Required Auto Insurance & Minimum Limits in Washington

Washington generally requires financial responsibility before the vehicle is operated

RCW 46.30.020 provides the basic Washington rule. A person generally may not operate a motor vehicle subject to Washington registration unless the person is insured under a motor-vehicle liability policy with at least the statutory minimum limits or is covered through another authorized form of financial responsibility.

For most individual motorists, compliance means maintaining an automobile liability policy. Larger fleets and persons able to satisfy Washington's statutory financial requirements may use one of the alternative methods.

The ordinary Washington minimum is 25 / 50 / 10

RCW 46.30.020 incorporates the liability limits stated in RCW 46.29.090.

The claimant's legally recoverable damages are determined by the actual injuries and losses. Insurance limits determine how much a particular policy may contribute—not the maximum legal value of the claim.

A Washington driver must be able to show proof of financial responsibility

RCW 46.30.020 requires proof of financial responsibility to be provided when requested by a law-enforcement officer.

RCW 46.30.030 requires an insurer issuing or renewing a motor-vehicle liability policy to provide an insurance identification card.

Failure to display proof when requested creates a statutory presumption that the driver lacks required insurance and can result in a traffic infraction.

If the driver actually had compliant coverage at the time of the citation, Washington law provides procedures for presenting evidence to the court and obtaining dismissal of the insurance citation, subject to the statute's administrative-cost provisions.

Washington allows alternatives to an ordinary liability policy

RCW 46.30.020 expressly recognizes several forms of financial responsibility.

Chapter 46.30 contains limited statutory exceptions

Washington's mandatory-liability chapter does not govern every vehicle category in exactly the same way.

RCW 46.30.020 presently excludes from that chapter certain vehicles governed by separate statutory systems, including:

• specified vehicles governed by RCW 46.16A.170;
• common or contract carriers registered with the Washington Utilities and Transportation Commission;
• motor-driven cycles as statutorily defined;
• mopeds; and
• wheeled all-terrain vehicles.

Commercial carriers, rideshare vehicles, government fleets and other specialized uses should therefore be investigated under the statutes applicable to those activities rather than assuming the ordinary passenger-vehicle rule controls.

Permission can matter when someone other than the owner is driving

A common crash question is whether the vehicle owner's insurance covers another person who was driving the vehicle.

Washington's Financial Responsibility Act contains an important permissive-use provision for a certified owner's motor-vehicle liability policy. RCW 46.29.490 provides that such a policy insures the named insured and another person using the covered vehicle with the named insured's express or implied permission.

In an actual crash investigation, obtain the complete policy and determine:

• who is a named insured;
• which vehicles are listed;
• how the policy defines an insured;
• whether the driver had express or implied permission;
• whether an exclusion or endorsement is asserted;
• whether another owner's, driver's or household policy also applies; and
• which policy is primary or excess if several coverages apply.

An insurer cannot answer a coverage question merely by saying “excluded”

Washington automobile policies may contain exclusions and limitations, but the validity and scope of an exclusion depend on the policy language, applicable insurance statutes, Washington public policy and controlling appellate decisions.

Washington courts have repeatedly distinguished between permissible limitations on an insurer's assumed risk and provisions that conflict with statutory or public-policy protections.

Liability coverage protects against legally imposed responsibility

Liability insurance does not automatically pay every person injured in an accident. It responds when an insured becomes legally responsible for covered bodily injury or property damage, subject to the policy and Washington law.

Liability coverage ordinarily does not pay for damage to the insured's own automobile. That normally requires collision, comprehensive or some other first-party physical-damage coverage.

The minimum policy should never end the coverage search

A crash victim may initially learn only that the other driver has a 25/50/10 policy. That information is useful, but incomplete.

The next investigation should determine whether any of the following exists:

After a crash, verify insurance independently

An insurance card is evidence of a policy relationship, but it does not prove that every relevant coverage applies to the accident.

A proper investigation should obtain or confirm:

• the insurer's full legal name;
• policy number;
• named insured;
• policy period;
• covered vehicle;
• identity and status of the driver;
• liability limits;
• all endorsements and exclusions relied upon;
• other insurance clauses;
• umbrella or excess coverage;
• commercial or employer coverage; and
• applicable UIM and PIP policies.
