Car Insurance in Washington

State minimum coverage requirements

Under Revised Code of Washington 46.29.090, all Washington drivers must maintain the following minimum coverage:

• $25,000 bodily injury per person
• $50,000 bodily injury per accident
• $10,000 property damage per accident

Driving without insurance in Washington results in a fine of up to $550 and can result in license suspension. You must carry proof of insurance at all times and present it upon request by law enforcement or after an accident. Washington requires SR-22 filing after certain violations including DUI convictions, driving without insurance, and reckless driving. The $10,000 property damage minimum is particularly low relative to the cost of vehicle repairs, especially in the Seattle market where newer and more expensive vehicles are common. Washington also permits electronic proof of insurance displayed on a smartphone, which is accepted in lieu of a paper card.

Is Washington a no-fault state?

No. Washington is an at-fault state.

Washington is an at-fault state, meaning the driver responsible for causing an accident is liable for the resulting damages. Injured parties file claims against the at-fault driver's liability insurance rather than their own policy. Washington applies a pure comparative fault rule, which means you can recover compensation from another driver even if you were partially or even predominantly at fault, though your recovery is reduced proportionally by your share of fault. If you were 60 percent at fault for an accident that caused you $80,000 in damages, you could still recover $32,000 from the other driver. This rule also means that if you cause an accident and the other driver contributed partially to it, they can still recover the portion of their damages attributable to your fault from your liability coverage. The $10,000 property damage minimum is easily exceeded in an accident involving a newer vehicle, making higher property damage limits a practical necessity for most Washington drivers.

What the state minimum covers and does not cover

Washington's 25/50/10 liability minimum covers only injuries and property damage you cause to other people. It does not cover:

• Damage to your own vehicle from a collision
• Your own medical expenses after an accident
• Losses caused by an uninsured or underinsured driver
• Theft, weather events, or vandalism to your vehicle

Uninsured motorist coverage is mandatory

Washington requires all auto insurance policies to include uninsured motorist coverage at limits matching the policyholder's liability coverage unless the driver specifically rejects it in writing. This mandatory offer at matching limits means that if you carry 100/300 liability, your insurer must include 100/300 UM coverage by default. Washington also requires underinsured motorist coverage to be offered, and the two coverages together provide meaningful protection in a state where some drivers carry only the minimum. UM coverage pays for your medical expenses and vehicle damage when an at-fault driver has no insurance. UIM coverage fills the gap when an at-fault driver's policy is insufficient to cover your actual losses. Washington's relatively high cost of medical care in the Seattle metro area makes both coverages especially valuable.

How credit affects your rate in Washington

Washington permits insurers to use credit-based insurance scores as one factor in pricing auto policies. The check is a soft inquiry and does not affect your credit report or score. Washington has debated restricting credit-based pricing in recent legislative sessions, so the rules in this area may change. As of the current policy year, credit remains a permitted rating factor for most carriers in Washington. If your credit has improved since your last renewal, shopping new quotes across multiple carriers is worthwhile because the pricing impact of a better credit profile can be meaningful.

Recommended coverage levels

Most advisors recommend carrying at least 100/300/100 liability in Washington. The $10,000 property damage minimum is especially insufficient given the cost of vehicles in the Seattle market. If your vehicle is financed or leased, collision and comprehensive are required by your lender. Washington's climate, particularly west of the Cascades, brings significant rainfall and road conditions that increase accident risk, and comprehensive coverage is relevant for weather-related damage and the vehicle theft rates that are above average in the Seattle metro area. Because Washington's mandatory UM must match your liability limits by default, raising your liability coverage automatically improves your UM protection as well.

How insurers determine your rate in Washington

Washington insurers use your driving record, zip code, vehicle type, age, annual mileage, and credit-based insurance score to calculate your premium. The Seattle metro area, including King, Pierce, and Snohomish counties, produces higher premiums than eastern Washington and rural areas of the state due to accident frequency, vehicle theft rates, and the cost of medical care and vehicle repairs in urban markets. Washington's tech-industry economy has brought a high concentration of expensive vehicles to the Seattle area, which affects collision and comprehensive pricing. At-fault accidents and moving violations typically affect your rate for three to five years. Comparison shopping across multiple carriers at renewal is the most reliable way to manage your premium over time.

SR-22 requirements in Washington

An SR-22 in Washington is a certificate filed by your insurer with the Department of Licensing confirming you carry at least the state minimum liability coverage. You may be required to maintain an SR-22 after a DUI conviction, after driving without insurance, or after certain serious traffic violations. The requirement typically lasts three years from the triggering event, and your license remains suspended until the SR-22 is on file. If your policy lapses during the SR-22 period, your insurer must notify the Department of Licensing immediately, which reinstates your suspension. Not all insurers handle SR-22 filings, so drivers who need one should specifically look for carriers that serve the non-standard auto insurance market in Washington.
