It is the responsibility of the truck accident lawyer to help you prove that the truck driver or trucking company was at fault for your PA or NJ truck accident. Depending on when the truck accident lawyer is retained, he or she may send an investigator to the scene of the truck accident to gather as much information as possible. The trucking companies also send their representatives to the scene of a trucking accident in order to minimize the liability of the trucking company and the truck driver. Sometimes trucking company representatives will distract investigating police officers and skew the evidence. The local police department or the State Police will issue an accident report. The truck accident attorney should then review the report, speak to the investigating police officers, and if necessary, hire a truck accident re-constructionist to reproduce the truck accident. The attorney will also obtain the truck’s computer records and analyze those records. In addition to any eyewitness testimony, all of the results of the investigation will then be used to help prove that the truck driver or trucking company caused the accident.
