Quick answer

What does Comparative Negligence mean?

A liability framework that reduces recovery when the injured party shares fault. UM/UIM carriers may reserve rights citing comparative negligence even when police reports assign fault. Related: /claims/cases/7; /claims/guides/auto-uninsured-motorist-claim-guide.

How it works

In auto insurance policies, comparative negligence is usually defined in the contract rather than in marketing copy. Read the exact wording, then check whether the term changes your deductible, covered causes of loss, documentation burden, or claim payout.

Example and common mistake

Example

Before choosing a policy, compare how comparative negligence appears in the declarations page, coverage form, and exclusions. Small wording differences can change the claim result.

Common mistake

Do not assume comparative negligence means the same thing across carriers. Confirm the limit, trigger, waiting period, or proof requirements before relying on a quote.
