The defendants appeal from a summary judgment entered in favor of the plaintiff, Quincy Mutual Fire Insurance Company (insurer), by a judge of the Superior Court. The insurer had instituted an action for declaratory relief, seeking a judgment that the injuries sustained by the defendants Brooke and Ellen Abernathy fell within an exclusion clause of a homeowner’s policy carried by the defendants Harold and Annette Hannon thereby relieving the insurer of any liability under the policy. The Abemathys and the insurer filed cross motions for judgment on the pleadings or, in the alternative, for summary judgment, on a statement of agreed facts. See Mass. R. Civ. P. 12 (c), 56 (c),
The relevant facts, as presented by the parties’ pleadings and the statement of agreed facts, are as follows. On November 10,1979, at approximately 7 p.m. , Ellen Abernathy was driving in her car. Her daughter, Brooke, was a passenger in the rear seat. James Hannon, sixteen years old at the time of the incident, admitted to throwing a large piece of “blacktop” at the car. The rock shattered the window on the driver’s side of the car and caused the driver, Ellen Abernathy, to sustain facial cuts. The blacktop travelled to the rear seat where it struck Brooke Abernathy in the forehead. Brooke suffered a fractured skull.
On February 7, 1980, the Springfield Juvenile Court adjudicated James Hannon a delinquent as a result of the charge against him of assault and battery by means of a dangerous weapon. Ellen and Brooke Abernathy have commenced suit *83 against James Hannon seeking to recover for personal injuries and expenses incurred.
At the time of the incident, James Hannon’s parents had a contract of insurance in effect with the insurer. The policy was entitled “Homeowners Policy — Comprehensive Personal Liability.” James Hannon is an “insured” under the policy, which defines an insured as any resident “of the named insured’s household . . . and any other person under the age of twenty-one in the care of any insured.” Under the relevant terms of the policy, the insurer agreed to pay damages for which the insured became personally liable and all reasonable medical expenses “to or for each person who sustains bodily injury to which this insurance applies, caused by an accident, if such bodily injury is caused by the activities of any insured.” An exclusion clause of the policy provides that “[t]his policy does not apply ... to bodily injury or property damage which is either expected or intended from the standpoint of the Insured. ”
The Appeals Court correctly noted that “[ejxclusions from [insurance] coverage are to be strictly construed.”

v.
Abernathy, supra
at 908, quoting
Vappi & Co. v. Aetna Casualty & Sur. Co.,
The insurance policy in issue provides coverage for liability imposed on the insured where a person has sustained bodily injury by “accident.” The word “accident” has been held to be a word that should be broadly construed.
Beacon Textiles Corp.
v.
Employers Mut. Liab. Ins. Co.,
Ordinarily, injury recklessly caused has been viewed as being within the ambit of coverage for injuries suffered by “accident.” See Sheehan v. Goriansky, supra. Here, however, there is in the exclusion clause language wherein the insurer disclaims liability for “bodily injury. . . which is . . . expected . . . from the standpoint of the Insured.” It is arguable that the insurer intended a different meaning to attach to the word “expected” by virtue of the disjunctive used in the exclusion clause, denying coverage for injuries “either expected or intended” (emphasis supplied).
The word “expected” is ambiguous in legal signification. No Massachusetts case has construed directly the meaning of the word “expected” in an insurance policy exclusion clause.

Some courts have construed similar clauses involving the word “expected” to mean more than a reasonably foreseeable injury resulting from an intentional act, i.e., from negligence. See
Carter Lake
v.
Aetna Casualty & Sur. Co.,
Other courts have interpreted the word “expected” in insurance policy subclauses to mean that the insured knew or should have known that there was a “substantial probability” that certain results would ensue. Such an approach would appear to require proof of at least recklessness. Cf.
Auto-Owners Ins. Co.
v.
Jensen,
*86 The difficulty that courts have had with the definition of the word “expected” in this context leads us to the conclusion that we should resolve the ambiguity of this language against the insurance company. Cf. Vappi & Co. v. Aetna Casualty & Sur. Co., supra at 431-432. Our cases have concluded that an injury is nonaccidental only where the result was actually, not constructively, intended, i.e., more than recklessness. Sheehan v. Goriansky, supra at 204-205. This standard requires a showing that the insured knew to a substantial certainty that the bodily injury would result. Thus, we conclude the word “expected” brings no change to our well-defined concept of “accident.” Had the insurer intended a different result, it could have used more appropriate language in the exclusion clause.
After considering the definitions of the terms “intended” and “expected” as they appear in the Hannons’ exclusion clause, we cannot conclude that the insurer sustained its burden of proving the absence of a genuine issue of material fact from the pleadings and the statement of agreed facts. See

It is the function of the judge, in ruling on the summary judgment motion, to look beyond the formal allegations of fact in the pleadings “and to determine whether further exploration of the facts is necessary.”
Hahn
v.
Sargent, supra
at 464, citing
Briggs
v.
Kerrigan,
By denying that James Hannon intentionally sought to injure the Abemathys when he threw the rock at their car, the defendants’ answers presented a factual issue concerning Hannon’s state of mind when he engaged in this action. The statement of agreed facts presented only the following new and relevant information: the incident occurred at 7 p.m. on November 10, 1979; Ellen and Brooke Abernathy were “riding” in their car at the time; the car was struck by a large piece of blacktop which shattered the windshield on the driver’s side and travelled to the rear seat; and James Hannon “admitted to throwing the rock at” the Abemathys’ car.
These undisputed facts do not resolve either of the two crucial issues raised by the pleadings: whether Hannon intended, by his volitional act, to cause injury to the Abemathys or whether he knew to a substantial certainty that such injuries would ensue from his actions. From the agreed facts, we know only that James Hannon admitted to performing the physical act of throwing the rock at the car. 4 The statement tells us nothing about sixteen year old Hannon’s state of mind at the time. We do not know whether his act was prompted by a desire to injure or merely to frighten the occupants of the car, *88 or whether he threw the rock as part of an adolescent prank. We know nothing about Hannon’s mental faculties at the time of the incident.
Furthermore, even if we assume that Hannon was fully aware of the circumstances when he threw the rock, the judge could not infer merely from the undisputed facts that he expected or intended harm to the Abemathys. When the incident occurred, the Abemathys were “riding” in their car, thus it may be assumed that Ellen Abernathy was driving the vehicle. The incident took place at about 7 p.m. in November, and therefore, presumably, in full darkness. However, there is no information on the lighting conditions of the road. Since we also do not know Hannon’s proximity to the car when he threw the rock one cannot infer that he saw, at night, a child sitting in the rear seat of the car.
The agreed statement also does not inform us of the relative size of the “large piece of blacktop” which he threw. We cannot conclude, therefore, whether the rock was the approximate size of a softball or whether it was nearer the size of a football or a basketball. Although the rock shattered the driver’s side of the windshield, the statement does not tell us whether Hannon aimed at the windshield, at the body of the car, or merely threw the rock in the general direction of the car.
The judge should have concluded that crucial factual issues concerning Hannon’s state of mind and the surrounding circumstances remained unresolved and required further exploration, see Hahn v. Sargent, supra at 464, before a determination could be made as to whether the incident fell within the exclusion clause of the insurance policy. Cf. Noyes v. Quincy Mut. Fire Ins. Co., supra at 126-727.
We conclude that the judge erred in ruling, as matter of law, that the Abemathys’ personal injuries were “either ex--pected or intended from the standpoint of the Insured” and thus excluded from coverage under the Hannons’ homeowner’s policy. The judgment of the Superior Court is reversed and the case is remanded for further proceedings.
So ordered.
Notes
Distinguishable from the present factual situation are insurance policies which restrict coverage to injuries which occur solely through external, violent, and accidental means. See
Kramer
v.
New York Life Ins. Co.,
The Appeals Court appears to have equated the definition of “expected” with that of “intended” for purposes of determining whether an incident falls within the exclusion clause. See
Quincy Mut. Fire Ins. Co.
v.
Abernathy,
Hannon’s adjudication of delinquency by virtue of committing an assault and battery by means of a dangerous weapon is neither conclusive nor admissible as to whether he knew that his actions would result in serious harm to the occupants of the car. A conviction of assault and battery by means of a dangerous weapon requires proof only that the defendant intentionally and unjustifiably used force, however slight, upon the person of another, by means of an instrumentality capable of causing bodily harm.
