This coverage can be added to the policy to supplement the uninsured motorist coverage. The coverage must be added to all automobiles listed on the policy.

This is when the insured's underinsured motorist coverage would apply and payment for the difference could be made. The two coverages are mutually exclusive and do not overlap or duplicate each other. An insured can collect under one coverage or the other but not under both. Back to list of terms.
