An Act to relative to an underinsurance issue

This bill amends Massachusetts insurance laws to clarify how uninsured motor vehicle coverage works when a tortfeasor's liability limit is reduced by multiple claims from the same accident. Specifically, it ensures that an insured driver can still access their own uninsured motor vehicle coverage up to the remaining amount of the tortfeasor's original policy limit after those payments are made. The change directly affects drivers in Massachusetts who are involved in accidents where the at-fault party's insurance has been partially exhausted by other claims. By adding this provision, the legislation aims to prevent gaps in coverage that could leave victims undercompensated when the at-fault driver's insurance is insufficient.
