The “ownership, maintenance and use” clause is designed to protect the named insured against all claims for damages arising out of the operation of any owned or nonowned automobile. McMichael v. American Ins. Co., 351 F.2d 665, 668 (8th Cir. 1965); 12 G. Couch, Insurance § 45:67, at 155-56 (2d R. Anderson ed. 1964) (hereinafter cited Couch on Insurance). To fall within the coverage provided by this clause, title to the automobile legal or equitable is not necessary; legal possession or responsibility for its use is sufficient where there are no questions regarding the formalities of title transfer. Couch on Insurance § 45:62, at 151.

The following rules are applicable in the interpretation of insurance policies. An insurance policy is a written contract between the insured and the insurer. Sears, Roebuck & Co. v. Hartford Accident & Indem. Co., 50 Wn.2d 443, 449, 313 P.2d 347 (1957); accord, Vandivort Constr. Co. v. Seattle Tennis Club, 11 Wn. App. 303, 310, 522 P.2d 198 (1974). Insurance contracts are to be interpreted to give effect to the intent of the parties, Thomas v. Grange Ins. Ass’n, 5 Wn. App. 820, 822, 490 P.2d 1316 (1971), and cannot be read in a vacuum. Ames v. Baker, 68 Wn.2d 713, 415 P.2d 74 (1966). In construing an exclusionary clause in an insurance policy the purpose of the insurer in inserting the particular clause must be considered. State Farm Mut. Auto. Ins. Co. v. Phillips, 2 Wn. App. 169, 177, 457 P.2d 189, 46 A.L.R.3d 1013 (1970). An exclusionary clause is to be construed in favor of the insured and most strongly against the company that has written the policy. Dickson *839 United States Fidelity & Guar. Co., 77 Wn.2d 785, 789, 466 P.2d 515 (1970) . But this rule should not be permitted to be used to make a plain agreement ambiguous for the purpose of construing it in favor of the insured. West American Ins. Co. v. State Farm Mut. Auto. Ins. Co., 80 Wn.2d 38, 44, 491 P.2d 641 (1971). Any ambiguities in an exclusionary clause must be construed most favorably to the insured. Dairyland Ins. Co. v. Ward, 83 Wn.2d 353, 358, 517 P.2d 966 (1974). Language in insurance policies is to be interpreted in a manner in which it would be understood by the average man, and not in a technical sense. Glen Falls Ins. Co. v. Vietzke, 82 Wn.2d 122, 125, 508 P.2d 608 (1973); Scales v. Skagit County Medical Bureau, 6 Wn. App. 68, 70, 491 P.2d 1338 (1971) . And that interpretation most favorable to the insured must be applied if the policy is fairly susceptible to two different interpretations, even though a different or technical meaning may have been intended by the insured. Glen Falls Ins. Co. v. Vietzke, supra at 126; see Rowland v. State Farm Mut. Auto. Ins. Co., 9 Wn. App. 460, 464, 512 P.2d 1129 (1973).
