This appeal from a declaratory judgment primarily requires us to decide within the context of a claim for uninsured motorist benefits by an injured insured whether a tortfeasor’s intentional conduct may constitute an “accident” within the meaning of the uninsured motor vehicle provision of an insurance contract and whether the conduct giving rise to the injuries to the insured arose from the use of a motor vehicle. We also consider the binding effect of a judgment against the uninsured tortfeasor. The district court entered judgment for the insurer. It held the injuries to the insured arose from the use of a motor vehicle but the uninsured motor vehicle clause did not extend coverage to the insured for injuries caused by the intentional acts of a third-party tort-feasor. On our review, we affirm the judgment of the district court in part and reverse in part.
*574 I. Background Facts and Proceedings.
Dawn Petersen (Petersen) was injured on July 29, 1999, after she was assaulted by her former live-in boyfriend, David Ad-cock (Adcock), in his Chevrolet Blazer. Petersen was a passenger in the vehicle and Adcock was the driver. The most serious injuries occurred when Petersen jumped from the moving Blazer in an effort to escape the assaultive conduct by Adcock.
Petersen and Adcock lived together for several years and had a five-year-old son. Their relationship was marked by years of abuse, and Petersen had recently moved from the home they shared. Sadly, not unlike many other women who attempt to leave an abusive relationship, Petersen was stalked and terrorized by Adcock after she left, culminating in the events of July 29.
On that fateful day, Petersen met Ad-cock at a restaurant in the early evening hours to discuss issues involving their son. During the conversation in the restaurant, Adcock convinced Petersen to go with him to his Blazer parked outside of the restaurant under the ruse that he had a card to give her. Petersen entered the Blazer and sat in the front passenger seat. Adcock entered and sat in the driver’s seat. He started the car and rolled its windows down. Within minutes, Adcock began shocking Petersen with a stun gun. He also grabbed her around the neck. Ad-cock then drove from the restaurant as he continued to shock her with the stun gun.
After unsuccessfully attempting to grab the steering wheel from Adcock, Petersen climbed out of the window of the Blazer and eventually released her grip on the moving vehicle. She felt her life was in greater danger if she remained with the vehicle. Petersen sustained numerous injuries to her body when she struck the pavement of the street. The vehicle was traveling approximately forty miles per hour at the time. She also sustained injuries from the stun gun.
American Family Mutual Insurance Company (American Family) insured the Blazer by a policy of insurance in Adcock’s name. The liability provisions of the policy excluded coverage for “[bjodily injury ... caused by an intentional act of ... an insured person.” Petersen had a separate insurance policy with American Family covering her vehicle. This policy included uninsured motorist coverage. The provision provided:
We will pay compensatory damages for bodily injury which an insured person is legally entitled to recover from the owner or operator of an uninsured motor vehicle. The bodily injury must be sustained by an insured person and must be caused by accident and arise out of the use of the uninsured motor vehicle.
Petersen sued Adcock on March 3, 2000, for the injuries she received from the incident on July 29, 1999. Adcock promptly filed a pro se answer denying the claim. However, after Adcock failed to respond to discovery requests and failed to appear for a hearing on sanctions, the district court entered a default against him on November 14, 2000. Following a hearing on damages on February 8, 2001, the district court entered judgment against Adcock for $52,133.14 in compensatory damages and $35,000 in punitive damages.
American Family was not informed of the lawsuit against Adcock until December 13, 2000, and was not notified of the hearing on damages until February 1, 2001, one week prior to the hearing. American Family denied coverage under both insurance policies and elected not to seek intervention in the lawsuit to participate in the *575 damage hearing. After the final judgment was entered, Petersen requested American Family pay her damages pursuant to the uninsured motorist clause of her insurance policy.
American Family filed a petition for declaratory relief. It claimed there was no coverage for any damages sustained by Petersen under either American Family policy. It also claimed it was not bound by the judgment obtained by Petersen against Adcock. Petersen asked that the court declare coverage under both policies and find the default judgment binding on American Family.
The district court considered the petition on stipulated facts. It determined there was no coverage under the American Family policies. It first found that the intentional act exclusion precluded coverage under Adcock’s policy. It then found there was no coverage under the uninsured motorist provision of Petersen’s policy because Petersen’s injuries were not “caused by accident.” It did not address the question whether the judgment was binding on American Family. The district court later denied Petersen’s motion to enlarge the ruling to fully address all issues.
Petersen appeals and raises two issues. First, she asserts that the question whether an “accident” occurred under the uninsured motor vehicle provision should be considered from the viewpoint of the injured insured, not the uninsured tortfea-sor. From her viewpoint, Petersen claims the incident was unexpected and unintended, which makes her injuries accidental. Second, she argues American Family must be bound by the prior judgment against Adcock in a claim under the uninsured motorist clause of her insurance policy because American Family failed to intervene in the action after receiving notice of the damage hearing. American Family responds that both grounds it asserted at trial can support the decision of the district court. It also argues that the doctrines of res judicata and collateral estop-pel preclude enforcement of the judgment against it in the event coverage exists under the uninsured motorist clause.
II. Scope of Review.
A declaratory judgment action tried at law limits our review to correction of errors at law.
United Fire & Cas. Co. v. Shelly Funeral Home, Inc.,
III. Uninsured Motorist Coverage.
The uninsured motorist (UM) coverage of an insurance policy typically applies when four requirements are satisfied. 1 Two such requirements are that the bodily injury be caused by “accident” and that the bodily injury arise out of the “use” of the uninsured vehicle. These two requirements form the foundation for this appeal and require us to decide the meaning of *576 each phrase within the context of UM coverage.
Before separately addressing each requirement, we recognize that our fundamental task at hand is to interpret the language of the insurance policy.
See Gen. Cas. Co. of Wis. v. Hines,
IY. “Caused by Accident” Requirement.
The meaning of the term “accident” within the context of UM coverage and, in particular, whether the term can include intentional acts of an uninsured tortfeasor,
is an issue of first impression in Iowa. Other jurisdictions have answered the question differently depending upon whether an “accident” is viewed from the perspective of the injured insured or the uninsured tortfeasor. A majority of jurisdictions consider the question from the perspective of the injured insured, and conclude an intentional act of an uninsured tortfeasor may nevertheless be an “accident” under a UM provision as long as it was unprovoked by the injured insured.
See State Farm Mut. Auto. Ins. Co. v. McMillan,
First ... unless the tortious conduct of the uninsured or unidentified motorist was provoked by the injured person, the events and the injuries resulting from intentional acts are indistinguishable from those that result from negligent acts. In other words, when injuries are viewed from the vantage point of an injured person, the cause of the injuries is no less fortuitous than the situation in which a person is injured as a result of the negligent operation of an uninsured vehicle.
Second, since uninsured motorist insurance is a first party coverage, the insurance provides no benefits — directly or indirectly — to the tortfeasor. Indeed, if the tortfeasor is financially responsible, the insurer which has paid uninsured motorist insurance benefits may seek reimbursement for payments made to a claimant. Therefore, the claim for indemnification under uninsured motor *577 ist insurance is readily distinguished from situations involving a question about whether liability insurance covers claims for damages that result from intentional torts.
Third, the justifications for not indemnifying the insured who intentionally commits a tortious act relate to deterrence or punishment: considerations that do not apply to the payment of first party, uninsured motorist insurance claims. Uninsured motorist insurance benefits paid to an injured person do not reduce the possibility that the tort system or the criminal law system will operate either (a) to punish the tortfeasor or (b) to influence the conduct of the tortfeasor who caused the loss which is indemnified by the insurance or of other potential tortfeasors.
Fourth, the enactment of uninsured motorist insurance statutes throughout the country, which mandate either that the insurance be offered to all motor vehicle insurance purchasers or included in all motor vehicle insurance policies, reflects the importance attached to providing indemnification for innocent traffic victims who are injured by financially irresponsible or unidentified motorists.
1 Alan I. Widiss, Uninsured and Underin-sured Motorist Insurance § 10.2, at 655-56 (rev.2d ed.1999) (footnote omitted) [hereinafter Widiss].
The minority view generally defines the term “accident” from the perspective of the uninsured tortfeasor.
See McMillan,
In interpreting the “caused by accident” language of the UM provision in this case, we first observe that the insurance policy fails to define the word “accident.” When a word is left undefined in a policy, we give it the ordinary meaning a reasonable person would understand the word to mean.
Farm & City Ins. Co. v. Potter,
To determine the existence of an ambiguity, we begin by examining the purpose and intent of our UM statute. Although the intent of the parties controls the resolution of the issue, it is recognized that our UM statute forms' “a basic part of the policy” and must be considered to effectuate the parties’ intent.
Hollingsworth v. Schminkey,
The language of the UM clause of the insurance policy closely tracks the language of our uninsured motorist statute found in Iowa Code section 516A.1 (2001). This section requires all motor vehicle insurance policies that insure “against liability for bodily injury or death arising out of the ownership, maintenance, or use of a motor vehicle” to provide coverage:
for the protection of persons insured under such policy who are legally entitled to recover damages from the owner or operator of an uninsured motor vehicle ... because of bodily injury ... caused by accident and arising out of the ownership, maintenance, or use of such uninsured ... motor vehicle.
Id.
We have previously traced the concept of UM coverage back to a standard endorsement promulgated by the National Bureau of Casualty Underwriters in 1956, initiated as a response to the growing trend among the states to require liability insurance.
Douglass v. Am. Family Mut. Ins. Co.,
The specific purpose of UM coverage identified in
Douglass
could be viewed to support the notion that an accident in the context of UM coverage excludes intentional acts of the uninsured tortfeasor.
*579
See
Ytreberg,
However, we have also viewed our UM statute to be more than a mere substitution for a tortfeasor’s noncompliance with the financial responsibility laws. We have previously explained “ ‘[t]he purpose of uninsured motorist coverage is to ensure minimum compensation to victims of uninsured motorists.’ ”
Hamm,
We acknowledge our prior cases have adopted a “narrow coverage” view of uninsured-motorist coverage, in contrast with a “broad coverage” view of underinsured-motorist coverage.
Veach,
We next turn to consider the insurance policy as a whole, including other terms of UM coverage.
See Morgan,
The policy defines a “uninsured motor vehicle” to include not only an uninsured vehicle, but also a motor vehicle that is “insured by a bodily injury liability ...
*580
policy at the time of the accident but the company denies coverage.” This definition reveals that UM coverage applies not only when the tortfeasor’s motor vehicle is “not insured by a bodily injury liability ... policy” but also when, as in this case, the motor vehicle is insured but the insurer denies coverage. Clearly, the UM provisions contemplate coverage to include situations, like this case, when the victim could not recover under the tortfeasor’s liability policy due to an exclusion. Moreover, the policy identifies the circumstances when a vehicle will not be considered an uninsured motor vehicle. These circumstances did not include denial of coverage for intentional conduct.
See Iowa Comprehensive Petroleum Underground, Storage Tank Fund Bd.,
We next review the definition of the term “accident” in an effort to ascertain its reasonable meaning. We have previously considered the definition of “accident” in the context of the liability provisions of an automobile insurance policy. In
Potter,
we held a collision that occurred after the insured driver was unable to stop her vehicle was an “accident” under the terms of a liability policy, even though the insured intentionally severed the brake lines of the vehicle. We reached this conclusion because the insured nevertheless attempted to avoid the collision after the brakes failed.
See Potter,
[A]n ‘accident’ is an event which, under the circumstances, is unusual and unexpected by a person to whom it happens; the happening of an event without the concurrence of the will of the person by whose agency it is caused.
We also considered the definition of an “accident” in the context of a premise liability policy in
Central Bearings Co. v. Wolverine Insurance Co.,
Most recently, we considered the definition of an “accident” in
Austin v. CUNA Mutual Life Insurance Co.,
Two important points emerge from our prior cases. First, no single common definition of an “accident” applies to all types of insurance. Second, while we consider an “accident” to be an unusual and unexpected event, we have indicated that the event can be viewed through the lens of the tortfeasor, victim, and even a fictitious third party. Thus, these cases help expose the ambiguity that can arise from the use of the word “accident.” Nevertheless, none of our prior cases have accepted the position argued in this case that an “accident” takes place when the tortfeasor intended to harm the person or property damaged.
See Potter,
Liability coverage involves third-party coverage and exists as a form of indemnification to protect the insured from paying for damages the insured causes to others. In contrast, UM coverage is first-party coverage that serves not to indemnify, but to compensate the insured for injuries by uninsured motorists.
See Wendell,
We also think a distinction between intentional and negligent acts of an uninsured tortfeasor within thq context of UM
*582
coverage would lead to rather absurd and unintended results for blameless injured insureds.
See McMillan,
We conclude the term “accident” under a UM provision of an insurance policy can include the situation in which the injuries are caused by intentional conduct of an uninsured tortfeasor. The term is ambiguous due to the variant viewpoints of the participants to the event, and we consequently construe ambiguous terms in favor of coverage. Accordingly, we believe the term can properly be viewed from the perspective of a blameless insured. We think the important aspect of the definition is found in the element of surprise and misfortune, and these aspects of an event are still present when one party to the event had no intent to harm another or property of 'another, even though another party had such an intent. This approach is not inconsistent with our prior cases, but simply recognizes that an “accident” can occur when only one party to the event had the intent to harm the other, just as when neither party had any intent. This is consistent with our approach that an accident is “ ‘[a]n event which, under the circumstances, is unusual and unexpected by a person to whom it happens.’ ”
Comfort,
Based on the undisputed facts and arguments of the parties, Petersen did not' intend or provoke the injuries caused by Adcock’s sudden and unexpected assault. Accordingly, the incident causing injuries to Petersen was an “accident” under the UM provision of the policy. 2
V. “Arising Out of the ... Use of an Uninsured Motor Vehicle.”
We have previously considered the meaning of the phrase “arising out of’ in the context of UM provisions of an insurance policy substantially identical to the UM provision at issue in this case. In
Hollingsworth,
we indicated the phrase should be broadly construed and that it only requires “some causal relationship between injury and risk for which coverage is provided.”
From an analytical standpoint, we observe that the “arising out of’ phrase is tied directly to the phrase “use of the vehicle.” Nevertheless, these two phrases actually require separate inquiries.
See
8 Couch § 119:37, at 119-57 (“[T]he concepts of use and legal cause should be analyzed separately, avoiding the traditional proximate cause concepts.”). This means the use of the vehicle at the time of the injury must not only be a contemplated use and inherent in the purpose and nature of vehicles, but the use must be causally related to the injury.
See Johnson v. State Farm, Mut. Auto. Ins. Co.,
The district court found UM coverage applied because Petersen was a passenger in the uninsured vehicle being driven by Adcock, and she was injured while attempting to escape from the vehicle to avoid the assaultive actions of Adcock. American Family asserts the vehicle served as nothing more than the situs of a crime, and the cause of Petersen’s injuries was the criminal acts of Adcock and the contact of her body with the pavement of the street after she jumped from the vehicle.
We agree with American Family that the vehicle was merely the situs of the initial assault perpetrated on Petersen while it was in the parking lot.
See U.S. Fidelity & Guar. Co. v. Lehman,
We acknowledge the causal link between the use of the vehicle and the injuries suffered can be difficult to establish when intentional acts or crimes are involved.

Use”
of Insured Vehicles,
VI. Binding Effect of the Judgment.
The final issue on appeal is whether American Family may relitigate the issue of tort liability and damages. The district court passed upon the issue after finding there was no UM coverage under the policy. Because we determine there was cov *584 erage, we address the issue presented and preserved by American Family at trial.
We begin by turning to the language of the insurance policy. Under the uninsured motorist provision, American Family was obligated to pay damages for bodily injury which the insured “is legally entitled to recover” from the uninsured motorist or owner. Petersen argues the prior default judgment obtained against Adcock establishes her legal entitlement to recover and requires American Family to pay the damages specified in the judgment pursuant to the terms of the policy. American Family attempts to avoid the policy language by relying upon the doctrines of res judicata and collateral estoppel. It argues the pri- or judgment obtained by Petersen against Adcock cannot be used against it because it was not a party to the action and had no duty to defend Adcock, had inadequate notice of the proceedings, and the judgment did not constitute an actual litigation of the same issues that would be presented in an uninsured motorist claim. American Family relies secondarily on the policy provision requiring the insured to give notice of any suit against the uninsured motorist and to obtain the insurer’s “written consent to be bound by any resulting judgment.”
In considering the binding effect of the judgment, we are mindful that the issue is presented only in the context of an action to enforce the UM provisions of an insurance policy requiring the insurer to pay the insured damages which the insured “is legally entitled to recover” from the uninsured motorist. Consequently, the binding effect of the tort judgment at issue in this case is not necessarily governed by the doctrine of res judicata and collateral estoppel; the language of the contract between the parties is the primary source of the parties’ respective rights.
See generally
2 Widiss § 28.12, at 553-54. If an insured establishes legal entitlement to damages against an uninsured motorist, then the insurer is contractually obligated to pay the insured the damages as specified in the insurance policy. An insured generally satisfies the “legally entitled to recover” condition of UM coverage when a valid judgment has been entered against the uninsured motorist.
3
See Mizer v. State Auto. & Cas. Underwriters,
Although a valid judgment can establish a legal entitlement to recover for the purposes of UM coverage, the UM coverage provisions impose other conditions that *585 could require relitigation of the issues of liability and damage in a claim for UM benefits. First, the policy in this case limits recovery to bodily injury caused by accident and “arising] out of the use” of the uninsured vehicle. Second, the policy requires the insured to “notify” the insurer of a suit against an uninsured motorist to determine liability or damages, and further provides that the insurer is not bound by any judgment without its “consent” to the suit.
Initially, we recognize that some of the damages awarded under the judgment represent bodily injuries suffered by Petersen that were not covered under the policy. Although the most serious injuries arose from the use of the vehicle, the initial injuries from the assault did not arise from the use of the vehicle. Thus, the damages awarded under the judgment cannot be used to establish the damages under the policy. The remaining question is whether the issue of liability must also be relitigated based on the claim by American Family of inadequate notice. (Because we find this issue dispositive, we do not consider the effect of the policy’s consent-to-sue provision.)
It is generally recognized that a notice-of-suit clause in a UM policy of insurance is enforceable by the insurer and that the insurer is not bound by a judgment in a tort action against an uninsured motorist if the insurer did not receive adequate notice of the suit. See generally 2 Widiss § 28.12, at 545-58. Notice to the insurer is needed to give the insurer the opportunity to seek intervention in the tort action so that it can protect its potential interests and prevent any collusive judgments. It would also make it more likely for the parties to reach a resolution of all issues in a single proceeding.
The parties in this case agree that notice was given, but dispute whether it was timely and adequate under the circumstances. The district court made no findings on the issue and the stipulated facts and other documents submitted to the district court did not address the circumstances bearing on the adequacy or inadequacy of the notice provided. Moreover, there was no evidence concerning the issue of prejudice to the insurer. When provisions of an insurance policy establish conditions precedent to coverage, “an insured must show substantial compliance with [those] conditions.”
Simpson v. United States Fid. & Guar. Co.,
The record in this case is insufficient to establish substantial compliance with the notice provision. Notice to an insurer of a pending lawsuit against an uninsured tort-feasor after entry of judgment on liability would ordinarily be inadequate to fully protect the interests of the insurer, and the minimal record in this case does not allow a contrary conclusion or a conclusion that the insurer was not prejudiced by the notice provided. Accordingly, American Family is entitled to a declaratory judgment that the default judgment entered against Adcock is not binding on American Family.
VII. Conclusion.
The injury to Petersen was both caused by accident and arose out of the use of an uninsured motor vehicle. The district court erred in concluding the injury was not caused by accident. In addition, the insurer is not bound by the judgment entered in the insured’s suit against the uninsured motorist.
*586 AFFIRMED IN PART AND REVERSED IN PART.
Notes
. UM coverage is mandated when: (1) the injured person is an insured under the insurance policy provisions; (2) the injured person is "legally entitled to recover damages from the owner or operator of an uninsured motor vehicle;” (3) the injury to the insured was "caused by accident;” and (4) the injury arose "out of the ownership, maintenance, or use” of an uninsured motor vehicle. Iowa Code § 516A.1 (2001). These requirements are found both in our statute and the particular insurance policy at issue in this case.
. American Family,made no argument that Petersen’s own act ih jumping from the vehicle was an intentional cause of her injuries.
See Kirkpatrick v. AIU Ins. Co.,
. The “legally entitled to recover” requirement means the insured has the burden to prove the uninsured motorist was liable and the extent of the damages. This burden can be satisfied either in an action against the uninsured motorist or in an action against the insurer.
