What Is Underinsured Motorist Coverage?
Underinsured Motorist Coverage is insurance protection that may help pay covered injury losses when a responsible driver’s liability insurance cannot cover the full value of those losses. The injured person’s policy, coverage limits, exclusions, and claim facts control whether benefits apply and how much compensation may remain available.

How Underinsured Motorist Coverage Works

Underinsured Motorist Coverage applies when another driver caused a crash but that driver’s liability policy does not cover the injured person’s covered losses. The available recovery depends on the policy language, the injury evidence, and the amount of liability insurance available. The claim may involve the injured person’s own insurer after the other driver’s coverage is considered.

Liability insurance pays according to the responsible driver’s policy. Underinsured coverage addresses the remaining covered loss subject to its own terms and limits. The insurer may review medical records, wage-loss evidence, crash facts, and settlement information. A policy may also contain notice provisions, consent requirements, exclusions, or rules affecting how coverage applies.

From the Atlanta Auto Law team
When we review an underinsured motorist claim, we examine every applicable policy and compare its terms with the crash facts. We also organize medical records, liability information, and documented losses before addressing the insurer’s position. That review helps identify coverage issues that may not appear in the other driver’s policy.
Underinsured Motorist Coverage in Practice: A Real-World Example
A driver causes a collision and carries liability insurance, but the available policy does not cover the injured person’s medical treatment and other documented losses. The injured person’s underinsured motorist policy may provide additional coverage, subject to its terms and limits.
