Can You Still Recover if the Crash Was Partly Your Fault?

Being partly at fault for a crash does not end a California injury claim. California follows pure comparative negligence, which reduces what you collect by your share of the blame and never bars the claim outright. There is no percentage at which the door closes.

The more useful point gets lost in most explanations. The other driver’s insurance company does not get to assign your percentage. Fault sharing is a defense, and the party raising it carries the burden of proving it. That is the first thing an Orange County personal injury lawyer checks, and it is where the Law Offices of William W. Bruzzo starts on a disputed-fault file.

How Does Partial Fault Affect a California Injury Claim?

Partial fault in a California crash reduces damages in proportion to the share of negligence assigned to the injured person. The rule comes from the California Supreme Court’s 1975 decision in Li v. Yellow Cab Co., which replaced the old all-or-nothing bar with a system whose purpose is “to assign responsibility and liability for damage in direct proportion to the amount of negligence of each of the parties.”

The arithmetic is simple once the numbers are set.

• Damages of $100,000 with the injured driver 20 percent at fault produce a recovery of $80,000.
• The same damages with the injured driver 50 percent at fault produce $50,000.
• The same damages at 90 percent fault still produce $10,000.

That last line is what pure comparative negligence means in practice. A serious share of blame shrinks the case. It does not delete it.

Why California Has No Fault Cutoff

California sets no fault threshold, while many other states cut recovery off at one. In Texas, a claimant “may not recover damages if his percentage of responsibility is greater than 50 percent.” Nevada bars recovery once the claimant’s negligence is greater than that of the parties being sued, which matters for Orange County residents hurt on a drive to Las Vegas.

California rejected that approach deliberately. No California statute adopts comparative negligence at all. It is judge-made law from Li, and the same decision confirmed that Civil Code § 1714, often cited as the source, never codified contributory negligence as an absolute bar.

Who Has to Prove You Were Partly at Fault?

Comparative fault is an affirmative defense, which means the defendant has to prove it. The Judicial Council civil jury instruction on comparative fault of a plaintiff, CACI 405, tells the jury that the defendant “must prove both of the following,” that the plaintiff was negligent and that the plaintiff’s negligence was a substantial factor in causing the harm.

Nothing in that instruction asks the injured person to disprove fault. An adjuster’s early letter announcing that you were 40 percent responsible is an opening position in a negotiation, not a finding, and it is often built on a partial statement taken days after a collision.

How Is Your Percentage Actually Decided?

A jury sets the fault percentage in a California injury trial, and it does so in two separate steps. CACI 406 directs the jury to assign percentages of responsibility that total 100 percent, and then adds this about valuing the case, “In determining an amount of damages, you should not consider any person’s assigned percentage of responsibility.”

Damages get valued first, in full, with fault set aside. The reduction comes afterward, and the judge applies it. CACI 405 tells jurors plainly, “I will calculate the actual reduction.”

That sequence answers the fear behind the question. Partial fault does not make the injury count for less. It changes what gets collected at the end, after the harm has already been measured on its own terms.

Does Not Wearing a Seat Belt Make It Your Fault?

Failing to wear a seat belt is not automatic fault in California. Vehicle Code § 27315(i) states that a violation of the belt requirements “does not establish negligence as a matter of law or negligence per se for comparative fault purposes, but negligence may be proven as a fact without regard to the violation.”

Raising belt use as a defense puts four things on the defendant. A working belt was available, a reasonably careful person in the same situation would have used it, the injured person did not, and the injuries would have been avoided or less severe with it. That last element usually calls for medical or biomechanical testimony, and it is where the defense most often falls apart.

The safety numbers still matter to how these cases are argued. The California Office of Traffic Safety reports 780 unrestrained occupant fatalities statewide in 2023, down from 853 the year before.

What If More Than One Driver Was at Fault?

Crashes with more than one at-fault driver split the analysis in California. Economic losses such as medical bills and lost earnings remain collectible in full from any one negligent defendant, reduced only by the injured person’s own share. Non-economic damages work differently, because Civil Code § 1431.2 makes each defendant’s liability for those “several only” rather than joint.

The practical effect shows up when one defendant has no coverage. The pain and suffering attributable to that uninsured defendant is not collectible from the others, which is why the percentages get fought over so hard. Apportionment across several drivers gets more complicated again in a chain reaction, and the way liability divides in a multi-vehicle pileup on the I-5 follows the same rules applied across more parties.

How Long Do You Have to File if You Were Partly at Fault?

The filing deadline does not change because fault is disputed. Code of Civil Procedure § 335.1 allows two years from the date of injury for a personal injury action, and a percentage argument with an adjuster does not pause that clock.

Waiting is the real risk. Evidence that would settle a percentage dispute, including vehicle data, camera footage and independent witnesses, goes stale within weeks, and starting early also shortens the timeline of an Orange County injury case.

Partly at Fault in an Orange County Crash? Have an Attorney Read the File

A disputed fault percentage is a number to be tested against the evidence, not accepted from a claims letter. The Law Offices of William W. Bruzzo handles Orange County collision claims where the other side has already decided who was responsible, and Will Bruzzo has spent more than 30 years testing those conclusions, including service as a Judge Advocate in the United States Marine Corps.
