Five Fault Categories That Govern Traffic Accident Claims
The fifty states and the District of Columbia sort into five fault systems. Contributory negligence states bar your entire traffic accident claim if you carry any fault at all. Pure comparative fault states reduce your recovery by your fault share but never eliminate it. Modified 50% threshold states block recovery once your fault reaches half. Modified 51% threshold states block recovery only when your fault passes the majority mark. South Dakota stands alone with a slight-versus-gross standard that demands your negligence be minor compared to the other driver's serious misconduct.
The practical difference is enormous. The same intersection collision, the same injuries, and the same police report can produce full compensation in one state and nothing in another. Identifying your state's category before entering negotiations tells you whether you need to prove zero fault, minimize a percentage, or stay below a specific threshold.
How Police Reports and Camera Footage Interact With Fault Rules
Police reports and traffic-camera footage are central evidence in every traffic accident claim, but their strategic role shifts with the fault rule. In a contributory-negligence state, a police report that attributes even minor blame to you can eliminate the entire claim — making review and correction urgent. In a pure comparative state, the same report adjusts a percentage rather than creating a binary outcome, though each point still carries a direct dollar value.
Traffic-camera footage, dash-cam recordings, and private surveillance from nearby businesses provide objective evidence that can confirm or challenge the officer's conclusions. Preserving these recordings quickly matters everywhere, but the stakes of losing them are highest where the fault standard is strictest. The pages below explain how your state's specific rule interacts with the evidence that police reports and cameras produce.

Questions
Fault-rule questions
Can I recover at exactly fifty percent fault in a your state traffic accident case?
Yes. your state's rule bars recovery only when your fault exceeds fifty percent. At exactly fifty percent, you can still recover — though your damages are reduced by half. This one-point difference from stricter rules can preserve claims that would otherwise be barred in a neighboring state.
If I was mostly at fault for a traffic accident in your state, can I still recover damages?
your state 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.
What happens to my traffic accident claim if the insurer proves I was partly at fault in your state?
Under your state's contributory negligence rule, any fault on your part eliminates the claim entirely. There is no partial recovery. The insurer does not need to prove you were mostly at fault — even a minor traffic-law violation on your side can bar your right to compensation. Obtaining legal guidance early is strongly recommended.
