- Washington averages around $2,312/year — Seattle drives the state average well above rural eastern Washington
- Rates rose +35% since 2023 — Seattle congestion and population growth are the primary drivers
- PEMCO Insurance is the Pacific Northwest's top regional carrier — mutual ownership, high satisfaction, competitive pricing
- Greater Seattle metro runs 40–60% above eastern Washington and rural areas for the same driver profile
- Washington's growing population and traffic volume create structural cost pressure that is likely to persist
Washington state averages $2,480 per year for full coverage — modestly above the national average and trending upward. Seattle and its suburbs are the primary cost center: traffic on I-5, I-405, and SR-520 is among the worst in the country, and the region's high income levels mean more expensive vehicles on the road and higher repair bills when accidents occur.
Washington is a tort-based state, so at-fault drivers bear full liability. The state's uninsured motorist rate has been rising, adding cost pressure across all insured drivers. Eastern Washington — Spokane and the Tri-Cities — is significantly more affordable than the Puget Sound region, often running 30–40% lower than Seattle metro rates.

What are Washington's minimum auto insurance requirements?
Washington requires 25/50/10 liability coverage — $25,000 per person / $50,000 per accident bodily injury and $10,000 property damage. Washington is a tort state. Washington prohibits the use of credit history in auto insurance pricing — one of the strongest such bans in the country — meaning your credit score cannot raise or lower your premium.
How does Washington's credit scoring ban affect rates?
Washington's ban on credit-based insurance scoring means carriers price based on driving record, vehicle, location, and other non-credit factors. If you have excellent credit, you lose the discount you'd receive in other states. If you have poor credit, it won't raise your premium. Washington's ban is one of the most comprehensive in the country — it applies to all rating and underwriting decisions.
Is PEMCO only available in Washington?
PEMCO operates primarily in Washington and Oregon. In Washington, PEMCO is employee-owned (mutual structure), does not sell through brokers, and consistently earns the highest loyalty scores of any carrier in the state. PEMCO is available directly at pemco.com. For Washington drivers, getting a PEMCO quote alongside State Farm and GEICO is strongly recommended — the pricing and service record is hard to match regionally.
