An auto wreck lawyer protects accident victims and ensures their rights in a court of law. Personal injury auto accidents typically fall into three main categories. Negligence includes inattentive drivers, poor road maintenance, and personal cargo exposure. Product liability determines the fault of tires, air bags, child safety seats, and other defective parts. Vehicular assault is the third category and includes serious injury and death charges. An auto wreck lawyer will also have the knowledge to represent other vehicles such as motorcycles, boats, and trucks in accident cases. Once the cause of the accident is determined the auto wreck lawyer can file charges against the guilty party for his client's medical expenses and future medical expenses. He can also file for damages for permanent scarring, loss of sick leave, mental anguish, physical pain, and other long-term issues. Without the knowledge of an informed lawyer the injured party would not have a complete understanding of auto accident insurance law.
