New Washington State Car Insurance Laws: What Changed in 2026 (and What Didn't)

Washington's minimum car insurance limits did not change in 2026. They're still 25/50/10 under RCW 46.29.090: $25,000 for injury or death of one person, $50,000 for two or more people, and $10,000 for property damage, per accident. That's been the law since September 1, 1980, and as of October 2026 no increase has been enacted.

I say that first because a lot of what you'll read online gets it wrong. I went through the Legislature's final summary of the 2026 session and found no bill that changed required auto coverage, limits or rating. The insurance-regulation bills on that list include life insurance lapse notices (SHB 2428) and travel insurance (SSB 6248), not auto.

So what did change? Mostly the claims side. Your policy now has to include an appraisal clause, the insurance commissioner overhauled the claims-handling rules, renewal notices are about to get a new disclosure, and several driving-record laws that feed into what you pay have kicked in or are coming. Here's the list in date order, and what each one means for you as a driver.

Source: RCW 46.29.090; Laws of 1980, ch. 117; WAC 284-30-391; WAC 284-30-380; RCW 44.04.010.

Every change, by effective date

This is the full list of auto-related changes I could trace to a statute or adopted rule. Bills that passed but haven't taken effect yet are included with their start dates.

Source: RCW 48.18.620; SSB 5127 session law; WAC 284-20-310; RCW 46.20.2892; RCW 46.20.1191; HB 2604; ESHB 1187; E2SSB 6066; WAC 308-56A-460; WSR 26-17-089; WSR 26-15-007; RCW 46.20.760; RCW 46.61.090.

The minimums: still 25/50/10

The limits went from 15/30/5 to 25/50/10 on September 1, 1980, under Laws of 1980, chapter 117. The statute's history on the Legislature's site ends there, and the Department of Licensing's mandatory insurance page lists the same three numbers today. If you saw "25/50/20" somewhere, it isn't Washington law.

Low limits that haven't moved in more than four decades are the real story. A $10,000 property damage limit doesn't stretch far when you hit a newer car. Whatever goes past your limit can come back to you personally. That's why I'd treat the legal minimum as a floor, not a recommendation. My post on Washington car insurance requirements walks through what each piece of coverage does.

What to do: pull up your declarations page and find the three liability numbers. If they read 25/50/10, ask your agent at renewal what the next step up would cost.

January 1, 2026: an appraisal clause in every policy with physical damage coverage

Engrossed Senate Bill 5721 (Chapter 394, Laws of 2025) passed the House 96-1 and the Senate 46-2 on final passage. It's now RCW 48.18.620. Every auto policy that includes first-party physical damage coverage (collision, comprehensive) issued or renewed on or after January 1, 2026 must give you a right to appraisal when you and your insurer disagree about the actual cash value or the amount of loss on your car.

Note the scope: this is about your own car under your own policy. It doesn't apply to a claim against the other driver's insurer.

Here's how it works under the statute:

1. Either side makes a written demand for appraisal.
2. Within 10 days, each side picks a "competent and disinterested" appraiser. Competent means real expertise in valuing the loss; disinterested means no direct financial stake in the outcome.
3. The appraisers have 30 calendar days from selection to finish. If they need more time, they have to give a reasonable basis before day 25.
4. If they can't agree, they pick an umpire. If they haven't picked one within 15 days, either appraiser can ask the insurance commissioner to identify a registered umpire.
5. Agreement by any two of the three is binding.

Each side pays its own appraiser and half the umpire.

The OIC's umpire rule, WAC 284-20-310, took effect January 31, 2026. A registered umpire needs at least five years as an auto-claims appraiser or collision repair specialist, at least five prior turns as an umpire on an appraisal panel, an auto-repair degree or professional certification, and an appraisal certification, and must attest to being competent and disinterested before presiding.

What to do: appraisal costs money (your appraiser plus half the umpire), so it makes most sense when the gap between the offer and your number is large enough to cover that. Before you demand it on a totaled car, read the valuation report line by line. Under the new claims rules, the insurer must tell its appraiser about the total-loss calculation rules in WAC 284-30-391 and can't apply an award built on a valuation that ignores them. More on that in my Washington total loss post.

January 15, 2026: collector cars must be insured

Before this year, cars registered with collector vehicle or horseless carriage plates were carved out of Washington's mandatory liability insurance law. Substitute Senate Bill 5127 deleted that exemption from RCW 46.30.020 effective January 15, 2026.

From that date, anyone applying for collector plates has to show a current liability or collector vehicle policy with at least the 25/50/10 limits, plus proof of a second vehicle used for daily driving (DOL may make exceptions). Drivers on collector plates have to keep that coverage, and the requirement applies when the car is on a public highway.

What to do: if you own a classic on collector plates and let the insurance lapse because you didn't have to carry it, that's over. Get a policy in place before you drive it on a public road.

April and May 2026: driving-record changes

These aren't insurance laws, but your driving record is one of the things insurers look at, so they matter.

Ending a suspension early (April 1, 2026). Under SHB 1244, now in RCW 46.20.2892, a driver facing a 60-day suspension for three or more moving violations in a year, or four or more in two years, can end it early by finishing DOL's safe driving course. One year of probation follows. You can do this only once every five years, and it isn't available for probation violations. I haven't seen any source showing how insurers treat this, so don't assume it changes your premium.

Work zone course for new drivers under 25 (May 1, 2026). Anyone under 25 applying for a first license must pass a free, DOL-approved online course on work zone and first responder safety, under RCW 46.20.1191(3). DOL can waive it if the course isn't available. This runs until January 1, 2031.

June 11, 2026: three laws from the 2026 session

Totaled car paperwork without a notary. House Bill 2604 added a line to RCW 46.12.600: the documents you sign to transfer a totaled car to your insurer don't need a notarized signature, can be signed electronically, and can include a limited power of attorney that DOL must accept. The 15-day deadlines didn't change. You still report a destroyed vehicle to DOL within 15 days, and the insurer reports a total loss within 15 days after settlement. Separately, DOL's market value threshold under WAC 308-56A-460 is now $12,220 (effective August 20, 2026). It decides whether a totaled car six or more years old gets a salvage title, not whether it's totaled.

A 120-day wait before ambulance bills go to collections. Under ESHB 1187, an ambulance service can't sell or assign a bill for transport after a motor vehicle accident to a collection agency until at least 120 days after the first billing statement goes to the patient and other responsible party. Pedestrians and cyclists hit by a vehicle count. The way I read it, that gives PIP, medical payments or the other driver's liability coverage time to pay first. If the commissioner sees a pattern of unresolved violations, it can refer it to the Department of Health, which may fine.

What to do with that: when the ambulance bill arrives, send it to your insurer with your claim number right away. The 120 days is breathing room, not a reason to wait. If you carry personal injury protection, my post on PIP in Washington explains how that coverage works.

Crash prevention zones. E2SSB 6066 lets local governments set up crash prevention zones on part of U.S. 395 (mileposts 23 to 32, Pasco to Mesa) and two stretches of Highway 12, with automated speed cameras allowed. In a zone, the base penalty for using a phone or other personal electronic device while driving is doubled and can't be waived, reduced or suspended (RCW 46.61.672(5)). From January 1, 2029, cities, counties and WSDOT can create zones on high-crash roads statewide (RCW 46.61.090).

October 18, 2026: new claims-handling rules

This is the biggest change of the year for anyone who files a claim. The OIC's rule package R 2025-05 (WSR 26-17-089) amended 15 sections of the state's minimum claims-handling standards. In its October 19 announcement, the OIC said the rules "hadn't changed since they were adopted in 1978." It held a workshop in 2023 after a historic jump in auto claims complaints, and more than 80% of complaints leading up to that workshop cited claim handling.

These are the deadlines and rights that now apply to auto claims:

Source: WAC 284-30-360; WAC 284-30-380; WAC 284-30-390; WAC 284-30-391; WSR 26-17-089 (WAC 284-30-370); OIC Matter R 2025-05.

Two details deserve a second look. The rental rule doesn't create rental coverage; once you've agreed on the amount, it only stops an insurer from cutting off coverage you already bought the moment the check goes out. And the 150-mile limit is a cap, not a target: the rule says "a reasonable distance," so comparables from 140 miles away in a different market are still worth questioning.

What to do: put requests in writing and date them. Ask for the pricing-data details if the estimate's labor rate looks low. If you did a photo estimate and the number is off, ask for an in-person inspection; the five-business-day clock starts with your request. If deadlines slip, you can file a complaint with the OIC (my post on filing a complaint with the insurance commissioner shows how).

November 1, 2026 onward: explaining premium increases

Since June 1, 2024, you've been able to ask in writing why your auto or home premium went up at renewal, and the insurer has had to give a reasonable explanation. The OIC's amended rule R 2024-07 (WSR 26-15-007, effective August 2, 2026) adds steps and pushes the biggest one back to 2029 so the agency can collect data on the first phase.

Source: WSR 26-15-007; OIC Matter R 2024-07.

What to do: you don't have to wait for any of this. If your renewal went up, email the insurer and ask why; an email counts as a written request. Then compare the answer with what's in my post on Washington car insurance rates. Once March 2027 arrives, ask specifically for the top factors.

2027 and later: young drivers and speed limiters

Driver training (from January 1, 2027). ESHB 1878 phases in required driver training for first-time license applicants under RCW 46.20.1191: age 18 from January 1, 2027, under 20 from 2028, under 21 from 2029 and under 22 from 2030. DOL can pause the phase-in if there aren't enough courses or instructors. Also from January 1, 2027, a new license holder aged 18 to under 22 with two moving violations must take a safe driving course within 180 days of DOL's notice or lose the license until it's done; a similar rule covers ages 22 to under 25 until 2031.

If you have a teen or young adult about to license and you plan to add them to your policy, build the course into the timeline.

Speed limiters (from January 1, 2029). The BEAM act (ESHB 1596) requires intelligent speed assistance devices, which keep a car at the speed limit, in some cases: the first 120 days of probation after a moving-violation suspension that included excessive speeding, some restricted licenses, and by court order (at least six months when a court finds excessive speeding during a criminal traffic offense). The driver pays the installation or lease plus a $21 monthly fee, with waivers for people who can't afford it (RCW 46.20.760). The Legislature's finding: in 2023 more than 30% of fatal crashes on Washington roads involved speeding.

What did not change

Source: RCW 46.29.090; RCW 46.30.020; IRLJ 6.2; House OPR Summary of Legislation 2026; OIC R 2022-08; RCW 48.19.460.

The uninsured driving rule in RCW 46.30.020 was touched in 2025 only to drop the collector-plate exemption. The penalty itself didn't move. The court rule sets a $250 base penalty for failing to provide proof of insurance, before the add-on assessments, and DOL says you "could receive a fine of $550 or more." If you were insured but couldn't show it, the citation is dismissed when you prove coverage, with up to a $25 administrative cost. Details in my post on driving without insurance in Washington.

What to watch in the 2027 session

The Legislature convenes on the second Monday of January, which in 2027 is January 11 (RCW 44.04.010). The insurance commissioner has posted the bills the office will ask for, describing them as ways to "protect consumers from fraud and lower the cost of auto and homeowners insurance." Among them:

• authority for the OIC to order restitution to consumers harmed when an insurer breaks state insurance law, and to fine per violation;
• a ban on post-loss assignment of benefits;
• updated fraud laws, making each criminal act a class B felony with a 10-year charging window.

These are requests, not law. Bills change or die in session all the time, so I wouldn't plan around any of them. I'll update this post after the session ends. You can read the full list on the OIC 2027 legislative priorities page.

FAQ

Did Washington change its minimum car insurance requirements in 2026?

No. The minimums under RCW 46.29.090 are still 25/50/10: $25,000 per person, $50,000 per accident for injury or death, and $10,000 for property damage. They have been the same since September 1, 1980.

What is the new auto appraisal law in Washington?

Under RCW 48.18.620 (ESB 5721), auto policies with physical damage coverage issued or renewed on or after January 1, 2026 must give you a right to appraisal when you and your insurer disagree about your car's actual cash value or the amount of loss. Each side pays its own appraiser and half the umpire.

How long does an insurer have to accept or deny a car insurance claim in Washington?

Under WAC 284-30-380 as amended effective October 18, 2026, the insurer must tell a first-party claimant whether the claim is accepted or denied within 30 calendar days after receiving notice of the claim. If it needs more time, it must say so in writing within that period, give reasons, and update you every 30 days.

Do collector cars need insurance in Washington?

Yes, starting January 15, 2026. SSB 5127 removed the exemption for collector vehicle and horseless carriage plates from the mandatory insurance law, and collector plate applicants must show liability or collector vehicle insurance.

Your own policy wording and Washington law control how your coverage and claims work. Confirm your situation with a licensed agent, the Washington Office of the Insurance Commissioner, or, for legal questions, an attorney.
