Is Washington an At-Fault or No-Fault State?

No — Washington is an at-fault (tort) state, not a no-fault state.

Fault system
At-fault (tort)

The driver responsible for a crash, and their insurer, pays for the resulting damage. PIP is optional coverage in Washington, not a no-fault substitute for a liability claim.

Comparative negligence rule
Pure comparative

A claimant's own fault reduces the award proportionately but does not bar recovery, even when the claimant is mostly at fault (RCW 4.22.005).

PIP minimum limit
$10,000

Medical and hospital benefit in the minimum PIP package insurers must offer (RCW 48.22.095). PIP can be rejected in writing.

How Washington compares with every other state

What the fault rule decides

In an at-fault state the driver who caused the crash — through their liability insurer — pays for the harm. That is the arrangement in 38 of the 51 jurisdictions on this site, so it is the one most US advice assumes. The practical consequence is that your recovery depends on two things you do not control: how much liability cover the other driver bought, and what share of the blame you are assigned.

Pure comparative fault has no cliff. Your damages are cut by your share of the blame and nothing more: on a hypothetical $100,000, a driver 80% at fault still recovers $20,000. 9 of the 50 jurisdictions on this site work this way. It is the most forgiving arrangement for a driver who was mostly but not entirely in the wrong, and the reason a claim worth little in a neighboring state can still be worth bringing here.

The $10,000 of personal injury protection is the money that moves first, before anyone argues about blame — and it is higher than 7 and lower than 7 of the 18 that require it. Treat it as a floor rather than a budget: it is what the state makes you carry, not an estimate of what an injury costs.
