Utah Uninsured & Underinsured Motorist Claims

UM vs. UIM — They're Not the Same Coverage

Utah drivers frequently confuse uninsured motorist (UM) and underinsured motorist (UIM) coverage, and carriers sometimes count on that confusion. They are two different coverages with different triggers:

• Uninsured Motorist (UM) — pays when the at-fault driver has no bodily injury liability coverage at all. Classic example: hit-and-run where the driver flees and is never identified. Or a driver who let their policy lapse. Or a driver who never carried coverage.
• Underinsured Motorist (UIM) — pays when the at-fault driver has some bodily injury liability, but not enough to cover your damages. Example: the at-fault driver carries Utah's $25,000 / $65,000 minimum liability, but your medical bills are $80,000. UIM covers the gap above the $25,000 (or $65,000 per-accident) they've tendered, up to your UIM limit.

Both coverages are governed by Utah Code § 31A-22-305 (UM) and § 31A-22-305.3 (UIM). Both are required to be offered by Utah carriers. Both can be rejected — but the rejection must be in writing, signed by the named insured. That written-rejection requirement is where a huge number of Utah drivers discover they have coverage they thought they didn't.

The Utah Written Rejection Rule — Read Your Declaration Page

Utah carriers must offer UM/UIM coverage at the time of every new policy and every renewal where no written rejection is on file. If you never signed a document declining UM or UIM, you have it — at statutory limits matching your liability (which, post HB 113 in 2024, means at least $25,000 per person / $65,000 per accident on UM; UIM typically matches or exceeds).

The first thing we ask any new UM/UIM client: bring in your declaration page. That's the one-page summary that comes with your policy showing coverages and limits. Look for the lines that say UM BI, UM PD, UIM BI. If the limits are listed, you have the coverage. If they say "rejected" or "declined," we ask the next question: is there a signed rejection in the file? If the carrier can't produce one, you have the coverage by operation of law — regardless of what the declaration page says.

Stacking — How One Household Can Access Multiple UM/UIM Limits

Utah allows intra-household stacking under certain conditions. That means: if you (or a family member with whom you reside) own multiple vehicles on multiple policies, you may be able to stack the UM/UIM limits across policies to increase total available coverage. Example:

• You own two cars on two separate policies. Each carries $50,000 UM. Stacked → $100,000 available.
• You live with a spouse who carries their own policy with $100,000 UIM. If the stacking language in both policies allows it, you may be able to access their UIM too.

Stacking is governed by the specific language of the policy and by Utah case law. Not every carrier's policy allows it, and some carriers write anti-stacking clauses that attempt to limit recovery to the highest single policy limit. Utah courts have enforced clear anti-stacking clauses in some cases and rejected ambiguous ones in others. A qualified Utah PI attorney reads every household policy, identifies every available layer, and pursues the highest recovery the law allows.

The Consent-to-Settle Trap — How to Not Destroy Your UIM Claim

This is the biggest procedural mistake unrepresented Utah drivers make. UIM only pays after the at-fault driver's liability limits have been exhausted. So if the at-fault driver's carrier offers you their policy limits (say, $25,000), you'd naturally want to take it and pursue UIM for the rest.

But most Utah UIM policies contain a consent-to-settle clause that says: before accepting the at-fault driver's limits, you must notify your own UIM carrier and give them a chance to either:

1. Pay you the at-fault driver's limits themselves — preserving their right to subrogate against the at-fault driver, or
2. Consent to the settlement — allowing you to accept the tender and pursue UIM separately.

If you accept the at-fault driver's tender without notifying your UIM carrier — or without giving them the legally required time to respond — you may have destroyed your right to pursue UIM entirely. Carriers enforce these clauses aggressively because it's a free escape hatch. The procedural timeline and notice form are policy-specific, which is why any Utah injury case involving a UIM layer should have a lawyer managing the settlement choreography before any money changes hands.

UM for Hit-and-Run — Proof Requirements

Hit-and-run crashes are the classic UM scenario: the at-fault driver flees, is never identified, and your own UM coverage becomes the only source. Utah UM claims for unidentified-driver cases require corroborating evidence beyond your own word that another vehicle caused the crash:

• Physical contact — most policies require that the at-fault vehicle actually struck your vehicle (phantom-vehicle cases where you swerve to avoid and crash are treated differently and are more restrictive).
• Police report — file one. An UHP or local-department accident report is essential.
• Independent witness — someone not in your vehicle who saw the crash.
• Physical evidence at the scene — paint transfer, debris, skid marks, broken parts.
• Prompt notice to your carrier — under your policy's reporting timeline, typically within 24–72 hours.

Damages Available in a Utah UM/UIM Claim

UM/UIM pays the same categories of damages that the at-fault driver's liability would have paid, up to your policy limit:

• Past and future medical expenses
• Lost wages and loss of earning capacity
• Pain and suffering (no statutory cap in Utah PI)
• Mental anguish
• Loss of consortium (spouse's claim)
• Loss of enjoyment of life
• Disfigurement and scarring
• Future medical care projected over life expectancy

Property damage (vehicle repair, diminished value, total loss) typically flows through Utah's UM-PD coverage or comprehensive/collision, not the UM-BI limit. The dual-claim framework applies here too — see the dual-claim explainer.

Bad-Faith Exposure — When Your Own Carrier Is the Opponent

UM/UIM claims have an unusual dynamic: your own insurance company is the defendant. They collected your premium and owe you a duty of good faith under Utah law, but they also have a financial incentive to minimize what they pay. When a UM/UIM carrier delays, denies, or lowballs a Utah claim, they may cross the line into bad faith exposure.

Utah's bad-faith doctrine — anchored in Beck v. Farmers Insurance Exchange and the Utah Unfair Claims Practices Act under § 31A-26-303 — requires the carrier to act as a reasonable party to its own contract. That means timely investigation, good-faith evaluation, fair settlement offers, and honest communication. When they don't, their conduct creates a separate cause of action with extracontractual damages — potentially including emotional distress, attorney's fees, and punitive damages under § 78B-8-201.

We preserve bad-faith documentation from day one on every UM/UIM file: the claim report, the estimate, the delay log, every lowball offer, every unreturned phone call. If the carrier plays games, the file is already built to file the bad-faith suit.

Statute of Limitations — Two Clocks Running

UM/UIM claims run on two clocks simultaneously:

• The underlying PI claim — 4 years from the date of injury under § 78B-2-307.
• The contract claim against your own UM/UIM carrier — typically 6 years from accrual under § 78B-2-309, but policies often contain shorter contract-based reporting deadlines (often 3 years or "as soon as practicable" notice requirements).

Whichever runs first is what kills your claim. The rule of practice: don't wait. Notify the UM/UIM carrier in writing as soon as the crash happens, even if you don't yet know whether the at-fault driver is underinsured.

When to Call an Attorney on a UM/UIM Case

Some UM/UIM claims are simple and you can probably handle them yourself — minor injury, clear liability, well-documented medical bills under the policy limit, one carrier. A Utah attorney adds value in these situations:

• Your medical bills approach or exceed the at-fault driver's liability limits.
• The UM/UIM carrier is your own carrier and they're delaying or lowballing.
• There are multiple policies in the household that might stack.
• The at-fault driver is offering their limits and you don't know the consent-to-settle process.
• You suspect bad-faith conduct by your own carrier.
• Liability is disputed and the UM/UIM carrier is using that to deny.
• Injuries are permanent, surgical, or catastrophic.
