Personal Injury Laws in Oregon: Deadlines, Fault Rules & Damages

In Oregon, you generally have two years from the date of injury to file a personal injury lawsuit under ORS 12.110. Miss that window and, with rare exceptions, an Oregon court will dismiss the case no matter how strong it is. If a government agency or employee is involved, a much shorter notice deadline applies — as little as 180 days — so don't wait to find out which rule fits your situation.

This guide explains, in plain terms, how Oregon handles fault-sharing, damage limits, car-insurance claims, and dog bites, so you know what to expect before you talk to an insurer or a court. Laws and dollar amounts change, so always confirm current details against the official Oregon Revised Statutes or with an Oregon attorney before relying on anything here.

1. Oregon's Personal Injury Statute of Limitations

Oregon's general rule for personal injury — car crashes, slip-and-falls, assaults, product defects, and most other negligence claims — is two years from the date of injury, set out in ORS 12.110. Oregon courts apply a "discovery rule" in some cases, meaning the clock can start when you discovered, or reasonably should have discovered, that your injury was connected to someone else's conduct — but don't count on this extending your deadline; it's a narrow, fact-specific exception.

• Medical malpractice: also two years from discovery of the injury, but ORS 12.110 adds an outer limit — the claim must be brought within five years of the treatment or omission regardless of when it was discovered.
• Absolute outer limit: ORS 12.115 bars most negligence actions more than 10 years after the act or omission, no matter when the injury was discovered.
• Wrongful death: Oregon uses a separate statute with its own timeline (generally three years from death for most claims) — confirm the current deadline before assuming it matches the general two-year rule.

Because deadlines can be shortened or tolled by other circumstances (minority, incapacity, the type of defendant), verify your specific deadline against the current text of ORS 12.110 or with an Oregon court/clerk, rather than relying on a remembered rule of thumb.

2. Oregon's Shared-Fault Rule: Modified Comparative Negligence (51% Bar)

Oregon follows modified comparative negligence under ORS 31.600, using what's commonly called the "51% bar":

• If you are found 50% or less at fault, you can still recover damages — but your award is reduced by your percentage of fault. (Example: $100,000 in damages, 20% your fault, means a $80,000 recovery.)
• If you are found 51% or more at fault, ORS 31.600 bars you from recovering anything.

Fault is compared against the combined fault of the defendant(s), any third parties brought into the case, and parties who've already settled. Insurance adjusters routinely push a claimant's fault percentage up toward that 51% line because it can wipe out a claim entirely — treat any fault percentage an insurer assigns you as a starting negotiating position, not a final determination.

3. Damage Caps in Oregon

Non-economic damages (pain and suffering): Oregon had a statutory cap — historically $500,000 — on non-economic damages under ORS 31.710. In Busch v. McInnis Waste Systems (Oregon Supreme Court, 2020), the court held that cap unconstitutional as applied to personal injury claims under Article I, Section 10 of the Oregon Constitution (the "Remedy Clause"). The cap has been treated as unenforceable in most ordinary personal injury cases since that decision, though the legal landscape here has continued to shift — separately, the same cap has been treated differently for claims against public bodies under the Oregon Tort Claims Act, where the Oregon Supreme Court upheld it in Horton v. OHSU (2016). Confirm the current, case-specific status of any non-economic cap with an Oregon court or attorney rather than assuming it does or doesn't apply.

• Economic damages (medical bills, lost wages, future care costs) are not capped in Oregon.
• Punitive damages are not subject to a fixed dollar cap under ORS 31.730, but they require clear and convincing evidence of malice or reckless, outrageous indifference to a highly unreasonable risk of harm, and any jury award is subject to mandatory court review for excessiveness.

4. Oregon's Car-Insurance System: At-Fault, With Mandatory PIP

Oregon is an at-fault (tort) state for auto accidents — the driver who caused the crash (or their insurer) is financially responsible, and an injured person keeps the right to sue the at-fault driver. Oregon is not a true no-fault state that restricts your right to sue.

However, Oregon also requires every private passenger auto policy to include Personal Injury Protection (PIP) coverage under ORS 742.520, with a statutory minimum of $15,000 in medical benefits per injured person set out in ORS 742.524. PIP pays your own medical bills and related losses quickly, regardless of fault, while a liability claim against the at-fault driver is worked out separately — the two processes run in parallel, not instead of each other. Confirm current minimum PIP and liability coverage amounts with the Oregon Division of Financial Regulation, since minimums can be updated by the legislature.

5. Oregon's Dog-Bite Rule: A Hybrid, Not Pure Strict Liability

Oregon does not use a simple strict-liability or one-bite label — its approach is a hybrid, and which rule applies depends on what you're trying to recover:

• Economic damages only (medical bills, lost wages): Oregon holds dog owners strictly liable for these losses when their dog injures someone, without needing to prove the owner was negligent or knew the dog was dangerous.
• Full damages, including pain and suffering: to recover more than economic losses, you generally must show negligence, a violation of a local leash or animal-control ordinance, or that the owner knew (or should have known) the dog had dangerous tendencies — Oregon's version of the "one-bite" concept, which doesn't require an actual prior bite, only that a reasonable owner would have foreseen the risk.

Because this area blends statute, local ordinances, and case law, confirm the specifics for your situation with current Oregon statutes or a local court before assuming which theory applies.

Claims Against the Government: Oregon Tort Claims Act Notice

If your injury involves a city, county, state agency, school district, or other public body or its employee, your deadline is much shorter than two years. Under the Oregon Tort Claims Act, ORS 30.275 generally requires you to give formal written notice within 180 days of the injury (one year for wrongful-death claims). This notice is a separate, earlier step from filing the actual lawsuit, which must still be commenced within two years. Missing the 180-day notice window can permanently bar your claim even if you're still within the two-year lawsuit deadline — treat any potential government-involved injury as time-critical from day one.

What to Do in Oregon

1. Get medical care and document everything. Medical records anchor both your PIP claim and any later lawsuit.
2. Identify whether a government entity is involved (public road defect, transit vehicle, city employee, school). If so, treat the 180-day OTCA notice deadline as your real deadline, not two years.
3. Open a PIP claim with your own auto insurer promptly if a vehicle was involved — PIP pays medical bills regardless of fault and runs independently of any liability dispute.
4. Preserve evidence of fault — photos, witness names, police or incident reports — since Oregon's 51% bar means disputes over fault percentage can decide whether you recover anything at all.
5. Track the calendar. Note the date of injury and count forward under ORS 12.110 (or the shorter OTCA notice period), and don't rely on a "the insurer will let me know" assumption — insurers have no duty to warn you about your filing deadline.
6. File in the appropriate Oregon state court — generally Circuit Court in the county where the injury or defendant is located — if a claim can't be resolved with insurance. Small claims may be an option for lower-value disputes.
7. When in doubt on any deadline, cap, or rule, confirm directly with the current Oregon Revised Statutes or an Oregon attorney — this area changes with legislation and court decisions.
