult to answer these types of questions via email. Do some research on who is a good attorney in your area and most offer no obligation consultations which can get you started on what you need to do with an injury claim from a car accident.   You may need to call more than one attorney but speaking with attorney should be the first step if you have not been through  the insurance claims process before with a personal injury.
