What if I was partly at fault?

A lot of people assume that if they contributed to an accident at all, they have no claim. In California that is wrong. You can be partly at fault and still recover — your share just comes off the top.

It is general information, not legal advice, and it does not tell you whether you have a case.

The short answer

California uses pure comparative fault. A jury assigns each person a percentage of the fault, and you recover the total damages minus your percentage. There is no cutoff. If you are found 40 percent at fault, you recover 60 percent. If you are found 75 percent at fault, you still recover 25 percent. The doctrine and the multi-defendant math are on comparative fault.

Situations where this comes up

• You were speeding a little. Going a few miles over does not excuse a driver who turned left across your path, but a jury may assign you a small share.
• You crossed outside a crosswalk. A pedestrian outside a crosswalk has to yield, but the driver still owes a duty of due care. The result is usually a split, not a bar.
• You did not see it coming. An insurer will argue you could have avoided the crash. Whether a reasonable person in your position could have is a jury question.
• You were not wearing a seat belt or a helmet. This can reduce the damages for injuries the equipment would have prevented, if the defense proves that link — but only those injuries, and only with medical proof.
• You had been drinking. If you were a passenger, this rarely matters. If you were driving, it is a serious fault and coverage issue — see why firms say no.

What the adjuster is doing

The other driver's insurer benefits from every percentage point of fault it can pin on you, because that reduces what it pays. So an adjuster will often state early and confidently that you were "50-50" or "mostly at fault." That is a negotiating position. It is not backed by a neutral finding, and it can be moved with:

• the traffic collision report and any citation,
• the physical damage and a reconstruction,
• independent witnesses,
• the specific Vehicle Code rule the other driver broke.

What to say — and not say

• Do give an accurate, factual account: where you were, what you saw, what you did.
• Don't volunteer a conclusion about fault. "It was my fault" or "I should have seen him" is an opinion on a legal question, and it gets used against you.
• Don't guess at speeds, distances, or times. "I don't know" is a complete answer.
• Don't give a recorded statement to the other driver's insurer before getting advice — see recorded statements.

Common questions

Can I still sue if the accident was partly my fault?

Yes. California uses pure comparative fault. Your recovery is reduced by your percentage of fault, but the claim is not barred, no matter how high that percentage is.

The adjuster told me I was at fault. Is that final?

No. An adjuster's opinion is a negotiating position, not a ruling. Fault is decided by a jury if the case is tried, and the adjuster's number can be pushed back with the police report, the physical evidence, witnesses, and the traffic law.

Does not wearing a seat belt hurt my claim?

It can. If the defense proves that a seat belt would have prevented or reduced specific injuries, a jury can reduce those damages. It does not bar the claim and has no effect on injuries a belt would not have changed.

Should I admit fault to be honest?

Give an accurate account of the facts, but do not volunteer conclusions about fault, guess at speeds or distances, or apologize in a way that sounds like an admission. Fault is a legal conclusion drawn from the facts — leave that to be worked out.
