Boise Uninsured and Underinsured Motorist Accident Lawyers

The driver who hit you had no insurance — or not enough. Idaho law and your own policy may cover the gap.

The driver who hit you had no insurance. Or they carried Idaho’s minimum — $25,000 per person — and your medical bills exceeded that number before you left the hospital. In either situation, Idaho law and your own auto policy can still provide full compensation for your losses. Uninsured motorist (UM) and underinsured motorist (UIM) coverage under Idaho Code Section 41-2502 is the bridge between the other driver’s inadequate coverage and what you are actually owed. We are happy to talk to you about your situation — call us, and one of our attorneys will review your policies and explain every option available.

Uninsured and underinsured drivers are a consistent problem on Idaho roads. The Insurance Research Council estimates that roughly one in eight drivers nationally operates without liability insurance. In Idaho, uninsured driver rates track that national average, meaning a statistically meaningful share of every crash on I-84, Eagle Road, Fairview Avenue, and every other Treasure Valley corridor involves a driver who cannot pay for what they caused. Even among insured drivers, Idaho’s minimum liability limits of $25,000 per person and $50,000 per accident are frequently exhausted by a single hospitalization for a serious crash — leaving injured victims with a coverage gap that their own UM/UIM policy is designed to fill.

Idaho’s UM/UIM Statute — Idaho Code Section 41-2502 in Plain Language

Idaho Code Section 41-2502 requires every auto liability policy issued in Idaho to offer uninsured and underinsured motorist coverage in amounts at least equal to the liability limits of the policy — unless the insured specifically rejects the coverage in writing. That means if you did not sign a written rejection form, your policy has UM/UIM at the same limits as your liability coverage. Most Idaho drivers carry more UM/UIM protection than they realize, because most people never signed a rejection form and therefore never opted out.

Uninsured motorist (UM) coverage pays when the at-fault driver has no liability insurance, when they are unidentified (a hit-and-run driver), or when a phantom vehicle caused the crash without making physical contact. For more on how UM coverage works specifically in hit-and-run situations, see our page on hit-and-run accidents in Idaho.

Underinsured motorist (UIM) coverage pays when the at-fault driver has insurance, but not enough to fully compensate your injuries. UIM picks up where the other driver’s policy stops — up to your own UIM limit. Idaho is generally a “difference of limits” state, meaning your UIM pays the spread between the at-fault driver’s limit and your own UIM limit, rather than paying on top of the full liability payment. Reading the actual policy language — not just the summary sheet — is essential to understanding exactly how your UIM stacks against the other driver’s coverage.

When Your UM Coverage Applies

UM coverage responds in a broader range of situations than most policyholders understand:

• The at-fault driver had no liability insurance at all.
• The at-fault driver fled the scene and was never identified — a hit-and-run crash.
• A phantom vehicle caused your crash by cutting you off or forcing you off the road without making physical contact. These “no-contact” UM claims are harder in Idaho and typically require independent corroboration — a witness, surveillance footage, or physical evidence beyond your own account.
• The at-fault driver’s insurer denied coverage because of a policy lapse, an exclusion, or fraud in the application.
• The at-fault vehicle was stolen and the owner’s policy excludes coverage for unauthorized drivers.

Stacking UM/UIM Coverage in Idaho

If you have more than one vehicle on your policy, or more than one auto policy in your household, stacking may allow you to combine UM/UIM limits across policies to increase the total available coverage. Whether stacking is available depends on the specific language of each policy and whether the insurer used a valid anti-stacking provision. Idaho courts have scrutinized anti-stacking clauses closely, and what the insurer says is not always what the policy actually does when applied to a specific claim. We read every relevant policy in the household before concluding that limits are capped at any particular number.

Illusory Coverage — When the Insurer Sold You Something That Pays Nothing

Idaho courts have recognized that UM/UIM coverage cannot be illusory — an insurer cannot sell coverage under one hand and take it away with exclusions under the other. When a UIM policy’s offset and anti-stacking provisions are structured so that the coverage would reduce to zero in the realistic scenarios it was sold to cover, those provisions can be unenforceable. These are technical coverage disputes that require attorneys who know Idaho insurance law in depth. Our team has practiced Idaho auto insurance coverage law for well over a combined 100+ years and has fought insurer coverage denials at every level.

How Insurers Undervalue UM/UIM Claims

Even when coverage clearly applies, insurance companies have a consistent playbook for reducing what they pay on UM/UIM claims:

• Calling your medical treatment excessive — they send your bills to a records review physician who has never examined you and whose opinion is purchased for the purpose of reducing the claim.
• Low-balling future medical care by ignoring recommended surgeries that have not yet occurred or rehabilitation that will be needed for years.
• Ignoring lost earning capacity for self-employed claimants, small business owners, and workers in physical trades whose ability to earn depends on physical function.
• Pushing comparative fault — arguing that you were partly responsible for the crash to chip at your recovery under Idaho Code Section 6-801’s 50 percent bar.
• Forcing arbitration prematurely under the policy’s UM/UIM arbitration clause before making a reasonable settlement offer. We know these provisions and how to respond to them.

The Two-Year Clock — and Why Your Own Insurer Is Not Your Friend on UM/UIM

Your UM/UIM claim is generally governed by Idaho’s two-year personal injury statute of limitations under Idaho Code Section 5-219. Some UM/UIM policies also carry their own contractual notice deadlines that can be shorter than two years and that must be met or the claim is waived. The single most important thing to understand about a UM/UIM claim is this: your own insurance company is adverse to you on that claim. They are not paying out of goodwill. They are a business defending a claim. Do not give a recorded statement, do not sign a blanket medical release, and do not accept a settlement figure without speaking with a lawyer first.

If you were in a hit-and-run crash or were injured by a driver with inadequate coverage, we are also experienced in handling the specific UM/UIM issues that arise in speeding crash cases where minimum-limits policies are common among the drivers who cause the most serious injuries.

What to Do Right Now

• Do not give a recorded statement to your own insurer before speaking with a lawyer. Even your own carrier is adverse to you on a UM/UIM claim.
• Locate the declarations page and full policy text for every auto policy in your household.
• Do not sign any UM/UIM release until you know the full scope of your injuries and any medical or legal lien positions that need to be resolved.
• Call Hepworth Holzer. We read the full policy, identify every available dollar of coverage, and fight for the full value of your claim.
