Introduction to UM and UIM Coverage
In the world of personal auto insurance, liability coverage is designed to pay for the damages you cause to others. However, a significant gap exists when the situation is reversed: what happens if someone else hits you and they don't have insurance, or their limits are too low to cover your medical bills? This is where Uninsured Motorist (UM) and Underinsured Motorist (UIM) coverages become essential components of a robust personal lines policy.
For students preparing for the complete Personal Lines exam guide, understanding the triggers and application of these coverages is vital. These coverages are unique because they essentially allow your own insurance company to 'step into the shoes' of the at-fault driver's insurer to pay for your losses. To ensure you are ready for the test, you should also practice with practice Personal Lines questions.
Uninsured (UM) vs. Underinsured (UIM)
| Feature | Uninsured Motorist (UM) | Underinsured Motorist (UIM) |
|---|---|---|
| At-Fault Party Status | Has no insurance at all | Has insurance, but limits are insufficient |
| Hit-and-Run | Generally covered (BI only) | Not applicable |
| Trigger | Total lack of liability coverage | Exhaustion of at-fault party's limits |
| Primary Goal | Protects against lawbreakers | Protects against inadequate limits |
Understanding Uninsured Motorist (UM) Coverage
Uninsured Motorist (UM) coverage provides protection for the insured when they are involved in an accident where the at-fault driver is legally liable but carries no insurance. On the Personal Lines exam, you must recognize the three specific scenarios that trigger UM coverage:
- The No-Insurance Driver: The at-fault driver has no liability policy in effect at the time of the accident.
- The Hit-and-Run Driver: The at-fault driver cannot be identified. In most jurisdictions, UM coverage applies to Bodily Injury in hit-and-run cases, provided there is proof of physical contact.
- The Insolvent Insurer: The at-fault driver has insurance, but their insurance company has become insolvent (bankrupt) and cannot pay the claim.
UM coverage typically applies to Bodily Injury (UMBI), covering medical expenses, lost wages, and pain and suffering. Some states also offer Uninsured Motorist Property Damage (UMPD), which covers damage to your vehicle, often with a specific deductible.
Key UM/UIM Statistics & Facts
The Mechanics of Underinsured Motorist (UIM) Coverage
Underinsured Motorist (UIM) coverage applies when the at-fault driver has insurance, but their liability limits are lower than the damages sustained by the insured. There are two primary ways UIM is calculated, depending on state law and policy language:
- Difference in Limits (DIL): The insured’s UIM limit is reduced by the amount recovered from the at-fault driver. For example, if you have $100,000 in UIM and the at-fault driver has $25,000 in liability, your policy provides a maximum of $75,000 ($100k - $25k).
- Excess Coverage: The insured’s UIM limit is added on top of the at-fault driver’s limit. In the same scenario, you would have $100,000 available after the $25,000 from the at-fault driver is exhausted.
Exam Tip: UIM coverage is only triggered after the at-fault party's liability limits have been fully exhausted by payment of judgments or settlements.
Stacking vs. Non-Stacking
On the exam, you may encounter the concept of stacking. Stacking allows an insured to multiply their UM/UIM limits by the number of vehicles insured under the policy (Intra-policy) or across different policies (Inter-policy). If an insured has three cars with $50,000 UM coverage each, 'stacked' coverage would provide $150,000 in total protection for a single accident.
Arbitration and Legal Recourse
Since UM/UIM claims involve the insured making a claim against their own insurance company, disagreements can arise regarding the amount of damages or the extent of the at-fault driver's liability. To resolve these disputes without lengthy court battles, many policies include an Arbitration Clause.
Under arbitration, both the insured and the insurer select an independent arbitrator. These two then select a third arbitrator. A decision reached by any two of the three is typically binding. This process is focused strictly on two issues: Is the insured legally entitled to recover damages? and What is the amount of those damages?
