If you were hurt in a car accident, you may need a lawyer to help you collect and analyze evidence that establishes who was at fault and what your injuries are worth. For example, most newer vehicles are equipped with a piece of recording technology known as a “black box” that records critical information during a car accident. This information may establish how fast the car was going at the time the accident occurred, or whether the driver was wearing a seatbelt. In order to access the other driver’s data recorder, you may need a court order for this type of data, and a lawyer can help you request one as part of a lawsuit.
