At three o'clock in the morning, an automobile belonging to the appellant was driven at a great rate of speed through a curve and down a gulch where it overturned and thereafter ceased to exist as a going concern. The appellant then sought *Page 308 to recoup its loss from the respondent on its policy of insurance against "accidental collision." The jury gave a verdict for the appellant, but the court nevertheless gave judgment for the respondent, and this appeal resulted.
The court was right and the jury was wrong. For Ploe v.International Indemnity Co., 128 Wash. 480, 223 P. 327, decided that a loss occasioned by an automobile contacting with the earth was not covered by a provision in the insurance policy referring to "collision." A vigorous argument is made against the soundness of that decision by the appellant, fortifying it by the citation of authorities from numerous respectable jurisdictions. But in spite of the argument and authorities we are of the same opinion still. This adherence to that decision disposes of the major of appellant's contentions.
But one other assignment needs our attention, and that is, that parol evidence should have been admitted to explain what the parties to the contract intended by the use of the word "collision." It appears that the agent of the respondent who wrote the policy is also an officer of the appellant to whom the policy was issued, and the evidence offered was to the effect that this person, when he wrote the policy, intended that the word "collision" should cover a situation such as is presented by the facts of this case. To allow such evidence would be to violate the rule against the admission of parol testimony to vary the terms of a written contract, and the effect of this rule cannot be avoided by the contention that another rule applies, which is that parol testimony can be admitted to explain ambiguities, for, as we view it, there is no ambiguity associated with the word "collision." This court has held in the Ploe case that "collision" does *Page 309 not include an upset and overturn. If that is true, there is no ambiguity here and the evidence could not be admissible.
For these reasons the judgment is affirmed.
