Car insurance is required in both Washington and Oregon. In practice, a meaningful share of the drivers on the road carry none at all, and plenty more carry only the state minimum, which is nowhere near enough to cover a serious injury. If the driver who hit you falls into either group, the coverage that actually pays your claim is often not theirs. It's yours: uninsured motorist (UM) and underinsured motorist (UIM) coverage on your own policy.
Washington and Oregon handle this coverage differently in a few important ways, and we'll flag those differences throughout rather than treat the two states as interchangeable. Along the way, we'll walk through what UM/UIM coverage actually is, whose policy applies in different crash scenarios, how hit-and-run crashes fit in, what your options are when your own insurer won't pay, and a few situations, like small business vehicles and Oregon workers' comp claims, where the rules get more specific.
What Is Uninsured and Underinsured Motorist Coverage?
Uninsured motorist (UM) coverage pays you when the at-fault driver has no liability insurance at all. Underinsured motorist (UIM) coverage pays you when the at-fault driver has insurance, but not enough to cover the full value of your claim. Both types of coverage live on your own auto policy, and both work the same basic way: your insurer stands in for the at-fault driver's insurer and pays what you're legally entitled to recover, up to the limits of your own coverage.
Washington's statute (RCW 48.22.030) actually defines "underinsured motor vehicle" broadly enough to cover both situations in a single provision. It applies to a vehicle where no liability policy applies at the time of the crash, or where the liability limits that do apply are less than what you're legally entitled to recover. In other words, Washington doesn't treat "uninsured" and "underinsured" as two separate coverages requiring two separate elections. One provision handles both. Oregon's statute (ORS 742.502) structures it slightly differently, pairing a base uninsured motorist coverage with a required underinsurance component, but the practical effect for a policyholder is similar: if the at-fault driver can't fully pay for your injury, your own policy is what closes the gap.
Why It Matters in Both States
Both Washington and Oregon set the same minimum liability limits for drivers: $25,000 for the injury or death of one person, and $50,000 total per accident for the injury or death of two or more people. (Property damage minimums differ slightly, $10,000 in Washington versus $20,000 in Oregon, but that's a smaller piece of a serious injury claim.) A single hospital stay after a car accident can easily exceed $25,000. If the at-fault driver only carries the state minimum, or none at all, your medical bills, lost wages, and pain and suffering can quickly outrun what their insurance will ever pay.
That's the entire purpose of UM/UIM coverage: it exists because the legal minimum a driver has to carry is often far less than what a real injury costs.
How Washington and Oregon Handle the Coverage Differently
Oregon requires uninsured motorist coverage on every motor vehicle liability policy issued in the state, matching your bodily injury liability limits unless you sign a written statement electing lower limits. You can choose lower UM limits in Oregon, but you generally can't opt out of the coverage entirely.
Washington takes a more opt-out approach. Insurers must offer underinsured coverage in the same amount as your third-party liability coverage, but you (or your spouse) can reject it in writing. If your insurer can't produce that written rejection from your file, Washington law requires the coverage to be treated as if you had it. Insurance files aren't always as complete as they should be. If you're not sure whether you carry this coverage, check your policy declarations page or ask your agent directly.
Whose Policy Applies After a Crash?
This is one of the most common points of confusion, and the answer depends on the accident.
If the at-fault driver has no insurance or too little, your own UM/UIM coverage responds first, regardless of whose car you were in, subject to the rules below about which policy takes priority when more than one is available.
If you're a passenger in someone else's car, Oregon's statute is explicit about the order of operations: your own UM coverage applies as primary insurance only while you're occupying a vehicle you own. In a vehicle you don't own, your own coverage steps back and applies only as excess on top of any similar UM coverage attached to that vehicle, filling a gap if the vehicle's own coverage isn't enough. Washington's statute doesn't lay out that same primary/excess sequence. Instead, it caps your total recovery across multiple applicable UM/UIM policies at the higher of the applicable limits, rather than the sum of both. The practical result in both states is similar, you generally can't just add every available policy's limits together, but the mechanics differ, so more than one policy may be relevant and worth having reviewed.
Household policies can also come into play. Family members who live in the same household as a policyholder are often themselves "insured" for UM/UIM purposes under that household's policy, in addition to any coverage they carry personally. If you or a relative in your household were hurt while riding in someone's car, don't assume only one policy is relevant.
Hit-and-Run Crashes Are UM Claims
If the driver who hit you takes off before you get their information, that's not a dead end. Both Washington and Oregon treat hit-and-run crashes as a category of uninsured motorist claim, since you can't identify (and therefore can't pursue) a driver who fled the scene.
Both states also recognize "phantom vehicle" claims: situations where another vehicle caused you to crash, or forced you off the road, without ever making contact and without its driver being identifiable. Because there's no other driver to point to, both states require the facts to be corroborated by something beyond your own account (a witness, physical evidence, an officer's observations), and both require prompt reporting, notifying police or the relevant motor vehicle department within 72 hours for a phantom-vehicle claim to be considered. Oregon's statute additionally requires filing a sworn statement with your insurer within 30 days describing your claim against the unidentified driver.
The lesson here is simple. If you're the victim of a hit-and-run or a no-contact "forced off the road" crash, report it immediately, get a police report on record, and get in touch with your own insurer about a UM claim. Waiting to see if the other driver turns up is often the wrong move.
Small Business Owners and Company-Vehicle Coverage
If you're a small business owner who drives a business-registered vehicle for both work and personal use, don't assume your UM/UIM coverage follows you everywhere that vehicle does. Washington's statute specifically excludes coverage while you're operating or occupying a vehicle "owned or available for the regular use" of you or a family member that isn't insured under the policy's own liability coverage. In plain terms, if your everyday vehicle is titled to your business and covered under a separate commercial policy, your personal auto policy's UM/UIM coverage may not extend to it.
That cuts the other way too. A business auto policy's definition of who counts as an "insured" for UM/UIM purposes is set by the policy itself, and many commercial policies define coverage more narrowly around business use. This matters most for situations you might not expect, like a pedestrian injury: if you're struck by an uninsured driver while walking, whether your business policy's UM coverage applies can depend on whether you were doing something the policy treats as business activity at the time. Owning "a policy" doesn't mean you're covered in every situation; which policy applies, and what it covers, depends on the specific facts and the specific policy language.
If you run a business and drive a company vehicle regularly, know which policy, personal or commercial, covers you in which situations, rather than assuming the answer.
When Your Own Insurer Refuses to Pay
Filing a UM/UIM claim means making a claim against your own insurance company, which can feel strange since you're used to them being "on your side." Most of the time, the process works as intended. But disputes happen, over how badly you were hurt, whether all of your injuries came from this crash, or how much your claim is actually worth.
In Oregon, if you and your insurer can't agree, some UM policies include the option to resolve the dispute through arbitration rather than a lawsuit, but only if both sides agree to arbitrate at the time of the dispute. It isn't automatic, and either side can decline it in favor of court. In Washington, many insurers have moved toward requiring policyholders to file suit if a UM/UIM dispute can't be resolved informally, rather than offering arbitration.
If your own insurer denies your UM or UIM claim outright, or offers far less than your claim is worth, you're not without options. Washington's Insurance Fair Conduct Act gives first-party claimants, including people making UM/UIM claims under their own policy, the right to sue an insurer that unreasonably denies coverage, with the possibility of recovering treble damages and attorney's fees on top of what you were owed. We cover this process, including the notice steps you need to follow before filing suit, in detail in our guide to what to do after a denied insurance claim.
Oregon: Uninsured Motorist Claims and Workers' Compensation
If you drive for a living in Oregon and you're hurt on the job by another driver, workers' compensation isn't your only source of recovery, and Oregon law addresses how the two interact directly. Workers' comp pays medical bills and a portion of lost wages, but it generally doesn't cover pain and suffering or the full scope of what an injury costs you. When the driver who caused your crash isn't your coworker, you may also be able to pursue a claim against them directly, and if that driver was uninsured or underinsured, your employer's UM/UIM coverage on the vehicle you were driving can come into play.
Oregon's statute addresses this directly: any amount payable to you under UM/UIM coverage is reduced by the amount already paid, or payable, to you under workers' compensation for the same injury. Your UM/UIM benefits don't disappear because you also received workers' comp, but you also don't get to collect the same dollars twice. The statute is also clear that UM/UIM coverage isn't there to reimburse the workers' comp carrier itself; it exists for the injured worker.
If you were hurt while driving for work in Oregon and the other driver was uninsured, don't assume workers' comp is the end of the conversation. Ask whether the vehicle you were driving carried UM/UIM coverage, and if so, whether it's worth pursuing on top of your comp benefits.
Frequently Asked Questions
Is uninsured motorist coverage required in Washington and Oregon? It's required in Oregon: every motor vehicle liability policy issued there must include it, though you can sign a written election to lower the limits. Washington requires insurers to offer it at the same amount as your liability coverage, but you (or your spouse) can reject it in writing. If you're not sure which applies to you, check your policy declarations page.
What's the difference between uninsured and underinsured motorist coverage? Uninsured motorist coverage applies when the at-fault driver has no insurance at all. Underinsured motorist coverage applies when they have insurance, but not enough to cover your full claim. In Washington, one statutory provision covers both situations together. In Oregon, they're structured as a base coverage with a required underinsurance component.
Does uninsured motorist coverage cover hit-and-run accidents? Yes, in both states. Hit-and-run crashes, and no-contact "phantom vehicle" crashes, are treated as uninsured motorist claims precisely because you can't identify a driver to pursue directly. Report the crash to police within 72 hours, since both states require prompt reporting for this type of claim.
If I'm a passenger in someone else's car, whose uninsured motorist coverage applies? In Oregon, the vehicle's own UM coverage applies first, and your personal coverage applies only as excess if the vehicle's coverage isn't enough. Washington doesn't set that same order by statute, but generally caps your total recovery across multiple applicable policies rather than letting you add every limit together. Either way, more than one policy may be relevant, so it's worth having them all reviewed.
Can I collect uninsured motorist benefits and workers' compensation at the same time in Oregon? Often, yes. If you were hurt on the job by an uninsured or underinsured driver in Oregon, you may be entitled to both workers' compensation and UM/UIM benefits from the vehicle's policy. Oregon law reduces your UM/UIM payout by what workers' comp already paid or will pay for the same injury, so you won't collect the same amount twice, but the UM/UIM benefit isn't eliminated just because a workers' comp claim exists.
What happens if my own insurance company denies my UM or UIM claim? A denial isn't the final word. In Washington, the Insurance Fair Conduct Act gives you the right to sue an insurer that unreasonably denies a first-party claim, including UM/UIM claims, and to recover actual damages, potentially trebled, along with attorney's fees. See our full guide on handling a denied insurance claim for the steps involved.
