Washington State Car Insurance Laws and Requirements

Washington state car insurance laws require every driver to carry liability coverage of at least $25,000 per person for bodily injury, $50,000 per accident, and $10,000 for property damage.¹ Insurers must also offer uninsured motorist and personal injury protection coverage, which you can decline only in writing. Drive without coverage and you face a fine of roughly $550 for a first offense, plus personal liability for any crash you cause.

The 25/50/10 Minimum Liability Coverage

The state minimums pay the other driver, not you. That $25,000 per person and $50,000 per accident cover the other side’s medical bills and lost wages when you’re at fault; the $10,000 covers their vehicle and other property.¹ Nothing in a minimum policy repairs your car or treats your injuries.

Washington is a fault-based state, so the driver who caused the crash bears the financial responsibility.² If your policy limits don’t cover the damage you caused, the other driver can sue you personally for the rest. A single emergency room visit can eat through $25,000, and a multi-vehicle crash can pass $50,000 in combined injuries quickly. Drivers with home equity or savings have the most exposure from carrying only the state minimum.

A certificate of deposit or surety bond of at least $60,000 can substitute for a policy, but few drivers have that kind of capital sitting idle.³ For nearly everyone, a standard auto policy is the only realistic way to meet the requirement.

Uninsured and Underinsured Motorist Coverage

Every new auto policy in Washington must include uninsured motorist (UM) and underinsured motorist (UIM) coverage matching your liability limits. You or your spouse can reject it in writing, and that rejection carries through renewals until you ask for it back in writing.⁴

UM pays your medical bills and lost wages when the at-fault driver has no insurance. UIM covers the gap when the other driver has a policy that isn’t large enough to pay your losses. Both extend to hit-and-run crashes and to collisions caused by a “phantom vehicle” that never made contact with your car.⁴

Roughly 19 percent of Washington drivers carry no insurance, which puts the state among the ten worst nationally.⁵ About one in five drivers around you may have nothing to pay a claim with. That’s the coverage most people wish they’d kept after a bad crash with an uninsured driver.

Personal Injury Protection

Insurers must offer personal injury protection (PIP) as an add-on. You can decline it in writing, and the rejection applies to renewals until you request it back.⁶ PIP pays regardless of fault and covers the policyholder, passengers, and pedestrians the vehicle strikes.

Standard minimum PIP benefits:

Medical expenses: $10,000
Funeral costs: $2,000
Lost income: $200 per week, up to $10,000 total
Essential services (household help you can’t do because of your injuries): $5,000

Most insurers sell higher limits. PIP’s main advantage is speed: it pays without waiting for a fault determination or a lawsuit, which can take months. If your health plan has a high deductible, PIP can fill the gap while your other coverage catches up.

Proof of Insurance

You must carry proof of liability insurance and show it to law enforcement when asked. A paper card works, and so does an image on your phone; if you hand over the phone, you accept the risk of any damage while the officer holds it.⁷

If you’re cited but you actually had coverage at the time, appear in court or mail in proof and the citation will be dismissed. The court may charge a $25 administrative fee to do that.⁸

One boundary worth knowing: as of January 15, 2026, mopeds, motor-driven cycles, and wheeled all-terrain vehicles are no longer subject to the mandatory insurance requirement.⁹ Standard registered vehicles still are.

How Fault Affects What You Can Recover

Washington uses pure comparative fault. If you share blame for a crash, your recovery is reduced by your percentage of fault, but you can still collect something even if you were mostly responsible.¹⁰ A jury that finds you 30 percent at fault on $100,000 in damages awards you $70,000. Many states cut off recovery entirely once your share crosses 50 percent; Washington does not.

Because there is no cutoff, adjusters have every reason to push your share of fault up. Scene photos, witness contact information, and a police report make that harder to do.

Penalties for Driving Without Insurance

Driving uninsured is a traffic infraction. The fine amount is set by the state supreme court’s penalty schedule, and most sources put it around $550 for a first offense.⁸ Any lapse also raises your rates once you’re reinsured, since insurers treat even a one-day gap as a risk marker.

The bigger risk is causing a crash while uninsured. You’re personally liable for every dollar of the other driver’s medical bills, lost income, and property damage. If you don’t pay the resulting judgment within 30 days, the other side’s attorney can report it to the Department of Licensing, which suspends your license until the judgment is satisfied in full and you file proof of financial responsibility.¹¹

An unpaid premium sent to collections can also show up on your credit report. And because most auto insurers price policies using credit-based insurance scores, a coverage gap can raise your premium for years after you fix it.

When You Need an SR-22

An SR-22 is a certificate your insurer files with the Department of Licensing confirming you carry at least the required coverage. You’ll need one after certain serious situations, including causing a crash while uninsured, failing to pay a crash-related judgment, or being convicted of specific driving offenses.³

You must keep the SR-22 on file for three years from the date you become eligible to reinstate your license.³ Any lapse triggers an automatic notification to the DOL and can suspend your license again. The filing fee itself runs about $25 to $50, but SR-22 drivers are rated high-risk, so the premium increase over three years is where the real money goes.

Two alternatives exist for drivers who can’t find an insurer to write an SR-22 policy: a $60,000 certificate of deposit with the DOL, or a $60,000 surety bond from a bonding company authorized in Washington.³ They tie up serious capital, so they’re rarely the answer.

Reporting and Handling a Crash

Washington law requires a written accident report to law enforcement within four days if anyone is injured or killed, or if property damage to any one person’s property looks to be $500 or more.¹² Inside city limits, file with local police; outside, with the county sheriff or state patrol. Missing this step can complicate an insurance claim later.

At the scene, get from every other driver:

Full legal name, address, and phone number
Driver’s license number and issuing state
Insurance company, policy number, and agent contact
License plate, make, model, year, and color

Photograph the insurance card, the damage, skid marks, traffic signs, and road conditions before anything moves. Notify your own insurer promptly even if you weren’t at fault, because most policies require prompt reporting and can push back on a later claim if you delayed.

Ride-Share, Delivery, and Rental Situations

A standard personal auto policy excludes commercial use, so driving for a ride-share or delivery app can void your coverage while the app is active. The gap is widest when the app is on and you’re waiting for a request; the platform’s commercial policy may not fully cover that phase, and your personal policy generally won’t. Most major insurers now sell a ride-share endorsement that closes the gap. If you drive for any gig platform, ask about it before your first shift.

Your personal policy generally extends to rental cars. Liability follows you, and if you carry collision and comprehensive, those apply to damage to the rental vehicle, subject to your usual deductibles. The gap shows up when you carry only liability: damage to the rental itself isn’t covered, and you’d owe the full repair or replacement cost. Check your declarations page and any coverage your credit card offers before you decline the rental company’s collision damage waiver.
