Yes, it is generally possible to add additional drivers to a GAINSCO auto insurance policy. Most insurance providers, including GAINSCO, allow policyholders to include additional drivers, which can provide coverage and protection for those individuals while operating the insured vehicle. It is important for policyholders to ensure that all drivers listed on the policy are accurately disclosed, as failing to do so may impact claims in the event of an accident. The specific process for adding drivers and any associated fees or requirements can vary, so it is advisable to refer to the GAINSCO insurance policy details or consult the official website for more information. The website may provide clarity on how to proceed with this request and any documentation that may be required.
