Being partly at fault does not end your claim in California. The state follows pure comparative negligence, which means your recovery is reduced by your percentage of fault and nothing more. If your damages are $100,000 and you were 30 percent at fault, you recover $70,000. If you were 60 percent at fault, you still recover $40,000. There is no cutoff where a partly at fault driver is barred, which sets California apart from many states.
What decides these cases is who assigns the percentage and what they base it on. Before a lawsuit, the percentage is whatever the adjuster says it is, and adjusters assign fault to claimants reflexively because every point they shift to you is a discount on the claim. A 50/50 split is the default offer whenever liability is less than obvious. After a lawsuit, the percentage belongs to a jury, and juries decide it on evidence: the physical damage, the vehicle data, the cameras, the witness testimony. The gap between the adjuster’s number and the evidence’s number is usually where the case is won or lost, and that gap is often 20 to 40 points.
Can I still recover if I was partly at fault for the accident?
Yes. California applies pure comparative negligence. Your damages are calculated in full and then reduced by your share of fault, whatever that share is. A driver found 25 percent at fault recovers 75 percent of their damages, and a driver found 75 percent at fault still recovers 25 percent. The percentage is decided by the evidence, not by the police report or the insurer’s opening position, and it is negotiated in nearly every contested case.
How comparative fault works in California
California adopted pure comparative negligence by court decision in 1975 and has applied it since. The jury instruction on it asks the jury to find each party’s percentage of responsibility, with the total adding to 100, and the judge reduces the plaintiff’s award accordingly. The concept applies to every injury case, not only car crashes: a fall in a Costco parking lot where you were looking at your phone, a pedestrian crossing Ventura Blvd mid-block, a motorcyclist splitting lanes faster than conditions allowed.
Two related rules come up often. First, when more than one defendant is at fault, each is responsible for the full amount of your economic damages (medical bills, lost wages), but only for their own share of non-economic damages (pain and suffering) under Civil Code 1431.2. Second, if you were driving your own uninsured car, Civil Code 3333.4 bars your pain and suffering recovery regardless of fault, so an uninsured driver who was partly at fault is in a difficult spot even though the other driver caused most of the crash.
Fault also cuts the other way. If you were partly at fault, the other driver can claim against you, and your liability coverage responds. That is one reason not to carry only the $30,000 minimum.
What the insurance company will argue
The adjuster will look for any fact that supports putting fault on you. A ticket issued to you at the scene. A statement that you “didn’t see” the other car. Speed. A phone in use. A left turn, because the turning driver is presumed at fault in most left turn crashes unless the oncoming driver was speeding or ran a red. Not wearing a seatbelt, which can be raised as comparative fault for injuries the belt would have prevented, though it does not bar the claim.
Here is an example. A Chatsworth client made a left turn from Devonshire onto Topanga Canyon on a green arrow that had just turned yellow and was hit by an oncoming pickup. The adjuster assigned her 70 percent fault based on the turn alone. The intersection camera from a nearby auto parts store showed the pickup entering the intersection well after the light had gone red, at a speed that put it at roughly 50 miles per hour in a 40 zone. The adjuster’s number was wrong by at least 50 points, and the file settled on a liability split that reflected the video, not the presumption.
The adjuster’s percentage is an opening position. Treat it like one.
What to do now
Don’t admit fault to anyone, including the other driver, the officer, or an adjuster. You don’t know what the other driver was doing, and “I think it was my fault” is a statement you cannot take back. State facts: where you were, what you saw, what happened. Don’t estimate your speed or the distance unless you actually know it.
Then gather the evidence that decides percentages. Photos of both vehicles where they came to rest and of the damage from several angles. Names and numbers of witnesses. Cameras at businesses, apartment buildings and intersections, requested in writing right away because the video is overwritten in days. Your own dashcam. The other vehicle’s event data recorder, which stores speed, braking and throttle for the seconds before impact and can be preserved by letter before the car is repaired or scrapped. Each of these moves the number.
Keep your treatment consistent, because your damages still have to be proven in full before any reduction is applied. A reduced percentage of a well documented claim is worth more than a full percentage of a thin one.
Common mistakes
The first is accepting the adjuster’s percentage as a finding. It is a negotiating position. The second is assuming a citation settles fault. A ticket is an officer’s opinion, usually formed without seeing the crash, and the officer’s opinion on fault is generally not admissible at trial. The third is apologizing in a recorded statement. The fourth is letting the car get repaired or totaled before the damage is photographed and the data pulled. The fifth is walking away from a claim entirely because you think “it was partly my fault” means no case. In California it means a smaller case, and sometimes not by much.
Questions people ask next
What if the police report says I was at fault? The report is not binding and the officer’s conclusion is usually inadmissible. Fault is decided on evidence.
Does being partly at fault reduce my medical bills claim too? Yes. The percentage applies to all of your damages, economic and non-economic alike.
Can I still use my uninsured motorist coverage if I was partly at fault? Yes. UM and UIM claims are also subject to comparative fault, and the percentage is negotiated with your own insurer.
