Connecticut UM/UIM Stacking Calculator

Connecticut does not let you add up the uninsured and underinsured motorist limits of several vehicles or policies, and ordinary UIM pays only up to your own limit after the other driver's limits are used. An optional conversion coverage works differently. Enter your limit, your damages and what the at-fault driver paid.

Connecticut bans stacking by statute

Connecticut's rule is in General Statutes 38a-336. Subsection (d) bars adding together the limits of several vehicles or policies, subsection (e) defines an underinsured vehicle, and 38a-336a sets out the optional conversion coverage. Insurers have no subrogation right against the underinsured driver under 38a-336b.

Read why Connecticut does not stack coverage, check what subsection (d) says about several policies, or see how UM, UIM and conversion coverage differ.
