Mistake #4 - Giving a recorded statement to the driver's insurance company.
The at-fault driver's insurance company will almost always ask you for a recorded statement. Don't do it! The statement will be used by the company to look for any "holes" in your story. There are always minor discrepancies when a person is asked to recount a traumatic incident. The carrier knows this and will use these minor discrepancies either to reject your claim entirely or to minimize the amount of compensation it has to pay out. The only reason to give a statement is to help the insurance company. Sometimes it may be beneficial to give a statement to the company, but you should always consult with an attorney first to determine if that situation applies to your case.
