Quick answer
Comparative negligence is a rule that splits the blame for a crash among the people involved and cuts each person's recovery by their own share of fault. If you are found 20% at fault, you can recover 80% of your proven damages, as long as your state's rule does not bar the claim.
In a car accident claim#
Most states use some form of comparative negligence, but the versions differ. Under pure comparative fault, used in 9 jurisdictions, you recover your damages minus your share of fault, even if you were mostly to blame. Under Modified comparative fault. Comparative negligence with a cut-off: once your share of blame reaches the state's bar (50% or 51%), you recover nothing. Glossary, you lose the claim once your share reaches a bar: 51% in 26 jurisdictions, including Texas, and 50% in 10. A few places still follow the older Contributory negligence. An older rule, still used in a few places, under which any fault of your own can bar you from recovering anything. Glossary rule.
Fault shares matter long before any trial. Insurers use them in negotiation, so evidence that you were speeding, distracted or missed a signal can cut an offer. The fault-rule explainer shows how each state treats a given share, the car accidents guide explains how fault is proven, and our state guides list each state's rule.

Questions people ask
What is the difference between pure and modified comparative negligence?
Under a pure rule, you can recover something at any share of fault below 100%. Under a modified rule, you recover nothing once your share reaches the state's bar, either 50% or 51%.
Who decides each driver's percentage of fault?
During negotiation, each insurer forms its own view, and the two sides bargain over it. If the case goes to trial, a jury or judge decides the percentages.
