Introduction to UM and UIM Coverage
In the world of auto insurance, liability coverage is designed to protect the assets of the at-fault driver by paying for the damages they cause to others. However, what happens when the at-fault driver does not have insurance, or their policy limits are too low to cover the victim's medical bills and vehicle repairs? This is where Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverages become essential.
For candidates preparing for the complete Claims Adjuster exam guide, understanding these first-party coverages is critical. While most auto insurance is designed to pay third parties, UM and UIM are unique because they allow the policyholder to collect benefits from their own insurance company as if that company were the insurer for the at-fault driver.
Comparing UM and UIM Coverage
| Feature | Uninsured Motorist (UM) | Underinsured Motorist (UIM) |
|---|---|---|
| At-Fault Party Status | Has no insurance or is a hit-and-run | Has insurance, but limits are insufficient |
| Triggering Event | Total lack of liability coverage | Exhaustion of at-fault party's limits |
| Purpose | Provides primary recovery for the victim | Fills the 'gap' between the loss and the at-fault limits |
Uninsured Motorist (UM) Coverage Deep Dive
Uninsured Motorist (UM) coverage applies when the person legally responsible for an accident has no auto liability insurance in effect at the time of the loss. It typically covers Bodily Injury (UMBI), though some jurisdictions also offer Property Damage (UMPD).
Key scenarios that trigger UM coverage include:
- The at-fault driver never purchased insurance.
- The at-fault driver’s insurance company is insolvent (bankrupt).
- The at-fault driver’s policy was cancelled prior to the accident.
- Hit-and-Run Accidents: In many states, a hit-and-run driver is classified as an uninsured motorist. However, many policies require "physical contact" between the vehicles for this coverage to apply to prevent fraudulent claims regarding 'phantom vehicles'.
When adjusting a UM claim, the adjuster must verify that the claimant is not at fault (or only partially at fault in comparative negligence states) and confirm the uninsured status of the other party.
The Concept of Stacking
On the Claims Adjuster exam, you may encounter the concept of stacking. Stacking allows an insured to combine UM/UIM limits from multiple vehicles to increase the total amount of coverage available for a single accident. For example, if an insured has two cars with $25,000 in UM coverage each, 'stacked' coverage would provide $50,000 in total protection.
Underinsured Motorist (UIM) Coverage Mechanics
Underinsured Motorist (UIM) coverage is slightly more complex. It applies when the at-fault driver has insurance, but their liability limits are lower than the damages sustained by the victim. UIM is designed to provide the "excess" or the "gap" coverage.
There are two primary methods used to calculate UIM payments depending on state law and policy language:
- Limits-to-Limits (Reduction): The insured’s UIM limit is reduced by the amount of the at-fault driver’s liability limit. If the victim has $100k in UIM and the at-fault driver has $50k in liability, the victim can only collect a maximum of $50k from their own UIM policy.
- Excess (Add-on): The UIM limit is added on top of the at-fault driver's limit. Using the same example, the victim could collect the full $100k of their UIM on top of the $50k from the at-fault driver, provided their actual damages warrant it.

The Role of the Adjuster in UM/UIM Claims
Adjusting UM and UIM claims requires a high level of diligence. Unlike a standard third-party claim, the adjuster's own company is effectively stepping into the shoes of the person who caused the accident. This can create an adversarial relationship with their own policyholder.
To succeed on practice Claims Adjuster questions, remember these steps in the UM/UIM process:
- Liability Investigation: Just because the other driver is uninsured doesn't mean they are 100% at fault. The adjuster must evaluate negligence.
- Verification of Coverage: The adjuster must obtain a formal denial of coverage or a copy of the declarations page from the at-fault driver's insurer.
- Evaluation of Damages: Medical records and bills must be reviewed to ensure the settlement is fair and reflects the actual loss.
- Exhaustion of Limits: In UIM cases, the adjuster must ensure the insured has already collected the maximum possible amount from the tortfeasor's insurance before UIM pays out.
Frequently Asked Questions
Yes, in many cases. If an insured is struck by an uninsured vehicle while walking, their own auto policy's UM coverage typically follows the person, not just the vehicle listed on the policy.
It depends on the state. Some states offer Uninsured Motorist Property Damage (UMPD), which covers the vehicle, while others only offer Bodily Injury (UMBI). In states without UMPD, the insured must use their Collision coverage (subject to a deductible) to repair their car.
A phantom vehicle is a vehicle that causes an accident (such as by cutting someone off) but does not make physical contact and flees the scene. Adjusters must be wary of these claims as many policies require physical contact for UM coverage to apply.
Subrogation is difficult because the at-fault party is, by definition, uninsured. If they could not afford insurance premiums, they are unlikely to have significant personal assets for the insurance company to seize to recover the claim costs.
