Following a truck accident, there are several things you need to do to safeguard your future claim against the negligent party. First and foremost, you must get medical treatment for your truck accident injury. Those who are involved in a truck accident often suffer severe injuries, including traumatic brain injuries, spinal cord injuries, amputations, internal injuries, and disfigurement from burns. Even if by some miracle you think you are not that badly hurt, you should still be checked out by a medical professional.
