with whom HARGRAVE, Vice Chief Justice, and HODGES and LAVENDER, Justices, join, dissenting.
The court holds that the risk carrier of uninsured/underinsured motorist [UM] coverage must answer in damages for the death of its insured even though the tort-feasor-motorist stands shielded from liability by the immunity conferred in the Workers’ Compensation Act.1 I cannot join in today’s pronouncement.
The purpose of the statutory mandate for UM coverage, 36 O.S. 1981 § 3636, is to afford first-party protection for bodily injury or death occasioned to an insured who is "... legally entitled to recover damages from owners or operators of uninsured motor vehicles_” [Emphasis added.] The insurer’s liability clearly is gauged by that of another — the uninsured/underin-sured tortfeasor. Although the carrier’s ex contractu obligation may be enforced under a longer statute of limitations than that which governs the ex delicto claim against an uninsured tortfeasor,2 the insured must nonetheless show, as a condition of recovery, that the uninsured/underinsured motorist bears liability for the harmful event. The coverage extends only to situations in which the offending motorist lacks insurance or is inadequately insured; it does not apply when the owner or operator is cloaked with immunity from liability. In the latter event the insured cannot be regarded as one who, within the meaning of § 3636, stands "... legally entitled to recover damages from ...” the uninsured tortfeasor.3
*1114I would hold that the plaintiff-administra-trix does not have an actionable claim against her decedent’s UM carrier. The demand she presses here is not for a tort loss that is legally recoverable from the co-employee-driver. I would hence affirm the trial court’s summary judgment for the insurer.

In Hopkins v. Auto-Owners Insurance Company, supra, the court concluded that ”[b]ecause of *1114the exclusiveness of the workman’s compensation coverage, plaintiff never had a remedy against the tortfeasor" and to allow the plaintiff to recover “would be to grant ...a windfall not contemplated by the parties ... and not intended by the Legislature_" [Emphasis supplied.]
