Seattle car insurance: PIP, underinsured motorist cover and local risks

What Washington requires on a Seattle policy

Washington is an at-fault state: the driver who causes a crash is responsible for the harm, and their liability insurance pays. On top of that, state law builds two protections into every policy unless you turn them down in writing.

PIP pays your own medical costs and some other losses after a crash, whoever was at fault. Washington's rule: Must be offered; can be rejected in writing (basic PIP pays up to $10,000 per person for medical costs). See our PIP guide.

Underinsured motorist coverage in Washington does more than its name suggests. It also pays when the at-fault driver has no insurance at all or cannot be found, as in a hit-and-run. With 19.1% of Washington drivers estimated to be uninsured in 2023, compared with 15.4% nationally, rejecting it removes a real layer of protection. See uninsured motorist coverage and hit-and-run claims. The Washington guide has the full statewide rules.

Getting around Seattle, with or without a car

Seattle had 784,777 residents in 2025. Commuters spend an average of 26.0 minutes getting to work, and 19.0% of households, or 68,926, have no vehicle.

That car-free share matters. If you do not own a car but use car-share vehicles, rentals or a friend's car, non-owner car insurance adds liability coverage that follows you. If you own a car but drive little, ask insurers about low-mileage or telematics pricing.

The city runs a Vision Zero program aimed at ending traffic deaths and serious injuries on Seattle streets. Statewide, Washington recorded 730 crash deaths in 2024, or 9.2 per 100,000 people. IIHS estimates that 33% of passenger vehicle drivers killed had a blood alcohol level at or above the legal limit, and speeding played a part in 34% of deaths.

Theft, location and your Seattle premium

Insurers set prices by where a car is garaged, using the claims history of each rating territory. The NAIC notes that urban areas generate more claims than rural ones and that repair costs run higher in populated areas. Our guide on how ZIP codes affect car insurance explains the details.

Vehicle theft is a big part of the Seattle picture:

• The Seattle-Tacoma-Bellevue, WA metro area recorded 12,684 thefts in 2025, the No. 10 total among US metro areas.
• Washington as a whole had 18,039 thefts, the No. 9 total among states.
• Yet Washington's thefts fell 39% from the year before, or 11,617 fewer cars, the largest percentage drop on NICB's list of states.

A stolen car is covered only by comprehensive coverage, minus your deductible. Liability, PIP and underinsured motorist coverage do not pay for it. If it happens, see what to do if your car is stolen.

Ways to pay less in Seattle

1. Compare quotes for the same coverage. Give each insurer the same limits and deductibles so the prices line up. See shopping at renewal.
2. Weigh PIP and underinsured motorist coverage carefully. Rejecting either lowers the premium but removes protection; know what your health insurance would pay first.
3. Choose deductibles you can afford. A higher deductible lowers collision and comprehensive costs.
4. Ask about every discount. Our discounts guide lists the common ones.
5. Get help when needed. The Washington State Office of the Insurance Commissioner answers consumer questions at 800-562-6900 (Consumer Advocacy).
