Who Is an Insured Under Washington Auto Insurance?

“Insured” does not mean the same thing for every automobile coverage. Liability, underinsured motorist coverage and Personal Injury Protection can protect different people under different circumstances. Washington coverage analysis therefore begins by identifying the person, the vehicle, the coverage involved and the exact policy definition that applies.

There is no single universal definition of “insured”

Automobile insurance contains several separate coverages. A person can qualify as an insured for one coverage while failing to qualify for another.

Liability

Who is protected from claims?

Liability coverage generally focuses on persons or organizations insured against legal responsibility arising from use of a covered vehicle.

UIM

Who receives first-party protection?

UIM can protect named insureds and household family members more broadly than people who qualify only because they occupy a covered vehicle.

PIP

Washington supplies a statutory definition

Chapter 48.22 RCW expressly defines categories of persons who can qualify as insureds for Washington PIP purposes.

Coverage-analysis rule: never ask only, “Is this person insured?” Ask, “Is this person an insured for this particular coverage under this policy and these facts?”

The named insured usually occupies the strongest coverage position

The declarations page identifies the named insured. That designation can affect liability coverage, UIM, PIP, policy rights, cancellation notices, rejection rights and other contractual protections.

RCW 48.22.005 provides a statutory definition for chapter 48.22: “named insured” means the individual named in the declarations and includes that person's spouse when the spouse resides in the same household.

The declarations page is therefore a critical document. It identifies the person around whom many policy definitions are built, but the complete policy still must be read because different coverages may expand insured status beyond the named insured.

Liability insured status commonly follows ownership, permission and policy definitions

A standard automobile liability policy generally protects the named insured and may extend coverage to additional people using a covered vehicle with permission.

Washington's Financial Responsibility Act expressly illustrates this structure for certified owner's policies. RCW 46.29.490 requires such policies to insure:

  • the person named in the policy; and
  • another person using the covered vehicle with the named insured's express or implied permission.
RCW 46.29.490 is not a universal definition for every private policy. It directly governs policies certified as future proof of financial responsibility under chapter 46.29 RCW. Ordinary private policies still require examination of their own liability-insured definitions and Washington law applicable to them.

Modern policies may also extend liability insured status to:

  • resident family members;
  • permissive users;
  • organizations legally responsible for a covered insured's conduct;
  • employees using qualifying covered autos;
  • users of temporary substitute vehicles; and
  • persons using qualifying nonowned vehicles.

The specific policy controls subject to Washington statutory and public-policy limitations.

Permission can determine whether another driver becomes an insured

Washington cases have long analyzed express and implied permission under automobile liability omnibus clauses.

Express permission

Direct authorization

The owner or named insured expressly allows the person to use the vehicle.

Implied permission

Permission inferred from conduct

Permission may sometimes be established by conduct, practice, relationship and the surrounding circumstances rather than explicit words.

Hamm v. Camerota
48 Wn.2d 34, 290 P.2d 713 (1955)

Washington held that coverage under an omnibus clause required the driver's use to be within express or implied permission attributable to the named insured.

Holthe v. Iskowitz
31 Wn.2d 533, 197 P.2d 999 (1948)

The Washington Supreme Court rejected the proposition that permission to one user automatically permits that person to delegate use to another driver. The policy and facts surrounding the secondary user's permission matter.

Permission to use a vehicle does not automatically include unlimited authority to lend it to anyone else. Secondary-permittee cases require close attention to the named insured's actual authorization and the policy language.

Washington UIM distinguishes between broad insured status and vehicle-based insured status

RCW 48.22.030 requires UIM protection for “persons insured” under the automobile policy, subject to statutory exceptions and permitted written rejection.

Washington Supreme Court decisions commonly distinguish two important categories of UIM insureds.

Class 1

Named insureds and qualifying family members

These insureds typically receive personal UIM protection that is not limited merely to occupying the vehicle listed on the policy.

Class 2

Other occupants of the covered vehicle

These persons may qualify for UIM because they occupy a covered vehicle but generally do not receive the same portable status as a named insured.

Blackburn v. Safeco Insurance Co.
115 Wn.2d 82, 794 P.2d 1259 (1990)

Explains the important distinction between named-insured/family-member UIM coverage and coverage extended to other persons because they are occupying a covered vehicle.

Tissell v. Liberty Mutual Insurance Co.
115 Wn.2d 107, 795 P.2d 126 (1990)

Reinforces that named insureds and family members occupy a materially different UIM coverage position from persons covered only as vehicle occupants.

Kowal v. Grange Insurance Association
110 Wn.2d 239, 751 P.2d 306 (1988)

A specifically named insured could receive UIM protection even though she was not occupying the insured vehicle at the time of injury.

Practical consequence: a person injured while walking, bicycling, riding in another vehicle or using a nonowned automobile may still have a UIM claim if that person qualifies as a named insured or covered family member under another policy.

Washington generally ties the UIM insured class to the policy's liability insured class

Washington decisions recognize that RCW 48.22.030 protects persons insured under the automobile liability policy. The insurer may define the class of insureds, but it ordinarily cannot define a narrower UIM class than the insured class contemplated by the liability coverage and governing statute merely to defeat the statutory protection.

Federated American Insurance Co. v. Raynes
88 Wn.2d 439, 563 P.2d 815 (1977)

Washington Supreme Court authority recognizing that the statutory UIM/UM protection must be made available to a class of insureds at least as broad as the class insured under the primary liability coverage.

This does not make everyone connected to the vehicle a UIM insured. The starting question remains whether the person comes within the liability or UIM insured definition in the first place.

Washington expressly defines who is insured for PIP

RCW 48.22.005 applies definitions throughout chapter 48.22 unless the context requires otherwise.

For PIP purposes, the statutory insured class includes two principal groups.

Household class

Named insured and qualifying household members

The named insured and household residents related by blood, marriage or adoption, along with a ward, foster child or stepchild of the named insured.

Vehicle-related class

Occupants, users and pedestrians

A person injured while occupying or using the insured automobile with permission, or a pedestrian accidentally struck by the insured automobile.

RCW 48.22.005 defines “occupying” broadly to include being in, upon, entering into, or alighting from the vehicle.

The statute also defines “named insured” to include the individual named in the declarations and that person's spouse when the spouse resides in the same household.

PIP can therefore protect more than the vehicle owner. Depending on the facts, a resident family member, permissive occupant, permissive user or pedestrian struck by the insured automobile may qualify.

Household status can materially change coverage

Automobile policies frequently extend important coverages to a named insured's spouse and qualifying resident relatives. Whether a person is a resident of the household can therefore determine access to UIM, PIP and other coverage.

Relevant facts can include:

  • where the person regularly sleeps;
  • where personal belongings are kept;
  • mailing and driver's-license addresses;
  • financial dependence;
  • family relationships;
  • temporary absence for college, military service or work;
  • the person's intent concerning residence; and
  • the wording of the particular policy definition.
Do not resolve household status from one address alone. Residency can be a fact-specific coverage question and should be investigated from the complete circumstances.

A vehicle occupant may be insured under one policy and not another

A passenger injured in a Washington crash might potentially qualify under:

  • UIM coverage on the occupied vehicle;
  • PIP coverage on the occupied vehicle;
  • the passenger's own automobile policy;
  • a resident household member's policy;
  • commercial or rideshare insurance applicable to the vehicle; or
  • some combination of these sources.
Occupancy is a coverage trigger, not necessarily the only trigger. Always investigate whether the injured passenger has personal insured status under another policy independent of the vehicle being occupied.

Business auto policies require special attention to who the named insured is

A commercial automobile policy may name a corporation, limited liability company, partnership, governmental entity or other organization rather than an individual.

That can materially change insured-status analysis.

Smith v. Continental Casualty Co.
128 Wn.2d 73, 904 P.2d 749 (1995)

The Washington Supreme Court examined UIM insured status under a commercial policy in which the named insured was a business rather than the injured individual. The employee did not receive the same status as an individually named insured merely because of his relationship to the business.

Commercial policies may define insured status according to:

  • ownership of the covered auto;
  • employee status;
  • permission;
  • scope of employment;
  • listed auto symbols;
  • hired and nonowned auto endorsements;
  • executive officer status; and
  • special UIM endorsements.
“Employee” does not automatically mean “insured for every coverage.” Liability insured status and UIM insured status must each be established from the commercial policy and Washington law.

Exclusions can affect insured status but are not automatically controlling

Insurers may rely on exclusions concerning vehicle ownership, regular use, household status, excluded drivers, commercial use or other risks.

Washington courts generally enforce valid policy limitations unless they conflict with a statute, recognized public policy or controlling insurance law.

Mutual of Enumclaw Insurance Co. v. Wiscomb
97 Wn.2d 203, 643 P.2d 441 (1982)

The Washington Supreme Court invalidated a household liability exclusion that eliminated protection for a class of innocent victims, emphasizing Washington's public policy favoring compensation of automobile-accident victims.

Coverage analysis sequence: identify the insured definition → determine whether the person initially qualifies → identify any exclusion → determine whether Washington law permits that exclusion to operate as asserted.

Citizen workflow for determining Washington insured status

Identify the coverage being analyzed. Liability, UIM and PIP can use different insured definitions.
Obtain the declarations page. Identify every named insured and listed vehicle.
Obtain the complete policy and endorsements. Find the actual definition of “insured,” “you,” “family member,” “occupying,” “covered auto” and related terms.
Determine the person's relationship to the named insured. Examine spouse, household, family, employee and organizational status.
Determine the person's relationship to the vehicle. Identify ownership, permission, occupancy, use and regular-use status.
Investigate express or implied permission. For another driver, determine who authorized use and the scope of that permission.
For UIM, determine whether the person is a personal insured or only a vehicle occupant. That distinction can determine whether coverage follows the person away from the insured automobile.
For PIP, apply RCW 48.22.005 directly. Check named-insured, household, permissive occupancy/use and pedestrian categories.
For commercial policies, identify the legal named insured. Do not assume employees automatically receive all coverages purchased by the business.
Identify every exclusion relied on by the carrier. Obtain the actual endorsement or policy language.
Compare exclusions with Washington statutes and case law. An exclusion is not necessarily valid merely because it appears in the contract.
Repeat the analysis for every potentially applicable policy. A person can have different insured status under several policies arising from the same crash.

Bottom line

Washington automobile insurance does not have one universal class of insureds. Liability coverage may depend on ownership and permission. UIM gives named insureds and qualifying family members broader personal protection than people insured only because they occupy a covered vehicle. PIP has its own statutory insured categories, including household members, permissive users and occupants, and pedestrians struck by the insured automobile. Identify the coverage, read the complete policy, determine the person's relationship to the named insured and vehicle, and repeat that analysis for every potentially applicable policy.
