No-fault state

Collision Bureau is not a law firm and this is not legal or medical advice. It is general information about what happens after a crash. For advice on your situation, talk to an attorney licensed in your state or a treating clinician.

What it means

No-fault state is shorthand for a state whose auto insurance system directs each driver's own insurer to pay a defined set of post-crash costs first, without a fault determination. The point of the design is speed on the small and mid-size cost categories, like initial medical bills and lost wages, which get paid off the injured person's own policy before anyone argues about who caused the crash. The word no-fault describes the payment path, not a conclusion that nobody was responsible.

How the design works in general terms

Three features define the model. First, a required first-party coverage, usually personal injury protection, that pays regardless of fault up to a policy limit. Second, limits on when an injured person can sue the other driver, often tied to a threshold that measures the seriousness of the injury. Third, interaction rules that decide how the first-party payment coordinates with health insurance, workers' compensation, and any claim against the at-fault driver. The specifics are set by each state's statute and vary significantly in dollar amounts and in wording.

Where it comes up in a crash

If a crash happens in a no-fault jurisdiction, the first instinct in the paperwork is to open a claim with the injured person's own insurer under the required first-party coverage, not with the at-fault driver's insurer. Medical bills route through that policy up to its limit. Property damage usually remains fault-based and is handled through the at-fault driver's property damage liability coverage, which is a separate conversation. A claim large enough to clear the injury threshold can also carry a traditional claim against the other driver, running in parallel.

What it is not

A no-fault state is not a place where fault stops mattering. The fault question is still there, it is just handled on a different track than the first-party payment. The term is not synonymous with any specific statute or coverage amount, because the systems in different states have real differences in their thresholds, their limits, and their lawsuit rules. And it is not a label this page can apply to any specific place: which states use which model changes with legislation. For a specific crash in a specific location, an attorney licensed in that state is the right source for whether a no-fault rule applies and how it applies.
