The truck accident claims process will usually begin with a thorough investigation to determine which parties (the trucking company, freight company, etc.) may bear liability for the accident. The next step involves making a formal claim for compensation against those companies and their insurers. Their trucking company insurers will conduct their own investigation.
Usually, your attorney and the other parties will begin negotiating a compensation amount acceptable to both parties. If the parties cannot reach a negotiated settlement, the case will head to a trial in court.
