Comparative Negligence in Oregon: The 51% Bar

Oregon follows a modified comparative-negligence rule under ORS 31.600. A plaintiff whose share of fault is 50 percent or less may recover damages, reduced by that percentage. A plaintiff whose share of fault is 51 percent or more recovers nothing. This single statute drives most of the real fight in a Yamhill County injury case.

What ORS 31.600 actually says

ORS 31.600 directs the trier of fact, judge or jury, to compare the fault of every person whose conduct caused the injury and to assign each a percentage. The plaintiff's recovery is reduced in direct proportion to the plaintiff's own percentage of fault. If the plaintiff's percentage is greater than the combined fault of every defendant, the plaintiff recovers nothing.

How the math works

The cleanest way to see the rule is to walk through three concrete scenarios with the same total damages ($100,000) and three different fault splits:

• Driver A is found 30 percent at fault. Driver A recovers $70,000. The verdict is reduced by 30 percent.
• Driver A is found 50 percent at fault. Driver A recovers $50,000. The cap of partial recovery.
• Driver A is found 51 percent at fault. Driver A recovers $0. The bar drops.

Why fault percentage is the real fight

Insurers know the math, and they litigate accordingly. In many Yamhill County crash cases, the dispute is not whether there were injuries, that is documented in medical records, but how the percentages should be allocated. A shift from 49 percent to 51 percent is the difference between a full-value claim and no claim at all.

What gets weighed

Fault is not a single number a witness reads off a form. The jury weighs all of the conduct that contributed to the collision, including:

• Speed, lane position, and signal use at the moment of impact.
• Visibility, weather, and road conditions on Highway 99W or 18.
• Driver attention: phones, food, passengers, fatigue.
• Failure to yield, failure to maintain a lookout, failure to keep proper control.
• Mechanical condition of the vehicle: brakes, tires, lights.

Multi-defendant cases

When more than one defendant is at fault (for example, a chain-reaction collision) the plaintiff's percentage is compared to the combined fault of all defendants together. A plaintiff who is 40 percent at fault can still recover even if no single defendant was more than 30 percent at fault, so long as the defendants together exceed the plaintiff's share.

Why this matters at the first call

Comparative-negligence questions shape evidence collection from day one. Scene photographs, witness statements, vehicle inspection, and dashcam preservation all carry weight in the percentage allocation later. By the time an insurance adjuster offers a number, the file is largely built. The earlier counsel is involved, the more leverage there is on the percentage itself.
