You were in a crash. And now someone, an insurance adjuster, the other driver, maybe both, is suggesting you were partly responsible for what happened.
That word “partly” carries a lot of weight. It can make people feel like their claim is in jeopardy, or like they have no case at all. Most of the time, that’s not true. Oregon law is built for exactly this situation, and understanding how it works can be the difference between walking away with something and walking away with nothing.
What Is Fault in a Car Accident?
In legal terms, fault means “negligence.” A driver failed to act with reasonable care, and that failure caused the crash.
Reasonable care is the standard every driver is held to on the road. It means following traffic laws, paying attention, adjusting your speed for conditions, and generally driving the way a responsible person would. When a driver falls short of that and someone gets hurt, they’re considered at fault.
In real life, fault can come from a lot of directions. Running a red light is fault. So is following too closely, failing to yield, driving drunk, or checking your phone at the wrong moment. But fault isn’t always tied to an official traffic violation. It doesn’t require a ticket. A driver who hesitated at the wrong moment, misjudged a gap in traffic, or didn’t account for wet roads can still be found negligent, even if nothing in the police report flags them for a violation.
What Comparative Negligence Means for Your Claim
Comparative negligence is Oregon’s legal framework for handling crashes where more than one person contributed to what happened.
The law doesn’t require a black-and-white situation to award compensation. It just requires evidence of what each person did or didn’t do, and how that contributed to the outcome.
Oregon divides fault like a pie. Whatever slice of fault belongs to you gets subtracted from what you can recover. If you’re responsible for 30% of the crash, you lose 30% of your damages. The rest is still yours. Oregon draws the line at 51%. If your share of fault lands there or higher, you can’t recover anything.
So on a $100,000 claim, 30% fault means you walk away with $70,000. That’s still a meaningful recovery, which is exactly why insurers push hard to get your fault percentage as high as possible.
What to Do If You Think You Were Partly at Fault
The instinct most people have in the moments after a crash is to apologize. It’s human. If you said sorry at the scene, or told the other driver you didn’t see them coming, you’re not alone and it’s not necessarily fatal to your claim. What matters now is what you do next.
See a doctor, even if you feel okay. Adrenaline has a way of masking things, and whiplash or a concussion can take days to announce itself. The longer you wait, the easier it becomes for an insurer to argue the crash wasn’t the cause.
If you haven’t already, write down everything you can remember while it’s still reasonably fresh. Our memories fade faster than we might think, so recording your recollection of the events is important. What was the sequence of events? What were the road conditions like? What did you see before the impact? What was said at the scene?
Beyond that, you don’t have to figure out what to gather or where to look on your own. That’s our job. We know what evidence moves the needle on a fault dispute, where to find it, and how to use it before it disappears.
And before you give a recorded statement to any insurer, including your own, talk to an attorney. Not because you have anything to hide, but because those calls are structured to gather information in ways that can quietly shift blame. You’re allowed to get your bearings first.
Why the Other Side Will Try to Inflate Your Fault
Insurance adjusters get paid to close claims. The faster and cheaper, the better. When a crash involves any ambiguity around fault, their job is to find your slice of it and make it as large as possible.
Insurance companies are trained to find contributing factors on the claimant’s side, because every percentage point of fault they can assign to you reduces what they owe. A 20% fault finding on a $150,000 claim saves them $30,000. The incentive is enormous.
Fault assignments aren’t final until they’re final. An insurer’s initial determination isn’t a verdict. It can be challenged, renegotiated, and in some cases taken to a jury. Having an attorney who understands how these determinations get made, and how to push back on ones that don’t hold up, is the difference between an insulting first offer and a fair settlement.
What Evidence Determines Fault?
Fault percentages get built from whatever evidence exists, then argued over by attorneys, and either negotiated in a settlement or handed to a jury.
- Photos of vehicle positions, skid marks, road conditions, and sight lines
- The police report and any citations issued at the scene
- Witness statements from anyone who saw what happened
- Dashcam footage from either vehicle
- Medical records, which can reflect the direction and force of the impact
- Phone records, when distracted driving is a factor
And adjusters will look well beyond this list, pulling in things like your speed relative to road conditions, your following distance, and your familiarity with the road.
You don’t have to track all of this down yourself. We know what to look for, where to find it, and how to use it before it disappears.
Common Scenarios Where Fault Gets Contested
Most people who think they were partly at fault weren’t doing anything reckless. They made a normal driving decision that, in hindsight, contributed to what happened. These are the situations we see most often.
You got rear-ended, but you stopped suddenly. The driver behind you will almost certainly be assigned most of the fault. But if you braked hard without much warning, cut over from another lane, or your brake lights weren’t working, expect your percentage to get argued.
You were turning left and got hit. Turning drivers take the blame by default in a lot of these crashes. But default isn’t the same as correct. A driver coming the other way who was well over the speed limit, or who pushed through a light that had already gone yellow, contributed too.
You both entered an intersection and now you have two completely different stories about who had the light. No camera, no witnesses, just your word against theirs. These cases don’t resolve themselves. They get won or lost based on whoever does a better job building the evidence around what actually happened.
You were part of a pileup. The more cars involved, the messier the fault picture gets. Oregon distributes blame across everyone who contributed, and your percentage gets worked out separately from everyone else’s. What looks like an obvious chain reaction on the surface usually has a lot more going on underneath once attorneys start pulling at it.
If your situation isn’t on this list, that doesn’t mean fault isn’t in play. It usually is. The question is always the same: what did each person do, and how much did it matter?
If You’re Partially at Fault, How Does That Affect Your Insurance?
Shared fault doesn’t shut down your insurance options, but it can change how the math works.
Your own PIP coverage pays out regardless of fault. It covers immediate medical expenses and a portion of lost wages while everything else gets sorted out. You can read more about how that works in our Oregon PIP insurance post.
Where things get more complicated is in your claims against other drivers and, potentially, your own insurer.
Your third-party claim against the at-fault driver gets reduced by your fault percentage. Say your damages are $100,000 and you’re 30% at fault. You’re recovering $70,000. If the other driver only carried $50,000 in liability coverage, that leaves a $20,000 gap. Your UM/UIM coverage exists to fill it.
Here’s where people get surprised. Your own UM/UIM insurer steps into the shoes of the at-fault driver, which means they have a financial incentive to fight your fault percentage. A higher fault number shrinks the gap they’re responsible for covering. That’s why UM/UIM claims can get surprisingly contentious, even when you’re dealing with your own insurance company. We cover how that coverage works in more detail in our UM/UIM coverage post.
Regardless, an attorney skilled in personal injury law and good at negotiations can factor these things in and often get you full, or close to full, damages anyway.
Partly at Fault Doesn’t Mean Out of Options
Most crashes involve more than one factor. Oregon law accounts for that, and so do we.
What matters is getting someone in your corner early, before the fault picture gets locked in and before evidence starts to disappear. The insurance industry has a well-worn playbook for these situations. We’ve seen all of it.
