Why Hiring a Car Accident Attorney is Important A car accident attorney can help you if you have been involved in an accident that results in you being injured. An attorney can assist you to file a lawsuit against the driver who caused the collision. They will also send experts in crash reconstruction to the scene to determine the exact causes of the crash and determine the driver at fault. If you can prove that the at-fault driver had insurance that covered the crash, you could be able to get compensation from the driver's insurance company.
