This declaratory judgment action concerns the contractual liability of three insurance companies with respect to an underlying tort suit brought by Lyle Webb after he was injured while unloading an engine from his truck into David Roberts’ garage. In response to the parties’ motions for summary judgment, the superior court ruled that both Roberts’ automobile and homeowner insurers had a duty to defend and indemnify him. The court also ruled that the accident was not covered under Webb’s automobile policy, and it dismissed Webb’s bad-faith cross-claim against his insurer. Roberts’ homeowner’s insurer appeals, arguing that a coverage exclusion applies. 1 We agree and reverse.
On the evening of January 21, 1991, Webb drove his uninsured dump truck to Roberts’ home to drop off an engine for Roberts’ pickup truck. Webb’s visit was unexpected; apparently, Webb was repaying Roberts for some snowplowing Roberts had done for Webb. Because Roberts had no immediate use for the engine, he decided to store it in his garage. Webb backed his dump truck to the garage entrance, tilted the bed of the truck to facilitate unloading the engine, and opened the tailgate. In order to slide the engine to the garage floor, the two men placed a piece of plywood at the end of the tailgate to form a ramp. They attempted to slide the engine from the truck bed, down the plywood ramp, and onto the garage floor. Each man kept one foot in the bed of the truck and placed one foot on the plywood board. As they began to push the engine down the ramp, the *455 ramp slipped from its position, causing Webb to fall into the garage wall and onto the floor, where the engine rolled on his hand. Webb sued Roberts, claiming he was injured as the result of Roberts’ negligence in directing that the plywood be placed on an icy area of the garage floor.
At the time of the accident, three insurance policies were in force. Roberts had an automobile policy from State Farm Mutual Automobile Insurance Company that contained a provision covering liability for use of a nonowned vehicle. Roberts also had a homeowner’s policy from Cooperative Fire Insurance Company of Vermont that excluded coverage for liability resulting “directly or indirectly” from “the ownership, operation, maintenance, use, occupancy, renting, loaning, entrusting, supervision, loading or unloading by an insured of motorized vehicles.” Webb had an automobile policy issued by Nationwide Mutual Insurance Company that covered another truck he owned, but did not cover the dump truck involved in this litigation. That policy contains uninsured-underinsured motorist coverage.
In its summary judgment order, the superior court ruled that (1) State Farm was required to defend and indemnify Roberts under its nonowned-vehicle policy provision; (2) Cooperative Fire was required to defend and indemnify Roberts notwithstanding the automobile exclusion in its homeowner’s policy because one of the alleged causes of the accident was an included risk — ice on the garage floor; and (3) Nationwide was not required to extend uninsured-motorist coverage to the claim, and thus did not act in bad faith in denying coverage, because it did not insure Webb’s dump truck, and Roberts was an insured motorist. Only Webb and Cooperative Fire appealed from the order.
Following the declaratory judgment ruling, Webb’s tort suit went to trial and resulted in a defendant’s verdict, which was affirmed on appeal to this Court. The resolution of the underlying suit has mooted the dispute over whether Nationwide was required to extend uninsured-motorist coverage to Webb’s claim. It has also mooted any dispute over Cooperative Fire’s obligation to indemnify Roberts. There remains, however, a live dispute over the cost of the defense of the underlying suit between State Farm and Cooperative Fire. We must, therefore, decide Cooperative Fire’s appeal of the superior court’s decision that Cooperative Fire had an obligation to defend Roberts.
The issue turns on whether the doctrine of concurrent causation applies in light of the language of the policy and the facts *456 surrounding the accident. Under that doctrine, if the liability of an insured arises from concurrent but separate nonvehicle-related and vehicle-related negligent acts, and the nonvehicle-related act is an included risk under the insured’s homeowner’s policy, coverage exists even though the policy contains an automobile exclusion. 7A J. Appleman, Insurance Law and Practice § 4500, at 179-80 (1979). In other words, if an occurrence is caused by a risk included within the policy, coverage may not be denied merely because a separate excluded risk was an additional cause of the accident. Id. at 179.
The leading case on the concurrent causation doctrine is
State Farm Mutual Automobile Insurance Co. v. Partridge,
Here, ... an insured risk (the modification of the gun) combined with an excluded risk (the negligent use of the car) to produce the ultimate injury. Although there may be some question whether either of the two causes in the instant case can be properly characterized as the “prime,” “moving” or “efficient” cause of the accident we believe that coverage under a liability insurance policy is equally available to an insured whenever an insured risk constitutes simply a concurrent proximate cause of the injuries.
Id. at 130 (footnotes omitted).
In applying this holding to a variety of fact patterns in later cases, the California appellate courts have focused on whether the act that gave rise to the alleged liability under the homeowner’s policy was independent of the act that constituted use of the vehicle. See, e.g.,
Daggs v. Foremost Ins. Co.,
Although Cooperative Fire argues that we should not adopt the concurrent-causation doctrine, at least not in light of the wording of its policy, it urges alternatively that we embrace a restatement of the elements of the doctrine in
Garvey v. State Farm Fire & Casualty Co.,
The California Supreme Court affirmed
Garvey,
but did not explicitly adopt the district court’s analysis, because it refused to extend
Partridge
to first-party property-loss cases, stating that
Partridge
“should be utilized only in
liability
cases in which true concurrent causes, each originating from an independent act of negligence, simultaneously join together to produce injury.”
Garvey v. State Farm Fire & Casualty Co.,
Courts in several other jurisdictions have adopted the concurrent-causation doctrine set forth in
Partridge,
although there has been no consensus on the legal test for determining when included and excluded causes are sufficiently independent to invoke the doctrine. For the most part, determination of whether coverage exists has been
*458
heavily dependent on the particular facts of each case. See, e.g.,
Waseca Mut. Ins. Co. v. Noska,
Some courts, however, have refused to apply the concurrent-causation doctrine so as to nullify an unambiguous automobile exclusion that denies coverage for occurrences arising out of the use of a motor vehicle. See
Northern Assurance Co. of America v. EDP Floors, Inc.,
*459
On at least two occasions, we have addressed the effect of multiple causes of an accident on insurance coverage for damages arising out of that accident. In
Town of South Burlington v. American Fidelity Co.,
Similarly, in
Valente v. Commercial Insurance Co.,
Although neither Valente nor South Burlington explicitly adopted the concurrent-causation doctrine, the opinions are consistent with use of that doctrine. We conclude that the concurrent-causation doctrine is a logical extension of our precedents and adopt it for determining whether liability coverage is excluded by a use exclusion of the type involved here.
Cooperative Fire argues that despite our adoption of the concurrent-causation doctrine, it should not apply in this case because (1) its automobile exclusion unambiguously and broadly denied coverage for injuries “directly or indirectly” associated with motor vehicles, and thus the court’s application of the doctrine effectively rewrote the insurance contract between it and Roberts; (2) the exclusion is *460 consistent with the reasonable expectations of the parties to the contract; and (3) the ice was not an independent cause of the injuries because the same loss could not have occurred absent the excluded risk and the included risk did not set in motion the excluded risk. We take these arguments in turn.
As Cooperative Fire points out, courts adopting the concurrent-causation doctrine have construed automobile exclusions containing the phrase “arising out of” rather than the instant phrase “results directly or indirectly from.” We see no significant difference in the meaning of the phrases, however. Indeed, the courts have acknowledged the breadth and lack of ambiguity in the “arising out of” exclusion language. See
Lawver,
In so holding, we do not depart from our oft-stated principle that insurance contracts “must be interpreted according to their terms and the evident intent of the parties, as gathered from the contract language.”
Cooperative Fire Ins. Ass’n v. Gray,
The reasonable expectations of the parties are important in considering the scope of coverage provided in insurance contracts because such contracts, largely adhesive in nature, often contain boilerplate terms that are not bargained for, not read, and not understood by the insureds.
Darner Motor Sales, Inc. v. Universal Underwriters Ins. Co.,
The purpose of Cooperative Fire’s policy “was to insure other liabilities outside the area of motor vehicles.”
Medlar v. Aetna Ins. Co.,
Finally, we must determine whether the superior court correctly applied the doctrine of concurrent causation to this case to find that Cooperative Fire had a duty to defend. As stated above, Cooperative Fire’s main argument on this point is that the concurrent causes should be independent of each other, as set out in the court of appeals’ decision in Garvey, and that requirement is not met. In addressing this question, we first emphasize that this is not truly a concurrent-causation case. Webb has not alleged that Roberts was negligent in any respect other than directing the placement of the plywood ramp on the ice-covered floor. The concurring cause, if it can be described as such, was the unloading of the engine from the truck bed and down the ramp. There is no allegation that any negligence was involved in the unloading operation, apart from the placement of the ramp.
These facts are comparable to those in Daggs v. Foremost Insurance Co., where the tort plaintiff was injured, while participating in a motorcycle race, when he ran into the chain-link barrier fence surrounding the race course. The course-owners’ liability carrier denied coverage under a policy exclusion for injuries arising out of the use of mobile equipment while being used in organized racing. The insured alleged that the negligent design of the fence was a concurrent cause under Partridge. The court disagreed, stating:
The only reasonable interpretation of the allegations of plaintiff’s underlying complaint is that [insured] failed to make the motorcycle course safe for the organized racing event in which plaintiff was participating. There is but one negligent act of the insured, not two as in Partridge, and this cause of the injuries is not independent of the policy exclusion.
*463
Webb’s real complaint against Roberts was that Roberts made the act of unloading the engine unsafe by placing the plywood ramp on the ice. It is the unloading of the truck that is explicitly excluded from the policy coverage. We are unable to separate the alleged act of negligence from the policy exclusion. We agree with the California courts that the negligence on which coverage is premised must somehow be independent of the conduct excluded from the policy. Accordingly we hold that concurrent causation does not apply and the superior court erred in finding coverage under Cooperative Fire’s policy.
Reversed.
Notes
Webb also appealed, arguing that he was entitled to uninsured-motorist coverage under his automobile policy. Because the underlying suit has been resolved adversely to Webb, this appeal is moot, and we do not consider it.
If the insured is seeking coverage against loss or damage sustained by the insured, the claim is first party in nature; on the other hand, if the insured is seeking coverage against liability of the insured to another, the claim is third party in nature.
