Washington requires all drivers to carry minimum liability insurance of 25/50/10 (Bodily Injury per person / Bodily Injury per accident / Property Damage):
Washington enacted legislation in 2024 banning the use of credit scores in auto insurance rate setting, following California as one of the few states to take this step. This regulatory change is reshaping the market as insurers adjust pricing models to comply, which can cause rate shifts for drivers across the credit spectrum. Seattle carries the state's highest rates, driven by heavy traffic congestion, elevated vehicle theft, and increasing claim severity across the Puget Sound metro area.
Washington's rate environment has been under upward pressure from multiple factors beyond the credit score reform: growing population in the Seattle-Tacoma corridor, increasing accident frequency on expanded highway networks, and rising vehicle repair costs from advanced safety technology. Eastern Washington — Spokane and the agricultural regions — offers substantially lower rates than the west side of the Cascades. Washington's wet climate contributes to elevated accident frequency during the extended fall and winter rain season, particularly affecting drivers who move to the state from drier climates.
