In this action to collect under the death benefit provisions of an automobile insurance policy, plaintiff, Gloria Dilley, widow of the deceased insured, Carl *386T. Dilley, appeals from the judgment entered after the trial court granted defendant’s motion for summary judgment.
Carl T. Dilley was electrocuted during the course of his employment while stringing wire from a bucket attached to an hydraulic boom on a truck. Dilley was accompanied by his foreman and fellow Southern California Edison employee, John Barnett, who drove the truck to the job site and parked it. Neither truck, boom, nor bucket was in motion at the moment of electrocution.
This is not a workmen’s compensation case, but involves Dilley’s automobile insurance policy declaring coverage on his 1959 Rambler. The death benefit provisions of the policy promised: “ To pay the principal sum stated ... in event of the death of each insured which shall result directly . . . from bodily injury caused by accident and sustained by the insured while occupying ... an automobile. ...” The policy excluded death benefit coverage where “. . . bodily injury [was] sustained in the course of his occupation by any person while engaged ... in duties ... as an assistant on, a public or livery conveyance or commercial automobile.
The trial court determined Dilley was an assistant on a commercial automobile and granted defendant’s motion for summary judgment. Plaintiff contends whether Dilley was an assistant on a commercial automobile is a triable issue of fad ; the existence of a triable issue of fact precludes summary judgment (Code Civ. Proc., §437c). In the trial court, however, both plaintiff and defendant had moved for summary judgment.
Alt the oral proceedings on the motions for summary judgment, the following statements were made:
“Mb. Pike: (Defendant’s Attorney) . . . The matter is so clear that there is nothing possible for a jury to determine and it should be disposed of at this time.
“Mb. Giobdano: (Plaintiff’s Attorney) Yes, with that last statement of Counsel the plaintiff agrees. . . .
“The Court: What factual issues are you presenting?
“Mr. Giordano: We take the position that there are no factual issues. It is just a matter of interpretation of the policy, your Honor. We are agreed on all of the facts. This is a motion that I wish to set forth on behalf of the plaintiff. There is no dispute as to the facts. The Court then is faced with the problem of whether to grant the motion of the plaintiff or the defendant.
*387“The basic question . . . should then place the Court in a position to make a determination as a matter of law whether or not there was or was not an exclusion of this particular individual.
“Mr. Pike: I believe, your Honor, and I agree with Mr. Giordano, that there is no question of fact here. It can be decided as a matter of law.” (Italics ours.)
Having vigorously invited the trial court to determine coverage as a matter of law, plaintiff cannot now urge the trial court erred in doing so. (Pobor v. Western Pac. R.R. Co., 55 Cal.2d 314 [11 Cal.Rptr. 106, 359 P.2d 474]; Bondulich v. O. E. Anderson Co., 210 Cal.App.2d 12 [26 Cal.Rptr. 147]; Smith v. Royal Mfg. Co., 185 Cal.App.2d 315 [8 Cal.Rptr. 417] ; Cushman v. Cushman, 178 Cal.App.2d 492 [3 Cal.Rptr. 24].)
Dilley’s policy covered basically his Rambler. The death benefit provisions, however, extended coverage to fatal injury caused by accident and sustained while occupying an automobile; coverage was excluded if death resulted from certain automobile related activities in which the risk of injury is high. This area of exclusion included:
“(a) . . . bodily injury sustained in the course of . . . occupation by any person while engaged (1) in duties incident to the operation, loading or unloading of, or as an assistant on, a public or livery conveyance or commercial automobile, or (2) in duties incident to the repair or servicing of automobiles;....”
Both parties concede the truck is an automobile. Plaintiff contends the truck is not a commercial automobile. Because the exclusionary language “a public or livery conveyance or commercial automobile” is constructed disjunctively, plaintiff argues the types of vehicles described are synonyms of vehicles for hire. Plaintiff immediately concludes the truck upon which Dilley worked was not a commercial automobile because not a vehicle for hire. Plaintiff does not offer any reasons to explain why the disjunctive “or” requires this conclusion.
The word commercial usually describes commerce, trade, business, industry or enterprise having financial profit as a primary aim. (See 15A C.J.S. p. 1.) The truck upon which Dilley worked ivas an integral part of Southern California Edison’s commercial enterprise, a basic tool used in building, *388expanding and servicing the transit of power over power lines. A functioning tool of commerce, the truck was a commercial automobile within the meaning of the policy exclusion because of the high risk created when working on it. (See Pacific Employers Ins. Co. v. Maryland Casualty Co., 65 Cal.2d 318 [54 Cal.Rptr. 385, 419 P.2d 641]; Kirk v. Nationwide Mutual Ins. Co., 254 N.C. 651 [119 S.E.2d 645] ; Hardee v. Southern Farm Bureau Cas. Ins. Co., 127 So.2d 220.)
The trial court correctly determined the policy excluded coverage for Dilley’s death. Dilley was killed while occupying the truck in the course of his employment and engaging in duties as an assistant to the foreman on a commercial automobile.
Judgment affirmed.
