Washington car insurance requirements and laws

Minimum car insurance requirements

Washington's mandatory insurance law, enforced by the Department of Licensing, requires anyone driving in the state to carry liability insurance at the levels in RCW 46.29.090 and 46.29.490. Alternatives are a certificate of deposit with the Department of Licensing, a $60,000 surety bond, or self-insurance for owners of 26 or more vehicles. Since 2019 the requirement also applies to motorcycles. Mopeds, horseless carriages over 40 years old and government vehicles are exempt.

PIP offers must meet the minimums in RCW 48.22.095:

• $10,000 for medical and hospital costs
• $2,000 for funeral expenses
• $10,000 in income continuation, up to $200 a week
• $5,000 for loss of services, up to $200 a week

A rejection covers all levels of PIP and carries over to renewals. Underinsured motorist coverage, which in Washington includes uninsured drivers, must be offered in the same amount as your liability coverage (RCW 48.22.030). It includes property damage to your car unless you reject that part.

What the minimums mean in practice: suppose you cause a crash in Seattle traffic that injures another driver and damages a late-model SUV. The driver has $40,000 in medical bills and the SUV needs $22,000 in repairs. Your policy pays $25,000 toward the injuries and just $10,000 toward the SUV. That leaves $27,000 plus any pain-and-suffering award that the other side can pursue against you. Washington's $10,000 property damage minimum is one of the lowest in the country (state minimum vs full coverage: which do you need?, liability limits decoder).

Fault system and what it means after a crash

Washington is an at-fault state. The at-fault driver's liability insurance pays for the other side's injuries and damage, and there is no tort threshold. If you kept PIP, it pays your own medical bills and lost wages quickly regardless of fault, and your insurer may later seek reimbursement from the at-fault driver's insurer (subrogation).

Washington follows pure comparative fault (RCW 4.22.005). Any fault on your part reduces your damages proportionately but never bars recovery, so a driver who is 80% at fault can still collect 20% of their losses. See comparative vs contributory negligence.

Optional coverage worth considering here

• Underinsured motorist coverage. The Insurance Research Council estimated 19.1% of Washington drivers were uninsured in 2023, one of the higher rates in the country. Many more carry only 25/50/10 (uninsured and underinsured motorist coverage explained, what to do after an accident with an uninsured driver).
• PIP. Rejecting it saves little, and it pays quickly without waiting for a fault decision (Personal injury protection (PIP) explained).
• Higher property damage liability. $10,000 rarely covers a modern vehicle.
• Collision and comprehensive for theft, break-ins, wet-weather crashes and winter driving over the Cascades.

What drives rates in Washington

The NAIC's average expenditure in Washington was $1,153 in 2023, below the national $1,281.60. Costs are highest in the Seattle–Tacoma–Everett corridor, where congestion, vehicle theft and claim frequency are greater. The high share of uninsured drivers raises the cost of underinsured motorist coverage. Rising repair costs for newer vehicles push up collision premiums (why car repairs cost so much more than they used to). Rural eastern Washington drivers generally pay less but face long distances, ice and wildlife.

Penalties for driving uninsured

Under RCW 46.30.020, police can ask for proof of insurance at any traffic stop or crash. You can show it on a phone, and the officer may view only the proof. Failing to show proof creates a presumption that you are uninsured and is a traffic infraction, with penalties set by court rule. The Office of the Insurance Commissioner notes that drivers without proof will be ticketed. See penalties for driving without insurance.

SR-22 and high-risk drivers

The Department of Licensing can require proof of future financial responsibility, usually an SR-22 filed by your insurer. This typically follows suspensions for offenses such as DUI, driving while suspended, an uninsured crash or an unpaid crash judgment. Ask the Department of Licensing how long your filing must stay in force. If you have trouble finding coverage, the Insurance Commissioner's guide "What if I can't find auto coverage?" explains your options (SR-22 insurance explained, high-risk car insurance: options when insurers say no).

Insurers with a strong presence in Washington

State Farm, Progressive, GEICO, Allstate and Farmers Insurance are major national writers in the state. Liberty Mutual sells through its Safeco brand, which has deep roots in Seattle. PEMCO Insurance, a Seattle-based mutual, focuses on the Northwest. USAA serves the large military community around Joint Base Lewis-McChord and Naval Base Kitsap (regional car insurers: when smaller carriers can beat the giants).

Where to get help

The Washington State Office of the Insurance Commissioner Consumer Advocacy line is 800-562-6900 (8:30 a.m. to 4:30 p.m., Monday through Friday). You can also use the "Ask an insurance expert" form at insurance.wa.gov. The office can explain PIP and UIM rules, help with claim disputes and take complaints (how to file a complaint against a car insurance company). License suspensions and SR-22 questions go to the Department of Licensing. Washington allows three years to sue for injuries or property damage (RCW 4.16.080; see statutes of limitations for car accident claims). Ask a licensed attorney about your claim.
