In Calvert v. Farmers Insurance Company of Arizona, 144 Ariz. 291, 294, 697 P.2d 684, 687 (1985), the court concluded a provision in the plaintiff's policy disallowing UM coverage when the insured was injured in his own uninsured motor vehicle was an "other vehicle" exclusion that contravened the public policy of the statute. In doing so, the court noted: The only exception to the mandatory requirement of uninsured motorist protection7 under the Act is contained in former A.R.S. 20-259.01(D), which expressly excludes vehicles "used as public or livery conveyances or rented to others or which are used in the business primarily to transport property or equipment."
