The Answer is Yes.
The insurance company is in this business and know way more than you do about auto injuries. The goal of the adjuster is to protect the insurance company that they work for. This put you at a big disadvantage. I recommend consulting with a (PI) personal injury attorney to get some guidance and learn your rights. At my office I prefer to work with an attorney that I know and trust. Please come to my office for a consultion and I will help you find the right attorney for you.
