One of the methods that insurance companies use to investigate car accidents is a recorded statement. As the words suggest, the conversation is usually recorded over the telephone or sometimes the car accident insurance company will attempt to go to your home for an in-person statement with you.
In a recorded statement, you will probably be asked questions about the accident, your injuries, private medical information, date of birth, and even your social security number. Remember, the insurance company is not looking out for your best interest and anything you say will likely be used against you later on. This is why it is so important that you have legal representation.
