Washington Motorcycle Insurance Requirements: 25/50/10 & Universal Helmet Law

Quick Answer: Washington Minimum Motorcycle Insurance

Washington requires motorcycles ridden on public roads to carry minimum liability insurance. The mandatory insurance law (RCW 46.30.020) exempts mopeds and motor-driven cycles, but not motorcycles. The state minimums are 25/50/10:

One thing that surprises many riders: Washington's rule that makes underinsured/uninsured motorist (UIM) coverage the default on auto policies does not protect you on a motorcycle. RCW 48.22.030 carves out injuries suffered "while operating or occupying a motorcycle or motor-driven cycle", so UIM for a rider is something you have to ask for and buy.

All riders and passengers must wear a motorcycle helmet meeting the federal DOT standard, with no age exemption.

Washington Motorcycle Insurance Requirements in Detail

The duty to be insured comes from RCW 46.30.020: no one may operate a vehicle subject to registration in Washington unless insured under a liability policy with at least the limits in RCW 46.29.090, or holding an approved alternative (a $60,000 certificate of deposit or liability bond, or self-insurance for owners of 26 or more vehicles). The Office of the Insurance Commissioner describes the law as applying to both motor vehicles and motorcycles.

The requirement attaches to riding, not to owning. Washington has no electronic insurance verification system, and DOL has no current authority to check coverage at registration; enforcement happens at traffic stops and after collisions. Bills to create a verification system (SB 5326 in 2023–24, SB 5864 in 2026) have not passed.

Required Coverage Breakdown

Liability Insurance (25/50/10)

Liability pays for harm you cause to other people and their property. It does not cover your own medical bills, lost wages, or damage to your motorcycle.

• $25,000 bodily injury per person (maximum one injured person can recover)
• $50,000 bodily injury per accident (total cap across all injured parties)
• $10,000 property damage (covers the other vehicle or property you damaged)

If you run a red light and hit a car carrying two people, both are injured, and their bills come to $70,000 — your policy pays $50,000 and the injured people can pursue you personally for the remaining $20,000.

Washington's $10,000 property damage minimum is low. Most modern vehicles cost far more than $10,000 to repair or replace, so upgrading this limit is worth considering.

Underinsured/Uninsured Motorist Coverage — Not Automatic for Riders

For cars, RCW 48.22.030 requires every liability policy on a vehicle registered or principally garaged in Washington to include UIM at your liability limits unless you reject it in writing. The same subsection then excludes coverage "while operating or occupying a motorcycle or motor-driven cycle".

For a rider, that means:

• A motorcycle policy is not required to include UIM. Insurers can offer it as an option — ask for it, and check the limits on your declarations page.
• The UIM on your car policy does not follow you onto your bike.

It is worth having. The Insurance Research Council estimated that 19.1% of Washington drivers were uninsured in 2023, the 10th-highest rate in the country — roughly one driver in five.

UIM protects you when:

• An uninsured driver causes your crash
• A hit-and-run driver injures you
• The at-fault driver's limits fall short of your actual damages

Personal Injury Protection

Washington's rule that insurers must offer PIP applies to automobile policies, and "automobile" is defined as a passenger car (RCW 48.22.005). Motorcycle policies are outside it. Medical payments coverage, where your insurer offers it, fills a similar role for your own injuries.

Coverages NOT Required (But Worth Having)

If you're financing your motorcycle, your lender will require comprehensive and collision coverage regardless of state minimums. For an owned bike, weigh the bike's actual cash value against the premium.

Washington Helmet Law

Under RCW 46.37.530, no one may operate or ride on a motorcycle, motor-driven cycle or moped on a state highway, county road or city street without a motorcycle helmet. The helmet must have a hard outer shell, padding, a chin or neck strap, and the manufacturer's certification that it meets the U.S. DOT standard (49 C.F.R. 571.218). There is no age exemption — it applies to every operator and passenger. The narrow exception is for enclosed vehicles with a steering wheel and seat belts, and antique motor-driven cycles.

Helmet requirements:

• Must carry the manufacturer's DOT certification
• Must be fastened with its retention strap
• Novelty helmets without DOT certification do not satisfy the law

Eye protection: if the motorcycle has no windshield, the operator must wear glasses, goggles or a face shield of a type conforming to Washington State Patrol rules.

Children: it is illegal to carry a child under 5 on a motorcycle or motor-driven cycle.

Who Must Carry Motorcycle Insurance in Washington

Required for:

• Anyone riding a motorcycle that is subject to registration in Washington
• Riders who move to Washington and register their bikes here

Outside the mandatory-insurance law (RCW 46.30.020):

• Mopeds and motor-driven cycles (the smallest, lowest-powered two-wheelers)
• Wheeled all-terrain vehicles
• Publicly owned vehicles

Off-road-only motorcycles: the law applies to vehicles subject to road registration, so a dirt bike used only off-road is outside it. Your road policy usually will not cover off-road riding either (see FAQ).

Penalties for Riding Without Insurance

Officers can ask for proof of insurance at any traffic stop or collision. Under RCW 46.30.030 your insurance ID card may be paper or electronic — an image on your phone counts.

SR-22 Requirements in Washington

An SR-22 is a certificate your insurer files with DOL to prove you carry at least the state minimum coverage. Washington requires it for people who have been convicted of certain offenses, failed to pay judgments, or owned vehicles involved in collisions they could not cover — for example, when you deposit security to lift a suspension after an uninsured crash.

In most cases you must keep it for 3 years from the date you are eligible to reinstate your license. If the insurance behind it is cancelled, the insurer notifies DOL and your license is suspended.

Not all insurers file SR-22s. Expect higher premiums and fewer carrier options if you need one.

Washington-Specific Riding Conditions

Western Washington: frequent rain means wet roads, reduced visibility and slick surfaces for much of the year. Wet-weather tires and gear matter here.

Mountain passes: US 2 over Stevens Pass and SR 20 (the North Cascades Highway) are scenic but demanding. SR 20 closes for the winter, and debris and rockfall are seasonal hazards.

Eastern Washington: hot, dry summers with limited shade on long rural highways.

Ferry routes: Washington State Ferries connects islands and peninsulas. Check the ferry system's current rules for loading motorcycles.

How to Get Motorcycle Insurance in Washington

When applying for coverage, prepare:

• Washington driver's license with motorcycle endorsement
• Motorcycle VIN, year, make, and model
• Garaging ZIP code (affects premium)
• Estimated annual mileage
• Riding history — prior violations, accidents, previous insurance

Premium factors:

• Garaging location — urban western Washington ZIP codes generally cost more than rural eastern ones
• Security features (alarm, GPS tracker) may earn discounts
• A rider-safety course often earns a discount — ask your carrier
• Multi-vehicle discounts if you also insure a car with the same carrier

Ask specifically about UIM. Because Washington's default-UIM rule does not reach motorcycles, it may not be on your quote unless you request it.

FAQ

Do I have to insure my motorcycle over the winter?

Washington's requirement applies when you ride: no one may operate a vehicle subject to registration without insurance. If you reduce your policy for winter storage (some insurers offer a storage or lay-up option), you cannot legally ride the bike until full liability coverage is back in force.

Can I ride in Washington with an Oregon or Idaho policy?

Visitors can ride on a valid policy from their home state. If you move to Washington and register your motorcycle here, you'll need a policy that meets Washington's 25/50/10 minimums.

What happens at a traffic stop if I don't have insurance?

It is a traffic infraction, and DOL says the fine can be $550 or more. If you cause a crash while uninsured, your license is suspended unless you resolve the damages within 60 days, and you may need an SR-22 to reinstate.

Is lane splitting legal in Washington?

No. RCW 46.61.608 prohibits operating a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles, and overtaking in the same lane as the vehicle being passed. If you crash while splitting lanes, expect that to weigh on the fault decision.

Does uninsured motorist coverage come with my motorcycle policy automatically?

No. Washington's default-UIM rule (RCW 48.22.030) excludes injuries suffered while operating or occupying a motorcycle. Ask your insurer to add UIM to your motorcycle policy — ideally at the same limits as your liability coverage.

Does Washington require eye protection for motorcycle riders?

Yes, unless the motorcycle has a windshield: the operator must wear glasses, goggles or a face shield of a type conforming to Washington State Patrol rules (RCW 46.37.530).

Is dirt bike riding on Washington trails covered by my motorcycle policy?

Generally no. A standard motorcycle policy covers on-road use. If you ride off-road — trails, motocross tracks, or designated ORV areas — you'd need an off-road or recreational vehicle policy for coverage there.

Summary

Washington motorcycle insurance requirements at a glance:

• Minimum liability: 25/50/10 (RCW 46.29.090), required to ride any motorcycle subject to registration
• UIM: not required and not automatic on a motorcycle policy — ask for it
• Helmets: mandatory for all riders and passengers, DOT-certified, no age exemption
• Eye protection: required unless the motorcycle has a windshield
• Lane splitting: illegal
• Uninsured fine: $550 or more; an uninsured crash can cost you your license for up to 3 years

Washington's 25/50/10 minimums are low relative to actual crash costs. With about one driver in five uninsured, adding UIM and raising your liability limits is worthwhile protection.
