If the driver fled the accident scene, you may feel like you have no legal options. However, this isn't necessarily true. After all, the police may eventually locate the liable driver. At that point, you could file a claim or a lawsuit to hold them responsible.
If police never find the driver, you may have to work with your own insurance coverage. You may have purchased uninsured or underinsured motorist coverage. You can use it to claim compensation if you're the victim of a hit-and-run accident since the party that fled the scene effectively lacks insurance coverage for the purposes of your case.
