You must first report the crash to your insurance company to file an uninsured insurance claim. If it seems like you will need to use your uninsured insurance, the insurance company will go over your options. The process will usually begin with the insurance company starting an investigation into the collision. This means they will likely request and analyze numerous documents, such as your medical records and any other evidence related to the crash. Once their investigation is complete, they will try to put a dollar value on your claim. This whole process can take anywhere from a few weeks to a few months to complete and usually depends on the extent of your injuries.
