Learning that the at-fault driver is uninsured does not mean that you're unable to recover compensation.
You may still have options:
First, you may be able to turn to your insurance policy if you elected uninsured or underinsured (UM) coverage. In Georgia, this is not mandatory coverage for all drivers, but you may have purchased it with your original auto policy.
In other situations, you may be able to bring a lawsuit against the other driver and seek compensation at trial.
Your auto accident attorney can help evaluate your specific situation and determine what possibilities and avenues for recovery are available to you.
