Opinion

TOBRINER, J.

In this case we must determine whether, under California law, a school district may ever be held liable when, as a result of school authorities’ negligent supervision of students on school premises, a pupil leaves the school grounds during school hours and is subsequently injured by a motorist. Although the trial court held that a school district, incurs no liability under such circumstances as a matter of law, we have concluded that the trial court was in error and that, if plaintiffs can prove that the pupil’s injury was proximately caused by the school district’s negligent supervision, the district may be held liable for the resultant damages.

In the summer of 1974 plaintiff Michael Hoyem, a 10-year-old boy, attended summer school at Foster A. Begg School in defendant school district. On July 16 Michael arrived at school to attend classes but before the end of scheduled classes he left the school premises. At a public intersection a motorcycle struck Michael and he was seriously injured. A few hours after the accident plaintiff Mary Ann Hoyem, Michael’s mother, saw him in the hospital and suffered emotional and physical injuries.

Thereafter, Michael and his mother, alleging that the accident and resulting injuries were proximately caused by the school district’s negligent supervision, instituted the present action against the school district.¹ In the third amended complaint Michael sought recovery for the injuries he sustained in the accident, and his mother sought to recover (1) moneys she had expended for Michael’s medical care, (2) damages to compensate her for the loss of Michael’s “comfort and society,” and (3) damages for the physical and emotional injuries she suffered on viewing Michael in his injured state at the hospital. The trial court sustained defendant’s demurrer to all causes of action and dismissed the action; plaintiffs now appeal from the resulting judgment.

As we explain, the trial court erred in dismissing the causes of action seeking to recover damages for Michael’s injuries and medical expenses allegedly caused by the school district’s negligence. The causes of action based upon Maiy Ann’s loss of Michael’s “comfort and society” and her own injuries allegedly incurred when viewing Michael in the hospital are, however, precluded by recent decisions of this court and were properly dismissed by the trial court.

1. A school district bears a duty to supervise students while on the school premises during the school day and the district may be held liable for a student’s injuries which are proximately caused by the district’s failure to exercise reasonable care under the circumstances.

Although a school district is not an insurer of its pupils’ safety (Taylor v. Oakland Scavenger Co. (1938) 12 Cal.2d 310, 317 [83 P.2d 948]), our cases have long established that a school district bears a legal duty to exercise reasonable care in supervising students in its charge and may be held liable for injuries proximately caused by the failure to exercise such care. (E.g., Taylor v. Oakland Scavenger Co., supra, 12 Cal.2d 310; Pirkle v. Oakdale Union etc. School Dist. (1953) 40 Cal.2d 207 [253 P.2d 1]; Satariano v. Sleight (1942) 54 Cal.App.2d 278, 282-285 [129 P.2d 35]. See generally Annot. (1971) 38 A.L.R.3d 830.)

We recently reaffirmed this rule in Dailey v. Los Angeles Unified Sch. Dist. (1970) 2 Cal.3d 741, 747 [87 Cal.Rptr. 376, 470 P.2d 360], declaring that “California law has long imposed on school authorities a duty to ‘supervise at all times the conduct of the children on school grounds and to enforce those rules and regulations necessary to their protection.’ [Citations.] The standard of care imposed upon school personnel in carrying out this duty to supervise is identical to that required in the performance of their other duties. This uniform standard to which they are held is that degree of care ‘which a person of ordinary prudence, charged with [comparable] duties, would exercise under the same circumstances.’ [Citations.]”

In Dailey, two unsupervised high school students engaged in “slap-boxing” in the school gym during lunch hour, and as a result, one of the students fell, struck his head, and died shortly thereafter. “Slap-boxing” is a rough and forbidden game which, according to the testimony of other students, was never played when a teacher was nearby. In reversing a directed verdict in favor of defendant school district, this court held that the issues of whether or not the school acted negligently in failing to provide adequate supervision of the lunch hour recess and, if so, whether the student’s injuries were proximately caused by such negligence, fell within the province of the jury.

The pleadings in the instant case are virtually identical to those which our court found sufficient to state a cause of action in Dailey. In both cases the complaint alleged that the school district failed to exercise ordinary care in supervising a student while the student was on school premises, and that such negligence proximately caused the student’s resulting injuiy. Under well established principles, such general allegations of negligence, proximate causation and resulting injury and damages suffice to state a cause of action (see 3 Witkin, Cal. Procedure (2d ed. 1971) Pleading, §§ 450, 465, pp. 2103, 2119-2120); the court therefore improperly sustained defendant’s general demurrer. Although defendant presents several arguments in an attempt to distinguish Dailey and related authorities, none of the proposed distinctions withstands analysis.

Defendant district first contends that the duty to supervise pupils applied in Dailey and earlier cases does not include any responsibility for assuring that pupils remain on the school premises during the school day. As the Dailey court pointed out, however, the duty to supervise includes the duty “to enforce those rules and regulations necessary [for pupils’] protection.” (2 Cal.3d at p. 747.) Title 5, California Administrative Code, section 303 provides: “A pupil may not leave the school premises at recess, or at any other time before the regular hour for closing school, except in case of emergency, or with the approval of the principal of the school.” We have no doubt that this rule is at least in part for the pupils’ protection, and that the school authorities therefore bore the duty to exercise ordinary care to enforce the rule.

Defendant argues, however, that no California case has as yet held a school district liable for an injuiy incurred off school premises. Viewing the situs of the injury as a limitation on the school district’s duty to supervise, defendant contends that while a school district may be obligated to exercise reasonable care to prevent on-campus injuries, it bears no similar duty to supervise students so as to prevent off-campus accidents, unless the school has specifically undertaken to provide off-campus supervision.

In the first place, defendant’s broad assertion that no California decision has held a school district liable for an off-school premises injury is simply inaccurate. In Satariano v. Sleight, supra, 54 Cal.App.2d 278, a high school athletic field was located across a public street from the school gymnasium, and a 17-year-old student, hit by an automobile as he was crossing the street to get to the athletic field, suffered serious injuiy. The student brought suit against the school district, claiming that the school authorities’ negligent supervision proximately caused his injuries. The evidence at trial indicated that although school authorities were aware that students regularly ran across the street outside of the crosswalk and when a teacher happened to be present the teacher would warn students to correct their behavior, the school had taken no general steps to prevent such dangerous conduct, such as stationing a teacher by the street during appropriate times.

The trial court in Satariano took the view that the school authorities’ duty of supervision “ceased once the child was on a public street” (54 Cal.App.2d at p. 284) and consequently absolved the school district of all liability for the student’s injuries. On appeal, however, the Court of Appeal reversed, holding that in light of the school authorities’ knowledge that many students regularly crossed the public street outside of a crosswalk, the jury should have been permitted to determine whether “ordinary care for [the students’] protection did not require of the school authorities something more than sporadic warnings to individuals and groups in those accidental instances when teachers happened to be present.” (Pp. 284-285.) Thus, Satariano refutes defendant’s claim that the off-premises location of an injury is always sufficient, in itself, to insulate school officials from liability.

In addition to demonstrating that the off-campus situs of an injury does not ipso facto bar recovery from a school district, Satariano illustrates that, at least in some limited instances, school authorities may bear a responsibility for supervising students when they are not on school property. (See also Raymond v. Paradise Unified School Dist. (1963) 218 Cal.App.2d 1, 10-11 [31 Cal.Rptr. 847]; Lehmuth v. Long Beach Unified Sch. Dist. (1960) 53 Cal.2d 544, 551-552 [2 Cal.Rptr. 279, 348 P.2d 887].) In the instant case, however, we have no occasion to probe the scope of school authorities’ “off premises” supervisory duty, for in this case defendant’s alleged negligence relates to the district’s firmly established duty to exercise due care in supervising Michael while he was on school premises.

In this context, defendant’s emphasis on the situs of the injury is totally misplaced. Contrary to defendant’s assertion, no California decision suggests that when a school district fails to properly supervise a student on school premises, the district can automatically escape liability simply because the student’s ultimate injury occurs off school property. (Cf. Calandri v. Ione Unified School Dist. (1963) 219 Cal.App.2d 542, 549-550 [33 Cal.Rptr. 333] (school district liable for injury student sustained at home as a result of dangerous instrument made in shop class).) Thus, in reversing the trial court decision in this case we neither impose a new duty on school districts nor in any way extend the well-established rule reiterated in Dailey, we merely reaffirm that school districts must exercise reasonable care in supervising their pupils while the pupils are on school premises. A district may be held liable if its breach of that duty proximately causes a student’s injury.

The recent case of Bryant v. United States (10th Cir. 1977) 565 F.2d 650 confirms our conclusion that defendant’s potential liability under the facts of this case flows directly from a school district’s familiar duty to exercise ordinary care in supervising students on school premises. In Bryant, three young students at a New Mexico boarding school left the school premises without permission and were subsequently trapped in a snowstorm; as a result, the youngsters suffered extreme frostbite, necessitating the amputation of each student’s legs. The students subsequently sued the federal authorities who ran the school, alleging that the injuries were proximately caused by the school’s negligent supervision, and the jury returned a substantial verdict in favor of the students.

On appeal, the Tenth Circuit Court of Appeals affirmed the judgment. The court pointed out that under the governing New Mexico law, as in California, although “school authorities do not have responsibility for protective supervision at all places and under all circumstances” (565 F.2d at p. 652), “school authorities [do] have the duty to exercise ordinary care in protecting and supervising students while they are on school grounds. [Citations.]” (Italics added.) (Id.) Because the evidence in the case established that the school authorities had failed to provide adequate supervision while the students were playing outside of the school dormitories, permitting plaintiffs to run away from the school, the court concluded that the jury could properly conclude that the authorities had breached their duty to provide reasonable “on school ground” supervision and that the school’s negligence in this regard was a proximate cause of the students’ injuries. In light of the similarity between the applicable New Mexico and California law, the Bryant decision directly supports our conclusion that plaintiff’s complaint states a cause of action against defendant district.

In support of its contention that the off-premises situs of plaintiff’s injuries should absolve it of all responsibility, defendant relies on Education Code section 44808 (formerly § 13557.5) which provides, in relevant part: “[N]o school district. . . shall be responsible or in any way liable for the conduct or safety of any pupil of the public schools at any time when such pupil is not on school property, unless such district, . . . has undertaken to provide transportation for such pupil to and from the school premises, has undertaken a school-sponsored activity off the premises of such school, has otherwise specifically assumed such responsibility or liability or has failed to exercise reasonable care under the circumstances. . . .” Although defendant contends that this statute cloaks the school with a blanket immunity for off-campus injuries unless the school undertakes to furnish off-campus supervision or sponsors an off-campus activity, neither the language nor the legislative history of the statute supports such an interpretation.

First, the language of the statute itself specifies that its limitation on liability does not apply to the allegations of the instant complaint. Although the initial portion of the statute provides that “no school district shall be responsible ... for the conduct or safety of any pupil... at any time when such pupil is not on school property,” the section goes on explicitly to withdraw this grant of immunity whenever the school district, inter alia, “has failed to exercise reasonable care under the circumstances. ”² Plaintiffs’ complaint alleges that the school district failed to exercise reasonable care. Assuming, as we must on appeal from a sustained demurrer, the truth of the allegations of the complaint (see, e.g., Harman v. City and County of San Francisco (1972) 7 Cal.3d 150, 165 [101 Cal.Rptr. 880, 496, P.2d 1248]; Daar v. Yellow Cab Co. (1967) 67 Cal.2d 695, 713 [63 Cal.Rptr. 724, 433 P.2d 732]), section 44808, by its own terms, does not bar liability in the present case.

Second, the decisional history preceding the enactment of section 44808 indicates that the Legislature intended to limit a school district’s liability under very different circumstances than those presented here. Two Court of Appeal cases, Kerwin v. County of San Mateo (1959) 176 Cal.App.2d 304 [1 Cal.Rptr. 437] and Girard v. Monrovia City School Dist. (1953) 121 Cal.App.2d 737 [264 P.2d 115], which preceded the enactment of the section and upon which defendant relies heavily, demonstrate that the Legislature was principally concerned with limiting a school district’s liability for injuries to pupils either before or after school hours while children were either going to school or coming home after school.

In Kerwin, a six-year-old boy became ill at school. A school official telephoned the boy’s home and, finding no one at home except the boy’s eleven-year-old brother, asked the brother to come and take the six-year-old home. The school subsequently released the six-year-old to his brother, an;d on the boys’ way home the eleven-year-old, who did not attend the younger brother’s school, incurred injury. In denying recovery to the injured plaintiff, the Court of Appeal observed in dictum that even with respect to its own pupils “[a] school district is under no duty to supervise, or provide for the protection of its pupils, on their way home, unless it has undertaken to provide transportation for them. . . .” (176 Cal.App.2d at p. 307.) (Italics added.) Thus, the language in Kerwin relied upon by defendant simply declared that a school district is not legally responsible for accidents en route once pupils have been released from school, or before they arrive at school. The Legislature, in borrowing from the Kerwin language for section 44808, apparently intended to limit a district’s liability under similar circumstances.

In Girard, also relied on by defendant, the court denied recovery under circumstances analogous to Kerwin. In Girard a boy was killed in a traffic accident on his way home from school. The complaint alleged that defendant school district negligently enrolled the child in the wrong school, causing him to cross heavily traveled streets on his way home from school. Like Kerwin, Girard held that a school district has no responsibility to see that children travel safely to and from school unless it undertakes to provide transportation. (See also Wright v. Arcade School Dist. (1964) 230 Cal.App.2d 272, 279-280 [40 Cal.Rptr. 812]; Gilbert v. Sacramento Unified School Dist. (1968) 258 Cal.App.2d 505, 508-510 [65 Cal.Rptr. 913].) Thus neither case, nor section 44808 which followed them, in any way limits a school district’s responsibility to supervise students during school hours on school premises, and these authorities provide no aid to defendant in the instant case.³

Defendant strenuously argues that overwhelming policy considerations militate against the imposition of liability on a district in a case, such as this in which the injured pupil left the school voluntarily, “playing hooky.” Holding a school district liable for such an injuiy to a truant would lead, defendant urges, to “truant-proof’ schools, where, to avoid liability, school personnel would be required virtually to chain students to their desks to keep them from leaving. Defendant and amicus school districts spare no metaphor in portraying the fortress-like schools which would allegedly result from our holding that the instant plaintiffs have stated a cause of action against the instant defendant. The construction of these escape-proof schools would, it is stressed, be highly detrimental to education in this state.

The district’s fears in this regard are, however, clearly unwarranted since, as already noted, the district is not liable for an injury sustained by a truant under all circumstances, but rather is legally responsible only for those injuries which proximately result from the district’s failure to exercise “that degree of care ‘which a person of ordinary prudence, charged with [comparable] duties, would exercise under the same circumstances.’ ” (Dailey, supra, 2 Cal.3d at p. 747.) At trial, plaintiffs face the burden of showing that the district’s supervisory procedures fell below that degree of care which reasonably prudent persons would exercise, and the jury may well absolve the district of liability in this regard. We require ordinary care, not fortresses; schools must be reasonably supervised, not truant-proof.⁴

Finally, defendant argues that while a duty to supervise may arise during the school year, when attendance is compulsoiy, no such duty should be imposed during voluntary summer session. Defendant cites no authority for discarding the duty to supervise in summer session, and we find the proposed distinction artificial. Although a student may not be forced to enroll in summer school, once enrolled he must attend classes.

Additionally, the measure of the trust that parents place in the school to supervise their children is surely not diminished during summer. A large number of working parents enroll their children in summer school because they cannot afford alternative adult supervision. Surely these parents may legitimately expect adequate supervision. The following language from Satariano v. Sleight, supra, 54 Cal.App.2d 278, 284, is as relevant to summer session as to the regular school year: “We entrust the safety of our children to our public school authorities during school hours. They are bound to exercise an amount of care for their safety during that period commensurate with the immaturity of their charges and the importance of their trust.”

2. Whether or not defendant’s negligence proximately caused plaintiff’s injury is a question offact for the jury.

Although defendant primarily argues that a school district bears no “duty” to prevent off-campus injuries, it also claims that as a matter of law negligent on-campus supervision cannot be the proximate cause of an off-campus injury. Proximate cause, however, is generally a question of fact for the jury, and, as we explain, on the basis of the allegations in the instant case the trial court could not properly hold as a matter of law that defendant’s alleged negligent supervision on the campus did not proximately cause plaintiff’s off-campus injury. (See 4 Witkin, Summary of Cal. Law (8th ed. 1974) Torts, § 621, p. 2903 and cases cited therein.)

Defendant initially contends that it should not be expected to foresee that students will take advantage of a lapse in supervision to leave the school premises, and therefore that any off-campus injury is unforeseeable as a matter of law.⁵ Since at least the days of Huck Finn and Tom Sawyer, however, adults have been well aware that children are often tempted to wander off from schodl, and a jury might well conclude that defendants could have reasonably foreseen that this temptation might be especially strong during summer session when a student’s friends might not be in school. Indeed, the duty to supervise school children is imposed in large part in recognition of the fact that, without such, supervision, students will not always conduct themselves in accordance with school rules or as safely as they ought to. (See, e.g., Dailey v. Los Angeles Unified Sch. Dist., supra, 2 Cal.3d at p. 751; Satariano v. Sleight, supra, 54 Cal.App.2d at pp. 283-284.) Thus, we cannot say that Michael’s departure from school was unforeseeable as a matter of law.⁶

Defendant furthermore argues that the conduct of the motorcyclist who hit the plaintiff represents a “superseding cause” which cuts off any liability that the school district might bear for the accident. In Dailey, defendant school district pressed a similar argument, suggesting that the school’s negligent supervision was not a proximate cause of the injury because a third party wrongfully hit the plaintiff. We rejected that argument, noting: “[t]he fact that another student’s misconduct was the immediate precipitating cause of the injury does not compel a conclusion that negligent supervision was not the proximate cause of Michael’s death. Neither the mere involvement of a third party nor that party’s wrongful conduct is sufficient in itself to absolve the defendants of liability, once a negligent failure to provide adequate supervision is shown. [Citation.]” (Italics added; fn. omitted.) (2 Cal.3d at p. 750.)

As we explained in Akins v. County of Sonoma (1967) 67 Cal.2d 185, 199 [60 Cal.Rptr. 499, 430 P.2d 57], “where [an] injury was brought about by a later cause of independent origin . . . [the question of proximate cause] revolves around a determination of whether the later cause of independent origin, commonly referred to as an intervening cause, was foreseeable by the defendant or, if not foreseeable, whether it caused injury of a type which was foreseeable. If either of these questions is answered in the affirmative, then the defendant is not relieved of liability towards the plaintiff; if, however, it is determined that the intervening cause was not foreseeable and that the results which it caused were not foreseeable, then the intervening cause becomes a supervening cause and the defendant is relieved from liability for the plaintiff’s injuries.”

In the instant case, we certainly cannot say that the risk of a student’s injury at the hands of a negligent motorist is, as a matter of law, not a foreseeable risk created by a school district’s failure to exercise due care in supervising its pupils. (See, e.g., Taylor v. Oakland Scavenger Co., supra, 12 Cal.2d 310; Satariano v. Sleight, supra, 54 Cal.App.2d 278.) Thus, the subsequent negligence of the motorist does not necessarily relieve the district of all liability for the injury. Of course, under this court’s recent decision in American Motorcycle Assn. v. Superior Court (1978) 20 Cal.3d 578 [146 Cal.Rptr. 182, 578 P.2d 899], the school district is entitled to join the motorcyclist as a cross-defendant in the action in order to pursue a claim for comparative indemnity; thus, if the juiy determines that the motorcyclist is principally responsible for the injuries, he will be the party who will bear primary responsibility for the lion’s share of the damages.

In sum, the trial court’s decision sustaining defendant’s demurrer cannot be justified on the ground that defendant’s alleged negligence was not a proximate cause of plaintiff’s injuries as a matter of law. The proximate cause issue should properly have been submitted to the jury.

Accordingly, the trial court erred in dismissing plaintiffs’ action seeking recovery for Michael’s injuries.

3. Mary Ann’s causes of action for loss of Michael’s comfort and society and for her own injuries were properly dismissed.

Plaintiff Mary Ann Hoyem’s cause of action for her expenditures on Michael’s behalf was, like Michael’s own cause of action, improperly dismissed. Her other causes of action, however, for loss of Michael’s “comfort and society” and for her own injuries on viewing Michael in the hospital, are precluded by recent decisions of this court.

In Baxter v. Superior Court (1977) 19 Cal.3d 461, 463 [138 Cal.Rptr. 315, 563 P.2d 871], this court declined “to enlarge the parent’s cause of action to permit recovery for the loss of affection and society” when a child is injured. Maiy Ann’s cause of action on this score cannot stand.

Mary Ann also urges that this court extend the cause of action we recognized in Dillon v. Legg (1968) 68 Cal.2d 728 [68 Cal.Rptr. 72, 441 P.2d 912, 29 A.L.R.3d 1316], to include a plaintiff who suffers emotional and physical injury when seeing the primary victim of defendant’s negligence hours after the accident. In Dillon this court set out the rule that “courts should allow recovery to a mother who suffers emotional trauma and physical injury from witnessing the infliction of death or injury to her child for which the tortfeasor is liable in negligence.” (Italics added.) (68 Cal.2d at p. 730.)

The Court of Appeal in Deboe v. Horn (1971) 16 Cal.App.3d 221 [94 Cal.Rptr. 77] declined to extend the Dillon rule to include a wife who suffered emotional and physical injury when seeing her husband in the hospital hours after he had been injured in an automobile accident due to defendant’s negligence. Recently, in Justus v. Atchison (1977) 19 Cal.3d [139 Cal.Rptr. 97, 565 P.2d 122], we approved the Deboe opinion and denied recoveiy to an expectant father who was present in the delivery room when the fetus of his unborn child died, but who did not know of the death until later informed by doctors. We held in Justus that “Dillon requires more than mere physical presence: . . . the shock must also result from a ‘direct emotional impact’ on the plaintiff caused by ‘sensory and contemporaneous observance of the accident.’ ” (19 Cal.3d at p. 584.) Mary Ann’s Dillon cause of action, was therefore, properly dismissed.

4. Conclusion.

As explained above, California school districts have long borne a legal duty to exercise reasonable care in supervising students on school premises during school hours. In the present case, plaintiffs’ complaint alleges both that defendant breached this duty of care and that such negligence proximately caused Michael’s injuries. These allegations are sufficient to state a cause of action against the school district.

Contrary to defendant’s assertions, our holding in no way expands the supervisory obligations of school districts and does not place a new duty upon school authorities to control the conduct of students when they are off school premises. As we have explained, defendant’s liability in this case is posited not on an alleged failure to supervise Michael when he was off the school premises, but rather on an alleged failure to exercise due care in supervision on school premises. Defendant will be held hable for Michael’s injuries only if the jury concludes that defendant’s on-site supervision was negligent and that such negligence was a proximate cause of those injuries.

The judgment is affirmed insofar as it dismisses Mary Ann Hoyem’s causes of action for loss of Michael’s society and comfort and for personal injuries sustained as a result of viewing Michael’s injuries after the accident. In all other respects, the judgment is reversed. Plaintiffs shall recover their costs on appeal.

Bird, C. J., Manuel, J., and Newman, J., concurred.

1 Plaintiffs have filed a separate action against the driver of the motorcycle and the issue of the driver’s liability is not before us.

2 That the “reasonable care” exception in the statute is not accidental is clear from the legislative history. The original bill, passed by the Assembly, was identical to the current statute but did not include the final phrase about reasonable care. That phrase was added by Senate amendment (4 Sen. J. (1972 Reg. Sess.) p. 6247) and then approved unanimously by the Assembly. (4 Assem. J. (1972 Reg. Sess.) p. 7049.) The intent of the Legislature is clear: when a school district fails to exercise reasonable care the immunity of this section evaporates.

3 Defendant also relies on Castro v. Los Angeles Bd. of Education (1976) 54 Cal.App.3d 232 [126 Cal.Rptr. 537] which, in dicta interpreting the instant statute, states: “Students who participate in nonrequired trips or excursions ... are effectively on their own; the voluntary nature of the event absolves the district of liability.” (54 Cal.App.3d at p. 236.) Castro, however, is distinguishable from the instant case because it dealt not with an allegation that the school district failed to exercise reasonable care in supervising students on school premises, but with an accident occurring at a school-sponsored ROTC outing. The Castro court held the district liable because the activity was school-related.

4 Moreover, if the jury finds that the truant student’s negligence was a proximate cause of his injuries, defendant’s liability for such injuries will, of course, be diminished on the basis of comparative negligence principles. (See Li v. Yellow Cab Co. (1975) 13 Cal.3d 804 [119 Cal.Rptr. 858, 532 P.2d 1226, 78 A.L.R.3d 393].)

5 Defendant does not contend that the trial court could conclude that its alleged negligence was not an actual or “but for” cause of the accident as a matter of law. Plaintiff alleges that if defendant had provided adequate supervision, Michael would never have left the school premises and would not have sustained his subsequent injuries. On the basis of this pleading, the issue of actual causation is clearly a question of fact for the jury.

6 Although defendant argues that its negligent supervision should not be considered a proximate cause of the accident because the accident might easily have occurred at a time of day during which the district bore no duty of supervision, under traditional negligence principles such a speculative possibility cannot absolve the district of liability for the accident. Thus, in Dailey, for example, although the district could have similarly claimed that the slap-boxing incident might have occurred during nonschool hours, our opinion made clear that the district could be held liable so long as its negligent supervision was an actual (“but for”) cause of the injury and the general type of injury was reasonably foreseeable. (See 2 Cal.3d at pp. 750-751 and fn. 7.) The same principles apply here.
