Comparative Negligence
Comparative negligence is the legal rule that reduces how much you can recover after a crash by your own percentage of fault. If you were 30% to blame, your payout drops by 30%, and in some states, being too much at fault means you get nothing.
Actuarial & Contractual Mechanics
Most crashes aren't 100% one driver's fault, so insurers and courts assign percentages. States use one of four systems (Bloomberg Law chart). Pure comparative: you recover something at any fault level, reduced by your share. California and New York use it. See is California a no-fault state. Modified, 51% bar: you recover nothing at 51% or more. Texas uses it, as explained in is Texas a no-fault state. Modified, 50% bar: you recover nothing at 50% or more. Georgia and Colorado use versions of it. See is Georgia a no-fault state and is Colorado a no-fault state. Contributory negligence: a handful of jurisdictions bar recovery if you're even 1% at fault. These rules matter most in at-fault states and in no-fault-state lawsuits that pass the tort threshold. The full picture is in our no-fault vs at-fault car insurance states hub.
Sam is hurt when another driver runs a stop sign, but Sam was speeding. His damages total $50,000, and fault is split 60% to the other driver and 40% to Sam. In California (pure), Sam recovers 60%, which is $30,000. In Texas (51% bar), he also recovers $30,000, because 40% is below the bar. Now flip it: if Sam were 55% at fault, California would still pay him 45% ($22,500), while Texas, Georgia and Colorado would pay him nothing.
A few percentage points can be the difference between a fair settlement and nothing, especially near the 50% and 51% bars. Insurers build fault percentages from police reports, photos, witnesses and your own words. Don't guess, apologise or speculate on a recorded call. Read can I refuse a recorded statement to an insurance company, and consider when to hire an insurance lawyer if the insurer's split seems unfair.
Comparative Negligence and Your Own Coverage
Fault splits affect what you recover from the other driver, not what your own first-party coverage pays. Your PIP or MedPay, and your own collision coverage minus the deductible, pay regardless of fault. That's why fault-free coverage matters in at-fault states. See PIP vs MedPay.
