After an accident with an uninsured driver, knowing how to file an uninsured motorist claim can help you protect your rights. Even though Illinois mandates automobile insurance, many drivers don't have sufficient coverage. In an accident involving an uninsured driver, you might need to seek benefits from your own insurance provider. To do so, you will need to have a good grasp of the law, your insurance policy, and the steps to take when handling a situation involving an uninsured driver.
