After a crash in King County

  1. Get the crash report

    Local police departments send requesters to WSP: the Seattle Police page says 'Washington State Patrol is the custodian of all collision reports within the State of Washington. You can request a copy of any collision report through their website,' and for collisions outside Seattle, contact the local agency or search the WSP collision report search.

    How to get a Washington crash report

  2. Know your deadline

    Washington gives you three years to file a personal injury lawsuit (Wash. Rev. Code § 4.16.080(2)). If a city, county or state vehicle was involved: Before suing a city, county or other local government for damages, you must present a claim to its designated agent and wait 60 calendar days; the limitation period is tolled during those 60 days. (The three-year limitation period still applies.)

    Work out your date

  3. Who pays

    Washington is an at-fault state: the driver who caused the crash, through their liability insurance, pays for the injuries and damage.

    Washington car accident laws

  4. If you were partly at fault

    You can recover even if you were mostly at fault; your damages are reduced in proportion to your share of fault and you are never barred outright.

    The rule and its statute

  5. The other driver’s minimum coverage

    The legal minimum liability coverage in Washington is $25,000 per injured person, $50,000 per crash and $10,000 for property (25/50/10).

About these numbers

FARS counts every crash on a public road in which someone died within 30 days. It leaves out the far larger number of crashes that only injured people. Places are as coded in the report: a crash on a county road just outside city limits counts for the county, not the city. Rates use the Census 2024 population estimate and the five-year average.
