What Happens if Insurance Cannot Decide Who Is at Fault
When no one can prove fault, each driver's own insurer decides what share of blame applies to their policyholder, and that share can affect your rate.
Each insurer makes its own fault decision
Insurance companies don't wait for a court to settle the question. Each insurer investigates the crash on its own and decides what percentage of fault its policyholder carries. Your insurer and the other driver's insurer can reach different conclusions, and sometimes neither one assigns full fault to either side.
This matters because your rate doesn't depend on a judge or a police officer agreeing with you. It depends on what your own insurer decides, based on the report, the damage, and whatever statements were given at the scene. If they find you even partly at fault, that can show up on your record and in your renewal price.

Your state's fault rules decide how the split works
Some states use a system where fault can be divided between drivers by percentage, and your insurer pays its share based on that split. Other states use no-fault rules, where your own policy covers your injuries regardless of who caused the crash, and fault mostly matters for property damage or for larger claims that fall outside no-fault coverage.
Which system applies to you changes what an unclear fault finding actually costs you. In a split-fault state, being found even a small percentage responsible can still raise your rate. In a no-fault state, an unclear outcome may matter less for your own injury claim but still affect who pays for vehicle damage.
Your insurer or your state's insurance department can tell you which system applies and how partial fault is calculated there. It's worth asking directly rather than assuming, since the rules vary by state and the difference changes what you should expect next.

What you reported at the scene carries a lot of weight
When fault is genuinely unclear, insurers lean heavily on whatever was documented right after the crash. The police report, if one was filed, your own statement, photos of the damage, and any witness accounts all shape how your insurer sizes up what happened.
If you didn't get a police report or didn't take photos, there may be less to work with, and that can leave more room for your insurer to assign you a share of fault you don't agree with. You can still dispute that finding. Ask your insurer what evidence they used and whether you can submit anything additional, like a witness statement or a repair estimate that supports your account.
It also helps to ask early whether the claim is still open for review. Fault findings are sometimes revised if new information comes in, but that window doesn't stay open indefinitely.
Questions people ask about this
Can I dispute my insurer's fault decision?
Yes, you can ask your insurer to reconsider if you have evidence they didn't use the first time. Call your claims adjuster, ask what the decision was based on, and submit anything new, like photos, witness contact information, or a second police report if one exists. There's no guarantee it changes the outcome, but it's a reasonable step before accepting the finding.
Does a 50/50 fault split affect my rate?
It can, depending on your insurer and your state's rules. Some insurers treat any assigned fault, even a partial share, as grounds for a rate increase at renewal. Others only raise rates above a certain fault threshold. Ask your insurer directly how they handle partial fault findings before you assume what will happen.
What if the other driver's insurer blames me but mine doesn't?
This happens, and it usually means the two insurers negotiate or the claim moves toward arbitration between the companies. Your own insurer represents your side of that discussion. Ask them where the claim stands and whether you need to provide anything further to support your account.
Will an unclear fault accident show up on my driving record?
A fault determination from an insurer is different from a citation or conviction on your driving record. Your state's DMV record generally reflects tickets and violations, not insurance fault findings. But the accident itself, and any claim paid out, can still appear in your insurance history even without a ticket attached.
Should I get a lawyer if fault is disputed?
It depends on what's at stake. For a minor fender bender with only property damage, most people resolve this through the insurers directly. If there are significant injuries, large repair costs, or you believe your insurer is assigning fault unfairly, talking to an attorney who handles auto claims can help you understand your options.
See how an unclear fault finding might affect what you'd pay with a different insurer.

Call your claims adjuster and ask exactly what evidence they used to assign fault, and whether the claim is still open to review. Gather anything you haven't already submitted, including photos, repair estimates, or witness contact information, and send it in writing. Ask specifically how this finding will affect your renewal, since not every insurer treats partial fault the same way. If you disagree with the outcome, ask what your options are for appeal before the claim closes. Once you know how your current insurer plans to treat this, it's worth comparing what other insurers would charge given the same record.
