The short answer to this question is, probably not. Firstly, if you made a CLAIM against the other driver's insurer, USAA, and they settled with you, you were almost certainly required to sign a release. The release is an agreement to accept the agreed settlement amount as FULL compensation for your damages and a promise not to sue the driver. You cannot sue the insurer for the damages, though the insurer is the entity which pays them. If the insurer's offer of settlement was not enough, you should not have agreed to settle. Once you do and sign a release, you are forever barred from suing the driver over this accident. Secondly, if you did sue the driver and won a judgment, the insurer is responsible for paying the amount of the judgment, UP TO THE POLICY LIMITS. If, for example, you obtained a judgment for $30,000, but the driver's policy had a $25,000 limit, then the driver is personally responsible for the difference ($5,000). You don't sue the driver (again) for the difference, but there are legal devices you can use to collect that difference from the driver personally. You should consult an attorney for this purpose.
