Uninsured & Underinsured Motorist Coverage
Oregon UM/UIM coverage protects an insured when the person responsible for a crash has no collectible liability insurance or does not provide enough insurance to pay the insured's legally recoverable damages. Oregon defines this protection in detail by statute—including who is insured, what vehicles qualify, how limits are selected, what happens with hit-and-run and phantom vehicles, and how a liability settlement must be coordinated with the UM/UIM insurer.
UM/UIM is insurance purchased to protect the insured
Liability insurance protects an insured against claims made by other people. UM/UIM reverses the direction of the protection: the insured makes a first-party claim under the insured's own coverage because the responsible motorist lacks adequate liability insurance.
Oregon's statutory definition also addresses coverage denial, insolvency, hit-and-run, phantom and certain self-insured situations.
Current Oregon law examines the amount actually recovered and the insured's legally recoverable damages, subject to the UM/UIM limit and statutory policy terms.
That creates contractual notice, proof, settlement-consent, subrogation, priority and claim-preservation questions separate from the tort claim.
Oregon UM/UIM limits generally follow bodily-injury liability limits
ORS 742.502 establishes matching UM limits as the starting point but permits a qualifying written election of lower limits.
The bodily-injury UM/UIM limit generally equals the policy's bodily-injury liability limit.
A named insured may elect lower UM/UIM limits through Oregon's statutory written-election process.
An elected lower UM/UIM limit cannot fall below Oregon's minimum bodily-injury limits under ORS 806.070.
Recent Oregon Court of Appeals authority in Progressive Universal Insurance Co. v. Voyles addresses the statutory signed-writing requirement and the meaning of “a named insured” for a lower-limit election.
Oregon now uses a damages-based UIM structure
Older Oregon cases and insurance materials can be misleading because Oregon's UIM statute materially changed in 2015.
Many pre-2015 Oregon cases were decided under statutory language comparing the tortfeasor's liability limits with the insured's UM/UIM limits.
Current law asks whether liability recovery is less than the damages the insured is legally entitled to recover and permits UIM benefits subject to the UM/UIM coverage limit.
Insured status depends on the person and the vehicle
ORS 742.504 supplies minimum statutory definitions that a required Oregon UM/UIM policy may not make less favorable to the insured.
| Potential insured | Oregon statutory starting point |
|---|---|
| Named insured | The person identified as the named insured is within the statutory UM/UIM definition. |
| Resident spouse | A spouse residing in the named insured's household is included, subject to statutory qualifications concerning ownership of undescribed vehicles. |
| Resident relatives | Qualifying resident relatives are included, again subject to Oregon's statutory vehicle-ownership qualification. |
| Child being reared as insured's own | Oregon specifically includes a child residing in the household whom the insured has reared as the insured's own even without blood, marriage or adoption. |
| Passenger / other occupant | Another person occupying an insured vehicle generally qualifies where the vehicle's actual use is with the named insured's permission. |
“Uninsured vehicle” means more than a driver with no policy
ORS 742.504 contains a broader statutory model definition designed to address several ways liability protection may be unavailable.
| Situation | Oregon UM starting point |
|---|---|
| No collectible insurance | Vehicle lacks collectible bodily-injury liability insurance at least equal to Oregon's statutory minimum applicable at the time of the crash. |
| Liability carrier denies coverage | Oregon's model definition expressly includes circumstances where otherwise applicable liability insurance exists but the insurer denies coverage. |
| Insurer insolvency | Statutory definition addresses bankruptcy, receivership and insolvency circumstances. |
| Unknown insurance | After reasonable efforts, failure by insured and insurer to discover valid collectible liability insurance within 90 days creates a disputable statutory presumption that the vehicle is uninsured. |
| Hit-and-run | A qualifying hit-and-run vehicle is included within the statutory definition, subject to the specific reporting and proof rules. |
| Phantom vehicle | Oregon recognizes qualifying no-contact accidents where the unidentified vehicle causes the crash and statutory corroboration and reporting requirements are met. |
| Stolen vehicle | Certain accidents involving a stolen insured vehicle are expressly addressed by Oregon's statutory UM model. |
| Self-insured vehicle | Oregon includes specified self-insured situations involving statutory noncompliance or inadequate recovery. |
Hit-and-run and phantom claims contain short procedural deadlines
These claims can fail long before an ordinary tort limitations period expires if the statutory insurance procedures are ignored.
Oregon's bodily-injury statutory model generally requires physical contact between the unidentified vehicle and the insured or a vehicle the insured is occupying.
A phantom vehicle can cause a covered accident without physical contact, but independent competent corroborating evidence is required.
The statutory model requires timely reporting to an appropriate police, peace or judicial officer, Oregon DOT or equivalent agency.
A sworn statement describing the claim and supporting facts must generally be filed with the insurer.
Competent evidence other than testimony of persons asserting UM claims from the accident must corroborate the event.
A liability settlement must be coordinated with the UIM carrier
Oregon's statutory model protects the UM/UIM insurer's subrogation rights while also placing a definite outside limit on the ordinary time allowed to evaluate a written consent request.
Determine the offered amount, applicable limits, release terms and whether the liability carrier represents that its limits are exhausted.
Give the UIM insurer enough information to evaluate the proposed settlement and preserve proof of delivery.
Oregon requires prompt production of reasonably requested information within the insured's custody and control.
Oregon defines reasonable response time as no more than 30 days after the insurer receives the written consent request unless the parties agree otherwise.
The statute provides mechanisms for proceeding when the carrier refuses consent, but they depend on protecting the insurer's rights against the tortfeasor.
Confirm the document preserves every claim and first-party right that should remain open.
Oregon UM/UIM has a critical two-year preservation structure
Do not confuse the ordinary tort statute of limitations with the contractual/statutory timing structure for preserving a UM/UIM claim.
The insured and carrier conclude an agreement concerning the amount payable under the policy.
Where arbitration is mutually elected, formal institution of the proceeding can satisfy the statutory preservation requirement.
An insured can preserve the claim through the statutory litigation route.
Oregon provides a separate route involving timely bodily-injury suit against the uninsured motorist followed by arbitration or action against the insurer within the additional statutory period after settlement or final judgment.
Oregon UM/UIM arbitration is not automatically mandatory
ORS 742.504 provides an arbitration route when the insured and insurer disagree over legal entitlement to damages or the amount payable.
ORS 742.505 provides a three-arbitrator procedure unless the parties agree otherwise. Oregon law limits the insured's arbitration costs under the statutory model, although attorney fees and expenses involved in producing evidence or witnesses are treated separately.
More than one UM/UIM policy may apply
Oregon's statutory model contains priority rules for UM/UIM coverage, and ORS 742.506 addresses allocation between insurers.
ORS 742.504 establishes a statutory primary-coverage rule where the insured is occupying a vehicle owned by a named insured under that coverage.
Where the insured occupies a vehicle not owned by a named insured, the statutory model addresses the relationship between primary similar insurance and excess UM/UIM.
PIP payments and UM/UIM are coordinated—but the limit remains intact
Oregon has a separate statutory rule addressing PIP payments made by the same motor-vehicle insurer and the damages recoverable under UM/UIM.
The statutory system coordinates amounts already paid as PIP with damages otherwise payable under UM/UIM.
Oregon expressly distinguishes adjustment of damages from reduction of the UM/UIM policy limit itself.
The broader PIP reimbursement and full-compensation system is developed in Guide 21 .
Uninsured-motorist property-damage coverage is a separate Oregon product
The mandatory bodily-injury UM/UIM system should not be confused with Oregon's separate uninsured-motorist property-damage statute.
That coverage has its own statutory definitions, deductibles and limitations. It is not the same thing as bodily-injury UM/UIM under ORS 742.502.
Important Oregon UM/UIM authorities
Oregon's UM/UIM cases span several versions of the statute. Always identify which statutory text the court was interpreting before applying an older decision to a current claim.
Fundamental Oregon statutory-model case. Policy terms are compared with the statutory UM model, and provisions that make coverage less favorable to the insured are not permitted.
Leading phantom-vehicle authority concerning corroboration, statutory protection and compliance with notice requirements.
Major multiple-policy authority. Oregon's statutory model prevented enforcement of policy language that would provide coverage less favorable than the statutory multi-policy result.
Illustrates the statutory-model principle where policy language attempted to define the covered vehicle concept more narrowly than Oregon's UM statute permitted.
Recent authority interpreting Oregon's statutory process for electing UM/UIM limits lower than bodily-injury liability limits. Supreme Court review was denied.
Confirms the importance of the elective arbitration structure and the insured's ability to demand judicial resolution rather than automatically being forced into arbitration.
Oregon UM/UIM citizen workflow
Vehicle policy, claimant policy, household policies and any other policy under which the injured person may qualify as an insured.
Named insured, household member, child, passenger or other qualifying occupant status should be analyzed separately.
Compare the limits with bodily-injury liability limits and obtain any statutory lower-limit election relied upon by the insurer.
Do not postpone first-party notice while waiting for the tortfeasor's liability claim to mature.
If the responsible vehicle is unidentified, address the 72-hour and 30-day statutory procedures immediately.
Current Oregon UIM law cannot be analyzed correctly without knowing the insured's legally recoverable damages.
Obtain the tortfeasor policy information, settlement offer and allocation where several injured persons share limited proceeds.
Send the liability settlement information to the UIM carrier before releasing the tortfeasor and calendar the statutory response period.
Determine which statutory preservation route will be used before the deadline approaches.
Do not assume the policy on the occupied vehicle is the only applicable first-party motorist coverage.
Track PIP paid and determine how ORS 742.542 affects damages without improperly reducing the UM/UIM limit.
Policies, elections, claim notices, consent requests, insurer responses, liability settlement documents, medical evidence, arbitration communications and deadline records.
