California's pure comparative fault system means your traffic accident payout decreases by your fault percentage but is never barred outright. Dash-cam recordings and signal-violation citations directly influence how that percentage is set during negotiations.
How Pure Comparative Fault Works in Traffic Accident Cases
California uses pure comparative fault, which means your traffic accident damages decrease in direct proportion to your assigned blame but are never barred outright. A driver found forty percent at fault still collects sixty percent of the total damages. The rule applies regardless of how high your share of fault goes.
The practical result for traffic accident cases is that fault evidence controls the size of the check, not your eligibility to collect one. Police-report narratives, intersection-camera footage, and traffic citations collectively establish the percentage that each driver's award is multiplied against. Building and defending that evidence is the most consequential work in the entire claim.
Reducing Your Fault Percentage With Police and Camera Evidence
In a pure comparative system, every percentage point of fault you can remove from your share increases your payout. Start with the police report: review the officer's narrative for any language that implies shared blame, and prepare a supplemental statement if the facts support a correction.
Traffic-camera footage is a powerful tool in these states because it provides an objective timestamp and visual record that can override conflicting driver accounts. Request it from the municipal traffic department and from any businesses with cameras facing the intersection. Pair that footage with your own photographs of signal positions, lane markings, and vehicle damage. Together, these records form the foundation for arguing a lower fault percentage during negotiations.
A worked example with California’s rule applied
Take a traffic accident claim with documented losses like these:
| Medical bills | $11,700 |
| Lost wages | $3,400 |
| Other out-of-pocket costs | $650 |
| Pain and suffering (2.5× medical) | $29,250 |
| Gross value before fault | $45,000 |
Now apply California’s pure comparative rule. Say the insurer pins 60% of the fault on you: the claim is reduced by $27,000 to $18,000 — but it survives. Even a driver found 60% at fault still recovers the remaining share here, which is exactly why adjusters in pure-comparative states argue percentages rather than trying to kill the claim outright.
How Police Reports and Camera Evidence Shape the Fault Dispute
In a California traffic accident claim, two pieces of evidence carry disproportionate weight: the police report and any camera recordings of the collision. The report documents the officer's on-scene findings — signal compliance, speed estimates, witness accounts, and contributing factors assigned to each driver. Its conclusions shape the insurer's initial liability position and anchor the fault percentage used to calculate your recovery.
Camera footage provides a second, objective account. Traffic-management cameras, red-light enforcement cameras, and nearby business surveillance systems may have captured the collision from angles the officer could not observe. When this footage aligns with the police report, the fault question is effectively resolved. When it contradicts the report, it creates an opportunity to correct the record and present a stronger claim.

Questions
California questions
If I was mostly at fault for a traffic accident in California, can I still recover damages?
California applies pure comparative fault, which allows recovery at any fault level. If your share of blame is seventy percent, you still collect thirty percent of the total damages. Police reports and camera footage are used to establish the exact percentage, and each point directly affects your payout.
How does the police report affect my fault percentage in a California traffic accident claim?
The police report provides the initial fault framework that the insurer works from. The officer's narrative, diagram, and any citations establish a preliminary allocation of blame. If the report contains inaccuracies, you can file a supplemental statement. Camera footage and witness testimony can further adjust the percentage during negotiations.
Does California's pure comparative fault rule apply to all traffic accident claims?
Pure comparative fault generally applies to all negligence-based traffic accident claims in California. It governs how damages are allocated when both drivers share blame. Government-entity claims may have separate procedural requirements including shorter notice deadlines, so check those timelines immediately if a public vehicle or road-maintenance issue was involved.
