Uninsured motorist coverage rules in Oregon

In Oregon, UM/UIM coverage is mandatory and defaults to your own liability limits. A 2015 law (SB 411) ended the old offset so your coverage now stacks on top of the at-fault driver's limits, and a separate two-year deadline governs the claim.

Uninsured motorist coverage rules in Oregon

If the driver who hit you had no insurance, too little insurance, or fled the scene, the coverage that actually pays your medical bills and lost income is usually your own uninsured/underinsured motorist coverage (UM/UIM). Oregon's rules for it are specific, and a 2015 law rewrote the part that matters most. Here is what applies in Oregon.

Every Oregon auto policy already includes it

Oregon does not treat UM/UIM as optional. ORS 742.502 requires every motor vehicle liability policy sold in the state to carry uninsured motorist coverage, and that coverage has to include underinsurance benefits.1 The default limits are not the bare state minimum. They equal your own bodily injury liability limits, unless a named insured signs a written statement electing lower limits, and that signed statement has to be completed within 60 days of the election.1 You can never drop below the statutory floor of $25,000 per person and $50,000 per crash for bodily injury, the same minimum ORS 806.070 sets for liability.2 The waiver form is approved by the Department of Consumer and Business Services and has to state, in plain terms, what the full-limit and lower-limit coverage would cost, so electing less is a deliberate act rather than a box an agent checked.1

One point that trips people up: this coverage is for bodily injury and death, not for your car. Damage to the vehicle itself runs through collision coverage or a diminished value claim, not UM/UIM.

What counts as uninsured or underinsured here

ORS 742.504 defines an "uninsured vehicle" broadly. It reaches a driver with no collectible bodily injury liability coverage, a driver whose insurer went insolvent, a hit-and-run vehicle, a "phantom" vehicle that causes a crash without ever touching you, a stolen vehicle, and certain self-insurers who are out of compliance.3

Two of those categories come with reporting rules. For a hit-and-run or phantom vehicle, you or someone acting for you must report the crash within 72 hours to a police or judicial officer or to ODOT, and file a sworn statement with your insurer within 30 days.3 A phantom-vehicle claim also has to be corroborated by evidence beyond your own testimony.3

"Underinsured" is the more common case: the at-fault driver had coverage, just not enough to cover what you are legally entitled to recover. ORS 742.502 defines underinsurance benefits as the damages you are legally entitled to recover, up to your UIM limit, when the other driver's coverage comes up short.1

The 2016 change that made Oregon coverage far more valuable

This is the Oregon rule worth knowing. Before 2016, UIM here worked by subtraction. If you carried $100,000 in UIM and the at-fault driver paid $25,000, your insurer subtracted that $25,000 and capped you at $75,000.

Senate Bill 411, enacted as chapter 5 of the 2015 Oregon Laws, struck that offset language out of the statute.4 For policies issued or renewed on or after January 1, 2016, your UIM limit is no longer reduced by what the other driver's insurer pays.4 Your UIM coverage now sits on top of the at-fault driver's liability limits. In the same example, the $25,000 from the at-fault driver and your $100,000 in UIM stack, so up to $125,000 is available, capped by your actual damages.4

The trigger changed too. You have a UIM claim whenever your damages exceed the at-fault driver's available bodily injury coverage, measured against what you are legally entitled to recover instead of a limit-against-limit comparison.1 SB 411 used the same policy year as the start date for a longer PIP medical benefit as well.4

Exhaust the other driver first, and get your insurer's sign-off

UIM is a backstop, so Oregon makes you work through the at-fault driver's coverage first. Under ORS 742.504, UIM benefits do not apply unless the other driver's liability limits have been exhausted by settlement or judgment, or you give your insurer credit for the unrealized portion as if the full limits had been paid.5

Before you accept a settlement from the at-fault driver, you generally need your own insurer's consent, or you have to protect its right to pursue that driver (subrogation).5 The insurer gets a reasonable time to respond to a settlement request, which the statute defines as no more than 30 days from a written request unless you both agree otherwise; if it does not respond in time, consent is presumed.5 Skipping this step can sink an otherwise valid UIM claim, so get the request in writing early.

The deadline most people miss

The ordinary deadline to sue over a crash injury in Oregon is two years from the date of the collision under ORS 12.110(1).6 Your UM/UIM claim carries its own, separate two-year clock, and it is easy to blow.

ORS 742.504(12) says no claim accrues against your own insurer unless, within two years of the accident, one of these has happened: you and the insurer reach an agreement on the amount owed, arbitration has been formally started, or you have filed an action against the insurer.7 There is one alternative path. If you filed suit against the at-fault driver within that two-year window, you then get two years from the settlement or final judgment in that case to demand arbitration or sue your insurer.7

Because this is a contract deadline written into the policy, it runs independently of the injury statute of limitations, and settling with the at-fault driver's insurer does not preserve it. If your recovery depends on UM/UIM, treat that two-year mark as a hard wall and act well before it.

How disputes get resolved

When you and your insurer disagree about fault or the value of the claim, ORS 742.504 lets you resolve it through arbitration by mutual agreement.8 The cost rules favor the insured: your share of the arbitration costs is capped at $100, and the insurer pays the rest.8 The arbitration takes place in the county where you live or where your claim against the at-fault driver arose.8

Where PIP and fault fit in

Oregon is a fault state with mandatory PIP layered on top, so your own PIP pays first no matter who caused the crash. PIP covers at least $15,000 in medical expenses incurred within two years, 70 percent of lost wages up to $3,000 a month for 52 weeks, and a $5,000 funeral benefit, under ORS 742.524.9

PIP and UIM connect through a "make whole" rule that SB 411 also tightened. Under ORS 742.544, your PIP insurer can be reimbursed out of your recovery only to the extent your total recovery (UIM benefits, liability payments, and PIP combined) exceeds your actual damages, and you never have to repay more than the PIP you actually received.10 In practice, your PIP carrier cannot pull money out of your UIM settlement until you have been fully compensated.

Fault still affects the size of a UIM recovery. Oregon uses modified comparative negligence with a 51 percent bar under ORS 31.600, so partial fault reduces your recovery by your percentage, and anything at 51 percent or higher wipes it out.11

If you are dealing with this now

A UM/UIM claim is a claim against your own insurer, and the deadlines and consent rules hand that insurer a lot of technical defenses. If the driver who hit you was uninsured, underinsured, or gone, and especially if you are anywhere near the two-year mark, talk to an attorney (you can find one here) before you sign anything. If you still need the official crash documentation, that runs through the Oregon crash report process.
