Because an insurance policy is a contract of adhesion, any genuine ambiguity in the policy language is generally interpreted:

Why A is correct

A contract of adhesion is one that is drafted entirely by one party, the insurer, and presented to the other party on a take-it-or-leave-it basis, with no realistic opportunity to negotiate the terms. Because the insurer controls the language of the policy, courts have long held that any genuine ambiguity in the policy must be interpreted against the party that drafted it, which is the insurer. This doctrine protects consumers who lack bargaining power and encourages insurers to write clear, unambiguous policy language in the first place. The rule applies only to ambiguities that are genuinely open to more than one reasonable reading; if the language is clear and unambiguous, it is enforced as written.

Why the other options are wrong

• B) Interpreting ambiguities against the insured would reward the insurer for drafting unclear language and would defeat the entire purpose of the adhesion doctrine. Since the insured had no hand in writing the policy and no power to change its terms, the risk of unclear drafting must fall on the drafter rather than on the consumer.
• C) The doctrine focuses on the party that drafted the policy, and the agent is the insurer's representative who sells the product rather than the author of its language. Interpreting ambiguities in favor of the agent would be meaningless because the agent is not a party to the contract between the insured and the insurer.
• D) The state insurance department regulates insurers and licenses producers, but it does not adjudicate private contract disputes between an insured and an insurer. Interpretation of policy language is a matter for the courts, which apply the ambiguity rule against the drafter, not a decision made by the regulatory agency.

Memory hook

Unclear policy words? The insurer wrote them, so the insurer loses.
