Washington Personal Lines Law & Coverage Rules
This chapter covers the Washington-specific personal lines rules that sit on top of the shared national property & casualty fundamentals: who regulates insurance in Washington, the minimum auto liability limits, the state's tort (at-fault) system and optional Personal Injury Protection, and the notice rules governing cancellation and nonrenewal. Figures below were checked against the Washington Office of the Insurance Commissioner this session; always confirm current numbers before advising a client.
The Washington Office of the Insurance Commissioner
Insurance in Washington is regulated by the Office of the Insurance Commissioner (OIC). Unusually, Washington's Insurance Commissioner is a statewide elected official rather than a gubernatorial appointee. The OIC licenses producers and companies, reviews policy forms and rates, investigates complaints, and enforces the insurance code. There is no federal insurance department.

Minimum Auto Liability Limits (25/50/10)
To satisfy Washington's financial-responsibility law, a personal auto policy must carry at least $25,000 bodily injury per person, $50,000 bodily injury per accident, and $10,000 property damage (written 25/50/10). These are minimums — producers should offer higher limits, especially for property damage given modern vehicle values. Verify current figures with the Washington Office of the Insurance Commissioner.
Tort System and Optional PIP
Washington is a tort (at-fault) state: the driver who causes a crash is financially responsible for the other party's injuries and property damage. Washington is not a no-fault state, but insurers must offer Personal Injury Protection (PIP) — no-fault coverage for the insured's own medical costs, lost wages, and related expenses regardless of fault. PIP is optional: the named insured may reject it in writing. Uninsured/underinsured motorist coverage must also be offered. Confirm current minimum PIP and UM amounts with the OIC.
Cancellation and Nonrenewal
State law limits the reasons an insurer may cancel a personal auto or homeowners policy mid-term (for example nonpayment or material misrepresentation) and requires advance written notice of cancellation or nonrenewal. The exact number of days depends on the reason and line — verify current Washington notice periods with the Office of the Insurance Commissioner rather than memorizing a single number.
